Mexican Bank Account After an American Dies

The Immediate Freeze

When a death is registered at the Registro Civil in Mexico, bank accounts held solely in the deceased's name are generally frozen. Access is then handled through the Mexican succession process.

For American retirees living in Mexico who paid rent, utilities, or household staff from a local bank account, this creates a cascade of practical problems. Bills stop getting paid. Automatic debits bounce. And the surviving spouse or family cannot access those funds — even with a U.S.-issued power of attorney, because all powers of attorney terminate at the moment of death under both Mexican and U.S. law.

Joint accounts with a surviving co-owner may be treated differently from accounts held solely by the deceased. The surviving account holder should visit the bank branch in person with the Acta de Defunción and their own identification to clarify what access and documentation the bank requires.

How to Close a Mexican Bank Account from the United States

The short answer: you usually can't do it remotely. Mexican banks require in-person proceedings for estate-related closures, and the process runs through the Mexican legal system, not the U.S. probate system.

Here is the path:

Step 1: Complete the Mexican probate process. If the deceased left a valid Mexican will (testamento) registered with a notary, the designated executor (albacea) petitions the local civil court or a notary public to open the succession proceeding. If there is no Mexican will, the process defaults to sucesión legítima (intestate succession) under the civil code of the state where the account is held. This requires a court-appointed administrator and takes significantly longer.

Step 2: Obtain the court order or notarial resolution. The Mexican court or notary issues a formal resolution identifying the heirs and authorizing the distribution of assets. This resolution is the document the bank needs.

Step 3: Present the resolution to the bank. The designated heir or their Mexican attorney presents the court resolution, the certified Acta de Defunción, and their own identification to the bank. The bank then releases the funds or transfers the balance to the designated beneficiaries.

The timeline for this process ranges from three months (with a will and cooperative heirs) to over a year (without a will, with multiple heirs, or with disputes). A Mexican attorney specializing in estate law is effectively mandatory.

The SAT and INM Administrative Obligations

If the deceased was a Mexican temporary or permanent resident or held an RFC, the applicable Mexican administrative filing should be made within 30 days of the death:

INM residency cancellation. If the deceased held a temporary or permanent residency card, the family must present the Acta de Defunción (with a valid QR code), the original residency card, and the deceased's passport to the nearest Instituto Nacional de Migración delegation. The INM cancels the residency file.

SAT tax registry cancellation. If the deceased had a Mexican taxpayer identification number (RFC), the estate's liquidator must file a cancellation notice with the Servicio de Administración Tributaria. Failing to cancel the RFC creates a zombie tax record — the SAT continues to expect filings and can declare the estate in default, complicating later transfers of Mexican property.

The U.S.-Side IRS Transfer Certificate

Closing accounts in Mexico is only half the picture. On the U.S. side, a non-resident estate with U.S.-situated assets exceeding $60,000 may face an additional transfer-certificate requirement from financial institutions.

For a qualifying estate, the bank or brokerage may require an IRS Transfer Certificate (Form 5173) before releasing the affected funds. This certificate confirms that all federal estate tax liabilities have been assessed. The application goes directly to the IRS, and processing times are measured in months, not weeks.

Families who assume the U.S. probate court's letters of administration will unlock everything discover this requirement the hard way — the court order alone is not sufficient for the bank's compliance department.

Practical Steps to Protect Assets

Families dealing with the death of an American in Mexico should take these financial protection steps in the first two weeks:

1. Photograph all bank cards, account statements, and financial records found among the deceased's belongings in Mexico before anything is moved or discarded
2. Notify U.S. financial institutions in writing using the e-CRODA or apostilled Acta de Defunción — this protects the estate from unauthorized transactions
3. Engage a Mexican attorney to begin the succession proceeding for Mexican-held assets
4. File IRS Form 5173 if the deceased was a non-resident and frozen U.S. assets exceed $60,000
5. If applicable, cancel the deceased's INM residency and SAT tax registry within 30 days
