The Complete Guide to Spanish Inheritance for International Families (2026 Edition)
This is the comprehensive reference for any international family facing a Spanish inheritance. It consolidates the law, the procedure, the tax, and the practical execution into a single guide that takes the reader from the moment of death to the registration of the inherited assets in the heirs’ names, with the full perspective of cross‑border complications. The guide is written for British, American, German, Dutch, French, Irish and other foreign heirs and is equally useful as background reading for the heir who has just been informed of a Spanish inheritance and as a checklist for the lawyer handling the file. It covers: the EU Succession Regulation and the choice‑of‑law clause; the six‑month inheritance tax deadline and the procedures to meet it; the role of the Spanish notary and the deed of acceptance; the regional reductions (especially the Andalusian 99% reduction); the interaction with home‑country inheritance and estate taxes; the practical mechanics of the power of attorney and the NIE; the management of inherited tourist licences; the strategies for renunciation or benefit of inventory in problematic estates; the planning steps a foreign national should take during life to make the eventual file simpler. A dedicated international inheritance lawyer in Spain is the appropriate professional to manage the file.
Why a Spanish inheritance is structurally different from an English or American one
The first thing a foreign heir needs to understand is that the Spanish system has no real equivalent of probate. In England and Wales, an estate is administered by an executor named in the will, probate is granted by the court, and the executor distributes the assets to the beneficiaries once debts and taxes are paid. The beneficiaries themselves rarely sign anything. In the United States, the equivalent system varies by state, but the core idea is similar: a personal representative is appointed, the court supervises the administration, and the beneficiaries receive their share at the end. The Spanish system inverts this. There is no executor and no probate court. The heirs themselves appear before a notary, declare that they accept the inheritance, identify each asset, calculate the tax, and pay it. The notarial deed of acceptance is the central document, and without it no Spanish bank will release funds and no property can be registered in the heirs’ names.
For a British or American family this means three practical consequences. First, the heirs cannot stand back and wait for the estate to be administered — they must take the file forward themselves (typically through a Spanish lawyer acting under their power of attorney). Second, the entire procedure happens in Spanish, before Spanish public officials, applying Spanish law and Spanish forced‑heir rules unless the deceased made a valid choice of foreign law. Third, the timeline is much tighter than UK or US probate: the Spanish inheritance tax must be filed and paid within six months of the date of death, regardless of where the heirs are or what other procedures are pending. The detailed comparison with UK probate is set out in our country guide on British nationals inheriting in Spain.
The structural difference also has cost implications. Spanish notarial fees, Land Registry fees and lawyer fees together are typically in the order of 2–4% of the gross estate value for a standard international file. The Spanish inheritance tax itself, for direct family inheritances in regions with strong reductions (Andalusia, Madrid, Valencia), is often a few hundred euros — the procedural cost is now the dominant component for most family estates. We will return to the cost calibration in the dedicated section later in this guide.
The EU Succession Regulation and the choice of law
Regulation (EU) 650/2012, often called Brussels IV, is the framework that governs cross‑border succession in the European Union for deaths after 17 August 2015. Spain is fully bound by the regulation. The default rule is that the entire succession is governed by the law of the deceased’s habitual residence at death, with a single law applying to the whole estate, wherever the assets are situated and whatever the nationality of the heirs. This was a major simplification compared with the pre‑2015 patchwork of national rules.
The regulation also gives the testator a powerful tool: article 22 allows any person to choose, in their will, the law of any state of which they are a national at the time of the choice or at the time of death. The choice must be express — it cannot be inferred from circumstances — and must be made in a valid testamentary disposition. Once made, the chosen law governs the whole estate. A British national resident in Spain who makes a Spanish will choosing English law has her Spanish estate governed by English law, not by Spanish forced‑heir rules. A German national in Marbella who makes the same choice has her estate governed by German law. The choice clause is the central protective device for foreign testators living in Spain and is explained in detail in our overview of the EU Succession Regulation.
