Vietnam is now part of the Hague Apostille Convention. Since 11 September 2026, a California document headed to Vietnam needs one apostille from the Secretary of State — no authentication certificate, no trip to the Vietnamese Embassy in Washington, D.C.
The Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents entered into force for the Socialist Republic of Viet Nam on 11 September 2026. California documents bound for Vietnam now travel on the apostille route.
Orange County sends more documents to Vietnam than almost anywhere else in the country. Little Saigon — Westminster, Garden Grove, Fountain Valley — is home to the largest Vietnamese community outside Vietnam, and the paperwork that follows is constant: property transfers in Ho Chi Minh City, inheritance claims, marriage registration, family sponsorship, power of attorney for a relative handling a sale in Da Nang.
Until last Friday, every one of those documents took the long road. A Westminster resident signing a power of attorney had to get it notarized, send it to Sacramento for a state authentication certificate, then mail it across the country to the Embassy of Vietnam in Washington, D.C. for a legalization stamp — weeks of transit for a document that never needed to leave California.
That middle-and-final leg is gone. One apostille from the California Secretary of State now does the whole job.
Before 11 September 2026
- Notarization or certified copy
- County clerk verification, if required
- California Secretary of State authentication certificate
- Embassy of Vietnam legalization, Washington, D.C.
Now
- Notarization or certified copy
- County clerk verification, if required
- California Secretary of State apostille
The California detail that trips people up: apostille vs. certification
California issues two different certificates, and which one you get depends entirely on the destination country you write on your cover sheet. For Hague member countries the Secretary of State issues an apostille. For non-Hague countries it issues an authentication certificate — a different document that explicitly states it is for use in a non-Convention country and that must be followed by embassy legalization.
Vietnam sat in the second category for decades. As of 11 September 2026 it is in the first. Practically, that means if you fill out the Secretary of State cover sheet today and write "Vietnam" in the destination field, you will receive an apostille — and that apostille is the finished product. Nothing further is required.
If you are holding an authentication certificate for Vietnam
An authentication certificate issued before the change is not an apostille and is not interchangeable with one. If it was already legalized at the Embassy of Vietnam, it remains valid and you do not need to redo anything. If it has not yet been to the embassy, you will likely need a new apostille rather than continuing down the legalization path. Bring it in and we will tell you which position you are in before you spend money on the wrong step.
What happened, and when
Joining the Convention is not a single event. A country deposits its instrument of accession with the depositary — the Ministry of Foreign Affairs of the Netherlands — and a six-month window then opens in which existing member countries may object. Only after that window closes does the treaty actually take effect.
- 31 December 2025 Vietnam deposits its instrument of accession with the Netherlands Ministry of Foreign Affairs.
- January 2026 The Hague Conference on Private International Law notifies the other Contracting Parties, opening the six-month objection period under Article 12(2).
- February 2026 Vietnam's government approves a national implementation plan, directing ministries to have procedures and online submission ready before the effective date.
- May – July 2026 Germany, Austria and Czechia each file objections.
- July 2026 Vietnam issues the implementing decree governing how apostilles are issued and how foreign apostilles are accepted.
- 11 September 2026 The Convention enters into force for Vietnam.
That gap between joining and taking effect caused real confusion through 2026. Documents filed in Vietnam before 11 September still needed the old chain, and an apostille submitted early would have been rejected. Anyone who read a headline in January and switched to apostilles then would have had documents bounced. The transition is now behind us.
Which office issues your apostille
This is where most rejected submissions originate, and it is not a Vietnam question — it is a jurisdiction question that has not changed.
| Your document | Who issues the apostille |
|---|---|
| California birth, death or marriage certificate; California court records; corporate filings; diplomas; anything notarized by a California notary | California Secretary of State — see our Secretary of State apostille service |
| FBI Identity History Summary, Certificate of Naturalization, IRS records, Social Security letters, DD-214, other federal agency records | U.S. Department of State, Office of Authentications in Washington, D.C. |
| Consular Report of Birth Abroad; Consular Reports of Death and Marriage | U.S. Department of State, Passport Services — Vital Records Section |
| Documents issued by a U.S. federal court | The clerk of that federal court |
| A document issued in another state | That state's Secretary of State — California cannot apostille it |
The California Secretary of State authenticates signatures of California notaries and California public officials. It has no authority over a federal record, and no authority over an Arizona birth certificate. Sending a document to the wrong office costs weeks.
