Life Insurance Beneficiary Change Mexico (Designación de Beneficiario)

A Life Insurance Beneficiary Change Mexico (Designación o Cambio de Beneficiario de Seguro de Vida) is a written instruction submitted by the policyholder (contratante) or insured (asegurado) to their Mexican life insurance company to designate new beneficiaries (beneficiarios) or to modify the identity, percentage allocation, or priority order of existing beneficiaries under a life insurance policy (póliza de seguro de vida). In Mexico, life insurance beneficiary designations are governed primarily by the Ley sobre el Contrato de Seguro (LSCS), published in the Diario Oficial de la Federación on 31 August 1935 and continuously reformed, with Article 157 LSCS establishing the insured's right to freely designate, modify, or revoke the beneficiary designation at any time during the life of the policy without the consent of previously named beneficiaries.

The Ley sobre el Contrato de Seguro Article 157 provides the foundational rule that the insured may designate one or more beneficiaries and reserve the right to revoke or modify the designation at any time — unless the designation has been made irrevocably (irrevocablemente) with the express written consent of the insured, in which case modification requires the written agreement of the irrevocable beneficiary. Article 158 LSCS establishes that a beneficiary designation that does not specify percentage allocations among multiple beneficiaries is presumed to be in equal parts (partes iguales). Article 159 LSCS addresses the sequence of contingent beneficiaries (beneficiarios contingentes) — if the primary beneficiary predeceases the insured without a contingent beneficiary being named, the insurance benefit (suma asegurada) passes to the insured's estate (masa hereditaria).

The Comisión Nacional de Seguros y Fianzas (CNSF), established under the Ley de Instituciones de Seguros y de Fianzas (LISF) published in the DOF on 4 April 2013, is the federal regulatory body supervising all insurance companies (instituciones de seguros) operating in Mexico. CNSF Circular Única de Seguros y Fianzas (CUSF), issued under Article 202 LISF, requires insurers to maintain updated beneficiary designation records and to process beneficiary change requests within defined timeframes. CNSF-authorised insurers include Metlife México, S.A., GNP (Grupo Nacional Provincial), AXA Seguros, S.A. de C.V., BBVA Seguros, S.A. de C.V., and Seguros SURA México, S.A. de C.V., among others.

The Ley de Instituciones de Seguros y de Fianzas Article 202 requires that all beneficiary designations be recorded in the insurer's policy registry and that the insurer notify the policyholder in writing of any confirmed change. For group life insurance policies (seguros de vida colectivos) issued under employment contracts governed by the Ley Federal del Trabajo (LFT), beneficiary designations often follow the employer's standard form, but the employee retains the right under LSCS Article 157 to modify the beneficiary independently of the employer's group policy terms.

From an estate planning perspective, a life insurance beneficiary designation in Mexico operates outside the insured's estate for succession purposes — the suma asegurada paid to a named beneficiary is not subject to the intestate succession rules of the Código Civil Federal (CCF) Articles 1599 through 1749 governing intestate inheritance (sucesión intestamentaria), nor to the probate process (juicio sucesorio) administered by the Juzgados Civiles. However, if no beneficiary is named or all named beneficiaries predecease the insured, the policy benefit reverts to the estate and becomes subject to CCF succession rules and the corresponding Impuesto Sobre la Renta (ISR) treatment under Articles 93 Fraction XXI of the Ley del Impuesto sobre la Renta (LISR), which exempts life insurance proceeds paid to beneficiaries from ISR.

The Servicio de Administración Tributaria (SAT) administers the tax exemption for life insurance proceeds under LISR Article 93 Fraction XXI — benefits paid to named beneficiaries upon the insured's death are exempt from ISR regardless of the amount, while benefits paid to the insured's estate may be subject to estate duty considerations under the CCF and applicable state inheritance tax rules in jurisdictions such as Tamaulipas, Nuevo León, and Chihuahua that historically maintained inheritance taxes.

A Life Insurance Beneficiary Change Mexico is required whenever the policyholder or insured wishes to modify the beneficiary designation on an existing life insurance policy — whether due to changes in marital status, birth of children, death of a named beneficiary, divorce, or strategic estate planning decisions — in compliance with Ley sobre el Contrato de Seguro Article 157.

The beneficiary change form is needed when a policyholder marries or divorces. Under the Código Civil Federal and applicable state civil codes, marriage (matrimonio) and divorce (divorcio) do not automatically update insurance beneficiary designations in Mexico — unlike some US jurisdictions. A policyholder who divorces without updating their beneficiary designation risks having the ex-spouse (cónyuge divorciado) receive the policy benefit, since LSCS Article 157 requires an affirmative act to revoke or change the designation.

