When a relative dies in Texas and leaves a bank account in Mexico, or when you need to operate or close a Mexican account from the United States, the Mexican bank will ask for US documents that carry an apostille. A death certificate, proof of relationship, or a power of attorney issued in Texas has no legal weight in Mexico until it is authenticated. This page explains how the apostille works and what a Mexican bank expects.
What an apostille is
An apostille is a certificate that authenticates a public document — a notary's signature, a court seal, a registrar's certification — so it will be accepted by authorities in another country. For countries in the Hague Apostille Convention, the apostille is the finish line. For countries outside it, the same Texas certificate is the first step in a short legalization chain.
Does an apostille work in Mexico?
Yes. Mexico is a member of the Hague Apostille Convention, so a Texas document that carries an apostille from the Texas Secretary of State is accepted directly by Mexican banks, notaries (notarías), and courts. There is no need for consular legalization at a Mexican consulate. One important exception works in your favor: if the deceased was a Mexican national and the death was registered at a Mexican consulate in the US, that consular record has full effect in Mexico without an apostille.
How the Texas Secretary of State apostille works
Texas apostilles come from a single office: the Secretary of State's Authentications Unit in Austin. There is no county-clerk step — a document notarized by any Texas notary, in any of the 254 counties, goes straight to the state. Since October 2023 Texas issues one Universal Apostille (Form 2102) that works for every destination, whether or not the country belongs to the Hague Apostille Convention.
The state fee is $15 per document. Mailed requests can take up to 25 business days; in-person and appointment service in Austin is same-day for up to 10 documents, and a bulk drop-box handles larger batches in 24–48 hours. There is no online submission — every request is handled by mail or in person. Certified copies of vital records (birth, death, marriage, divorce) must be less than five years old.
Federal documents — FBI background checks, USCIS naturalization certificates, IRS letters — cannot be apostilled by Texas; they go to the U.S. Department of State. We confirm the correct authority before anything is filed, so your documents are never rejected on a technicality.
Claiming or closing a Mexican bank account from the US
A Mexican bank freezes a deceased account holder's account as soon as it receives notice of the death. If there is no registered beneficiary and no will, the heirs must establish who inherits through a declaración de herederos (a declaration of heirs, done before a notary or a judge). For accounts above roughly $70,000 MXN, banks such as BBVA Mexico generally require a completed testamentary or intestate succession with a named albacea (estate administrator) before releasing funds. Treat that figure as approximate and confirm the current threshold with the specific bank.
To process the claim, banks typically require:
- An apostilled US death certificate, then translated by a perito traductor (official translator)
- Official photo ID of both the deceased and the claimant
- Proof of the family relationship
The death is also inserted into the Mexican Registro Civil. CONDUSEF, the financial consumer agency, runs a beneficiary-search service that can help locate accounts if you are unsure where the deceased banked. Because the same apostilled death certificate is often needed by the bank, the notaría, and the property registry at the same time, request several apostilled copies up front rather than one.
Documents you'll need
- Apostilled US death certificate (multiple original copies recommended)
- Official ID of the deceased and of each claiming heir
- Proof of relationship (birth or marriage certificates, apostilled)
- A power of attorney to a Mexican representative, if you cannot appear in person (apostilled)
- The declaración de herederos / succession documents once completed in Mexico
Translation
Once your US documents are apostilled, a Mexican perito traductor (court-authorized official translator) must translate them into Spanish. Do the apostille first, then the translation, because the translator usually renders the apostille page as well. Build in time for this step; it is separate from the apostille and can add several days.
We handle the whole apostille — you don't travel to Austin
Our firm provides full-service apostille handling: we prepare your document, coordinate Texas notarization or certified copies, file the Universal Apostille request with the Secretary of State, add U.S. Department of State and embassy legalization when a country requires it, arrange certified translation, and deliver the finished documents to you or your recipient abroad.
We also coordinate directly with your counsel overseas — a barrister or solicitor in Commonwealth countries, an advocate in South Asia, a notario público in Latin America — so the document is drafted with the exact wording their registry, court, or bank requires before anything is apostilled.

A note on accuracy
Apostille and legalization requirements change, and each receiving institution — a foreign land registry, bank, pension office, or consulate — can impose its own rules. This article reflects requirements verified in 2026 and is general information, not legal advice.
