Quick answer: To resolve a Spanish inheritance dispute, work in order: establish which national law applies, obtain a full inventory of the estate, attempt a negotiated partition, and — only if the heirs deadlock — ask the court for a judicial partition, while preserving any right to challenge the will or a disinheritance within the legal time limits. A negotiated settlement is almost always faster and cheaper than litigation, but the threat of court is often what makes settlement possible.
How to resolve a Spanish inheritance dispute, step by step
- Establish which law applies. Under Brussels IV (EU Regulation 650/2012) a foreign national may have validly elected the law of their nationality. That election decides whether Spanish forced-heirship applies at all — so it is the first question, not an afterthought.
- Obtain a full estate inventory and title. Identify every asset and debt — Spanish and foreign property, accounts, business interests — with the deeds, the death certificate, the Last Wills certificate (Certificado de Últimas Voluntades) and the will. Hidden or undeclared assets are a frequent cause of dispute.
- Attempt a negotiated partition. The heirs (and any usufructuary spouse) agree a partition deed (cuaderno particional) before a notary. Most disputes should be resolved here, with legal advice on each heir’s legítima entitlement.
- If you deadlock, request a judicial partition. Any heir can ask the court for a división judicial de patrimonios. A court-appointed contador-partidor prepares a partition proposal that the court can approve, modify or reject after hearing objections. Expect roughly 18 months to 3 years — longer where there are business or foreign assets.
- Challenge the will or disinheritance if there are grounds. If a forced heir was improperly excluded, or the will’s validity is in doubt, raise it within the applicable limitation period. Do not let deadlines lapse while negotiating — preserve the claim in parallel.
Deadlines you cannot miss
Spanish inheritance tax must generally be filed within 6 months of death (an extension can be requested), and that clock runs regardless of whether the heirs are still arguing. Limitation periods to contest a will or a partition are case-specific and can be shorter than people assume, which is why a dispute should be assessed early — not after the estate has dragged on for years.

Frequently asked questions
How long does a judicial partition take in Spain?
Typically 18 months to 3 years, and longer where the estate includes business interests or foreign assets.
What is a contador-partidor?
A court-appointed expert who prepares a partition proposal in a judicial partition; the court can approve, modify or reject it after hearing the heirs’ objections.
Can heirs settle an inheritance dispute without going to court?
Yes, and most should. The heirs can agree a partition deed (cuaderno particional) before a notary with legal advice; court is the fallback when they deadlock.
What is the deadline to pay Spanish inheritance tax?
Generally 6 months from death, with the possibility of requesting an extension; the deadline runs even if the heirs are still in dispute.
Can I contest a Spanish will?
Yes, if there are grounds such as improper disinheritance of a forced heir or doubts about the will’s validity, but limitation periods apply and can be short, so seek advice early.
