Spanish Inheritance from a Non-Resident Parent: International Heirs and the Spanish Procedure
When a non-resident parent (UK, US, German, etc.) owns Spanish property and passes away, the international heirs face a Spanish inheritance procedure that requires specific handling. This guide explains the procedural framework, the application of regional ISD reductions to non-resident deceased and non-resident heirs (post-2018 ECJ rulings), the six-month deadline management, and the practical steps. A dedicated inheritance lawyer coordinates the file.
The scenario: non-resident parent with Spanish property
A typical scenario: UK parent owned a Marbella apartment for years as second home; parent dies in UK; UK heirs (children) inherit; the Spanish apartment is part of the inheritance and must be processed through the Spanish inheritance procedure. The parent was not Spanish resident; the heirs are not Spanish resident; the Spanish-situs property is the only Spanish connection.
The Spanish inheritance procedure applies to the Spanish-situs property regardless of the residence of either the deceased or the heirs. The procedure includes: obtaining death certificate (UK death certificate apostilled and translated); searching the Spanish Registry of Last Wills; preparing notarial deed of acceptance; filing the Spanish ISD; registering the property at the Land Registry.
The procedural framework is the same as for Spanish-resident deceased and heirs, but with the additional considerations of international documentation (apostille, translation), NIE for heirs, and remote handling through lawyer with power of attorney. The Spanish-side procedure can be handled entirely remotely.
Regional ISD reductions apply to non-residents
Post-2018 European Court of Justice rulings, the Spanish regional ISD reductions apply equally to non-resident heirs and to inheritances from non-resident deceased. The discrimination against non-residents was held contrary to EU law and Spain amended the legislation. For Andalusian properties inherited by international heirs, the 99% reduction applies fully.
For a UK-resident heir inheriting an Andalusian apartment from a UK-resident parent, the Spanish ISD is typically a few hundred euros (with the 99% regional reduction). The Spanish-side tax cost is minimal. The primary tax cost is on the UK side (UK IHT on the worldwide estate of the UK-domiciled parent).
The application of the regional reduction depends on which region is the relevant region. For non-resident deceased, the relevant region is typically the region where the most valuable Spanish asset is located. For a Marbella apartment as only Spanish asset, the relevant region is Andalusia, and the Andalusian reductions apply.
The six-month deadline management
The six-month Spanish ISD deadline runs from the date of death, regardless of where the heirs are or what other procedures are pending. The deadline is strict; surcharges of 5-20% apply for late filing plus interest. For international families with UK or US probate to manage in parallel, the Spanish six-month deadline often forces decoupling of procedures.
The standard approach: handle the Spanish file independently of the foreign probate, building it from the death certificate, the will (UK or Spanish), and the heirs' identification documents. The Spanish lawyer manages the file under power of attorney from the heirs. The foreign probate continues in parallel without affecting the Spanish timeline.
When the file genuinely cannot complete in six months (heirs unknown, will dispute, complex valuation), the six-month extension can be requested within the first five months. The extension provides another six months and is normally granted for international cases when properly applied for.
NIE for international heirs
Each international heir needs a Spanish NIE before signing the deed of acceptance. The NIE can be obtained through Spanish consulate in the heir's country of residence, in person at Spanish Foreigners Office, or through the Spanish lawyer with power of attorney. The lawyer-delegated route is typically fastest (3-4 weeks) and is the standard for international cases.
The NIE application should be initiated immediately after the death of the parent (within the first 1-2 weeks of the procedure). Delays in obtaining NIE can cause the entire timeline to slip toward the six-month deadline. Early action is essential.
Power of attorney for remote handling
For international heirs unable to travel to Spain for the inheritance procedure, the power of attorney enables the Spanish lawyer to act on the heir's behalf. The power authorizes the lawyer to: search registries; sign the notarial deed of acceptance; file and pay ISD; register the property at the Land Registry; manage related procedural acts.
The power is signed before a notary in the heir's country of residence (with apostille under Hague Convention), or at a Spanish consulate (no apostille needed because already Spanish format). The power must specifically authorize the inheritance-related acts; a general power may not be sufficient.
Once the power is in the Spanish lawyer's hands, the entire Spanish procedure can be completed without the heir traveling to Spain. The deed of acceptance is signed by the lawyer; the tax is paid; the property is registered. The heir receives the final documentation by email.
Document apostille and translation
The international documents required for the Spanish file (death certificate, will if foreign, marriage certificate if relevant, certificates of heirship) typically need apostille under the Hague Convention (or consular legalization for non-Hague countries) and sworn translation into Spanish.
Apostille is handled in the country of origin (FCDO in UK, state Secretary in US, equivalent in other countries). Sworn translation is done by translators authorized by the Spanish Ministry of Foreign Affairs. The timeline: 1-3 weeks for apostille + 1-2 weeks for translation, totaling 3-5 weeks for the document preparation.
The lawyer typically coordinates the apostille and translation process or directs the heirs on the procedure. Starting the document preparation in week one of the procedure is essential to maintain the timeline toward the six-month deadline.
Coordination with home-country probate
The Spanish procedure runs in parallel with the home-country probate. For UK estates, UK probate handles UK assets; the Spanish procedure handles Spanish assets. Each is independent. The home-country solicitor coordinates with the Spanish lawyer to share documents (death certificate, will) and to coordinate on the inheritance tax position (Spanish ISD paid creditable against UK IHT, etc.).
The home-country probate may take longer than the Spanish six-month deadline (UK probate can take 4-16 weeks or more; US probate often longer). The Spanish procedure should not wait for the home-country probate to complete. The Spanish procedure proceeds independently.
The home-country IHT filing (UK IHT400 within 12 months; equivalent in other countries) includes the Spanish property in the worldwide estate (for UK-domiciled deceased). The Spanish ISD paid is creditable against the UK IHT under unilateral relief. The professional coordination ensures the credit is properly claimed.
Post-inheritance ongoing management
After the Spanish inheritance is completed and the property is registered in the heirs' names, the ongoing management includes: annual IRNR for non-resident heirs (imputed income or actual rental income); IBI municipal tax; community fees; eventual decision on sale, rental, or continued use as second home.
For international heirs with the property as second home, the ongoing management is similar to any non-resident property ownership. For heirs planning to sell, the sale procedure follows the standard non-resident sale framework with capital gains tax considerations.
Action steps
First: contact Spanish inheritance lawyer immediately after parent's death. Second: obtain death certificate with apostille. Third: gather will and other documentation. Fourth: arrange NIE through lawyer-delegated route for each heir. Fifth: sign power of attorney before local notary with apostille. Sixth: lawyer manages Spanish procedure under power. Seventh: complete inheritance within six months; pay ISD. Eighth: integrate inherited property into ongoing financial management. For consultation, contact our team.
The Spanish inheritance procedure for international heirs of non-resident parents is well-established and tax-favorable due to regional reductions. With professional handling, the entire procedure can be completed remotely within the six-month deadline at modest cost.