For a UK national who died after Brexit but who lived in Spain, the regulation continues to apply in Spain even though the UK no longer participates in it (Spain’s application of the regulation does not require reciprocity). A British testator can therefore still choose English law in a Spanish will. For an American national, the choice can be of the law of any US state of which the testator is a national — typically the state of domicile (New York, California, Florida, etc.). The choice is given full effect in Spain. The substantive consequences of the choice can be dramatic, particularly when the chosen law gives the testator more freedom of disposition than Spanish law (which reserves two‑thirds of the estate for the descendants).
Spanish forced‑heir rules — what happens when no choice is made
When no valid choice of foreign law has been made, and the deceased was habitually resident in Spain at death, Spanish succession law applies. The most important feature is the system of forced shares (legítima). The descendants must take at least two‑thirds of the estate: one‑third as the strict legítima, divided equally among the children, and one‑third as the mejora, which the parent can use to favour one child over the others. The surviving spouse takes a usufruct (right of use and enjoyment) over part of the estate, the extent depending on whether there are descendants, ascendants or only the spouse. The remaining one‑third is freely disposable.
For a foreign testator this can be a real surprise. A British or American parent who expected to leave the entire estate to a new spouse, or to a single favoured child, or to a charity, will find that Spanish forced‑heir rules override the will to the extent that they protect the children’s legítima. The only way to avoid this — only available during the testator’s lifetime — is to make a Spanish will with a choice clause for the law of the testator’s nationality. After death, the rules are fixed, and the heirs must work within them. Practical settlement among heirs (by agreement on the partition) can still produce a result close to what the testator would have wanted, but this depends on the agreement of all the forced heirs.
The six‑month inheritance tax deadline
The Spanish inheritance tax (Impuesto sobre Sucesiones y Donaciones, ISD) must be filed and paid within six months from the date of death. The deadline is set by article 67 of the regulations to the ISD Act and is strict. It runs from the date of death — not from the date the heirs are notified, not from the date probate is granted in another jurisdiction, not from the date the heirs decide to accept the inheritance. After month six, automatic surcharges start at 5% and escalate to 20% after twenty‑four months, plus statutory interest. The mechanics of the deadline, including the procedure to request a six‑month extension within the first five months, are set out in our guide on the six‑month deadline for Spanish inheritance tax.
For UK and US families the deadline is particularly dangerous because home‑country probate routinely takes longer than six months. The Spanish authorities do not wait for foreign probate. The practical solution is to decouple the two procedures: the Spanish file is built directly from the death certificate, the will (UK or Spanish), and the heirs’ identification documents, and runs on the Spanish timetable independently of whatever is happening in the home country. The Spanish inheritance tax can usually be filed even before UK or US probate is granted, because Spanish tax only applies to Spanish‑situs assets and to the heirs personally, not to a foreign probate estate as such.
When the file genuinely cannot be completed in six months — the heirs are unknown, there is a will dispute, the assets are still being located — the right strategy is to request the six‑month extension within the first five months, and then to file a provisional declaration close to the twelve‑month mark, supplementing it later if necessary. This is far preferable to allowing the surcharges to start.
Regional reductions: the Andalusian 99% reduction and equivalents
Spanish inheritance tax is a state tax but has been substantially devolved to the autonomous regions. The regional reductions are dramatic and have transformed the effective tax burden over the last ten years. In Andalusia, since 1 January 2019, spouses, descendants and ascendants benefit from a 99% reduction in the regional tax due. Madrid has applied similar reductions for decades. Valencia introduced a 99% reduction for spouses and direct descendants in 2023. Catalonia operates a more nuanced reduction depending on the size of the estate and the relationship to the deceased. The differences across regions can mean a tax of near zero in Andalusia versus tens of thousands of euros in another region for an identical estate. The mechanics are discussed in our overview of reducing Spanish inheritance tax.
