Buzón Tributario Obligatorio, Evita Multas del SAT

Mandatory Tax Mailbox, Avoid SAT Fines

The mandatory tax mailbox is no longer a recommendation but a legally enforceable obligation for virtually all taxpayers in Mexico. Therefore, those who fail to activate it or keep their contact information updated face fines under Article 86-D of the Federal Tax Code. Furthermore, the 2026 Economic Package extended the electronic notification period from three to twenty business days, a change that directly benefits both individuals and businesses.

Below we explain who must comply, what requirements the SAT applies, and how to avoid penalties before the current extension ends.

What does it mean that the mandatory tax mailbox is now law?

The tax mailbox is the digital channel that the Tax Administration Service uses to notify taxpayers of administrative acts, requirements, and resolutions. For several years, it functioned as a rather optional tool in practice, even though the law had already contemplated it since 2014. However, this tolerance ended with the reform to the Federal Tax Code published in the Official Gazette of the Federation on April 9, 2016.

Following this reform, failing to activate the mailbox or keep contact information updated constitutes an independent infraction. Consequently, the SAT no longer relies on the taxpayer voluntarily checking the mailbox: the omission itself generates the penalty, regardless of whether or not there is a pending notification.

The reason why this change matters so much

It's important to note that the mandatory tax mailbox also redefines how the legal time limit for challenging an official action runs. For example, if a notification is deposited in the mailbox and the taxpayer never checks it because they haven't enabled it, the deadline for responding still begins. Thus, this omission not only results in a fine but can also cost the taxpayer the opportunity to defend themselves in time.

Who is required to enable the mandatory tax mailbox?

The obligation applies to both individuals and legal entities registered with the Federal Taxpayer Registry, regardless of their tax regime. It also applies to those who pay taxes under simplified regimes, which previously often fell outside the scope of active tax audits. For example, a professional operating under the digital platform regime must also enable this system, as must a small family business registered as a legal entity.

However, some recently registered taxpayers have a brief window to comply before automatic audits are activated. Meanwhile, those who already had a mailbox enabled under the previous rules should verify that their contact information is still valid, since a deactivated email address is practically equivalent to having no active mailbox.

Business groups with multiple RFCs

Groups operating under multiple legal entities face an additional challenge. Each entity within the group requires its own registered mailbox and verified contact information, making it impossible to centralize compliance in a single entity. This situation forces corporate tax departments to maintain an up-to-date inventory of Taxpayer Identification Numbers (RFCs) and the individuals responsible for each registration.

It's also worth mentioning the case of taxpayers who temporarily suspend their activities. Many assume that the suspension releases them from maintaining an active mailbox, but this assumption is incorrect. As long as the Taxpayer Identification Number (RFC) remains valid with the Tax Administration Service (SAT), the obligation to keep contact information updated continues, even without any transactions registered during that period.

Requirements: contact information and confirmation deadline

The SAT requires taxpayers to register at least one email address and a ten-digit cell phone number with a national area code. Furthermore, each contact method must be confirmed within 72 hours of registration using the code that the tax authority automatically sends. If this deadline expires without confirmation, the taxpayer must repeat the entire process.

In other words, simply capturing the data once is not enough: the system requires active validation, which many contributors forget to complete. For example, it's common for the code to arrive in the email and get lost among unread messages, forcing the user to request a new code and restart the count of hours.

Fines for non-compliance: Article 86-D of the Federal Tax Code

Article 86-D of the Federal Tax Code establishes the penalty for those who fail to activate the mandatory tax mailbox or fail to register and update their contact information. The fine ranges from 3,850 to 11,540 pesos, depending on the severity of the infraction and the taxpayer's history. Therefore, a micro-enterprise and a medium-sized company may face different amounts for the same omission.

Furthermore, this penalty is independent of any other consequences arising from missing notifications due to failure to check the mailbox. However, when the taxpayer did have the mailbox enabled but ignored a valid notification, the issue ceases to be a simple administrative fine and becomes a final act that can be very difficult to reverse.

Recidivism and aggravating factors

Similarly, the tax authority may consider repeated failure to update contact information an aggravating factor. For example, a taxpayer who has already been notified of the irregularity and does not correct the situation faces greater scrutiny in subsequent audits. Finally, it is important to remember that the fine does not exempt the taxpayer from the obligation: they must activate or update their mailbox regardless, in addition to paying the corresponding penalty.

Accounting firms often recommend checking the status of the tax mailbox as part of any company's annual tax audit, precisely because this omission often goes unnoticed until it causes a major problem. Since this review is so simple, it rarely justifies the cost of ignoring it.

The extension until 2027: what it really means

Although the infraction has existed since the reform of April 2026, the effective application of the penalty was postponed until January 1, 2027. This extension is provided for in the Fourth Transitory Article of the 2026 Miscellaneous Tax Resolution and its Annex 5, published in the Official Gazette of the Federation on December 28, 2025. Therefore, the SAT (Mexican Tax Administration Service) is not issuing fines generally for this reason during 2026, although it may do so from the aforementioned date.

However, interpreting the extension as a reason to postpone compliance is a common mistake. Consequently, any taxpayer who has not yet activated their mailbox faces January 1, 2027, as the actual deadline, not a suggestion. Furthermore, notifications that the SAT (Mexican Tax Administration Service) deposits in the mailbox during 2026 remain valid, even though the penalty for not activating it is not yet strictly enforced.

Another key change: notifications will take from three to twenty business days.

The 2026 Economic Package also modified the timeframe for taxpayers to be considered notified through their tax mailbox. Previously, the notification took effect just three days after its deposit, a period many considered insufficient to react. Now, that period has been extended to twenty business days, providing greater legal certainty for both individuals and businesses.

This adjustment is partly a response to years of litigation in which taxpayers argued they lacked a real opportunity to review their notifications. The tax authority, for its part, defended the change as a way to reduce conflict and improve the public's perception of the system. It's important to note that this longer timeframe does not replace the obligation to activate the mailbox; it simply provides more time once the notification has been properly delivered.

Tax mailbox versus other means of tax notification

Before digitization, the SAT (Mexican Tax Administration Service) primarily notified taxpayers via certified mail or by posting notices at its offices. Both methods remained in use to a limited extent, although the mandatory electronic tax mailbox became the preferred channel for the vast majority of administrative actions. Therefore, a taxpayer who only checks their postal mail risks missing notifications that were already submitted electronically weeks earlier.

The tax authority retains the power to post notices when the taxpayer's registered address cannot be located or when the mailbox is unusable due to reasons attributable to the taxpayer. However, this method is reserved for exceptional situations, not for the regular flow of notifications. Furthermore, physical postings require the interested party to appear in person to review them, which is far less practical than electronic notification accessible from any device.

What does this mean for the tax defense strategy?

