What Is a Financial Services Complaint to CONDUSEF Mexico (Queja CONDUSEF)?

A Financial Services Complaint to CONDUSEF Mexico (Queja CONDUSEF) is a formal written complaint filed by a user of financial services (usuario de servicios financieros) before the Comisión Nacional para la Protección y Defensa de los Usuarios de Servicios Financieros (CONDUSEF) — the federal regulatory body created by the Ley de Protección y Defensa al Usuario de Servicios Financieros (LPDUSEF, published in the Diario Oficial de la Federación on 18 January 1999) — against a financial institution (institución financiera) for conduct that violates the user's contractual rights or applicable financial consumer protection law.

The LPDUSEF Article 50 establishes the substantive right of financial service users to file complaints before CONDUSEF and the procedural framework governing those complaints. CONDUSEF is an autonomous public body (organismo público descentralizado) under the Secretaría de Hacienda y Crédito Público (SHCP) with authority to mediate disputes (conciliación), issue recommendations (recomendaciones), and impose sanctions on financial institutions that include banks (instituciones de crédito) supervised by the Comisión Nacional Bancaria y de Valores (CNBV), insurance companies (instituciones de seguros) regulated by the Comisión Nacional de Seguros y Fianzas (CNSF), pension fund administrators (AFORE) supervised by the Comisión Nacional del Sistema de Ahorro para el Retiro (CONSAR), credit unions (uniones de crédito), microfinance institutions (sociedades de ahorro y préstamo), investment funds (fondos de inversión), and fintech companies (instituciones de tecnología financiera) regulated under the Ley Fintech (DOF 9 March 2018).

The Ley de Instituciones de Crédito Article 50 Bis requires all credit institutions operating in Mexico to maintain a Unidad Especializada de Atención a Usuarios (UNE) — a dedicated consumer affairs unit — to handle first-instance complaints before a user escalates to CONDUSEF. Filing a complaint with the institution's UNE is generally required as a prerequisite before CONDUSEF intervention, though CONDUSEF may accept a complaint directly in urgent circumstances or when the UNE has failed to respond within the statutory timeframe of five business days under Article 50 Ley de Instituciones de Crédito.

Common grounds for CONDUSEF complaints include: unauthorised charges or commissions (cargos o comisiones no autorizadas) on bank accounts or credit cards; denial of insurance claims (rechazo de reclamaciones de seguros) without adequate legal justification under the Ley sobre el Contrato de Seguro; fraudulent use of financial products attributed to identity theft (robo de identidad); incorrect reporting to credit bureaus (buró de crédito — Buró de Crédito, S.A. de C.V. or Círculo de Crédito, S.A. de C.V.); failure to apply payments correctly to mortgage or personal loan balances; abusive collection practices (prácticas de cobranza abusiva) that violate the Circular Única de Bancos; denial of AFORE retirement savings transfers (traspasos de AFORE); and misinformation during the sale of financial products (ventas fraudulentas or misselling).

CONDUSEF operates the REDECO (Red de Unidades Especializadas de CONDUSEF) system for electronic complaint filing and maintains SIPRES (Sistema de Registro de Prestadores de Servicios Financieros) for tracking institutional compliance. The CONDUSEF portal at www.condusef.gob.mx allows users to file complaints electronically, track complaint status, and access the Buró de Entidades Financieras — a public database of financial institutions' complaint and sanction records that enables consumers to compare institutions' service quality records before entering a financial relationship.

When Do You Need a Financial Services Complaint to CONDUSEF Mexico (Queja CONDUSEF)?

A CONDUSEF complaint is needed when a user of financial services in Mexico has been harmed by the conduct of a regulated financial institution and either the institution's internal Unidad Especializada de Atención a Usuarios (UNE) has failed to resolve the dispute within five business days under Article 50 Ley de Instituciones de Crédito, or the UNE's response was inadequate or denied the claim without proper justification.

The complaint form is needed when a bank (BBVA México, Citibanamex, Banorte, HSBC México, Santander México, Scotiabank México, or any CNBV-supervised institution) makes unauthorised charges to a checking account (cuenta de cheques), savings account (cuenta de ahorro), or credit card (tarjeta de crédito) — including ATM fraud, card cloning (clonación de tarjeta), and unauthorised digital transactions.

A CONDUSEF complaint is required when an insurance company (Metlife México, GNP Seguros, AXA México, Qualitas, MAPFRE, or any CNSF-supervised insurer) denies a valid insurance claim — including auto insurance claims, life insurance death benefits, health insurance medical reimbursements, and home insurance claims — without providing a legally adequate written justification under the Ley sobre el Contrato de Seguro.

