Power of attorney for a Spanish property purchase: what to sign and who holds it

A poder notarial is a public deed. You are the poderdante, the person you appoint is the apoderado, and the notary keeps the original in the protocol and issues an authorised copy that travels.

A poder general hands over a broad catalogue of faculties: buy, sell, mortgage, litigate, open and close bank accounts, accept inheritances, deal with the tax office. Many standard drafts include the facultad de disponer, the power to dispose, which lets the holder sell your Spanish property to a third party without asking you. A general power stays alive until you revoke it, which could be years after the purchase you granted it for.

A poder especial is limited: one transaction, one purpose, an enumerated list of acts, normally one property.

Take the special one. It does everything a purchase requires and nothing beyond that. If the relationship with the holder breaks down, the worst outcome is a stalled purchase rather than a sold apartment and an emptied current account.

Whichever you sign, read the faculties clause line by line. The words that matter are disponer, enajenar, gravar and hipotecar: dispose, transfer, encumber, mortgage. A purchase power needs none of the first three.

Two routes to executing it, and what the deed must say

Signing in Spain, at any notary

This is the cheap, fast route. Walk into any Spanish notarial office with your passport and the deed is usually ready the same day or the next. You do not need an NIE first. The power itself can authorise your attorney to apply for one on your behalf.

The deed is written in Spanish. If you do not read Spanish, the notary will require either a sworn interpreter at the signing or a bilingual deed in two columns, because they have to be satisfied you understood what you granted. Ask your lawyer to arrange that when the appointment is booked, not on the morning.

The practical move is to sign the power during the viewing trip, before you have chosen anything, using the bounded drafting described below.

Signing from abroad

Two sub-routes, and they are not equal.

Spanish consulate or embassy. The consul exercises notarial functions. The document comes out in Spanish, already valid in Spain, with no apostille and no sworn translation, which makes it cleaner and cheaper than the alternative. The blocker is the appointment diary. Some consulates give a notarial slot inside a week, others run two or three months out, and notarial appointments (actos notariales) usually sit in a different queue from visa or NIE bookings. Check that calendar before you commit to a completion date. Most consulates also want the draft text from your Spanish lawyer several days in advance.

Local notary plus apostille plus sworn translation. Your Spanish lawyer drafts the power, a notary or notary public in your own country witnesses your signature, then two more steps follow. First the apostille under the 1961 Hague Convention, issued by the designated authority in that country: the FCDO Legalisation Office in the United Kingdom, the Secretary of State of the issuing state in the United States, the foreign ministry in most of Europe. Then, if the text is not already in Spanish, a traducción jurada by a translator sworn by the Spanish Ministry of Foreign Affairs. Then the paper original travels to Spain by courier, because a scan will not do at the completion table.

Realistic timing on that second route is two to four weeks, or about a week if you pay for an expedited apostille and next-day courier.

Two caveats on the apostille. It only works between states party to that convention. If your country is not one of them, it is replaced by full consular legalisation: your foreign ministry certifies the document, then the Spanish consulate there certifies that, a chain of stamps that is slower again. And there is no EU shortcut: Regulation (EU) 2016/1191 dropped the apostille for birth, marriage and criminal-record certificates between member states, but not for notarial powers, so a Dutch or German poder still needs one.

What the document must name to be usable

This is where powers fail, and the failure surfaces at the worst moment: the attorney is sitting in the notary's office, the seller is across the table, and one required act is missing from the text. The notary cannot improvise. You then re-execute from abroad while the arras deadline keeps running and your deposit sits exposed.

The deed has to identify you properly: full name exactly as it appears in your passport, passport number, nationality, date of birth, address, marital status and, if married, your matrimonial property regime. Notaries ask about the regime because it affects how ownership is entered at the Land Registry.

It has to identify the attorney: full name, NIE or passport number, address. Copy those details from the person's actual document, not from an email signature. A transposed digit in an NIE has stopped completions.

Then it has to enumerate the powers. A workable purchase list covers:

• signing the reserve contract and the contrato de arras, and paying the deposit
• signing the escritura pública de compraventa before any notary, agreeing price and terms
• applying for and collecting the NIE, including signing the forms and paying the fee (more on the NIE here)
• opening a bank account in your name and operating it, including the bank cheque for completion
• subscribing and paying utilities, community of owners fees and direct debits
• filing and paying the purchase taxes, and registering the deed at the Registro de la Propiedad
• collecting keys and taking possession
• signing a mortgage deed, if you are financing, subject to the caveat further down

Name the property if you have chosen it: address, cadastral reference, finca number. If you have not chosen yet, a competent drafter uses a bounded description, for example any urban property in the provinces of Alicante or Murcia up to a stated maximum price. That keeps one power usable across several candidates without turning it into a general power.

A long faculties list inside one transaction is not the danger. A list that reaches past it is. The real safeguards are the transaction limit and the expiry date, not a thin set of acts that leaves your attorney stuck at the counter.

Costs, expiry and revocation

Every figure below is indicative, not a quote. Spanish notarial fees follow a national tariff set by decree rather than the individual notary's judgement, so that line moves least, though extra copies and 21 per cent IVA sit on top. Consular fees follow their own published tariff, so check the consulate's page. Everything else depends on your country, your local notary and how fast you need it, so ask for a written quote.