Consequently, any modern tax defense strategy must be based on the premise that the tax mailbox is the primary source of information regarding actions by the tax authorities. Law firms that litigate tax matters routinely review their clients' mailboxes precisely because this is often where the first indication of an audit procedure appears before it is formalized through other means. Likewise, having timely access to the mailbox allows for preparing a defense from the earliest stages, rather than reacting belatedly to a decision that has already been made.

How to enable the mandatory tax mailbox step by step?

The first step is to log in to the SAT portal using the taxpayer's e.firma (electronic signature) or current password. Within the tax mailbox section, the platform requests the email address and cell phone number that will serve as official contact information. For example, it's advisable to use an email account that the responsible department checks daily, not a secondary inbox that is rarely accessed.

Second, the system sends a confirmation code to each registered contact method. This code must be entered within 72 hours, as explained previously. Finally, it's advisable to check the mailbox status every six months, as changes in personnel, cell phone numbers, or email providers can cause contact information to become outdated without anyone noticing immediately.

Best practices for medium and large companies

Similarly, companies with multiple RFCs (taxpayer identification numbers) must assign a clear person responsible for each authorization, ensuring that no entity within the group is left without an active mailbox due to lack of follow-up. Furthermore, it is advisable to internally document the date of each confirmation, providing internal evidence of compliance in case of a discrepancy with the tax authority.

Furthermore, it's advisable to establish an internal review schedule that doesn't rely on a single person's memory. A simple semi-annual reminder, formally assigned to the administration department or external accounting firm, significantly reduces the risk of staff changes leaving the inbox unattended for months. Finally, some companies choose to register an institutional email address instead of a personal one, precisely so that responsibility doesn't depend on the tenure of a specific employee within the organization.

Common mistakes and risks of not updating your mailbox

One of the most frequent mistakes is registering the email address of someone who no longer works at the company. Consequently, notifications arrive in an inbox that no one checks, even though the mailbox is officially enabled. This oversight creates the same practical risk as not having a mailbox at all, even if the company appears to be compliant from a formal standpoint.

Another common mistake is failing to verify that a registered cell phone number remains active after switching phone companies. For example, when a number is disconnected, confirmation codes stop arriving, and the taxpayer may not even realize their voicemail is invalid. However, both errors can be corrected with a simple periodic review that any administrative department can easily incorporate into its schedule.

A third, less obvious error is confusing the initial confirmation of the contact information with permanent validation. The SAT (Mexican Tax Administration Service) does not automatically request further confirmation as long as the information remains unchanged, creating a false impression that the process is permanently resolved. However, any subsequent update, such as a change of cell phone number, restarts the confirmation process and requires immediate attention within the corresponding 72-hour period.

Conclusion: Don't wait until January 2027

The mandatory tax mailbox already has legal consequences, even though the financial penalty is still under extension. Therefore, enabling it and keeping it updated is the simplest way to avoid both the fine and the risk of missing the deadline for filing a defense. Finally, it's worth remembering that the legal certainty gained with the new twenty-day period only benefits those who actually check their mailbox.

Between August 2026 and January 2027, there is a practical window to correct any omissions without the reputational cost of an ongoing audit. Taking advantage of this time, instead of waiting until the deadline, avoids surprises both in the company's finances and its legal defense schedule. A fifteen-minute review today can save weeks of unnecessary litigation tomorrow.

Incumplimiento de la Pensión Alimenticia… Tras el Criterio de la SCJN

Failure to pay child support… Following the Supreme Court's ruling

Failure to pay child support can result in criminal liability, not just civil, as confirmed by the Supreme Court of Justice of the Nation. In its session of January 7, 2026, the Court resolved Direct Appeals for Review 4627/2025 and 4632/2025. The Court upheld Article 201 of the Penal Code for the State of Morelos, which penalizes anyone who fails to pay court-ordered child support without justification. Therefore, those obligated to pay child support can no longer assume that a partial payment, made without judicial authorization, exempts them from criminal consequences. Consequently, both those entitled to and obligated to pay child support should be aware of the full scope of this ruling.

What did the Supreme Court of Justice of the Nation (SCJN) decide regarding non-compliance with child support payments?

The full court confirmed that the crime of failure to provide child support is compatible with the principle of minimal intervention in criminal law. Furthermore, it held that criminal intervention is valid when civil and family law mechanisms are insufficient to guarantee the effective payment of child support. In the two cases analyzed, the debtors made repeated deposits for amounts less than those ordered by the court. For this reason, the Court revoked the injunctions that both had obtained in previous instances.

It is important to note that the Court does not criminalize any genuine delay or financial hardship. On the contrary, it requires that any change in the amount of child support be formally requested from the family court judge. Otherwise, partial compliance without judicial authorization may result in criminal liability for the obligor.

The Case That Originated the Criterion: Partial Deposits Without Judicial Authorization

Two individuals were facing provisional child support payments ordered by a family court for their respective daughters. However, both made repeated deposits in amounts lower than those ordered by the court. Neither formally requested a reduction in the payments from the competent judge. Instead, they unilaterally decided to pay a different amount than the one stipulated.

For this conduct, both were prosecuted under the Penal Code of the State of Morelos. In previous proceedings, they obtained an injunction, arguing that the law was disproportionate. However, the Supreme Court overturned these favorable rulings. Finally, the full court confirmed that the crime was committed under the law in force in Morelos.

Context: Other Criteria on Children's Rights in the Same Session

This ruling was not an isolated case. On that same day, January 7, 2026, the Full Court, in Press Release No. 004/2026, resolved another case relevant to Mexican families. In Direct Amparo Appeal 7178/2024, the Court overturned a lower court ruling that had deemed a girl's child support obligation fulfilled thanks to the support of her maternal grandfather. The Full Court determined that this obligation belongs to the biological father and cannot be contingent upon the supportive conduct of other family members.

Además, la Corte precisó que exigir alimentos retroactivos no tiene naturaleza sancionatoria, sino que deriva de una obligación jurídica insustituible e irrenunciable. Al fijar montos retroactivos, los jueces deben analizar si el progenitor conoció el embarazo o el nacimiento, y la buena o mala fe con la que actuó. En conjunto, ambas resoluciones de esa sesión reafirman el mismo principio: el interés superior de la niñez exige el cumplimiento pleno de las obligaciones alimentarias, sin excepciones basadas en la solidaridad de terceros.

Legal Basis for the Crime of Child Support Non-Compliance

What does the Principle of Minimum Criminal Intervention require?

Criminal law should, in principle, be reserved for the most serious offenses that other branches of law cannot resolve. Therefore, the Court analyzed whether criminally sanctioning failure to provide child support respected this principle. It concluded that it did, given the serious risk it poses to the comprehensive development of children and adolescents.

The Best Interests of the Child as Justification

The Court emphasized that the best interests of the child require the full, timely, and continuous payment of child support. It also noted that civil remedies are insufficient when the debtor repeatedly acts in bad faith. Consequently, criminal proceedings are only pursued as a last resort in cases of persistent non-compliance.

How does this criterion affect you if you receive or pay child support?