The choice of region is determined by the deceased’s last habitual residence (for residents) or by the location of the most valuable Spanish asset (for non‑resident deceased). Heirs cannot choose the region they would prefer. The European Court of Justice judgments of 2014 and 2018 forced Spain to extend the regional reductions to non‑resident heirs and to inheritances from non‑resident deceased, so there is no longer a tax disadvantage for foreign families — but applying the reductions correctly requires a precise reading of the regional rules in the file.
For families inheriting an Andalusian property from a UK‑resident or German‑resident parent, the Spanish inheritance tax is now typically a few hundred euros for the entire family. The procedural cost (lawyer fees, notary, registry, apostilles, translations) is now a much larger component of the total cost than the tax itself. The professional handling of the file ensures both that the regional reductions are properly claimed and that the procedural steps are completed within the six‑month window.
The Spanish notarial deed of acceptance
The deed of acceptance and partition (escritura de aceptación y partición) is the central document of the Spanish inheritance procedure. It is signed by all the heirs (or by their attorneys under power of attorney) before a Spanish notary. The deed contains five core elements: the identification of the deceased and the heirs; the inventory of assets and debts at the date of death; the valuation of each item; the attribution of specific assets to specific heirs; and the calculation of any compensating payments (excesos de adjudicación) where one heir receives more than their proportional share. The notary verifies the legal capacity of each signatory, the title to each asset, and the consistency of the partition with the will and with Spanish forced‑heir rules.
Once signed, the deed is the title document. The Spanish Land Registry uses it to register property in the heirs’ names. Banks use it to release accounts. The DGT uses it to register vehicles. Spanish tax offices use it to confirm the inheritance‑tax declaration. Errors in the deed — particularly mis‑valuations or omitted assets — create problems years later, when the heir sells the property or applies for a refund and discovers a mismatch with the cadastral value or with the bank record. The deed should be drafted by the heirs’ lawyer in Spain in advance of the notarial appointment, not improvised at the notary’s office.
The remote procedure: power of attorney and NIE
For foreign heirs unable or unwilling to travel to Spain, the entire procedure can be handled remotely through a Spanish power of attorney (poder notarial para herencia). The power authorises the Spanish lawyer to act in the heir’s name: search registries, sign the deed of acceptance, file and pay inheritance tax, register property and close bank accounts. The power can be signed before a notary in the heir’s home country (with subsequent apostille under the Hague Convention) or at a Spanish consulate abroad. Detailed mechanics in our guide on the Spanish inheritance power of attorney.
Each foreign heir also needs a Spanish NIE (Número de Identificación de Extranjero) before the deed of acceptance can be signed. The NIE can be obtained at a Spanish consulate abroad, in person at a Foreigners Office in Spain, or through the Spanish lawyer under the power of attorney. The lawyer‑delegated route is usually the fastest (3–4 weeks) and is the standard for international files. Full details in our guide on the NIE number for Spanish inheritances.
Locating Spanish assets
Before the inheritance tax return can be filed and before the deed of acceptance can be signed, the heirs need a complete inventory of the deceased’s Spanish assets. The Spanish registry system is comprehensive but fragmented: separate registries for real estate (Land Registry), bank accounts (each bank issues a certificate of balances), vehicles (DGT), life insurance (Insurance Registry), securities (through bank custodians), and business interests (Mercantile Registry). The lawyer’s asset‑location phase typically takes three to five weeks and is the foundation of every defensible inheritance file.
Heirs who file an incomplete inheritance tax return because they did not know about an asset face the same penalty regime as heirs who deliberately concealed it — the tax authority does not distinguish between negligent and willful omissions for the purposes of the basic complementary assessment, although willful concealment can trigger criminal proceedings as well. The defensive strategy is to identify every Spanish asset before the return is filed and to include each one with a defensible value.