The form is needed when an AFORE (Banamex AFORE, XXI Banorte, SURA, Coppel, or any CONSAR-supervised administrator) incorrectly manages a worker's retirement savings account under the Sistema de Ahorro para el Retiro (SAR), denies a transfer request (traspaso), or fails to correctly apply employer and employee contributions under the Ley del Seguro Social.

A CONDUSEF complaint is appropriate when a fintech company (institución de tecnología financiera) regulated under the Ley Fintech or a SOFOM (Sociedad Financiera de Objeto Múltiple) charges improper commissions, fails to disclose costs in the CAT (Costo Anual Total), or applies collection practices that violate CONDUSEF circulares.

Under LPDUSEF art. 50, users must file a CONDUSEF complaint within two years of the event giving rise to the complaint — delay beyond this prescription period may bar the complaint. Filing promptly preserves the user's legal rights and initiates the conciliation process that may result in recovery of the disputed amount without litigation.

Credit bureau disputes (aclaraciones al buró de crédito) involving incorrect negative records reported by banks, credit card issuers, or SOFOM lenders to Buró de Crédito or Círculo de Crédito also require a CONDUSEF complaint when the reporting institution refuses to correct inaccurate information — CONDUSEF coordinates with the Comisión Nacional Bancaria y de Valores (CNBV) to compel corrections under the Ley para Regular las Sociedades de Información Crediticia.

What to Include in Your Financial Services Complaint to CONDUSEF Mexico (Queja CONDUSEF)

A valid CONDUSEF complaint under the Ley de Protección y Defensa al Usuario de Servicios Financieros (LPDUSEF) must contain the following essential elements to be accepted and processed by CONDUSEF:

User Identification: Full legal name, CURP (Clave Única de Registro de Población), RFC (if applicable), official identity document number (INE/IFE credential, passport, or resident card), address, telephone number, and email address of the complainant (quejoso). CONDUSEF requires verified identity to prevent fraudulent complaints and to communicate resolutions.

Financial Institution Identification: Full registered name of the financial institution (denominación social), the specific branch or office (sucursal u oficina) where the relationship or incident occurred, the account or policy number (número de cuenta, póliza, o contrato), and the product type (crédito hipotecario, tarjeta de crédito, seguro de auto, AFORE, etc.).

Description of the Complaint: A clear, chronological account of the events giving rise to the complaint — including dates, amounts, transaction references, names of employees involved, and the specific conduct of the financial institution that violated the user's rights under the applicable law (LPDUSEF, Ley de Instituciones de Crédito, Ley sobre el Contrato de Seguro, Ley del SAR, or Ley Fintech).

Evidence Documentation: Copies of all supporting documents — account statements (estados de cuenta), contract or policy terms (contrato o póliza), correspondence with the institution (cartas, correos electrónicos), UNE complaint reference number (número de folio UNE), and any receipts or transaction records (comprobantes de transacción) evidencing the disputed conduct.

Amount in Dispute: The specific monetary amount (monto reclamado) in Mexican pesos (MXN) that the user seeks to recover — CONDUSEF conciliation procedures are available for disputes up to the applicable limit established by CONDUSEF's internal regulations; disputes exceeding certain amounts may be referred to arbitration (arbitraje CONDUSEF) under LPDUSEF Article 68.

Prior UNE Contact: Record of the complaint filed with the financial institution's UNE — including the UNE folio number, date of filing, and the institution's response (or lack thereof). This establishes that the mandatory first-instance process was followed before escalating to CONDUSEF.

Relief Requested: A specific statement of the remedy sought — reversal of unauthorised charges, payment of a denied insurance claim, correction of credit bureau reporting, or other specific corrective action. CONDUSEF's conciliation process aims to reach a binding convenio conciliatorio between the parties.

Convenio Conciliatorio Reference (for Follow-up Complaints): If a previous CONDUSEF conciliation agreement (convenio conciliatorio) was reached but the financial institution failed to comply with its terms, the complaint must include the folio number and date of the prior convenio — non-compliance with a binding CONDUSEF convenio is a separate infraction subject to sanctions under LPDUSEF Article 94 and entitles the user to request immediate enforcement through CONDUSEF.

Buró de Entidades Financieras Reference: Users may attach a printout from CONDUSEF's Buró de Entidades Financieras (buro.gob.mx) showing the financial institution's historical complaint rates, unresolved complaint percentage (índice de reclamaciones no resueltas), and prior CONDUSEF sanctions — this contextual evidence demonstrates a pattern of conduct and may support a request for referral to the CNBV, CNSF, or CONSAR for supervisory action beyond individual conciliation.