If you are a child support recipient, this criterion strengthens your ability to demand full payment of the court-ordered support. For example, if the debtor makes partial payments without the judge's authorization, you can pursue criminal charges in addition to civil action. Furthermore, any change in the debtor's financial circumstances must be formally documented with the appropriate authority, not unilaterally.

If you are a child support debtor and experiencing genuine financial hardship, the recommendation is clear: request a modification of the support order from the family court judge before reducing the payment yourself. Likewise, keep documentary evidence of any changes in your financial situation, such as job losses, disability, or verifiable salary reductions.

Don't face this process alone. At Baráibar & Asociados, we have specialists in Family and Criminal Law ready to defend your interests in Mexico City.

Differences between the crime of Morelos and other State Penal Codes

It is worth clarifying that the crime of failure to pay child support is not defined identically throughout the country. Furthermore, each state has its own Penal Code, with different wording and penalties for this conduct. However, most of these codes share a central element: the requirement that the non-compliance lack reasonable justification.

For this reason, the First Chamber's ruling on Article 201 of the Morelos Constitution serves as a guide for similar cases in other states. Likewise, local courts often adopt this type of reasoning when interpreting their own state penal codes. Consequently, both creditors and debtors of alimony should review the specific legislation of their state, without assuming that the rules of Morelos automatically apply throughout Mexico.

What must the debtor prove to justify the non-compliance?

When a person obligated to pay child support faces genuine difficulties in fulfilling their obligations, the burden of proof falls on them. First, they must demonstrate the existence of an objective cause, such as job loss, medical incapacity, or a verifiable reduction in salary. Second, it is advisable to show that this cause arose after the support order was established, or that it was impossible to foresee.

Third, the debtor must demonstrate that they promptly requested a modification of the alimony payment from the family court, rather than reducing the payment unilaterally. Furthermore, judges place particular emphasis on the diligence with which the debtor acted in response to their new financial situation. Conversely, someone who simply stops paying without explanation or any formal procedure will find it difficult to provide a justifiable reason to the authorities.

What does “Without Justifiable Cause” mean according to the Court?

A central aspect of the ruling was the analysis of the phrase “without justifiable cause” within the criminal statute. The Court determined that this term is neither ambiguous nor does it violate the principle of legality in criminal law. On the contrary, it must be analyzed according to the specific circumstances of each individual case.

Among the relevant factors are the debtor's actual financial capacity, the existence of force majeure events, and any verifiable circumstances that prevent compliance. Furthermore, the debtor bears the burden of proving that they were unable to comply with the court-ordered alimony payment. Consequently, this flexible interpretation allows judges to evaluate each situation without resorting to excessive rigidity.

Civil and Criminal Consequences of Non-Compliance

Beyond criminal liability, unjustified non-compliance also has civil consequences. These include the seizure of assets, direct withholding of income, and arrest as a coercive measure in some cases. Family courts may also order additional precautionary measures to guarantee future payment.

For its part, criminal liability does not replace or exclude these civil consequences. Both avenues can coexist and be pursued simultaneously against the same debtor. Therefore, any defense strategy must consider the combined impact of both proceedings.

Role of Family Authorities in Monitoring Compliance

Family court judges, therefore, play a central role in preventing this crime. Furthermore, their timely intervention can prevent a civil breach from escalating into unnecessary criminal liability. For example, when a debtor requests a modification of alimony in a timely manner, the judge can assess their financial situation before a significant debt accumulates.

Likewise, many states maintain registries of delinquent child support debtors, linked to procedures such as obtaining passports or driver's licenses. Consequently, a debtor who ignores their obligations faces consequences that extend beyond the strictly familial sphere. In contrast, those who promptly contact the appropriate authorities retain greater control over their legal situation.

On the other hand, family court authorities can also order enforcement measures before the case escalates to criminal proceedings, such as arrest for repeated non-compliance. Similarly, they can authorize staggered payment agreements when the debtor demonstrates good faith and a willingness to comply. Consequently, both creditors and debtors benefit from timely communication with the family court, rather than waiting for the conflict to become fully litigated.

Practical Recommendations for Child Support Creditors and Debtors

First, every child support recipient should promptly document any non-payment or partial payment received. Then, it is advisable to immediately go to the family court to report the irregularity, without waiting for the arrears to accumulate. Likewise, it is recommended to seek specialized legal advice before initiating any criminal proceedings.

Similarly, any person obligated to pay child support should formally request any adjustment to the support order before modifying the payment on their own. Finally, it is advisable to keep all documentation that proves actual changes in the obligated person's financial capacity. Otherwise, the debtor could face criminal consequences, as confirmed by the Supreme Court.

A family lawyer can guide you through this process from the very beginning, representing both the creditor and the debtor. This early guidance often prevents unnecessary conflicts and reduces the risk of costly procedural errors. Families who manage these types of disputes with timely professional support generally achieve faster and less stressful resolutions for all parties involved.

How is a case of non-compliance documented before the Authority?

What the File Should Include

A solid case file begins with the court order or agreement that originally established the alimony amount. From there, it's advisable to gather deposit slips, bank transfers, or receipts that show the payments actually received. A chronological record, month by month, allows for clear identification of periods of non-compliance and discrepancies between the ordered and paid amounts.

Family lawyers often recommend keeping all direct communications with the debtor, such as messages or emails discussing alimony payments. This evidence is valuable both in civil proceedings and in any potential criminal charges. An organized file facilitates the judge's work, expedites the case resolution, and strengthens the alimony recipient's position against any defenses the debtor may attempt.

Why is it important to keep it updated and backed up?

Regularly updating this file also prevents the memory of the events from fading over time. Many cases drag on for months or even years before reaching a final resolution. For this reason, accurate and consistent record-keeping often makes the difference between a well-supported case and one vulnerable to challenges due to lack of evidence.

It is also advisable to digitize and back up each document on more than one storage medium. A physical file can be lost or damaged during a process that lasts several years. Therefore, maintaining chronologically organized digital copies makes it easier to share information with lawyers, experts, or authorities when the case requires it.

This provision is especially valuable in cases involving moves, changes of residence, or immigration processes for either party. An accessible digital file allows for continued case tracking without relying on physical documents that could become unavailable at a critical point in the proceedings. Furthermore, having this provision provides reassurance to families facing lengthy and arduous processes, knowing that the evidence gathered remains protected against any unforeseen circumstances.

Conclusion

The Supreme Court's ruling confirms that failure to pay child support can have real criminal consequences in Mexico. From this point forward, no parent obligated to pay child support can unilaterally reduce the court-ordered payment without judicial authorization. On the contrary, any change in economic circumstances must be formally documented before the competent judge. Creditor families thus gain an additional legal recourse against persistent non-compliance. Meanwhile, parents obligated to pay child support must act transparently to avoid unnecessary criminal liability.

Frequently Asked Questions (FAQs)

What did the Supreme Court of Justice of the Nation (SCJN) decide regarding non-compliance with child support payments?