Tourist licences as a special inherited asset
When the inherited property is a holiday flat that has been operating on Booking.com, Airbnb or Vrbo, the heirs inherit not just a building but an operating business with regulatory obligations and a tourist licence registered with the regional government. The licence does not transfer automatically: the heirs must notify the regional authority of the change of ownership within thirty days of the inheritance becoming effective. A failure to notify can result in the cancellation of the licence and the loss of forward bookings. The detailed regional rules are covered in our article on tourist licences and inherited property in Spain.
For properties in regions with closed registration of new licences (most of central Málaga, the Balearic Islands, Barcelona), the existing licence may add 10–25% to the property’s value. Treating the licence as an inherited asset and transferring it correctly is therefore both a regulatory requirement and a material commercial decision. The thirty‑day deadline is short and is in addition to the six‑month inheritance tax deadline.
Inheriting with debts: benefit of inventory and renunciation
Not every Spanish inheritance is solvent. When the deceased’s debts exceed the asset values, accepting the inheritance unconditionally exposes the heirs to personal liability for the shortfall — Spanish law treats the estate as a single mass and the heir succeeds to the deceased’s position in full. The protections that exist must be specifically elected. Acceptance under benefit of inventory (beneficio de inventario) limits the heir’s liability to the value of the assets received. Renunciation (renuncia) walks away from the estate entirely; the share passes to the next in line.
A pre‑acceptance investigation of the estate is the right first step when there is any reason to suspect insolvency. The investigation covers Spanish bank accounts, Land Registry entries, cadastral records, tax authority records, community of owners records, and Mercantile Registry entries. Based on the investigation, the heirs decide between unconditional acceptance, acceptance under benefit of inventory, and renunciation. Each route has its own procedural and tax consequences and must be elected within strict time limits.
Coordination with home‑country inheritance tax
Spain has very few bilateral inheritance tax treaties (the most important is with France, 1963 with subsequent protocols). The UK, the US, the Netherlands and Germany have no bilateral inheritance tax treaty with Spain. For these countries, the avoidance of double taxation relies on unilateral credit mechanisms in each country. The Spanish unilateral credit (article 23 of the ISD Act) allows the Spanish‑resident heir to credit home‑country tax paid on the same assets. The home‑country credits work similarly in the reverse direction.
For typical Andalusian inheritances where the Spanish tax is near zero (due to the 99% regional reduction), the credit is not material in practice — the home‑country tax is the binding constraint. For inheritances where Spanish tax is substantial (more distant relatives, regions without strong reductions), the credit mechanisms must be applied carefully to avoid economic double taxation. The professional coordination between the Spanish lawyer and the home‑country adviser is essential for high‑value or complex files.
Selling an inherited property in Spain
Many international families eventually want to sell the Spanish property they have inherited. The Spanish capital gains tax (IRNR for non‑residents) on the sale is calculated on the difference between the sale price and the value declared in the inheritance, with various deductions for selling costs. For inherited properties this step‑up basis in value is favorable: it eliminates any capital gain accrued during the deceased’s lifetime. The trade‑off is that a low value declared for inheritance tax saves nothing if the regional reduction already eliminated the tax, and it generates a higher capital gain on the eventual sale. Our guide on selling inherited property in Spain covers this in detail.
The mechanics of the sale (3% retention by the buyer, IRNR filing within three months, plusvalía municipal, coordination with the home‑country capital gains tax) are well‑established but require professional handling. For non‑resident heirs the lawyer typically manages the entire sale process, including the post‑sale tax filings.
Multiple heirs and partition disputes
When several heirs jointly inherit, the file requires the unanimous agreement of all of them — the deed of acceptance must be signed by every heir. If one heir refuses to cooperate, the file blocks. The six‑month tax clock keeps running. The other heirs cannot register property, cannot release bank accounts, cannot sell. Spanish law provides two procedural tools to break deadlock: the notarial interpellation under article 1005 of the Civil Code (forces the silent heir to declare within thirty days whether they accept or renounce), and the judicial division of the estate (full court proceeding with a court‑appointed expert producing a partition project).
