If you live in Texas and need to sell, transfer, or mortgage property in Vietnam, you will likely need a power of attorney so someone in Vietnam can act for you. Vietnam is in the middle of an important transition. It has acceded to the Hague Apostille Convention, but the apostille only becomes usable there on September 11, 2026. Until that date, a Texas document still requires the older, longer consular legalization chain. Which path applies to you depends on your timing.
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?
Not yet, but soon. Vietnam has acceded to the Hague Apostille Convention, and an apostille will be accepted there starting September 11, 2026. Before that date, a Texas power of attorney must go through full consular legalization, not an apostille.
Before September 11, 2026 (legalization chain):
- Notarize the power of attorney before a Texas notary.
- Obtain a U.S. Department of State authentication certificate.
- Legalize the document at a Vietnamese embassy or consulate.
- In Vietnam, translate it into Vietnamese and have the translation notarized there.
On or after September 11, 2026: a single apostille from the Texas Secretary of State replaces the Department of State and consular legalization steps. You will still need a Vietnamese translation.
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.
What Vietnam requires for a property POA
Make the power of attorney specific. It should authorize the exact acts your agent will perform, such as to sell, sign the transfer documents, receive payment, and pay the applicable taxes, and it should identify the property or asset involved. A vague general power invites problems at the local office.
There is an important limitation to know about the legalization route: Vietnamese diplomatic missions may decline to notarize powers of attorney for the purchase, sale, transfer, or mortgage of real estate. They can typically handle inheritance-related powers of attorney. If your transaction is a straight sale or purchase, do not assume the consulate will process it, and plan to have the POA executed and authenticated in the United States and then legalized (or apostilled, after September 2026) for use in Vietnam.
Documents you'll need
- A specific power of attorney identifying the property and the acts authorized
- The grantor's passport
- The full legalization chain, or the apostille if on or after September 11, 2026
- A Vietnamese translation, notarized in Vietnam
- Property and title details for the Vietnamese notary or authority
Translation
Vietnam requires the document to be translated into Vietnamese, and the translation is notarized in Vietnam rather than in Texas. This holds true both before and after the September 2026 apostille date. Because the translation and notarization happen in-country, coordinate with your agent or a Vietnamese notary so the document is ready when it arrives.

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.
