If you live in Texas and receive an IMSS or ISSSTE pension from Mexico, you must periodically prove you are still alive to keep the payments flowing. If a Mexican relative has passed away and you are entitled to a survivor's or inheritance pension, you will need to send a US death certificate to Mexico in a form the institution will accept. In both situations, a Texas document usually has to be apostilled before it will carry any legal weight south of the border.
This page explains when an apostille is required, how the Texas process works, and what Mexico specifically expects for proof-of-life and survivor-pension claims.
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. A single apostille issued by the Texas Secretary of State is accepted throughout Mexico, so there is no need for further legalization by a Mexican consulate for the document itself. The apostille certifies that the Texas notary or official who signed your document is genuine; a Mexican institution or the Registro Civil will then accept it as authentic.
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.
How Mexico's proof-of-life and survivor-pension process works
IMSS and ISSSTE pensioners living abroad must prove survival every six months. The standard route is to appear in person at a Mexican consulate by appointment. The service is free: the consulate certifies that you are alive and transmits the confirmation directly to the institution. If you miss the window, payments can be held until you comply.
IMSS also offers a biometric registration option through the IMSS Digital app, which can let some pensioners confirm survival without a consular visit. Because these routes are handled directly by the consulate or the app, an apostilled life certificate is generally not the primary path for ongoing proof of life. It becomes useful when an institution asks for a notarized survival or status document, or when a relative is acting on your behalf.
Two important points for entitlements:
- The Pensión del Bienestar is different: it is lost when the beneficiary moves abroad, unlike an IMSS or ISSSTE pension, which continues.
- For a survivor or inheritance pension, a US death certificate must be apostilled and translated by a perito traductor (official court-authorized translator). The death is also registered with the Mexican Registro Civil. A relative in Mexico can act on your behalf under an apostilled poder (power of attorney) or one executed at a consulate.
Documents you'll need
- Your US-issued life or survival certificate, notarized in Texas (when an institution requests one), apostilled by the Texas Secretary of State
- For survivor claims: the US death certificate, apostilled, plus certified translation
- A power of attorney (poder), apostilled, if a relative will act for you in Mexico
- Your Mexican pension or affiliation number (IMSS/ISSSTE) and identification
- Certified Spanish translations by a perito traductor where required
Translation
Mexican institutions and the Registro Civil require documents to be in Spanish. Translations must be done by a perito traductor (an officially authorized translator), not just any bilingual person. Arrange the translation after the apostille is attached, so the apostille itself can be translated along with the document. Building in time for translation avoids missing a six-month survival deadline.
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.