For families with any sign of disagreement, each side should have separate legal representation from the start — a single lawyer cannot ethically continue to act for both sides once a dispute crystallises. Early identification of the dispute risk and early appointment of separate advisers can save many months of subsequent procedural friction.
Estate planning during life: what foreign nationals in Spain should do now
For foreign nationals who own Spanish property or are otherwise resident in Spain, the most cost‑effective planning step is to make a Spanish will with a choice clause for the law of nationality, coordinated with any existing will in the home country. The cost is a single notarial appointment in Spain (around €60–€120), the protection is substantial. Without a Spanish will, the default rule applies the law of habitual residence — typically Spanish law for any long‑term resident — with the legítima governing the entire estate.
For larger or more complex estates, additional planning may include lifetime gifts to use cumulative thresholds (UK lifetime exemption, US annual exclusion, Spanish regional reductions), structured ownership of Spanish property (personal vs. company structures), use of foreign‑law devices (UK trusts with careful Spanish analysis), and coordination of the testamentary scheme between jurisdictions. Each step should be done with professional advice in both Spain and the home country.
Cost of a Spanish inheritance for an international family
The all‑in cost of a Spanish inheritance file for a foreign family is normally between €5,000 and €15,000 for a standard Andalusian property and bank account inheritance, including all professional fees, taxes and registration costs. This is a small fraction of the typical estate value and is dramatically less than it would have been before the regional inheritance tax reductions of 2019. The detailed breakdown is in our cost of a Spanish inheritance overview.
The professional fees (lawyer, accountant) are now the dominant component. Lawyer fees are typically 1.5–2.5% of the gross estate with a minimum of around €2,500–€4,000. Notarial fees are regulated by national tariffs and predictable. Land Registry fees are similar. Ancillary costs (apostilles, sworn translations, NIE applications) add a few hundred euros. The total is well‑aligned with the complexity and value of the file.
A timeline for the typical international inheritance
Week 1–2: instruct a Spanish lawyer, obtain the death certificate (Spanish or apostilled home‑country), arrange the NIE application for each heir (lawyer‑delegated route). Week 2–4: prepare the Spanish power of attorney, signed by each heir and apostilled. Week 4–8: the lawyer locates all Spanish assets and obtains the certificate of last will. Week 8–16: the lawyer drafts the deed of acceptance, calculates the inheritance tax with regional reductions, schedules the notarial appointment. Week 16–20: notarial deed signed, inheritance tax paid, Land Registry presentation. Week 20–26: Land Registry inscription completed, post‑inscription administrative steps. Total: four to six months for a standard file, within the six‑month tax deadline.
For complex files (disputes, insolvent estates, multiple Spanish regions) the timeline is longer and may require the six‑month extension. The earlier the lawyer is engaged, the more options remain on the table. Delays of two to three months between the death and the first contact with a Spanish lawyer are common for international families and typically cost the family the comfortable margin within the six‑month deadline.
Action steps for an international family at the moment of a Spanish inheritance
First and most important: contact a Spanish lawyer experienced in international inheritance work within the first week after the death. Second: obtain the death certificate (home‑country, with apostille and sworn translation) or the Spanish death certificate if the death occurred in Spain. Third: provide the lawyer with whatever information the family has about the deceased’s Spanish assets, even if fragmentary. Fourth: sign the power of attorney for each heir before a local notary, with apostille. Fifth: cooperate with the lawyer’s asset‑location and document‑preparation steps. Sixth: attend the (remote) review of the deed before signature and approve the final terms. Seventh: receive the post‑inscription documents and integrate the inherited assets into the heir’s personal portfolio. For an initial consultation, contact our team.
The combination of correct legal advice, prompt action and proper procedural execution turns what feels like an overwhelming cross‑border problem into a manageable file that resolves within six months at modest cost. The investment in qualified professional advice from the first week is the single best decision the family will make in the entire process.