The Plenary validated article 201 of the Penal Code of Morelos, which sanctions the unjustified non-compliance with alimony payments, in accordance with the Direct Appeals in Review 4627/2025 and 4632/2025, resolved on January 7, 2026.

Can a debtor reduce child support payments on their own?

No. Any adjustment must be formally requested from the competent family court judge. Reducing payments without judicial authorization may result in criminal liability, according to the precedent established by the full Court.

What does “without justifiable cause” mean in this crime?

The Court specified that it must be analyzed according to the circumstances of each case, considering the debtor's real economic capacity and any force majeure event verifiable before the competent authority.

What additional civil consequences exist for failing to pay alimony?

Seizure of assets, withholding of income and arrest as a coercive measure in some cases, which may coexist with criminal liability confirmed by the Supreme Court.

What should debtors with genuine financial difficulties do?

Request a modification of the pension before the family court judge and keep documentary evidence of your economic situation, instead of reducing the payment unilaterally and without authorization.

Where can I find the full Supreme Court ruling?

The criterion is found in Press Release No. 004/2026 of the SCJN and in the files of the Direct Amparo Appeals in Review 4627/2025 and 4632/2025, resolved on January 7, 2026.

Oposición de Acreedores en Fusiones Empresariales

Creditor Opposition in Business Mergers

La oposición de acreedores en fusiones empresariales ya cuenta con un respaldo constitucional expreso en México. Así lo confirmó el Pleno de la Suprema Corte de Justicia de la Nación, al resolver el Amparo en Revisión 50/2025 en sesión del 7 de enero de 2026. La Corte validó el artículo 224 de la Ley General de Sociedades Mercantiles, norma que permite a cualquier acreedor frenar judicialmente una fusión mientras se resuelve su reclamo. Por lo tanto, ninguna empresa puede asumir que un acuerdo de fusión, por sí solo, garantiza su ejecución inmediata. En consecuencia, los equipos jurídicos y financieros deben incorporar este riesgo a cualquier operación corporativa futura.

¿Qué Resolvió la SCJN sobre la Oposición de Acreedores en Fusiones Empresariales?

El Pleno confirmó que cualquier acreedor de las sociedades que se fusionan puede oponerse judicialmente, mediante juicio sumario, a esa operación. Además, mientras se resuelve la oposición, los efectos de la fusión quedan suspendidos por mandato legal. Esta suspensión no depende de un análisis previo sobre el fondo del reclamo del acreedor. En consecuencia, basta con que la oposición se presente dentro de los plazos legales para que la fusión quede detenida.

Cabe destacar que esta suspensión automática es, precisamente, lo que una sociedad mercantil impugnó ante los tribunales. La empresa argumentó que el artículo 224 limitaba, de forma indebida, su libertad de asociación. Sin embargo, el Pleno resolvió que esa libertad no es absoluta y que el Congreso puede establecer límites razonables. De ahí que la oposición de acreedores en fusiones empresariales se mantenga como una herramienta plenamente constitucional.

El Caso que Originó el Criterio: una Empresa Impugnó el Artículo 224

Una sociedad mercantil promovió amparo contra el artículo 224 de la Ley General de Sociedades Mercantiles, tras enfrentar la oposición de uno de sus acreedores a una fusión ya acordada. Argumentó que la norma vulneraba su libertad de asociación, reconocida por el artículo 9 constitucional. Además, sostuvo que la suspensión automática de los efectos de la fusión resultaba desproporcionada frente al interés legítimo del acreedor.

No obstante, el Tribunal Colegiado que conoció el asunto en primera instancia negó el amparo solicitado. La empresa recurrió esa negativa ante la Suprema Corte, mediante recurso de revisión. Finalmente, el Pleno confirmó la sentencia recurrida y negó el amparo de forma definitiva. Con esta resolución, la Corte fijó un precedente que impacta directamente a los grandes corporativos del país.

¿Cómo Funciona la Oposición Judicial a una Fusión Empresarial?

El Procedimiento Sumario de Oposición

Cualquier acreedor de las sociedades fusionadas puede iniciar este procedimiento ante un juez competente. El trámite se desahoga en la vía sumaria, pensada para resolver con celeridad. Mientras el juicio permanece abierto, la fusión no puede surtir efectos frente a terceros. Solo una sentencia firme que declare infundada la oposición permite reactivar la operación.

Alternativas para que la Fusión Surta Efectos de Inmediato

La propia ley prevé salidas para evitar esta suspensión. Por ejemplo, la sociedad puede pagar las deudas reclamadas por el acreedor inconforme. Asimismo, puede depositar el monto correspondiente en una institución de crédito autorizada. Por último, basta con obtener el consentimiento expreso de todas las personas acreedoras involucradas.

Contexto: Otros Criterios de la Misma Sesión del Pleno

La validación del artículo 224 no llegó sola. Ese mismo 7 de enero de 2026, el Pleno resolvió otros cuatro asuntos relevantes, agrupados en el Comunicado de Prensa No. 004/2026. Por un lado, confirmó que una persona juzgadora puede emitir una orden de aprehensión cuando el Ministerio Público acredite la “necesidad de cautela”, sin que exista aún auto de vinculación a proceso. Esa facultad, prevista en el artículo 141 del Código Nacional de Procedimientos Penales, exige justificar de forma detallada por qué otros medios menos invasivos resultan insuficientes.

Además, la Corte garantizó el derecho de niñas y niños a recibir alimentos de forma retroactiva, incluso cuando otro familiar haya asumido parte de su manutención. Igualmente, validó el delito de “negociaciones ilícitas” del Código Penal de Querétaro, aplicable a servidores públicos que obtienen beneficios indebidos en el ejercicio de su cargo. En conjunto, esta sesión refleja una agenda especialmente activa del Pleno en materia penal, familiar y corporativa.

Los Límites Constitucionales de la Libertad de Asociación

La Corte fue enfática: ningún derecho fundamental, incluida la libertad de asociación, opera sin límites. Por el contrario, el Congreso puede imponer restricciones razonables cuando exista una finalidad legítima que las justifique. En este caso, esa finalidad consiste en evitar que la desaparición de las sociedades fusionadas afecte el cobro de créditos legítimos. Igualmente, la Corte buscó impedir que el patrimonio de los acreedores se deteriore de forma injustificada durante el proceso.

Por su parte, este razonamiento se alinea con criterios previos sobre la función social de la propiedad y de la libertad contractual. Ninguna de esas libertades puede ejercerse en perjuicio de terceros con derechos legítimos de por medio. En consecuencia, las empresas deben diseñar sus operaciones corporativas considerando este equilibrio constitucional desde el inicio.

¿Qué Significa este Criterio para Fusiones y Adquisiciones en México?