Documents Orange County sends to Vietnam most often
- Powers of attorney — by far the most common, usually for a relative selling or managing property in Vietnam
- Birth certificates and marriage certificates for family registration and sponsorship
- Single status affidavits for marriage registration in Vietnam
- Diplomas and transcripts for work permits and teaching positions
- Corporate documents for company registration and investment filings
- Court records, including divorce decrees, for remarriage and inheritance matters
Three countries where nothing changed
Article 12(2) objections
Germany (20 May 2026), Austria (19 June 2026) and Czechia (2 July 2026) each objected to Vietnam's accession. The Convention has not entered into force between Vietnam and those three countries, so documents moving between them still require consular legalization.
This does not affect California documents. The United States has been a party since 1981 and raised no objection, so the U.S.–Vietnam apostille route is fully open.
The reason this matters beyond Vietnam is that Convention membership works bilaterally. An apostille is valid between two countries only where the treaty is in force between that specific pair. A country can appear on the member list while the apostille route is closed for your particular pairing. Several widely circulated summaries of Vietnam's accession list only two objecting countries rather than three, because Czechia filed last. Always check the pairing, not just the list — and for destinations still outside the Convention, see our non-Hague country legalization service.
Vietnamese documents coming to California
The change runs both ways. A Vietnamese birth certificate, household registration extract, marriage certificate, degree or court judgment can now be apostilled in Vietnam and used in California without any step at a U.S. consulate. Vietnam has designated its Ministry of Foreign Affairs as the competent authority, working through the Consular Department in Hanoi and the foreign affairs department in Ho Chi Minh City, with provision for provincial delegation.
For Orange County families, this is the practical half of the change: relatives in Vietnam can now get documents certified locally and send them straight here. A certified Vietnamese-to-English translation is still typically required for use with California courts, county offices and USCIS.
What an apostille does not do
It certifies origin, not content
An apostille verifies the signature, the capacity of the signer, and the seal. It says nothing about whether the content is accurate, whether the document is recent enough, or whether it meets a particular agency's requirements. A Vietnamese authority can still reject an apostilled document for being stale, incomplete or untranslated.
Three things follow. Translation requirements are unchanged — Vietnamese receiving offices generally still require a Vietnamese translation, often a certified or notarized one. Documents already legalized remain valid — nothing carrying an Embassy of Vietnam stamp needs redoing. And expect some friction during the transition, since district and provincial offices in Vietnam processed legalized documents for decades and staff are still adjusting. Build extra lead time into any deadline this autumn.

Key takeaways
- The Apostille Convention took effect for Vietnam on 11 September 2026.
- California documents for Vietnam now need one apostille from the California Secretary of State — no authentication certificate, no Embassy of Vietnam step.
- Federal records still go to the U.S. Department of State, not Sacramento.
- Germany, Austria and Czechia objected, so the apostille route does not apply between Vietnam and those three countries. This does not affect U.S. documents.
- Translation requirements, validity windows and agency-specific rules are unchanged.
- Documents already legalized under the old process remain valid.
Frequently asked questions
Vietnam's status
Is Vietnam now part of the Hague Apostille Convention?
Yes. Vietnam deposited its instrument of accession on 31 December 2025, and the Convention entered into force for Vietnam on 11 September 2026. You can confirm this on the HCCH status table, which lists Viet Nam with that effective date.
Do I still need Embassy of Vietnam legalization for a California document?
No. For documents processed on or after 11 September 2026, an apostille from the California Secretary of State is the complete certification. The Washington, D.C. embassy step is no longer part of the process.
