The Spanish inheritance process for American heirs

American families often assume that settling a Spanish estate works like a US probate: the executor files with a court, the will governs, and the assets pass to the heirs. Spain does it differently. There is usually no court probate for a normal inheritance. Instead, the heirs assemble a set of official certificates, prove who they are, sign a notarial deed accepting the inheritance, pay inheritance tax within a strict deadline, and register the assets in their names. It is administrative rather than judicial, and it moves on Spanish timelines and Spanish paperwork rules.

This guide is for the heirs of Americans who retired to Spain on the non-lucrative visa or otherwise held Spanish property or accounts. It focuses on the process — the steps, the order and the documents — rather than the tax calculation itself, which we cover separately in US estate tax vs Spanish inheritance tax. If the estate also includes American real estate, directly held US shares or a US account that will not release on foreign papers alone, read the separate note on US ancillary probate and US-situs assets for Spanish heirs. It is general information, not legal, tax or estate advice, and it does not replace a Spanish notary or a qualified adviser reviewing the specific estate.

"American families are used to probate, so the Spanish process feels backwards: no court, but a strict tax clock and a stack of certificates that gate everything else. The families who do well are the ones who request the certificates and the NIEs immediately and sign a power of attorney, so the notarial deed and the tax filing happen comfortably inside the six months."

Probate vs the Spanish way

In the United States, an estate typically passes through a probate court, an executor is appointed, and the court supervises distribution. In Spain, a straightforward inheritance rarely touches a court at all. The heirs themselves — helped by a notary and usually a lawyer — carry out the acceptance and division of the estate through a public deed. The Spanish notary is not a judge; the notary authenticates the deed, confirms identities and titles, and records the acceptance so that banks and the property registry will recognize the new owners.

For a US family this has two big consequences. First, there is no single "executor" with automatic authority over Spanish assets; the heirs generally act together, or through a power of attorney. Second, the process is document-driven. Spain will not simply accept a US will and a US death certificate at face value. Foreign documents usually need an apostille and a sworn translation, and the Spanish last-wishes system has to be checked before anything else can move.

Step 1: the three certificates

Almost every Spanish inheritance starts with the same three official documents. The first is the death certificate (certificado de defunción). If the person died in Spain, it comes from the Spanish civil registry; if they died in the United States, the US death certificate normally needs an apostille and a sworn translation to be usable in Spain.

The mirror image of that sentence is worth stating, because it catches American families the other way round. Where the retiree died in Spain, the Spanish certificate opens the Spanish succession quickly — but US banks, insurers and probate courts often will not accept it, and the document they do want, the Consular Report of Death, can take months to arrive. We set out that sequence, and the 48-hour decision that comes before it, in what happens when a US retiree dies in Spain.

The second is the certificado de últimas voluntades, the last-wishes certificate. This is the document that tells you whether the deceased made a Spanish will and, if so, before which notary. It is requested from the Spanish Registry of Last Wills, and as a rule it can only be obtained once fifteen business days have passed since the death (not counting the day of death, weekends or holidays), because the registry needs that time to update its records. It is requested using an official fee form (Modelo 790) together with the death certificate. This certificate is not optional: Spanish notaries will not authorize an acceptance deed, registries will not register, and banks will not release balances without it.

The third is the certificado de contratos de seguros de cobertura de fallecimiento, the insurance-contracts certificate, which reveals whether the deceased held any Spanish life-insurance policies naming beneficiaries. It is requested from the same registry, often at the same time and on the same form as the last-wishes certificate.

Step 2: the will or declaration of heirs

Once the last-wishes certificate identifies whether there is a Spanish will, the path splits. If the deceased signed a Spanish will, the heirs obtain an authorized copy from the notary who holds it, and that will governs the Spanish assets. Many foreign residents deliberately sign a Spanish will limited to their Spanish property precisely to make this step fast and local, coordinated with their US estate plan so the two do not conflict.

If there is no Spanish will, the family may rely on a US will — which will need probate evidence, an apostille and a sworn translation to be recognized in Spain — or, where there is no valid will at all, the heirs establish who inherits through a Spanish declaración de herederos, a notarial declaration of heirs. This adds time and documentation, which is one of the strongest arguments for signing a Spanish will while the owner is alive. If the US plan uses a revocable trust, read it alongside the guide to US living trusts and the non-lucrative visa, because Spain may still require a tax and document trail. Cross-border succession rules can also affect which country's law governs the estate, so this is a point to confirm with a Spanish adviser rather than assume.

Step 3: NIE and documents for US heirs

Every heir who will sign the deed, pay tax or take title needs a Spanish NIE (Número de Identidad de Extranjero), the foreigner identification number. American heirs who have never lived in Spain usually do not have one, so this is arranged early — either in Spain or through a Spanish consulate in the United States — so it does not hold up the notarial deed later.