En este contexto, cualquier proceso de fusión, adquisición o reestructuración corporativa en México enfrenta ahora un riesgo más visible: la oposición de acreedores en fusiones empresariales puede detener la operación por meses. Por ejemplo, un acreedor con un crédito relevante y sin garantías suficientes tiene ahora un incentivo claro para oponerse judicialmente. De no anticiparse, esa oposición puede retrasar el cierre de una operación estratégica y afectar su viabilidad financiera.

Además, los inversionistas y fondos que participan en operaciones de M&A en México deben incorporar este riesgo a sus análisis de due diligence. Un pasivo mal documentado, o un acreedor descontento, puede convertirse en un obstáculo legal real. Por esa razón, la etapa de planeación de cualquier fusión debe incluir un mapeo detallado de acreedores desde el principio.

No enfrentes este proceso solo. En Baráibar & Asociados contamos con especialistas en Derecho Corporativo y Mercantil listos para defender tus intereses en Ciudad de México.

Diferencia entre Fusión, Escisión y Adquisición frente a los Acreedores

Conviene distinguir entre estas figuras, pues el régimen de protección a los acreedores no opera igual en todas. Cabe señalar que la fusión implica que una o varias sociedades desaparecen para integrarse en otra, que asume la totalidad de sus derechos y obligaciones. Por esa razón, el artículo 224 de la Ley General de Sociedades Mercantiles regula específicamente este supuesto, dado el riesgo de que los créditos originales se diluyan.

La escisión, en cambio, divide el patrimonio de una sociedad entre varias entidades, cada una responsable de las obligaciones que le correspondan. Asimismo, la ley prevé reglas propias de responsabilidad solidaria para proteger a los acreedores en este escenario. Por su parte, una adquisición de acciones o activos no extingue a ninguna sociedad, por lo que el mecanismo de oposición judicial del artículo 224 no resulta aplicable de la misma manera. De ahí la importancia de identificar correctamente qué figura corporativa se está utilizando antes de diseñar la estrategia legal de la operación.

¿Qué Debe Contener un Mapeo de Acreedores Antes de una Fusión?

Un mapeo completo de acreedores debe incluir, primero, un listado detallado de todos los créditos vigentes, con montos exactos y fechas de vencimiento. Segundo, conviene clasificar a los acreedores según el riesgo real de que se opongan judicialmente a la operación. Tercero, resulta indispensable identificar si existen garantías reales o avales que respalden cada crédito.

Asimismo, el mapeo debe considerar la solidez de la relación comercial con cada acreedor. Un proveedor estratégico, por ejemplo, difícilmente se opondrá a una fusión que fortalece a su cliente. En cambio, un acreedor financiero con un crédito vencido y sin garantías representa un riesgo considerablemente mayor. Documentar esta clasificación con anticipación permite priorizar negociaciones y reducir sorpresas durante el proceso.

Riesgos y Contingencias para Empresas en Procesos de M&A

Cabe destacar que, entre los principales riesgos que enfrenta una empresa sin un plan de contingencia, se encuentran los siguientes: suspensión judicial de la fusión, retrasos que encarecen la operación, pérdida de confianza de inversionistas y exposición a litigios prolongados. De igual manera, una oposición mal gestionada puede filtrarse a medios y dañar la reputación de las partes involucradas.

Por otro lado, las fusiones transfronterizas enfrentan un riesgo adicional. Los acreedores extranjeros también pueden ejercer este derecho de oposición conforme a la ley mexicana, siempre que la sociedad deudora esté constituida en el país. Por tanto, las empresas con operaciones internacionales deben revisar sus contratos de crédito vigentes antes de anunciar cualquier fusión.

Impacto para Empresas con Contratos de Crédito y Fideicomisos de Garantía

Las empresas que operan con fideicomisos de garantía o contratos de crédito estructurado enfrentan un escenario particular frente a este criterio. Muchos de esos instrumentos incluyen cláusulas de vencimiento anticipado, activables precisamente ante un proceso de fusión. Por lo tanto, una oposición judicial no solo suspende la fusión, sino que puede detonar, de forma simultánea, el vencimiento de otras obligaciones financieras relacionadas.

Asimismo, las instituciones bancarias suelen exigir notificación previa de cualquier fusión que involucre a su acreditado. Omitir ese aviso, incluso sin mala intención, puede generar un incumplimiento contractual independiente del criterio de la Corte. Por esa razón, conviene revisar cuidadosamente los contratos de crédito vigentes antes de anunciar públicamente cualquier operación corporativa.

De igual manera, los fideicomisos de garantía suelen designar a una institución fiduciaria como representante de los acreedores. Esa institución puede oponerse judicialmente en nombre de todos los beneficiarios del fideicomiso, lo que concentra un riesgo considerable en una sola contraparte. En consecuencia, negociar directamente con el fiduciario, antes de anunciar la fusión, puede evitar una oposición que afecte a decenas de acreedores simultáneamente.

Recomendaciones de Compliance Corporativo para Evitar Oposiciones de Acreedores

En primer lugar, toda empresa que planee una fusión debería elaborar un inventario completo de acreedores y sus condiciones de pago. Después, conviene evaluar cuáles de esos créditos representan un riesgo real de oposición judicial. Asimismo, resulta prudente negociar anticipadamente con los acreedores más relevantes, antes de anunciar públicamente la operación.

Igualmente, conviene documentar por escrito cualquier acuerdo de pago, garantía o consentimiento obtenido de los acreedores. Finalmente, es recomendable incorporar cláusulas contractuales que anticipen escenarios de fusión futura, reduciendo así la incertidumbre legal. De lo contrario, la empresa podría enfrentar demoras costosas como las que motivaron esta resolución.

Asimismo, un comité interno de seguimiento, integrado por las áreas legal, financiera y de tesorería, facilita la coordinación durante todo el proceso. Ese comité puede detectar oportunamente señales de alerta, como un acreedor insatisfecho o una comunicación tensa con algún proveedor relevante. Las empresas que institucionalizan este tipo de revisión suelen enfrentar procesos de fusión considerablemente más ágiles y predecibles.

¿Qué Plazo Tiene un Acreedor para Oponerse a la Fusión?

La ley establece un plazo específico para ejercer este derecho, contado a partir de la publicación del acuerdo de fusión. Los acreedores deben actuar dentro de ese periodo si desean activar la suspensión judicial prevista en el artículo 224. Una vez vencido ese plazo, la fusión puede surtir efectos plenos frente a terceros, salvo situaciones excepcionales previstas en la propia legislación mercantil.

Por su parte, este plazo obliga a las empresas a publicar el acuerdo de fusión con exactitud y transparencia, conforme a los requisitos legales aplicables. Un balance general incompleto, o una publicación con errores, puede generar disputas adicionales sobre el momento exacto en que el plazo comenzó a correr. Los abogados corporativos recomiendan documentar cuidadosamente la fecha y el medio de publicación, para evitar controversias posteriores sobre el cómputo del término legal.

