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

If you are buying property in Portugal and cannot be at the signing, the escritura still has to be signed. What changes is who holds the pen. Many American purchases close without the buyer present, through a power of attorney, a procuração, granted to a Portuguese lawyer or trusted representative. Signed in the United States, that power of attorney is not valid in Portugal on its own. It has to be notarized here first, and then apostilled.

Portugal is a member of the Hague Apostille Convention, and the Convention has been in force between Portugal and the United States since 1969. That is the good news in this file: one apostille finishes the authentication. Portuguese law requires a power of attorney used for a property transaction to be authenticated by a notary or a Portuguese consulate, and the apostille satisfies that requirement for a US-signed document. The order below is what makes it work.

Step 1: Your Portuguese lawyer drafts the procuração

Start in Portugal, not here. Your lawyer there knows the wording the notary will accept, and specific language naming the property and the acts authorized holds up better than broad general authority. A general power of attorney can hand over sweeping authority, financial management, contract signing, opening a bank account, which is more than most buyers need for a single purchase. Use the exact text your Portuguese lawyer provided. Do not edit it, and do not sign it before the notary session.

A procuração does more than closings. The same kind of document authorizes a Portuguese lawyer to act for you in other matters, and buyers commonly have related paperwork running alongside the purchase, including the Portuguese tax number the transaction requires. Confirm with your lawyer exactly which acts your procuração needs to cover before anything is signed here.

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 or co-owner also signs, each of you joins separately, even from different states. Before the session, confirm with your Portuguese lawyer 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.

Watch the notarial certificate itself. On powers of attorney for Portugal, that certificate is where these documents most often fail authentication: a missing commission expiration, an unsigned certificate, or the wrong certificate for the act performed stops the apostille before anyone in Portugal reads the document.

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 plus a separate corporate or estate document means two apostilles, not one.

Step 4: Send the original to Portugal

We email you and your Portuguese 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 Portugal.

Step 5: Portuguese translation, after the apostille

After authentication, the package is translated into Portuguese. Order matters here: the apostille certificate itself is part of what gets translated. Portuguese authorities require translation of your documents. Translate first and you pay twice, once for the document and again once the authentication is attached.

Mistakes that delay a Portugal power of attorney

• Signing a generic US form. A standard US power of attorney rarely carries the specific authority a Portuguese notary expects. Use your Portuguese 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 two documents. A power of attorney and a separate document each need their own.
