Buying from abroad: how a power of attorney works in Portugal

You do not need to fly in for every signature. A narrow, properly drafted procuração lets your independent lawyer obtain the NIF, sign the CPCV and complete the deed while you stay where you live.

Filed under: Buying in Portugal

Distance is an inconvenience in a Portuguese purchase. It does not have to be a barrier. The formal signatures can be given by someone acting for you, provided the authority is written down properly before it is needed.

That document is a procuração, a power of attorney. Used well, it keeps a purchase moving across time zones. Used casually, it can hand a stranger far more control than you intended. The difference is in the drafting.

What a procuração actually does

A procuração names the person who may act for you and the acts they may perform. Portuguese law treats it as a voluntary grant of representative powers, and the form of the document follows the form required for the act itself. For a property purchase, that means a formal document, made by public instrument or in another properly authenticated form, not a signed note saying someone may "help with the house".

The notary, bank and tax office will read the words closely. Your representative can do what the document permits. They cannot safely be assumed to have powers it leaves out.

What it can cover

The NIF

Your legal representative can request your Portuguese tax number through the tax authority's e-balcão, using your passport, proof of your address abroad and a power covering that request. The legal representative for this application is a separate role from a tax representative, so do not treat the two labels as interchangeable.

The bank account and mortgage

The power can authorise your representative to open an account and sign loan and mortgage documents. Each bank and lender has its own onboarding checks and preferred wording, so this only works smoothly if they approve the draft before you sign it.

The reservation and CPCV

Your representative can sign the reservation paperwork and the promissory contract within the property, price and conditions you have authorised. This is where a clear limit matters, because the CPCV is binding and its deposit has real consequences.

Taxes, deed and registration

The power can cover paying the purchase taxes, signing the escritura, dealing with registration and receiving the completion documents. If you also want help with utilities, condominium notices or tax correspondence afterwards, say so expressly rather than assuming completion powers stretch that far.

Give it to your lawyer, not to the other side

For most overseas buyers, the sensible holder is their own independent Portuguese lawyer: the person already checking title, reviewing the CPCV and protecting the buyer's side of the transaction. Do not give a broad power to the seller, the selling agent or anyone whose job is to complete the sale for the other side.

My role is different. I view and test the property, work through the price evidence, keep the shortlist honest and make sure what was found on the ground reaches the contract. Your lawyer handles the legal authority and the signatures. Keeping those roles separate is not bureaucracy. It is the safeguard.

The safest power is a narrow one

A good purchase power should answer its own questions before a notary has to ask them:

Do not authorise your representative to transact with themselves unless there is a deliberate reason to do so. Portuguese law treats self-dealing as a conflict risk, and a purchase power does not need that extra complication.

If you have not yet found the property, a power can be drafted around a maximum price and a defined search. It should still be narrow. "Any property, at any price, on any terms" is not convenience. It is exposure.

Three ways to sign one

In Portugal. If you are here on a viewing trip, this is usually the simplest moment to execute the document before a notary or another professional authorised to authenticate it. Do it before the diary fills with contract deadlines.

At a Portuguese consulate. Take a complete draft prepared by your Portuguese lawyer, with clear identification for both parties and the powers written clearly and unequivocally. You sign in front of the consular officer. A consular document does not need an apostille for use in Portugal, but the consulate authenticates the act; it is not there to repair weak drafting.

Before a local notary where you live. Expect the document to need a Hague Apostille from the competent authority in that country, followed by a certified translation into Portuguese. A Portuguese consulate states the point bluntly for foreign notarised powers: without the apostille, the document will not produce effects in Portugal. Build time for this route before you make an offer, not after the seller has accepted one.

The bank gets a vote

Before anyone signs, send the draft to every institution that will have to rely on it: the notary, the bank and, if you are borrowing, the lender or mortgage broker. Ask one direct question: will you accept this wording for the acts you must process?

That check sounds dull. It is the step that prevents a technically valid document from failing at the counter because the bank wanted account opening, direct debits, mortgage signing or identity checks expressed differently. A power of attorney is only useful if the people holding the next form accept it.

Keep control of the money

Authority to sign is not the same as a blank instruction to move money. Put your payment instructions in writing, separately from the power itself. Payments should follow reviewed documents, go to identified accounts and leave you with a receipt or completion copy for every step.

Ask three questions before any transfer: what document authorises this payment, who receives it, and what proof will I hold afterwards? If the answers are vague, stop. A careful lawyer will not be offended by the questions. They are the process.

One tax point not to confuse

The person who applies for your NIF as legal representative is not automatically your tax representative. Those are different roles in the tax authority's system. If you want the same person to receive tax correspondence and act as tax representative, the appointment needs to be dealt with expressly.

Owning a Portuguese property creates a tax relationship here. Before completion, settle how official tax notices will reach you: through a tax representative or through the official electronic notification channels that apply in your case. I cover the first month after completion in After the escritura.

Start before you find the house

The common mistake is to begin the power after the offer is accepted, when the CPCV deadline is already running. If you know you will buy from abroad, have your lawyer prepare the draft while you are still comparing areas and properties. The document can wait, properly limited and dated, until the right house appears.