Item	Indicative cost	Indicative time
Poder especial at a Spanish notary, one authorised copy	EUR 40 to 90 plus IVA	Same day or next day
Sworn interpreter at the Spanish notary, if required	EUR 80 to 200	Booked with the appointment
Poder at a Spanish consulate abroad	EUR 40 to 70	Appointment wait of 1 to 10 weeks
Local notary or notary public abroad	EUR 60 to 250	1 to 5 days
Hague apostille	EUR 10 to 80	1 to 15 working days
Traducción jurada of a short power	EUR 60 to 180	2 to 5 working days
International courier for the original	EUR 30 to 80	2 to 5 working days
Lawyer drafting and reviewing the power	EUR 150 to 400 plus IVA	1 to 3 days

Signing in Spain tends to land near EUR 200 to 500 once your lawyer's drafting time is counted. The full route abroad with a local notary, apostille, translation and courier more often lands between EUR 400 and EUR 900. The consulate route sits in between, and its real cost is the waiting. None of it is large against a purchase, but it belongs in the budget alongside the other line items in the total cost of buying in Spain and your lawyer's fees.

Expiry, revocation and the copy the notary will want

A Spanish power does not lapse on its own. Unless the deed sets an end date it stays in force until you revoke it, so ask for an expiry clause of six or twelve months, set comfortably beyond your expected completion. Off-plan buyers should stretch that rather than grant something open-ended.

You revoke by signing a deed of revocation (escritura de revocación) at any Spanish notary or at a consulate. Revocation does not bite against the attorney until they know about it, so notify them formally, keep proof, and tell your lawyer and the completing notary as well. The power also ends on your death, and it can end if a court later appoints someone to represent you, which is why a poder preventivo, drafted to survive that, is a separate instrument.

Expect the completing notary to ask for a recent copia autorizada. Notaries check that a power is still in force before letting anyone sign in another person's name, and anything more than a year old routinely draws a request for a fresh copy. Build a few days into the schedule, and order that copy early if you are close to a deadline. The Consejo General del Notariado runs the public directory of Spanish notaries if you need to trace the office holding your original protocol. Our note on what a Spanish notary does and does not do explains why they will not fill these gaps for you.

Two drafting habits worth adopting. Name a natural person rather than a law firm. And name a second attorney able to act indistintamente, meaning either one alone, so a holiday or an illness does not stall completion.

Who should hold the power, and the mortgage exception

We are an estate agency, and this next part costs us convenience, so read it as written. Your power of attorney should sit with a lawyer who acts only for you. Not with us. Not with the selling agent, the developer's sales office, the seller's gestor, or anyone whose fee depends on the deal closing on the seller's terms.

The reason is structural rather than moral. Whoever holds the power can sign the arras, accept the price, waive a condition you would have argued about, and sign the escritura. A person negotiating for the seller cannot also be the person accepting those terms on your behalf, and no assurance about good intentions changes that. Spanish law has a name for one representative standing on both sides of a contract, autocontratación, and a power does not carry it by default. The deed has to authorise self-contracting expressly, and without that clause the notary will not let the attorney act on both sides. Do not grant it. Ask your lawyer for their Colegio de Abogados registration number and confirm they carry professional indemnity cover before the power leaves your hands.

The mortgage exception catches people. Spanish lenders frequently want the borrower present in person. The mortgage transparency rules add a step on top: before the mortgage deed, the borrower attends a free advisory session with a notary and signs the acta de transparencia, no later than the day before completion. Whether an attorney can stand in at that session is contested, and plenty of notaries and lenders will not accept one. Some banks accept a power drafted on their own template, some insist on their own wording, and some refuse one for the mortgage element even where they accept it for the purchase. If you are financing, get the bank's position in writing before you spend anything on drafting, apostilles or translations. Our guide to mortgages for non-residents covers what lenders ask for.

The common workaround: you attend personally for the mortgage signing, and the attorney handles the NIE, the bank account, the utilities and the registration around it. The power still earns its cost, it just does not remove the trip.

Frequently asked questions

Can I sign a Spanish power of attorney by video call?

Not for a purchase power, in practice. Article 17 ter of the Ley del Notariado sets a closed list of acts a notary may authorise by video conference. Property sales, mortgage loans, donations and inheritance deeds are all off that list, and the article expressly bars general and preventive powers from the remote route. Powers for specific acts do appear on it, but notaries have not stretched that to purchase powers, and the platform requires a Spanish electronic identity and qualified signature that most non-resident buyers do not hold. Plan on attending in person.

Do I need an NIE before I can grant the power?

No. You grant the power on your passport and include the faculty for your attorney to apply for and collect your NIE. That is one of the most common reasons to use a power at all, since the NIE appointment queue and the completion date rarely line up.

My spouse is travelling to Spain. Can they sign for both of us?

Only if you have granted them a power. Marriage does not make one spouse the other's legal representative in Spain. If you are buying jointly, each buyer grants a power, either in separate deeds or in a single deed where both grantors appear and sign.

Can the same lawyer hold powers for the buyer and the seller?

Only with an express self-contracting clause in both powers, and you should refuse it. One lawyer, one side. A second independent lawyer costs very little against the value of having someone whose only obligation is to you.
