Power of Attorney for Vietnam From the US: How the Apostille Works

If you need a representative in Vietnam to act for you, for property, business, or family and legal matters, the signature still has to happen. What changes is who holds the pen. A representative signs on your behalf under a power of attorney. Signed in the United States, that power of attorney is not valid in Vietnam on its own. It has to be notarized here first, and then authenticated.

The authentication is where Vietnam changed. Vietnam's entry into the Hague Apostille Convention took effect for the United States on September 11, 2026. Before that date, a US power of attorney for Vietnam needed the full legalization chain: state certification, authentication by the US Department of State, and a final legalization stamp from a Vietnamese embassy or consulate. That chain is gone. One apostille now finishes the authentication, and the order below is what makes it work.

Step 1: Your lawyer in Vietnam drafts the power of attorney

Start in Vietnam, not here. Your lawyer or representative there knows the wording the receiving office will accept, and specific language naming the property, the transaction, or the company, and the specific representative, holds up better than broad general authority. A US company opening a branch office or a foreign-invested enterprise in Vietnam, for example, files a notarized corporate power of attorney alongside its other documents. Use the exact text your lawyer provided. Do not edit it, and do not sign it before the notary session.

Step 2: Sign it before a US notary

The notary confirms who you are and that you are signing willingly. You sign in front of the notary, never in advance.

You can do this without leaving home. Our partner notaries meet with you online on a secure audio and video signing platform. You need a camera, a valid photo ID, and your own email address, since each signer gets their own link. If a spouse, co-owner, or fellow officer also signs, each of you joins separately, even from different states. Before the session, confirm with your lawyer in Vietnam that remote notarization is acceptable for your file. Most of the lawyers our clients work with accept it, and we confirm with you if there is any doubt.

Step 3: Get the apostille

The apostille comes from the Secretary of State of the state where the notary is commissioned, not the state where you live. That distinction is where these files most often go wrong, because a signer who lives in one state and notarizes in another needs the apostille from the notary's state. A few states add a step before the apostille, where a county clerk or court first verifies the notary's commission. We handle that filing.

Each document needs its own apostille. A power of attorney filed alongside articles of incorporation, a good standing certificate, or board resolutions means a separate apostille for each document, not one for the package.

Step 4: Send the original to Vietnam

We email you and your lawyer a scan of the apostilled document so everyone can confirm it is correct. Then we ship the original by FedEx Priority to your lawyer or representative in Vietnam.

Step 5: Vietnamese translation, after the apostille

Vietnamese authorities still require an official translation into Vietnamese, and it follows the authentication, not the other way around. The apostille certificate itself is part of what the translator renders, so the translator works from the finished package, the document and the apostille together. Translate first and the package has to be redone once the apostille is attached.

What if your power of attorney was already legalized the old way?

Documents legalized before September 11, 2026 under the prior rules generally remain valid. The apostille route applies to documents processed going forward, so a power of attorney that already carries the full embassy chain does not need to be redone just because the rule changed. If you are starting now, start with the apostille.

Mistakes that delay a Vietnam power of attorney

• Signing a generic US form. A standard US power of attorney rarely carries the specific authority a Vietnamese office expects. Use your lawyer's draft.

• Names that do not match. The name on the power of attorney should match your passport exactly.

• Sending the document to the wrong state. The apostille comes from the state where the notarization took place, not the state where you live or where the property sits.

• Translating before the apostille. The translation comes last, after the apostille is attached.

• One apostille for the whole package. A power of attorney and each corporate document filed with it need their own.
