The Spanish Inheritance Power of Attorney: How Foreign Heirs Authorise a Lawyer to Act in Spain
For an international family dealing with a Spanish inheritance, the power of attorney (poder notarial para herencia) is the single most useful document in the file. Properly drafted, it lets your dedicated inheritance lawyer in Spain search registries, sign the deed of acceptance, file and pay inheritance tax, register property and close bank accounts on your behalf — without you ever needing to travel to Spain. Drafted poorly or signed in the wrong place, the same document becomes the obstacle that paralyses the file for months. This article explains the three ways a foreign heir can sign the power: before a notary in their home country with subsequent apostille, at a Spanish consulate, or in Spain itself. It then sets out what clauses the document must contain in order to be accepted by Spanish notaries, banks and the tax authority, the differences between a general and a special power, the time and cost involved in each option, and the recurring drafting errors that send a power of attorney back to the heirs for re-signing. We also explain when the power expires, how it can be revoked, and the precautions to take when several heirs grant a single power to the same Spanish lawyer.
Why a power of attorney is essential for a foreign heir
Spanish inheritance procedure is built around the personal appearance of the heirs before a notary. Every act — accepting the inheritance, partitioning the estate, valuing the assets, paying inheritance tax, registering property, closing bank accounts — requires a signature. For a family living in the same town as the deceased this is unremarkable; for a family scattered across the United Kingdom, the United States, the Netherlands or Australia it becomes a logistical nightmare. Multiple trips to Spain, coordinating diaries across time zones, taking days off work to attend a forty-minute notarial appointment: the costs add up quickly, and any single missed signature can stall the entire file past the six-month tax deadline.
The Spanish notarial power of attorney is the solution. A single document, signed once by the heir in their home country, transfers authority to a Spanish lawyer to perform every act required to settle the inheritance. The deed of acceptance, the tax return, the property registration: all are signed by the lawyer in the heir’s name. The heir is never required to travel. The cost of obtaining the power is a one-off expense — typically a few hundred euros per heir — and it is by far the most economical way to handle an inheritance from abroad.
Option one: signing before a notary in your home country
The most common route is for the heir to sign the power before a notary in their country of residence. In England and Wales, a notary public can produce the document; in Scotland, a Scottish notary; in the United States, a notary public in the relevant state. The notary attests the signature and confirms the identity of the signatory. The document is then apostilled by the central authority of that country — in the United Kingdom, the Legalisation Office of the Foreign, Commonwealth and Development Office — under the 1961 Hague Convention. The apostille is the only legalisation Spain requires. Detailed apostille guidance is included in our overview of the acceptance procedure for foreign heirs.
The text of the power must be in Spanish or in a bilingual format. A document drafted only in English is not accepted by Spanish notaries unless accompanied by a sworn Spanish translation. The cleanest solution is to use a bilingual model prepared by the Spanish lawyer in advance, which the foreign notary then witnesses. The lawyer in Spain can supply the exact text and the foreign notary simply attests the signature on it. This avoids back-and-forth and ensures that no clause is missing.
The timeline for this route is typically two to four weeks: one to two weeks to schedule and attend the notarial appointment, and one to two weeks for the apostille. In urgent cases the apostille can be expedited but the heir should plan for at least three weeks from instruction to delivery in Spain.
Option two: signing at a Spanish consulate
Spain operates consulates in London, Edinburgh, Manchester, New York, Washington, Los Angeles, Miami, Chicago and many other cities. Spanish consulates have full notarial authority and can issue a power of attorney directly in Spanish, with no apostille required. The document is then valid in Spain immediately. For heirs who live close to a consulate this is the cheapest and fastest route, with consular fees usually under €100 and no separate notary or apostille bill.
The drawback is appointment availability. The Spanish consulate in London routinely runs a six to twelve week wait for notarial appointments and the New York consulate is similar. For a family that has just had a death and is racing the six-month tax clock, the consulate route is often not fast enough. The practical advice is: check consular availability immediately on day one of the file; if an appointment is available within four weeks, use the consulate; otherwise, use a local notary and apostille route.
Option three: signing before a notary in Spain
If the heir is travelling to Spain for any reason — to attend a funeral, to visit family, or to inspect the property — they can sign the power of attorney before a Spanish notary directly. The cost is similar to a UK notary (around €60–€150) and there is no apostille step because the document is already Spanish. The heir needs to bring their passport and their NIE (Número de Identificación de Extranjero) or have the NIE obtained in parallel. NIE applications can be made through the same Spanish notary or, more efficiently, through the lawyer in Spain before the appointment. The mechanics of the NIE for inheritance are discussed in our guide to the NIE number for Spanish inheritances.
For an heir who can combine the notarial appointment with another reason to be in Spain, this is the most efficient route. For an heir who would have to make a special trip purely to sign, it usually does not justify the cost or time, and the foreign-notary route is preferable.
