Alimony Court Claim Mexico (Demanda de Pensión Alimenticia)

An Alimony Court Claim Mexico (Demanda de Pensión Alimenticia) is a judicial petition filed before the competent Juzgado de lo Familiar seeking a court order compelling a person with a legal alimentary obligation (deudor alimentario) to provide financial support (pensión alimenticia) to a beneficiary (acreedor alimentario) who has been denied the support they are legally entitled to. The action is governed by the substantive provisions of Articles 301 through 323 of the Código Civil Federal (CCF) — which establish who owes alimentos, to whom, in what amount, and under what circumstances — and the procedural framework of the Código Nacional de Procedimientos Civiles y Familiares (CNCPF), published in the Diario Oficial de la Federación on 7 June 2023, specifically Article 604 governing family proceedings.

The concept of alimentos in Mexican law is broader than the English-language equivalents of 'child support' or 'alimony.' Article 308 CCF defines alimentos as encompassing: food and nutrition (sustento); clothing and shelter (vestido y habitación); medical care (atención médica); educational expenses including school fees, uniforms, books, and extracurricular activities for minor children (educación e instrucción); and pregnancy and postpartum care for the mother (gastos de embarazo y parto). For adult children with disabilities or those pursuing higher education, the scope of alimentos may extend further under Article 303 CCF and LGDNNA Article 103.

The alimentary obligation arises from specific family relationships enumerated in Article 301 CCF: (i) spouses owe each other alimentos during the marriage; (ii) parents owe alimentos to their minor and disabled children under Articles 303 and 304 CCF; (iii) adult children owe alimentos to parents who lack the means to support themselves; (iv) siblings owe alimentos to each other when in extreme need; and (v) the alimentary obligation extends reciprocally to grandparents, uncles, nephews, and cousins in the order of kinship proximity established in Articles 305–307 CCF. The obligation of parents to their minor children is the strongest in the hierarchy — it cannot be waived and does not depend on the parents' marital status, since patria potestad and alimentary obligations arise from filiation (filiación), not matrimony.

Article 311 CCF establishes the two factors that determine the amount of pensión alimenticia: (i) the necesidades del acreedor (needs of the beneficiary — their reasonable expenses for food, housing, education, medical care, and other necessities considering their age, health, and established standard of living); and (ii) la posibilidad económica del deudor (the payer's economic capacity — income, assets, and financial obligations). The court balances these two factors to arrive at a proportional and equitable amount. Mexican courts have developed extensive jurisprudencia through the Suprema Corte de Justicia de la Nación (SCJN) on the methodology for determining pensiones alimenticias, including Tesis 1a./J. 25/2012 on the minimum quantum of child support and principles for income verification.

A distinctive feature of Mexican alimony law is the aviso de retención — a court order issued to the deudor alimentario's employer (patrón) under Article 317 CCF directing the employer to deduct the pensión alimenticia from the employee's salary at source and remit it directly to the court or the beneficiary. This wage garnishment mechanism is highly effective where the deudor is an employee registered with IMSS — the court can identify the employer through IMSS registry records and the employer faces civil and criminal liability for non-compliance with the retention order. Article 336 CCF makes abandonment of alimentary obligations a criminal offence (abandono de familia) punishable under the Código Penal Federal.

The CNCPF introduced oral adversarial family procedure for alimony claims, replacing the prior written procedure of the Código de Procedimientos Civiles para el Distrito Federal. Critically, Article 604(III) CNCPF provides for provisional alimony (alimentos provisionales) to be ordered simultaneously with admission of the demanda — the court can decree a provisional pension without waiting for trial, based on documented income evidence, protecting the beneficiary during the pendency of the proceeding.

An Alimony Court Claim Mexico is required when a person who has a legal alimentary obligation under the Código Civil Federal — a parent, spouse, or other relative in the statutory kinship hierarchy — has refused, neglected, or is unable by agreement to voluntarily provide adequate financial support for their dependent family members.

The demanda de pensión alimenticia is most commonly needed when parents separate or divorce and one parent — typically the one without primary custody of the minor children — stops or reduces financial contributions to the children's expenses, forcing the custodial parent to seek judicial determination of the pensión. Article 303 CCF establishes that parents owe alimentary obligations to their children regardless of whether the parents were married — children born outside of marriage have identical alimentary rights once filiation is legally established through recognition (reconocimiento) or judicial filiation (investigación de paternidad).

