Document Authentication for Vietnam
By John F. Heinz, Managing Director, Prismark Signature Services
Published: August 7, 2026
Quick Answer
Documents for use in Vietnam currently require special attention. Vietnam has joined the Hague Apostille Convention, but the Convention does not enter into force for Vietnam until September 11, 2026. Until the applicable requirements change, documents may still require authentication and legalization rather than the standard Hague apostille process.
For California documents, preparation may involve authentication through the California Secretary of State followed by additional Vietnamese consular or destination-country requirements. Federal documents may follow a different authentication path. Because Vietnam’s requirements are evolving and can vary by document and intended use, contact Prismark Signature Services for current document-preparation and authentication information before beginning the process.

Common Documents Authenticated for Use in Vietnam
Documents prepared for use in Vietnam may include birth certificates, marriage certificates, death certificates, divorce decrees, court documents, powers of attorney, affidavits, adoption records, diplomas, college transcripts, school records, corporate documents, and criminal background checks.
These documents may be requested for family matters, education, employment, business transactions, property matters, inheritance, or other official purposes. The Vietnamese authority or organization receiving the document determines what is required.
Do I Need a Certified Copy?
For many government-issued records, yes. California birth, marriage, and death records should generally be official certified copies suitable for authentication. Court records generally require official certified court copies.
Educational, corporate, privately signed, and other documents may require different preparation. Prismark can review the document before processing begins and help identify the appropriate preparation path.
California Document or Federal Document?
The authentication path depends on who issued the document. California state and locally issued documents generally begin with the appropriate California authentication stage once properly prepared. Federal documents generally follow the applicable federal authentication process rather than the California Secretary of State process.
Because the current Vietnam process can differ depending on the document and receiving authority, the appropriate next step should be confirmed before processing continues.
Are Additional Steps Required?
They may be. Depending on the document and its intended use, additional legalization or authentication through Vietnamese consular or destination-country authorities may be required after the applicable U.S. authentication stage.
Requirements can change, particularly as Vietnam transitions to the Hague Apostille Convention. Rather than relying on older instructions or a one-size-fits-all process, contact Prismark for current information about the authentication path for your document.
Do My Documents Need to Be Translated?
Some documents used in Vietnam may require a Vietnamese translation, but translation requirements depend on the receiving authority and intended use. Clients should confirm the destination requirements before arranging translation.
If translation is required, Prismark can coordinate professional Vietnamese translation services through our trusted translation partners.
Authentication Does Not Guarantee Acceptance
Authentication verifies the signature, official capacity, and, when applicable, the seal or stamp associated with a public document. It does not determine whether the document satisfies every requirement of the Vietnamese authority receiving it.
The receiving authority may impose separate requirements concerning the document’s form, recency, translation, or intended use.