La certeza sobre este plazo también protege a la propia empresa fusionante frente a reclamos extemporáneos. Un acreedor que se opone fuera de tiempo carece de fundamento legal para suspender la operación, sin importar la legitimidad de su crédito original. Por ese motivo, contar con evidencia clara de la fecha de publicación resulta tan importante como la solidez del propio acuerdo de fusión.

De ahí que convenga conservar acuses de recibo, capturas de pantalla y constancias notariales de cada publicación relacionada con la fusión. Además, un abogado corporativo puede calcular con precisión el vencimiento del plazo aplicable a cada acreedor conocido. En consecuencia, esta previsión adicional reduce sensiblemente el margen de disputa sobre la oportunidad de cualquier oposición futura.

Conclusion

El criterio del Pleno confirma que la oposición de acreedores en fusiones empresariales es una herramienta legal plenamente vigente en México. A partir de esta resolución, ninguna empresa puede subestimar el riesgo que representa un acreedor inconforme durante un proceso de fusión. Por el contrario, cada operación corporativa debe planearse considerando este riesgo desde su diseño inicial. Las empresas que actúen con anticipación reducirán su exposición a suspensiones judiciales y retrasos costosos. En cambio, quienes ignoren este criterio podrían enfrentar contingencias similares a la que motivó la intervención de la Suprema Corte.

Prestaciones de Vivienda Alternas al Infonavit

Housing Benefits as Alternatives to Infonavit

Housing benefits offered as alternatives to Infonavit can no longer simply replace the legal obligation to contribute to the institute. This was determined by the full Supreme Court of Justice of the Nation on August 3, 2026, in its ruling on Amparo Appeal 633/2026. The case arose from a claim by a retired Pemex employee who demanded recognition of his unpaid contributions. Therefore, this ruling mandates a thorough review of any internal housing program offered by a company as a substitute for legal contributions. Consequently, legal and human resources directors must take action before the issue escalates to litigation.

What did the Supreme Court of Justice of the Nation (SCJN) decide regarding alternative housing benefits to Infonavit?

The full Court confirmed that the benchmark for evaluating any alternative housing system is the Infonavit Law, along with Article 136 of the Federal Labor Law. It is not sufficient, therefore, for a company's internal regulations to provide benefits such as rental assistance or support for acquiring a home. Furthermore, the courts must expressly compare these extra-legal benefits against the legal framework that protects the right to housing. Only in this way can it be determined whether the scheme offers benefits equal to or greater than those required by law. Otherwise, the company remains obligated to make the corresponding contributions to the National Workers' Housing Fund Institute (Infonavit).

It is worth noting that this ruling stems from a labor matter, but its scope extends beyond the energy sector. Any Mexican company with its own housing benefit schemes that operate as alternatives to Infonavit now faces the same standard of review. Furthermore, the ruling confirms that an internal work regulation, by itself, does not replace the constitutional obligation established in Article 123, Section A, Paragraph XII.

Background: The Case of a Retired Pemex Worker

A former Pemex employee filed a labor lawsuit claiming various benefits that were not provided during his employment. Among these, he demanded recognition and payment of the contributions omitted from his Infonavit (National Workers' Housing Fund Institute). In the first instance, the labor authority ordered the company to register him with the IMSS (Mexican Social Security Institute) and make the corresponding contributions. However, a collegiate court overturned that ruling, considering that Pemex's Regulations for Management Personnel provided for their own housing system.

Articles 47 and 76 of this regulation provide for benefits such as housing allowances and financial support for home purchases. For this reason, the collegiate court determined that Pemex was exempt from contributing to Infonavit. However, the worker appealed this decision to the Supreme Court. Ultimately, the full court overturned the lower court's ruling and returned the case to the collegiate court for a new decision, this time in accordance with the parameters established by the Supreme Court.

Why are Internal Regulations Not Enough to Replace Infonavit?

The Legal Parameter: Infonavit Law and Article 136 of the LFT

The Court was clear: no internal regulations can supersede the legal social security system. On the contrary, any alternative scheme must be measured against the Infonavit Law and Article 136 of the Federal Labor Law, which establishes the employer's obligation to contribute to the housing fund. Therefore, housing benefits that are alternatives to Infonavit are only valid when they offer a benefit equal to or greater than the legally mandated one. Likewise, the company must demonstrate this equivalence with objective and verifiable data, not with a mere contractual declaration.

The Mandatory Comparison Between Extralegal and Legal Benefits

Collegiate courts can no longer simply verify the existence of internal regulations regarding housing benefits. Instead, they must conduct an explicit comparative analysis between the two systems. For example, if the rental assistance offered by a company is less than the amount it would contribute to Infonavit, the alternative scheme does not meet the constitutional standard. In that case, the company must regularize its contributions and could face tax penalties, surcharges, and interest adjustments.

Other Criteria of the SCJN in the Same Session of August 3, 2026

The ruling on alternative housing to Infonavit was not the only one issued. That same day, the full court resolved three other matters of importance to businesses and individuals. First, it confirmed that declarations of Protected Natural Areas are a valid form of property ownership, without triggering the right to a prior hearing under Article 14 of the Constitution. Second, it upheld the constitutionality of the desk audits provided for in the Social Security Law, considering them an act of intrusion in accordance with Article 16 of the Constitution.

Additionally, the Plenary established binding precedent requiring collegiate courts to assume full jurisdiction when ruling on suspensions in direct amparo proceedings, when the omission of the responsible authority is deemed justified. Taken together, these rulings demonstrate a particularly active session regarding economic, social, and procedural rights, with a direct impact on the relationship between companies, authorities, and workers.

Impact on State-Owned Enterprises and the Energy Sector

The origin of this legal precedent in a case against Pemex is not accidental. For decades, various state-owned enterprises and parastatal entities have had internal regulations offering housing benefits alternative to Infonavit (the Mexican National Housing Fund) to their management personnel. For example, the Federal Electricity Commission (CFE) and other entities in the energy sector maintain similar schemes, inherited from historical collective bargaining agreements. Consequently, these entities now face the same requirement for documented comparison with the legal framework.

Similarly, private companies operating under specialized outsourcing schemes or that inherited personnel management regulations from other public entities must review their situation. Therefore, it is not enough to argue that a scheme “has always worked this way”; the Court now requires technical and comparative support, updated according to the realities of the real estate market in each region of the country.

What does this criterion mean for companies with their own housing schemes?

Numerous Mexican companies, particularly in the energy, industrial, and service sectors, offer housing benefits as alternatives to Infonavit as part of their compensation packages. However, very few have formally documented the equivalence between these benefits and the legal system. For this reason, the Supreme Court's ruling represents an urgent call for self-evaluation. Failure to do so leaves the company vulnerable to a claim for retroactive payment of unpaid contributions by an employee at any point during the employment relationship or even after retirement.

Furthermore, the issue is not limited to the workplace. There is also a significant tax risk, as Infonavit can determine credits for omitted contributions, with interest and penalties that accrue over time. For their part, affected workers retain the option of pursuing legal action to demand recognition of their rights, as occurred in the case resolved by the full court.

