Granting a Procuração (Power of Attorney) in Portugal in 2026 — A Practical Guide to the Notarial Deed, the Documento Particular Autenticado, Special Powers for Property, and Revoking or Using One Abroad

Sooner or later, most foreign residents in Portugal hit a task they cannot do in person: a property deed that has to be signed while you are abroad, a bank that needs a physical signature, a tax matter at the Finanças (tax office) that lands while you are between countries. The Portuguese answer is the procuração — a power of attorney that lets you appoint someone to act legally in your name. It is one of the most useful documents in the system and one of the easiest to get wrong, because the formalities depend entirely on what you are authorising. This guide explains the main routes for 2026, what they cost, and how to cancel or use a procuração abroad.

What a procuração is

A procuração is a written document in which you — the mandante or represented person — grant another person, the procurador or mandatário (attorney or agent), the power to carry out specified acts on your behalf. The person you appoint does not have to be a lawyer; it can be a spouse, a friend, a solicitor or an advogado (lawyer). What matters is that the document states clearly who is being authorised, and to do exactly what. A vague procuração is worse than none, because the bank, notary or registry on the receiving end will simply refuse to act on powers that are not spelled out.

The powers can be broad (poderes gerais, or general powers of administration — paying bills, dealing with utilities, filing routine paperwork) or narrow (poderes especiais, or special powers for a single named act, such as selling one specific flat). For anything significant, narrow and specific is safer.

The formalities: it depends what you are signing

There is no single form. The level of authentication rises with the seriousness of the act:

Everyday and administrative acts. For simple matters, a plain written procuração may be enough, though many public bodies and banks will want your signature formally recognised. That is a reconhecimento de assinatura (signature recognition), a short certification — done by a notary, a lawyer, a solicitador or many Espaços Cidadão (Citizen’s Shops) — confirming the signature is really yours.

Acts that require a public deed. Buying, selling or mortgaging property, and other acts that by law need an escritura pública (public deed) or equivalent, demand a stronger procuração. Here the document must be granted either as an instrumento público drawn up by a notário (notary), or as a documento particular autenticado (DPA, an authenticated private document) prepared and certified by a lawyer, solicitador, notary or chamber of commerce. A DPA carries the same legal weight as a notarial deed for this purpose and is often faster and cheaper. Our guide to notaries and the documento particular autenticado explains the difference in detail.

Legal representation. A procuração forense — the one you sign so an advogado or solicitador can represent you in court or before a public authority — is the exception: granted to a lawyer or solicitor, it does not require signature recognition at all.

Registration, delegation and the irrevocable variant

Some procurações can and should be registered. Portugal runs a Registo de Procurações (register of powers of attorney), and for registered documents you or a third party can pull a certidão permanente (permanent certificate) online through the justice portal to prove the power exists and is still valid. Registration is particularly relevant for property transactions and for the procuração irrevogável (irrevocable power of attorney) — a version granted in the interest of the attorney or a third party, common in property deals, which cannot be freely withdrawn by the grantor.

If you want your attorney to be able to pass powers on — say, from your lawyer to a colleague who can attend a signing — the document must expressly allow substabelecimento (sub-delegation). If it is silent, they cannot delegate.

Signing from abroad

Distance is the whole reason many people need a procuração, so the cross-border routes matter. A power of attorney granted outside Portugal to be used here generally needs to be legalised for Portuguese use — an apostille under the Hague Convention if your country is a member, or consular legalisation if it is not — and accompanied by a certified translation into Portuguese. Our guides to the apostille and consular legalisation and to certified translations set out those steps. A Portuguese procuração that you need to use in another country works the same way in reverse: get it apostilled by the Procuradoria-Geral da República (Attorney General’s Office) before you send it. You can also sign a procuração at a Portuguese consulate abroad, and Portugal now allows certain authentic acts, including some procurações, to be completed by videoconference — a genuine convenience if you cannot travel.

Cost, cancellation and expiry

Costs vary by route: a notarial deed is the dearest option, a documento particular autenticado through a lawyer or solicitor is usually cheaper, and a bare signature recognition costs only a few euros. Always confirm the price and the exact wording the receiving institution wants before you pay — banks and the Finanças can be fussy about phrasing.

Unless it is irrevocable, you can revoke a procuração at any time. To do it cleanly, notify the attorney in writing, tell any third party who has been relying on it (the bank, the buyer, the notary), and, if the document was registered, register the revocation too — otherwise someone could still act on a power you thought you had cancelled. A procuração also lapses when its stated purpose is done, when any end-date passes, and, as a rule, on the death of the grantor.

One last point for newcomers: to appear on any of these documents you will need a Portuguese tax number, and non-residents from outside the EU may also need a tax representative — see our guides to getting a NIF as a non-resident and appointing a representante fiscal. With the tax number in hand and the powers written precisely, a procuração turns most of Portuguese bureaucracy into something you can handle from anywhere in the world.
