If you are an overseas Vietnamese (Viet Kieu) living in Texas and a relative in Vietnam has passed away, you may be entitled to an inheritance, a benefit, or a share of an estate. To claim it, US documents such as a death certificate, birth certificate, or marriage certificate usually have to be authenticated for use in Vietnam and translated into Vietnamese. This page explains how the process works from Texas and what changes in September 2026.
Note that there is no established Vietnamese pension proof-of-life requirement for US residents, so this page focuses on inheritance and estate entitlements rather than ongoing pension confirmation.
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 Vietnam?
The answer depends on timing. The Hague Apostille Convention becomes effective for Vietnam on September 11, 2026. From that date, a document apostilled by the Texas Secretary of State will be accepted in Vietnam without further consular legalization.
Before September 11, 2026, an apostille alone is not enough. Documents must instead go through the traditional consular legalization chain: after Texas certification, the document is authenticated by the US Department of State and then legalized by the Embassy or Consulate of Vietnam. If you are acting now, plan around this date — a document apostilled too early may still need the legalization route until the Convention takes effect.
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.
