A power of attorney (poder notarial) allows someone to act on your behalf during a Spanish property purchase. If you can't be in Spain for every step of the process - and most non-resident buyers can't - granting power of attorney to your lawyer means the transaction can proceed without you being physically present for each signature, payment, or administrative task.
It's not mandatory. If you can attend the notary signing in person and handle all the administrative steps yourself, you don't need one. But for most international buyers, particularly those buying from another country, it's one of the most practical tools in the process.

A specific power of attorney is strongly recommended over a general one for property transactions
It must be executed before a notary - either in Spain or in your home country (with apostille)
Cost: 50-150 euros if done at a Spanish notary, more if done abroad with translation and apostille
It can be revoked at any time
What a power of attorney allows
When you grant power of attorney to your lawyer (or another trusted representative), they can carry out legal and administrative actions on your behalf. In the context of a Spanish property purchase, this typically includes signing the purchase deed (escritura de compraventa) at the notary, signing the mortgage deed if you're financing, paying deposits and the balance of the purchase price, applying for and collecting your NIE number, opening a Spanish bank account on your behalf (some banks permit this, others don't), signing utility contracts, setting up direct debits for property taxes, community fees, and insurance, and filing tax forms related to the property.
The scope depends entirely on what powers you grant in the document. This is why the distinction between general and specific powers of attorney matters.
General vs specific power of attorney
A general power of attorney (poder general) gives your representative broad authority to act on your behalf across a wide range of legal and financial matters. It's not limited to a specific transaction or property.
A specific power of attorney (poder especial) limits your representative's authority to named actions on a named property. For example, it might authorise your lawyer to sign the purchase deed for a specific apartment at a specific address for a specific price, and nothing else.
For property purchases, a specific power of attorney is strongly recommended. It gives your lawyer exactly the authority they need to complete the transaction while limiting what can be done in your name. A general power of attorney creates unnecessary risk - if the document were misused (however unlikely), the potential scope of damage is far greater.
Your lawyer will draft the specific power of attorney to cover all the actions required for your particular transaction. Review it carefully before signing, and make sure you understand every power being granted.
Where to execute it
A power of attorney must be executed before a notary. You have two options:
Option 1: At a Spanish notary (recommended if you're visiting Spain). This is the simplest and cheapest route. You visit a Spanish notary with your passport and NIE, the notary reads the document aloud (an interpreter is required if you don't speak Spanish), you sign, and it's immediately valid for use in Spain. Cost: typically 50-150 euros depending on the document's complexity and length.
Option 2: At a notary in your home country. If you can't visit Spain before the transaction needs to proceed, you can execute the power of attorney before a notary in your home country. However, for it to be valid in Spain, it needs to go through additional steps. The document must be drafted in Spanish (or translated by a certified translator). It must be notarised in your home country. It must then be apostilled under the Hague Convention (or legalised if your country isn't a Hague Convention signatory). This process adds cost (translation fees, notarisation fees, apostille fees) and time (typically 1-3 weeks depending on your country's apostille processing speed). Total cost abroad: 300-800+ euros including translation and apostille, depending on the country.
If you're planning a single trip to Spain before your purchase - which we recommend in our remote buying guide - executing the power of attorney during that visit is significantly cheaper and faster than doing it from abroad.
When you need it
The power of attorney needs to be in place before any action you want your representative to carry out. In practice, the key milestones where it's most commonly used are signing the arras contract (deposit contract) if you can't be present, signing the purchase deed and mortgage deed at the notary on completion day, and handling post-completion administration (registry, utilities, tax registrations).
Many buyers attend the notary signing in person (it's the moment you get the keys, after all) but grant power of attorney for the administrative steps before and after. Others grant full power of attorney and have their lawyer handle the entire process remotely. Either approach works - it depends on your travel flexibility and personal preference.
If you're attending the notary signing in person but want your lawyer to handle the NIE application, bank account opening, and post-completion admin, a power of attorney covering those specific tasks is sufficient. You don't need to grant signing authority for the deeds if you'll be there yourself.
The process step by step
1. Your lawyer drafts the document. They'll prepare the power of attorney in Spanish, tailored to your specific transaction. Review it carefully (ask for a translation if needed) and confirm you're comfortable with every power being granted.
2. You sign before a notary. Either at a Spanish notary or a notary in your home country (with subsequent apostille). Bring your passport and NIE. If at a Spanish notary and you don't speak Spanish, an interpreter will be arranged.
3. Your lawyer receives the original or an authorised copy. The notary provides authorised copies of the signed document. Your lawyer uses these to act on your behalf wherever required.
4. Your lawyer acts within the granted powers. They can now sign documents, make payments, and complete administrative tasks as specified in the power of attorney.
Revoking a power of attorney
A power of attorney can be revoked at any time by returning to a notary and signing a revocation document (revocacion de poder). If the power of attorney was specific to a single transaction and that transaction is complete, the practical authority expires naturally - but formally revoking it provides clean legal closure.
If you granted a general power of attorney (not recommended, but if you did), revoking it after the transaction completes is important. Don't leave a general power of attorney open-ended.
Cost summary
Method | Approximate cost | Timeline |
|---|---|---|
Spanish notary (in person) | 50-150 euros | Same day |
UK notary + apostille | 300-500 euros | 1-2 weeks |
US notary + apostille | 400-800 euros | 1-3 weeks |
Other countries | Varies | 1-3 weeks |
The Spanish notary route is cheaper and faster by a significant margin. If your timeline allows a trip to Spain before the transaction proceeds, executing the power of attorney during that visit is the most efficient option.
Frequently asked questions
Is a power of attorney mandatory to buy property in Spain?
No. If you can attend every step in person - the NIE application, bank account opening, arras signing, notary completion, and post-completion admin - you don't need one. But most non-resident buyers find it impractical to be present for every step, making it a near-essential practical tool.
Can I grant power of attorney to someone other than my lawyer?
Yes. You can grant it to any trusted person - a family member, friend, or professional. However, granting it to your Spanish property lawyer is the standard approach because they understand the legal process and are professionally regulated.
Does the power of attorney expire?
A specific power of attorney tied to a named transaction effectively expires once that transaction completes. A general power of attorney remains valid until revoked. You can also include an expiry date in the document if you prefer a defined time limit.
Can my lawyer open a bank account on my behalf with a power of attorney?
Some banks accept this, others don't. Bank policies vary, so confirm with your target bank before relying on this approach. CaixaBank and Santander are generally more flexible on this point. See our bank account guide for more detail.
Do both buyers need a power of attorney if purchasing jointly?
If both buyers can't attend in person, both need to grant power of attorney. Each person signs their own document. If one buyer can attend and the other can't, only the absent buyer needs one.