Why did Germany, Austria and Czechia object?
Article 12(2) of the Convention lets any existing member object to a new country's accession within six months, and no reason need be stated. The effect is that the treaty does not enter into force between Vietnam and that country. Objections can be withdrawn later. None of this affects U.S. or California documents.
Does this change visa or entry requirements for Vietnam?
No. The Convention governs how public documents are authenticated, not immigration admission. Tourist entry, e-visas and passport rules are unaffected. What changes is the paperwork behind filings such as property transfers, marriage registration, work permits and company formation.
California specifics
My document has a "certification," not an "apostille." Is it still good?
It depends on how far you got. California issues an authentication certificate for non-Hague destinations and an apostille for Convention countries — they are different documents. If your certificate was already legalized at the Embassy of Vietnam, it remains valid and needs nothing further. If it was not, you will likely need a new apostille. Contact us before paying for another embassy step you no longer need.
Who apostilles a California birth certificate for Vietnam?
The California Secretary of State. You need a certified copy issued by the county recorder or the California Department of Public Health — not a photocopy and not the hospital souvenir certificate. See our birth certificate apostille page.
What about an FBI background check for a Vietnam work permit?
That one does not go to Sacramento. An FBI Identity History Summary is a federal record, so it is apostilled by the U.S. Department of State Office of Authentications in Washington, D.C. No state Secretary of State has jurisdiction over it.
What does the California Secretary of State charge?
The state fee is $20 per apostille, with an additional special handling fee per public official signature for in-person submissions. Fees and current amounts are published on the Request an Apostille page. These are state fees only and are separate from any service fee.
Can I get a same-day apostille in California?
Same-day service is available in person at the Secretary of State's Sacramento and Los Angeles offices, and at the office's periodic pop-up events. Mail requests are processed only in Sacramento and cannot be pulled forward for expedited handling, so if you are working to a deadline, in-person is the route. Check current processing times before planning around either.
Does my notarized power of attorney need the county clerk first?
Usually not for a standard California notarization — the Secretary of State verifies notary signatures directly. County clerk verification comes into play for documents signed by certain county officials, such as a county health officer. Because the answer varies by document and county, it is worth confirming before you mail anything to Sacramento.
Can I apostille a photocopy?
No. California requires an original notarized document or a certified copy issued by the appropriate official. The Secretary of State states plainly that a photocopy is not acceptable, and submissions that include one are returned.
My document was issued in another state. Can you still help?
Yes, but the apostille has to come from the issuing state's Secretary of State — California has no authority over another state's records. We handle out-of-state submissions on your behalf; see our mail-in requests page.
Practical requirements
Do I still need a Vietnamese translation?
In most cases, yes. An apostille certifies the signature and seal, not the language or the content. Vietnamese receiving authorities generally require a Vietnamese translation, frequently a certified or notarized one. We provide certified translation alongside the apostille.
Does the translation get apostilled too, or just the original?
It depends on the receiving authority. Some want the apostille on the original with a translation attached; others accept a translator's certification that is itself notarized and apostilled. Ask the office in Vietnam that will receive the document before you start, because redoing this step is slow and entirely avoidable.
Does an apostille expire?
The apostille itself carries no expiry date. The underlying document is what ages out — many Vietnamese authorities accept a background check, police certificate or single status affidavit only if issued within a recent window, often three to six months. Work backwards from the receiving office's validity rule when scheduling.
How long does the whole process take now?
Removing the embassy step takes weeks out of the timeline — that leg alone often ran three to six weeks including transit to and from Washington, D.C. What remains is the notarization or certified copy, then the Secretary of State apostille, which can be same-day in person or several business days by mail depending on current volume. Check the Secretary of State's published processing times for the current position.
How do I check a country's status myself?
Use the HCCH status table and confirm three things: that the origin country is a member, that the destination country is a member, and that neither has objected to the other. A country can appear on the member list while the apostille route is closed for your specific pairing.
