Power of Attorney in Spain — Complete Legal Guide (2026)

What Is a Power of Attorney in Spain?

A Power of Attorney (PoA), known in Spanish as a Poder Notarial, is a legally binding document that grants one person (the attorney-in-fact or apoderado) the authority to act on behalf of another (the grantor or poderdante). In Spain, all Powers of Attorney must be formalised before a notary public (notario) to have legal effect.

Spain’s notarial system differs significantly from common law countries like the UK or US. A Spanish PoA is not simply a signed document — it becomes a public instrument (escritura pública) entered into the notary’s protocol, giving it full evidentiary value before courts and public registries.

Types of Power of Attorney in Spain

1. General Power of Attorney (Poder General)

A General PoA grants broad authority to act across a wide range of legal and financial matters. This is commonly used when the grantor will be absent from Spain for an extended period or cannot manage their affairs personally. It typically covers:

Important: Spanish succession follows two distinct paths depending on whether the deceased left a valid will (testate) or not (intestate). The intestate path requires a Declaration of Intestate Heirs (Declaración de Herederos Abintestato) — a step not needed when a will exists. Learn more about the succession process →

• Buying, selling, and managing property
• Opening and operating bank accounts
• Signing contracts and legal documents
• Representing the grantor before government bodies
• Managing tax filings and payments
• Handling inheritance proceedings

Important: A General PoA does not authorise the attorney to make gifts or donations on your behalf unless this is explicitly stated, as Spanish law requires specific authorisation for acts of disposición gratuita.

2. Special Power of Attorney (Poder Especial)

A Special PoA is limited to a specific transaction or set of transactions. It is the most common type used in Spanish property purchases, where a buyer appoints a lawyer to sign the title deed (escritura de compraventa) on their behalf. Examples include:

• Purchasing or selling a specific property
• Applying for a NIE (tax identification number)
• Signing a mortgage deed
• Accepting or renouncing an inheritance
• Representing you in a specific court case
• Registering a company

3. Healthcare Power of Attorney (Poder Preventivo / Documento de Voluntades Anticipadas)

Spain recognises two related instruments for healthcare and incapacity planning:

• Poder Preventivo: A PoA that remains valid (or comes into effect) when the grantor loses mental capacity. Since the 2021 reform (Ley 8/2021), this has become the primary tool for incapacity planning in Spain, replacing the old guardianship (tutela) system.
• Documento de Voluntades Anticipadas: A living will that sets out healthcare preferences for end-of-life situations, registered with the regional health authority.

The 2021 reform strongly encourages all adults to execute a poder preventivo as a safeguard, making it one of the most important documents for expats living in Spain.

4. Litigation Power of Attorney (Poder para Pleitos)

Required to authorise a procurador (court representative) to act in judicial proceedings on your behalf. This is separate from your lawyer’s mandate and is necessary for most Spanish court proceedings.

When You Need a Power of Attorney in Spain

Property Purchases

If you cannot attend the notary signing in person, a Special PoA allows your lawyer to complete the purchase on your behalf. This is extremely common for international buyers. See our guide to buying property in Spain for the full process.

Inheritance and Probate

Foreign heirs often need to grant a PoA to a Spanish lawyer to handle the acceptance of inheritance, tax payments, and property transfers. This is especially important when the heir resides outside Spain. Read our probate and succession guide.

Business Operations

Company directors who are non-resident may grant a General PoA to a trusted person in Spain to manage business operations, sign contracts, and deal with the Tax Agency (Agencia Tributaria).

Tax and Administrative Matters

Non-resident property owners commonly appoint a fiscal representative via PoA to file annual tax returns (Modelo 210, Modelo 720) and handle municipal taxes.

NIE Applications

While some NIE applications can be done by a representative, most police stations now require personal attendance. However, a PoA can still be useful for related administrative steps.

How to Grant a Power of Attorney in Spain

If You Are in Spain

1. Instruct a lawyer: Your lawyer drafts the PoA text specifying exactly what powers are being granted and to whom.
2. Book a notary appointment: Both the grantor and their identification documents (passport, NIE) must be presented.
3. Attend the notary: The notary verifies your identity, ensures you understand the document (providing a sworn translator if needed), and executes the PoA as a public deed.
4. Collect the authorised copy: The notary issues a copia autorizada which your representative will use.

If You Are Outside Spain (Non-Residents)

Non-residents have several options for granting a Spanish PoA without travelling to Spain:

Option A: Spanish Consulate

Visit the nearest Spanish Consulate in your country. The consul acts as a notary and can execute the PoA directly under Spanish law. This is the simplest and most commonly used method. Costs are typically 30-60 EUR.

Option B: Local Notary + Apostille

Execute the PoA before a notary in your own country, then:

1. Obtain an Apostille (for Hague Convention countries) or legalisation
2. Have the document translated into Spanish by a sworn translator (traductor jurado)
3. Your Spanish lawyer presents the apostilled, translated document to the relevant authority

This method is more expensive and time-consuming but may be necessary if there is no Spanish consulate nearby.

Option C: Video-Conference Notarisation

Since 2023, some Spanish notaries accept video-conference appearances for certain PoA types, particularly in property transactions. This is still evolving and not universally available.

Revoking a Power of Attorney in Spain

A Power of Attorney in Spain can be revoked at any time by the grantor, provided they have legal capacity. The revocation process involves:

1. Execute a revocation deed: Visit a Spanish notary (or consulate) and sign a formal revocation document (escritura de revocación de poder).
2. Notify the attorney-in-fact: The revocation must be communicated to the person who held the power. Until notified, actions taken in good faith by the attorney may still be valid.
3. Notify relevant third parties: Banks, registries, and other institutions that were dealing with the attorney should be informed.

Automatic termination: A PoA also ends upon the death of the grantor, the death or incapacity of the attorney, or the completion of the specific task (for Special PoAs). A poder preventivo is the exception — it survives the grantor’s incapacity by design.

Power of Attorney for Non-Residents: Special Considerations

Non-residents face additional requirements when granting or using a PoA in Spain:

• NIE requirement: Both the grantor and the attorney-in-fact typically need a NIE (tax identification number) for property and tax-related powers.
• Apostille requirement: Any foreign document must bear the Hague Apostille (or full consular legalisation for non-Hague countries) to be valid in Spain.
• Sworn translation: All foreign-language documents must be accompanied by a certified translation by a Spanish traductor jurado.
• Consular option: The Spanish consulate route avoids the apostille and translation requirements since the document is executed directly in Spanish.
• Tax representative: Non-resident property owners should consider including tax representation powers in their PoA to allow their lawyer to file annual returns.

The other side of this is worth knowing before you grant one. An unrevoked power of attorney is a live power, and the misuse of old or forged powers is the usual mechanism behind a property sold without its owner’s knowledge. What to do if your Spanish property was sold without your consent
