Power of Attorney: Buying in Spain Without Flying Over

Buying a new-build home on the Costa del Sol does not require you to be physically present in Spain on completion day. A Power of Attorney (in Spanish, a poder notarial or poder de representacion) lets you appoint someone you trust to act in your name, so the purchase can proceed while you stay abroad. This guide explains how a Power of Attorney works for foreign buyers, how to grant one from your home country, what it should and should not authorise, and where it fits alongside your other obligations such as the NIE, IRNR and the completion taxes.

What a Power of Attorney is and why remote buyers use one

A Power of Attorney is a notarised document in which you (the grantor, or poderdante) authorise another person (the attorney, or apoderado) to carry out specific legal acts for you. In a Spanish property purchase the attorney can obtain your NIE, open a bank account, sign the private deposit contract (contrato de arras), sign the public title deed (escritura publica) before the notary, pay the purchase taxes and register the property at the Land Registry (Registro de la Propiedad). Spain is a notarial jurisdiction, so a purchase is only fully protected once it is signed as a public deed before a Spanish notary and registered ⁴.

Remote buyers use a Power of Attorney for three reasons: new-build completion dates slip and are hard to plan flights around; the process involves several separate appointments (NIE, bank, notary, utilities) that rarely fall on the same day; and it removes the pressure of signing a life-changing document in a language you may not read fluently. The usual and safest attorney is your own independent, English-speaking lawyer, who owes duties only to you.

Special power or general power

You do not need to hand over sweeping authority. Two forms are common:

• A special Power of Attorney (poder especial), limited to one named transaction. It lists the specific property, the maximum price and the specific acts allowed. This is the safer choice for a single purchase.
• A general Power of Attorney (poder general), which grants broad authority over your Spanish affairs. It is convenient if you expect ongoing dealings, but it gives the attorney far more scope, so it should only ever be granted to someone you fully trust.

If you are also arranging a Spanish mortgage, note that signing a mortgage deed usually requires an explicit, separate power to borrow and to charge the property (a poder para hipoteca). A general purchase power does not automatically cover it, so tell your lawyer in advance if a loan is involved. Non-resident mortgages on the Costa del Sol are typically offered at lower loan-to-value ratios than for residents, so many overseas buyers complete as cash purchasers and remortgage later; this is a market practice rather than a legal rule ⁸.

Three ways to grant the Power of Attorney from abroad

You can create a valid Spanish Power of Attorney without setting foot in Spain. There are three routes.

1. Before a Spanish notary. If you happen to visit Spain briefly, or grant it on an earlier trip, a Spanish notary prepares and witnesses the deed directly. This is the simplest to use because it is already in Spanish and needs no legalisation.
2. At a Spanish consulate in your country. Spanish consulates provide notarial services, including granting powers of representation, for use in Spain ⁷. The document is issued in Spanish and needs no apostille because it is a Spanish official act. Appointments can take time to obtain, so book early.
3. Before a notary in your own country. Your local notary witnesses the power, after which it must be legalised for use in Spain. For countries in the 1961 Hague Convention, legalisation is done by the Apostille (Apostilla de La Haya), a single certificate added by the competent authority in your country ⁵. It then needs a sworn translation (traduccion jurada) into Spanish by an official translator. Countries outside the Hague Convention require full diplomatic legalisation instead.

Your Spanish lawyer should draft the exact wording (in Spanish, or bilingual) and send it to you before you sign, so the local notary simply witnesses an agreed text. A power drafted loosely abroad can be rejected by the Spanish notary or the Land Registry, forcing you to start again.

Remote video notarisation inside Spain

Spain has modernised its notarial system. Law 11/2023 introduced electronic notarial deeds and the possibility of granting certain instruments, including powers of representation, by secure video-conference through the official notarial platform ². In practice most foreign buyers still find it simplest to use a consulate or a local notary plus Apostille, and availability of the remote route for non-residents should be confirmed with your notary before you rely on it. Treat it as an emerging option, not a guaranteed shortcut.

The NIE still applies

Every foreign buyer needs a NIE (Numero de Identidad de Extranjero), the tax and identification number required to sign the deed and pay taxes. A well-drafted Power of Attorney can authorise your attorney to apply for the NIE on your behalf, so you avoid a consular or police appointment for that step alone ⁶. Make sure the power expressly includes obtaining the NIE, requesting it before the tax authorities and dealing with the police (Policia Nacional), otherwise the attorney may be turned away. See the related guide on obtaining your NIE for the full procedure.

What the attorney handles on completion

On the day, the attorney signs the escritura publica before the notary, hands over the funds (usually by bank transfer or banker’s cheque arranged in advance), and takes on the settlement steps that follow. For a new-build, that includes paying VAT and Stamp Duty rather than transfer tax:

Because IVA and AJD replace ITP on new-builds, your budget should assume roughly 10% VAT plus around 1.2% Stamp Duty on the purchase price, plus notary, registry and legal fees, rather than the resale transfer tax. See the related guides on completion costs and on buying off-plan for the full breakdown.

Off-plan safeguards the attorney should check

If you are buying off-plan and paying stage instalments before the home is finished, Spanish law requires the developer to guarantee those advance payments through a bank guarantee or insurance policy, a protection that originates in Ley 57/1968 and is now embedded in the building law (Ley de Ordenacion de la Edificacion) ⁹. Instruct your attorney or lawyer to obtain and hold the individual guarantee certificate for every payment you make. A remote buyer relies entirely on their representative for this check, so agree it in writing before any money leaves your account.

Ongoing obligations after you own the home

Owning on the Costa del Sol brings recurring duties that a good lawyer can also manage. As a non-resident owner you file the annual non-resident income tax (IRNR) on Modelo 210. Where the property is for your own use and not let, tax is charged on an imputed income based on the cadastral value; where you let it, you are taxed on the rental income. Rates are generally 19% for residents of the EU or EEA and 24% for other non-residents ¹. Separately, the town hall levies the annual IBI property tax, set locally as a percentage of the cadastral value. If you ever sell as a non-resident, the buyer must withhold 3% of the price and pay it to the tax authorities as an advance on your capital gains tax ¹. These figures should be confirmed for the year of your transaction, as rates and thresholds are reviewed periodically.

Costs, safeguards and revoking the power

Granting a Power of Attorney is inexpensive relative to the purchase: a notarial power is a short deed, and the Apostille and sworn translation add modest fixed costs. Keep three safeguards in mind. Prefer a special power tied to one property and a maximum price. Never grant a Power of Attorney to the seller, the developer or an agent acting for them, as that creates a clear conflict of interest. And remember you can revoke the power at any time before a notary (revocacion de poder); tell your attorney and the relevant notary if you do, because a revocation only protects you once it is properly notified.

Used correctly, a Power of Attorney turns a cross-border purchase into a manageable, remote process: your independent lawyer secures your NIE, checks the off-plan guarantees, signs the deed and settles the taxes, while you follow progress from home. The key is to keep the authority narrow, the wording drafted by your own side, and every figure confirmed for the year you complete.