Statute of Limitations and Time Limits for Claiming Omitted Contributions

It is important to remember that labor actions related to social security benefits are subject to statutes of limitations. As a general rule, the Federal Labor Law establishes a one-year period to demand compliance with benefits arising from the employment relationship, counted from the date the obligation became due. However, regarding contributions to Infonavit (the Mexican National Housing Fund), various judicial rulings have modified this period, especially when the omission is continuous throughout the entire employment relationship.

For this reason, a company should not assume that the passage of time automatically protects it from claims like the one resolved by the Plenary. Instead, it is advisable to address the contingency proactively, before an active or retired employee decides to assert their rights in labor courts.

Risks of Non-Compliance Regarding Alternative Housing to Infonavit

Among the main risks a company faces without documented comparisons are the following: tax credits for omitted contributions, accumulated updates and surcharges, individual or collective labor lawsuits, and reputational damage with investors and authorities. Similarly, a poorly designed scheme can generate contingent liabilities that affect audit processes, mergers, or acquisitions.

On the other hand, companies operating under collective bargaining agreements should review whether their housing clauses comply with the standard set by the Court. In many cases, these clauses were drafted years ago, without updating their amounts to reflect inflation or the actual cost of housing in Mexico. This outdated information increases the risk that the benefit will be less than the legally mandated amount. Similarly, in mergers and acquisitions, contingent liabilities for omitted contributions often emerge as significant findings during labor due diligence, which can affect the final transaction price. Therefore, mergers and acquisitions teams should incorporate this criterion as a standard part of their checklist before closing any deal.

Don't face this process alone. At Baráibar & Asociados, we have specialists in Labor and Corporate Law ready to defend your interests in Mexico City.

Labor Compliance Recommendations for 2026

First, every company offering housing benefits other than those provided by Infonavit should commission a comparative audit of its internal regulations against the Infonavit Law. Next, it is advisable to document in writing the technical analysis that supports the equivalence of benefits, using updated figures and objective criteria. Likewise, it is prudent to review collective bargaining agreements and individual labor contracts to verify that the housing clauses reflect current and reasonable amounts.

Similarly, it is advisable to establish an internal mechanism for periodic review, preferably annual, to update the amounts of alternative benefits as housing costs evolve. Finally, it is recommended to train the human resources department on this new jurisprudential standard so that any future benefits are designed in accordance with the parameters validated by the Court. Otherwise, the company will remain vulnerable to litigation like the case that prompted this ruling.

What Should a Housing Benefits Comparison Report Contain?

A technical comparison report should include several specific elements. First, a detailed list of the housing benefits currently in effect under the company's internal regulations, with exact amounts and payment schedules. Second, a calculation of the corresponding contribution under the Infonavit Law for the same group of workers, considering their base salary for social security contributions. Third, a comparative table showing, month by month, the difference between the two schemes.

The report must also identify workers covered by the alternative scheme, distinguishing between management, unionized, and retired personnel. Labor lawyers recommend updating this document every fiscal year, given that minimum wages and contribution caps change periodically. A regulation that has been in effect for several years likely no longer reflects current housing market conditions.

Companies with operations in multiple states face an additional challenge: housing costs vary significantly across regions. A uniform national benefit might be sufficient in some cities but insufficient in others, particularly in metropolitan areas with high real estate demand. Documenting this regional variation strengthens the company's defense against any subsequent review, whether administrative or judicial.

How to proceed if your company offers housing benefits other than Infonavit?

If your company has its own housing program, the first step is to gather all the necessary documentation for the benefit: amounts, frequency, covered population, and eligibility requirements. Next, it's advisable to compare this information with the requirements of the Infonavit Law for the same group of workers. If a discrepancy is identified, the company can choose to adjust the program, supplement it, or switch to regular contributions.

Furthermore, this review should be carried out with specialized legal support, as it involves labor, social security and, sometimes, tax regulations.

Conclusion

The Supreme Court's ruling marks a turning point for alternative housing benefits to Infonavit in Mexico. From now on, no internal regulation alone will be sufficient to exempt a company from its legally mandated contributions. On the contrary, each scheme must demonstrate, with objective data, that it offers benefits equivalent to or greater than those required by law. Companies that act proactively will reduce their exposure to litigation, tax liabilities, and labor disputes. Conversely, those that ignore this ruling could face claims similar to the one that prompted the Supreme Court's intervention.

Derecho de Admisión en Escuelas Privadas

Right of Admission to Private Schools

The right of admission to private elementary schools can no longer be exercised arbitrarily in Mexico. This was established by the First Chamber of the Supreme Court of Justice of the Nation through Jurisprudential Theses 1a./J. 15/2024 and 1a./J. 17/2024. Both rulings stem from Amparo Appeal 57/2022, decided on January 25, 2023, under the opinion of Justice Jorge Mario Pardo Rebolledo. Therefore, no private elementary school can openly and arbitrarily reserve the right to admit or reject students. Consequently, parents and educational institutions must be aware of the true scope of this ruling.

What Does the Thesis Say About the Right of Admission in Private Schools?

The First Chamber determined that no private educational institution at the basic education level may adopt normative, advertising, contractual, or de facto positions. Such positions cannot openly reserve the right of admission to students. On the contrary, access to these institutions must be granted under conditions of equal opportunity and non-discrimination. Furthermore, the Court specified that the social repercussions of a reserved admission policy affect the right to education, protected by Article Three of the Constitution. It also affects the best interests of the child, protected by Article Four.

La Corte reconoció algo que muchas familias intuían desde hace años. “El prestigio de un colegio no puede traducirse en la facultad de discriminar libremente a quién admite y a quién no”, señala el especialista. Esta reflexión resume el espíritu del criterio, orientado a equilibrar la libertad contractual de las escuelas con los derechos fundamentales de niñas, niños y adolescentes.

Background of the Litigation that Gave Rise to the Criterion

The case reached the Supreme Court through an appeal for review, filed against the denial of enrollment for a family at a private school. During the litigation, it was argued that the school had exercised its right of admission without further justification. However, the First Chamber considered this argument insufficient in light of the constitutional rights at stake. For this reason, the analysis focused on the General Law of Education and the obligations it imposes on private entities.

This law establishes the duty of private educational institutions to avoid compromising equal treatment of students. It also empowers the federal education authority to issue regulations governing school administration in basic education. These regulations must facilitate enrollment, re-enrollment, accreditation, promotion, regularization, and certification of studies. Therefore, the Court concluded that reserving the right of admission without objective and verifiable criteria violates this legal framework.

Constitutional Basis of the Right of Admission to Private Schools

Article Three: The Right to Education

Article Three of the Constitution recognizes the right of every person to receive an education. Therefore, any practice that hinders access to this right, even if carried out by private entities, is subject to constitutional review. In this regard, the Court emphasized that basic education is of a public interest that transcends the contractual relationship between the school and the family.