The document is required when a new child is born or adopted. Under the Ley General de los Derechos de Niñas, Niños y Adolescentes (LGDNNA) and the principle of interés superior del menor, parents with life insurance policies should update beneficiary designations to include minor children (menores de edad), designating a legal guardian (tutor) or trust (fideicomiso) to receive and administer the suma asegurada on their behalf until they reach the age of majority (18 years under CCF Article 647).

The form is needed when a previously named beneficiary dies. If the named beneficiary (beneficiario primario) predeceases the insured without a contingent beneficiary (beneficiario contingente) being designated, LSCS Article 159 provides that the policy benefit passes to the insured's estate — subjecting it to the probate process and potentially exposing it to the insured's creditors under CCF succession rules. Prompt redesignation prevents this outcome.

A beneficiary change is needed in estate planning contexts where the policyholder wishes to align their insurance coverage with a testamentary succession plan (testamento notarial) or a trust structure (fideicomiso de administración). Coordinating the insurance beneficiary designation with the succession plan confirms that the overall estate distribution reflects the policyholder's intentions without conflict between the will and the policy payout.

Under LSCS art. 157, LISF art. 202, and CNSF Circular Única de Seguros y Fianzas, Mexican policyholders should review and update beneficiary designations whenever significant life events occur — keeping the designation current avoids costly disputes between competing claimants and delays in the insurer's claims processing.

A valid Life Insurance Beneficiary Change Mexico under the Ley sobre el Contrato de Seguro and the Ley de Instituciones de Seguros y de Fianzas must contain the following elements to be recognised by the insurer and effective under Mexican law:

Policy and Insurer Identification: Full name of the insurance company (institución de seguros) authorised by the Comisión Nacional de Seguros y Fianzas (CNSF), the policy number (número de póliza), the type of insurance (seguro de vida individual / seguro de vida colectivo), the policy start date (fecha de inicio de vigencia), and the face amount (suma asegurada) if known. Accurate policy identification is required by LISF Article 202 for the insurer to locate and update the correct policy record.

Policyholder and Insured Identification: Full legal name (nombre completo), RFC (Registro Federal de Contribuyentes), CURP (Clave Única de Registro de Población), official identity document number (Credencial del INE, pasaporte, or cédula profesional), date of birth, and domicile of the policyholder (contratante) and insured (asegurado) — who may or may not be the same person. The RFC and CURP are required by SAT regulations for the insurer's fiscal reporting under the LISR tax exemption framework.

Beneficiary Designation with Full Identification: For each beneficiary: full legal name, CURP, RFC if available, relationship to the insured (parentesco — cónyuge, hijo, padre, hermano, or no familiar), date of birth, official address, and the percentage of the suma asegurada allocated to each (porcentaje de participación). The sum of all beneficiary percentages must equal 100%. For minor beneficiaries, the legal guardian's information must be provided alongside the minor's details.

Beneficiary Priority Structure: Specification of whether each beneficiary is a primary beneficiary (beneficiario primario) or contingent beneficiary (beneficiario contingente or subsidiario). Contingent beneficiaries receive the policy benefit only if all primary beneficiaries predecease the insured or are otherwise unable to receive the benefit. Under LSCS Article 158, failure to specify priority is presumed equal sharing among named beneficiaries.

Type of Designation — Revocable vs. Irrevocable: Confirmation of whether the designation is revocable (the default under LSCS Article 157, permitting future modification without beneficiary consent) or irrevocable (irrevocable, requiring the named beneficiary's written consent for any future modification). Irrevocable designations are common in divorce settlement agreements (convenios de divorcio) and credit insurance (seguro de crédito) arrangements.

Revocation of Prior Designations: An explicit statement revoking all prior beneficiary designations in force on the policy, so that the current designation replaces all previous ones without ambiguity. Under CNSF Circular Única de Seguros y Fianzas, the insurer must confirm in writing that the prior designation has been cancelled and the new one recorded.

Signature and Authentication: The policyholder's or insured's original signature (firma autógrafa), date, and — for policies with a suma asegurada above $5,000,000 MXN — a notarised signature (firma ante notario público) may be required by the insurer under its internal procedures. The insurer's acknowledgment stamp or written confirmation of receipt and processing completes the document.