What the power of attorney must contain
A Spanish power of attorney for inheritance is a special power, not a general power. Spanish notaries refuse to accept a general power as authority to accept an inheritance, because the act of acceptance is considered exceptional and must be specifically authorised. The document must list, expressly: the authority to accept the inheritance with or without benefit of inventory; the authority to renounce the inheritance; the authority to partition the estate; the authority to value each asset; the authority to file and pay inheritance tax; the authority to sign the public deed of acceptance and partition; the authority to register property at the Land Registry; the authority to receive and dispose of bank funds; the authority to close accounts of the deceased; and the authority to grant sub-powers.
Omitting any one of these clauses can stop the file at the notarial appointment, because the notary will refuse to certify an act that is not specifically authorised. The cost of a missing clause is a new appointment, a new apostille, and a new round of translation — typically four to six weeks of delay. The drafting must be done by a Spanish-qualified lawyer who handles inheritance files routinely. We provide a tested bilingual model as part of every initial consultation; see our overview of the inheritance services we offer to foreign families.
General versus special powers
A general power of attorney (poder general) authorises the lawyer to act for the heir in all matters. A special power (poder especial) authorises specific acts, with each act listed. For an inheritance, a special power is normal: the heir is not granting a blanket authority over their affairs, only over the inheritance procedure. The special power is narrower, easier to control, and easier to revoke.
Some heirs prefer to grant a general power covering both the inheritance and any subsequent acts — for example, the sale of the inherited property, the management of rental income, or representation before the tax authority for any future audit. A general power is appropriate when the heir has an ongoing economic interest in Spain that they want a single lawyer to handle. For a one-off inheritance with no continuing Spanish business, a special power is cleaner.
Multiple heirs granting a single power
Several heirs can grant a single power to the same Spanish lawyer. Each heir signs their own power (or appears before the same notary on the same day to sign a joint power). The lawyer then represents all the heirs simultaneously at the inheritance deed. This is the standard arrangement for family inheritances and works well when the heirs are in agreement.
When the heirs are not in agreement, each side should grant their power to a separate lawyer. A single lawyer cannot ethically represent both sides of a partition dispute. The conflict-of-interest rule is strict in Spain and a lawyer who accepts a joint power from heirs who later fall out must withdraw from both sides, leaving the file unrepresented. Recognising the conflict early — at the first signs of disagreement — protects everyone.
Expiry, revocation and limits in time
A Spanish power of attorney does not expire automatically unless the document itself sets a time limit. Most powers are granted without a time limit and remain valid until revoked. The heir can revoke the power at any time by notarial act, with notice to the lawyer. Death of the heir also automatically extinguishes the power, although the lawyer’s acts before notification of the death remain valid.
Some banks and registries impose internal time limits on powers they will accept — often two to five years from the date of signature. If the inheritance file is long and the power is several years old, the bank may request a fresh power before unblocking funds. This is bank policy, not legal requirement, and a recent power is always preferable for that reason. For a typical inheritance completed within twelve months of the death, the original power remains valid throughout.
Common drafting errors that delay files
The recurring errors we see in powers of attorney drafted outside Spain are: omission of the authority to renounce (which prevents the lawyer from declining inheritance for an heir who would inherit only debts), omission of the authority to dispose of bank funds (which prevents the lawyer from transferring inheritance proceeds to the heir), omission of the authority to grant sub-powers (which prevents the lawyer from delegating to a colleague for a specific notarial act in a different region), and use of the wrong name format for the deceased (English versus Spanish word order). Each error sends the document back for re-signing.
A less obvious but equally damaging error is failing to include the heir’s tax identification number. If the heir does not yet have a NIE at the time of signing the power, the document should state that the NIE will be obtained through the lawyer named in the power. Without this clause, the lawyer may need a separate authority to apply for the NIE, adding weeks to the timeline. All of these traps are avoided by using a model drafted for the specific country pair. For a UK-Spain inheritance, see our country guide for British nationals inheriting in Spain.
How to start the process and what we need from you
To prepare the power of attorney, we need: the heir’s passport copy, the heir’s residential address, the heir’s NIE (or authority to apply for one), the deceased’s death certificate, and a summary of the known Spanish assets. With that pack we draft the bilingual power, send it to the heir, and the heir then signs it before a local notary or at a Spanish consulate. From signing to filing in Spain, the typical turnaround is three to five weeks if a UK notary and apostille are used, and one to two weeks if a Spanish consulate appointment is available quickly. To start a file, contact our inheritance team with the details above.
The power of attorney is the foundation of every remote inheritance file. Getting it right at the start prevents most of the delays and complications that affect foreign families. Getting it wrong adds weeks or months to the timeline at a moment when the six-month tax deadline is already pressing. The few hundred euros and few hours required to obtain a properly drafted, properly executed power are the best investment the heirs will make in the whole file.