Article Four: The Best Interests of the Child

Article Four of the Constitution, for its part, mandates that all decisions concerning children and adolescents must consider their best interests. Likewise, the General Law on the Rights of Children and Adolescents requires adults to adopt measures that promote and protect these rights. This obligation extends to private institutions. Consequently, a refusal of admission without objective justification violates this constitutional standard.

Background: The Debate on Discrimination in Access to Private Services

This criterion did not arise in isolation. Over the past decade, various courts have analyzed whether private entities, when providing services, can arbitrarily deny access. The Federal Law to Prevent and Eliminate Discrimination has long recognized that denying a service for discriminatory reasons constitutes a legal violation. These reasons include ethnic origin and social status, among other protected categories. However, in the case of basic education, the Court added an additional element: the best interests of the child. This element strengthens protection against arbitrary decisions.

Therefore, this criterion aligns with a growing body of case law that expands constitutional oversight of the actions of private entities. This oversight applies when they provide services of public interest, such as education, healthcare, or transportation. Consequently, private schools cease to operate under a purely contractual framework and become subject to the same standards of equality as public institutions.

What can other service sectors learn from this criterion?

Although the thesis specifically addresses basic education, its reasoning is useful for other sectors that serve the general public. Sports clubs, daycare centers, private clinics, and membership platforms face similar questions about the limits of their contractual freedom in relation to the rights of their users. For example, denying access to a service without objective and documented criteria can generate liability, even outside the educational sphere, when fundamental rights are at stake.

In fact, the Federal Law to Prevent and Eliminate Discrimination already includes sanctions for service providers who deny access for discriminatory reasons. However, this ruling by the First Chamber strengthens that protection by directly linking it to the best interests of the child, thus raising the bar for any institution that serves minors, beyond the strictly educational sector.

How does this criterion affect you if you are trying to register a minor?

If your family applies to enroll a child in a private elementary school, the institution can no longer deny admission without objectively explaining the reasons. For example, it is not enough to invoke a generic "right of admission reserved" clause in the contract or in the school's advertising. Instead, the school must demonstrate reasonable, verifiable, and non-discriminatory criteria, such as available space or academic requirements clearly communicated in advance.

Likewise, if you believe your family was arbitrarily rejected, you can pursue legal action to demand respect for this legal precedent. Similarly, local and federal education authorities have oversight mechanisms for the school regulations that private institutions must follow. Additionally, the National Council to Prevent Discrimination can receive complaints when a denial of admission masks unequal treatment based on categories protected by law.

Don't face this process alone. At Baráibar & Asociados, we have specialists in Educational and Constitutional Law ready to defend your interests in Mexico City.

What clauses should schools avoid in contracts and advertising?

Many private schools still include clauses such as “the institution reserves the right of admission” in their enrollment contracts or in their print and digital advertising. These types of clauses, drafted generically and without objective criteria, directly contravene the ruling of the First Chamber. For example, denying admission to a minor based on their appearance, perceived socioeconomic status, or family structure, without documentary evidence, constitutes an arbitrary refusal of admission.

However, clauses establishing quota limits per group, academic requirements applicable equally to all applicants, or objective and transparent psycho-pedagogical evaluation processes are valid. Therefore, the central difference lies in the objectivity and uniform application of the criteria, not in the very existence of a selection process.

Documents that a School Must Keep to Accredit Objective Criteria

An educational institution wishing to avoid legal issues must maintain documentary evidence of its admissions processes. Each applicant's file should include the application form, the results of any administered assessments, and all communications sent to the family. The criteria for available spaces per group must also be recorded, along with the date of the last update and the person responsible for defining them.

Schools with psychoeducational assessment processes need clear protocols outlining what each instrument measures and how the results are interpreted. An instrument administered without a transparent methodology can be interpreted as a hidden barrier to admission, particularly if its results disproportionately exclude certain groups of applicants. School principals should receive regular training on these standards, given that admission decisions are often made at the school level, without direct legal oversight.

Institutional advertising deserves special attention. School brochures, websites, and social media should not suggest, even implicitly, that certain types of families are welcome and others are not. Regularly reviewing these materials, with legal counsel, significantly reduces the risk of a complaint or lawsuit succeeding. Maintaining evidence of this review also constitutes valuable documentary evidence against any future claims.

Implications for Private Educational Institutions

Private elementary schools should review their internal regulations, enrollment contracts, and advertising materials to eliminate any clauses that reserve the right to admit students in an open or arbitrary manner. Furthermore, they should document objective selection criteria, where they exist, such as enrollment limits or academic requirements that apply equally to all applicants.

Las instituciones educativas que actúen con transparencia en sus procesos de admisión no solo cumplen la ley, sino que fortalecen la confianza de las familias en su comunidad escolar. Por lo tanto, más que una limitante, este criterio representa una oportunidad para profesionalizar los procesos de ingreso.

Differences between Basic Education and Other Educational Levels

It is worth clarifying that this thesis focuses specifically on basic education, given the paramount importance of children's well-being. In contrast, upper secondary and higher education levels could allow for greater discretion, provided that objective and non-discriminatory academic criteria exist, such as standardized entrance exams or minimum grade point averages. Nevertheless, the general principle of equality of opportunity remains a relevant reference point for any educational level.

Furthermore, private universities retain greater autonomy in designing their selection processes, by virtue of their constitutionally recognized academic freedom. However, even within this context, discrimination based on factors other than academic merit remains prohibited under the Federal Law to Prevent and Eliminate Discrimination. Therefore, all educational institutions, regardless of their level, must avoid practices that exclude applicants based on subjective or discriminatory criteria.

High schools, for example, typically administer standardized entrance exams with publicly available rules and predetermined minimum scores. This type of mechanism, in principle, meets the standard of objectivity required by jurisprudence. Universities, on the other hand, document their selection processes through public calls for applications, which makes it easier to demonstrate the absence of arbitrariness in any subsequent review.

Practical Recommendations for Families and Institutions

First, families should request in writing the reasons for any enrollment rejection. Then, they should keep all advertising materials, contracts, and communications related to the admissions process. For their part, educational institutions should train their administrative staff on this criterion so that enrollment processes comply with the standards set by the Court.

Similarly, it is advisable that schools update their enrollment contracts with the support of specialized legal counsel, replacing generic clauses with objective and verifiable criteria. Finally, both families and schools can benefit from preventative legal advice, which anticipates conflicts and reduces the risk of unnecessary litigation.

Conclusion

With these principles, the right of admission to private schools has found a clear limit against arbitrariness. Based on this criterion, no institution at the basic education level can reject applications without objectively justifying its reasons. On the contrary, equal opportunities and non-discrimination become the mandatory standard for any enrollment process. Families thus gain a solid legal tool against arbitrary decisions. Meanwhile, educational institutions must adapt their processes to avoid legal contingencies and strengthen the trust of the school community.