The petition is required when a separated or divorcing spouse who was economically dependent on their partner — having dedicated themselves to the household (trabajo del hogar) and childcare — finds themselves without income and requires court-ordered support pending and following the dissolution of the marriage. Article 162 CCF imposes mutual spousal support obligations during marriage, and Article 288 CCF provides for post-divorce compensation in certain circumstances.

An independent pensión alimenticia demanda (separate from a divorce proceeding) is necessary when the parents have never married and paternity is either acknowledged or has been judicially established, but the non-custodial parent refuses to contribute to the child's expenses. The court can order pensión even before or without a divorce proceeding.

The action is urgently needed when the deudor alimentario has stopped payments without judicial modification — unilateral cessation of support is illegal regardless of changed circumstances; the payer must petition the court for modification (reducción or extinción de la pensión) and must continue paying the existing amount until the court orders otherwise.

The demanda is also appropriate when an adult child with a permanent disability — physical or mental incapacity preventing self-support — requires continued parental support beyond the age of majority under Article 303 CCF and LGDNNA Article 57.

In cases of urgency and immediate danger of the beneficiary going without adequate food, shelter, or medical care, the plaintiff may request medidas cautelares (provisional alimony) simultaneously with the demanda under CNCPF Article 604(III) — the court can order immediate provisional payments before the defendant is even served.

A valid Alimony Court Claim Mexico under CCF Articles 301–323 and CNCPF Article 604 must contain the following essential elements to be admitted and provisional alimony ordered.

Identification of Parties: Full name, CURP, domicilio, RFC (if available), and occupation of the demandante (plaintiff — the beneficiary or their legal representative). Full name, domicilio, RFC, NSS (IMSS social security number), and employer details of the deudor alimentario (defendant/payer). Identifying the defendant's employer is critical for requesting aviso de retención (wage garnishment) under Article 317 CCF.

Filiation and Relationship Basis: Documentary proof of the family relationship creating the alimentary obligation — acta de nacimiento (birth certificate) of minor children naming both parents; acta de matrimonio if the claim is between spouses; judicial filiation order if paternity was established by court rather than voluntary recognition. Without proof of filiation, the court cannot order alimentos.

Beneficiary's Needs (Necesidades del Acreedor): Detailed account of the beneficiary's monthly expenses: food and nutrition (alimentación), housing (renta o hipoteca), utilities, clothing, medical and dental care, education fees (colegiatura, útiles, uniformes), and extracurricular activities. Supported by receipts, school invoices, medical records, and lease agreements. The court will use this as a floor for the pension determination.

Payer's Economic Capacity (Posibilidad del Deudor): Evidence of the defendant's income and assets — recibos de nómina (payroll receipts), IMSS wage report (constancia de semanas cotizadas y salario base), annual ISR declaration filed with the SAT, bank statements, business income documentation, and any other evidence of economic capacity. Under Article 311 CCF, the court may order the defendant to disclose all income sources and the SAT and IMSS to provide income confirmation directly to the court.

Proposed Pension Amount: A specific proposed monthly pensión alimenticia amount or percentage of net income — typically 20–30% for one child, increasing for multiple children, up to 50–60% of net income in some state court guidelines. The proposal should consider the minimum established by SCJN jurisprudencia (Tesis 1a./J. 25/2012) requiring at minimum 30% of net minimum wage per beneficiary.

Request for Alimentos Provisionales: Explicit request for provisional pension under CNCPF Article 604(III) to be ordered with admission of the demanda, pending the final hearing. Supported by evidence of urgent need and basic income documentation.

Request for Aviso de Retención: Where the defendant is an employee, request for court order directed to the employer to deduct the pension from salary at source under Article 317 CCF and remit to the court or directly to the beneficiary. The employer's registered name, address, and RFC should be identified.

Wage Attachment Through IMSS Records: Request for the court to query IMSS employer records (registro patronal) to identify the defendant's current employer if not already known — enabled by IMSS inter-institutional cooperation protocols.

Documentary Exhibits: Actas de nacimiento of beneficiaries; proof of income of both parties; receipts for beneficiary's current expenses; school enrollment certificates; medical records; any previous informal agreements about support; demand letters and communications showing the defendant's refusal to pay.