Beyond the NIE, each heir needs valid identity documents, and the estate file needs proof of title and value for the Spanish assets: property deeds and registry information for real estate, and bank certificates showing balances at the date of death for accounts. Because so many US heirs cannot easily fly to Spain, powers of attorney are the practical workhorse of the whole process. An heir in the United States can sign a power of attorney before a US notary, have it apostilled and translated, and a lawyer in Spain can then act for them at the notary and the tax office. That estate power is different from the lifetime Spanish preventive power of attorney a retiree may sign while alive for incapacity planning.

Document	Where it comes from	Usual extra step for US families
Death certificate	Spanish civil registry or US vital records	Apostille + sworn translation if issued in the US
Certificado de últimas voluntades	Spanish Registry of Last Wills (Modelo 790)	Wait ~15 business days after death
Insurance-contracts certificate	Same registry, same form	Requested together with last-wishes
Will / declaration of heirs	Spanish notary or US probate	Apostille + sworn translation if a US will
NIE for each heir	Spain or Spanish consulate	Arrange early to avoid delay
Power of attorney	US notary	Apostille + sworn translation

Step 4: the notarial acceptance deed

With the certificates, will and identities in hand, the heirs sign the escritura de aceptación y adjudicación de herencia — the public deed of acceptance and allocation of the inheritance — before a Spanish notary. This deed is the heart of the process. In it, the heirs accept the inheritance, an inventory of assets and their values is set out, and the assets are allocated among the heirs according to the will or the declaration of heirs.

The deed can be signed in person by the heirs or, far more commonly for US families, by a lawyer acting under power of attorney. It is worth pausing on one point: accepting an inheritance in Spain can be done outright, or "to the benefit of inventory" (a acceptance that limits the heir's exposure to the estate's debts). Because a US family may not know the full picture of a deceased relative's Spanish liabilities, this is exactly the kind of decision to review with a Spanish lawyer before signing, not afterward.

Step 5: the six-month tax deadline

This is where a Spanish inheritance surprises American families most. Spanish inheritance tax (Impuesto sobre Sucesiones y Donaciones) has a hard filing deadline: the general period for a death is six months from the date of death. An extension of up to a further six months can be requested, but only within the first five months, and a granted extension carries late-payment interest. Miss the deadline entirely and the estate faces surcharges and interest on top of the tax.

The heir is the taxpayer, and each heir files their own self-assessment — the main form for inheritances is Modelo 650. Where the case is a non-resident matter, it can be handled through the Spanish Tax Agency's non-resident inheritance and gift tax channel; resident cases follow the competent autonomous community. How much is actually due depends heavily on the region, the relationship and the allowances — Andalucía, where Málaga sits, is generous for close family in many common situations — which is why the tax figure and the process should be planned together, not in isolation. The important process point is simply this: the clock starts at death, not at the moment the family gets organized.

Step 6: registering the assets

Signing the deed and paying the tax makes the heirs the legal owners, but the job is not finished until the assets are put in their names. For real estate, the acceptance deed, together with proof that inheritance tax has been paid or filed, is taken to the Registro de la Propiedad (Land Registry) so the property is registered to the new owners. There may also be a local municipal capital-gains tax on urban land (the plusvalía municipal) to settle around the transfer, which is separate from inheritance tax but part of the same practical project.

For bank accounts and investments, the heirs present the deed, the tax proof and their identification to the Spanish bank, which then releases or transfers the funds. Banks are cautious and will insist on the full paper trail, including the last-wishes certificate. Only once the registry and the banks have recognized the new owners can the family actually use or sell the inherited assets.

Common mistakes

The most common and damaging mistake is treating the six-month tax deadline as flexible. Because the family is often grieving and spread across two countries, months can pass before anyone requests the certificates — and the certificate itself cannot be requested until fifteen business days after death. Starting the NIE, the certificates and the power of attorney early is what protects the deadline.

A second mistake is assuming a US will is enough on its own. It may be valid, but without probate evidence, an apostille and a sworn translation it will not move a Spanish notary or registry, and relying on it alone is usually slower and more expensive than a Spanish will limited to Spanish assets. A third is forgetting the NIE until the last moment, then discovering the notarial deed cannot be signed. A fourth is overlooking debts and the option to accept "to the benefit of inventory" before signing. A fifth is treating the property registry and the bank as afterthoughts: until they update the ownership, the heirs cannot sell, mortgage or freely use what they have inherited. And for US families, a sixth is assuming the tax question is only American; the companion guide on US estate tax versus Spanish inheritance tax explains why the Spanish side still needs its own review, and a US heir who inherits above the threshold from a non-US relative usually also has to file an information return — see Form 3520 for foreign gifts and inheritances, which reports the bequest to the IRS even though it is not US-taxed. In a cross-border estate, the paperwork sequence is not clerical detail — it is the difference between an orderly inheritance and a file that sits frozen for a year.
