Is a Spanish Will Valid in the UK? Cross-Border Estate Planning Explained

The worry for anyone with a Spanish will and UK assets is whether it works back home — a Spanish will can be valid in the UK, but only if it is drafted and coordinated so it does not clash with, or accidentally revoke, your UK will.

Last updated: March 2026

If you own property in Spain and have ties to the United Kingdom, one of the most important — and most commonly overlooked — aspects of your estate planning is whether your Spanish will is valid in the UK, and vice versa. The answer is nuanced, and getting it wrong can lead to costly delays, family disputes, and unintended tax consequences.

The Short Answer

A Spanish will can be valid in the UK, but it is not automatically recognised. For it to be given effect, it must go through a process of recognition or be presented alongside a UK grant of probate. In practice, most cross-border estate planning experts recommend having separate wills for each jurisdiction — one for your Spanish assets and one for your UK assets.

Brussels IV Regulation (EU Succession Regulation 650/2012)

The Brussels IV Regulation is the EU framework that determines which country’s law applies to a cross-border succession. Key points:

• Default rule: The law of the country where the deceased was habitually resident at the time of death applies to the entire estate.
• Choice of law: You can choose the law of your nationality to govern your succession, regardless of where you live. This is done through a clause in your will (a professio juris).
• The UK is not bound by Brussels IV. Since the UK never opted into the regulation (even before Brexit), UK courts apply their own conflict-of-laws rules. However, Spain does apply Brussels IV, which means Spanish authorities will follow its rules when dealing with your Spanish assets.

What This Means in Practice

If you are a British national living in Spain:

• Without a choice-of-law clause, Spanish law (including forced heirship rules) will apply to your entire worldwide estate under Brussels IV.
• With a choice-of-law clause selecting English/Welsh or Scots law, you can avoid forced heirship and distribute your estate according to your wishes.
• UK courts will apply English conflict-of-laws principles, which generally say that immovable property (land, houses) is governed by the law of the country where it is located, and movable property (bank accounts, investments) is governed by the law of the deceased’s domicile.

When Do You Need Separate Wills?

In almost all cases involving assets in both Spain and the UK, separate wills are recommended. Here is why:

• Speed: A Spanish will registered with the Registro General de Actos de Última Voluntad can be processed quickly in Spain without waiting for UK probate.
• Language: Spanish authorities require the will to be in Spanish (or officially translated). A UK will must go through translation and apostille, adding weeks or months.
• Legal formalities: Spanish wills follow specific notarial requirements. A UK will that does not meet these may be challenged.
• Avoiding revocation: A poorly drafted second will can accidentally revoke the first. Each will must contain a clause stating it applies only to assets in that jurisdiction and does not revoke wills made in other countries.

Comparison: Spanish Will vs UK Will

Feature	Spanish Will	UK Will
Creation	Executed before a Spanish notary (notario)	Signed with two witnesses (England/Wales)
Registration	Automatically registered with the Central Registry of Wills	Optional registration with the Probate Registry
Language	Spanish (interpreter present if needed)	English
Forced heirship	Applies under Spanish law (children receive at least ⅔ of estate) — can be avoided with choice-of-law clause	No forced heirship in England/Wales. Scots law has limited legal rights
Probate process	No formal “probate” — heirs accept inheritance before a notary	Grant of probate required from the High Court
Inheritance tax	Spanish succession tax (Impuesto sobre Sucesiones y Donaciones) — rates and allowances vary by region	UK Inheritance Tax at 40% on estates over £325,000 (or £500,000 with residence nil-rate band)
Typical cost	máximo 1.200€+IVA (testamento individual) o 900€+IVA por persona (pareja); €1,000–€5,000+ for inheritance processing	£150–£500 for the will; probate fees vary
Recognition abroad	Recognised in the UK via apostille and sworn translation, but may require separate UK probate	Recognised in Spain but requires apostille, sworn translation, and may need additional notarial process

Probate in Both Jurisdictions

When someone with assets in both Spain and the UK passes away, two parallel processes typically occur:

In Spain

1. Obtain the death certificate and register it with the Spanish Civil Registry
2. Request the Certificado de Últimas Voluntades (certificate confirming whether a Spanish will exists) — available 15 working days after death
3. If a Spanish will exists, the named heirs attend the notary to accept or renounce the inheritance
4. Pay Spanish succession tax within six months (extendable to 12 months with a request filed in the first five months)
5. Transfer property titles at the Land Registry

In the UK

1. Register the death and obtain the death certificate
2. Apply for a Grant of Probate (or Letters of Administration if there is no will)
3. Identify and value all UK assets
4. Pay UK Inheritance Tax if applicable
5. Distribute assets according to the will (or intestacy rules)

These processes run independently. There is no single authority that oversees both. Co-ordination between your Spanish and UK lawyers is essential.

Common Mistakes in Cross-Border Estate Planning

1. Having only one will. A UK will that covers “all my worldwide assets” is technically valid in Spain, but enforcing it is slow, expensive, and uncertain.
2. Accidentally revoking the other will. Standard boilerplate in UK wills (“I revoke all previous wills”) will revoke your Spanish will. Each will must explicitly state it only covers assets in that jurisdiction.
3. Ignoring forced heirship. Without a choice-of-law clause, Spanish forced heirship rules apply. Your children are entitled to at least two-thirds of your estate under Spanish law, regardless of what your will says.
4. Forgetting about the tax overlap. Your estate may face both Spanish succession tax and UK inheritance tax. The UK-Spain double taxation treaty on estates helps, but it must be actively claimed.
5. Not updating after life changes. Marriage, divorce, the birth of children, or acquiring new assets all require will updates — in both jurisdictions.
6. Joint wills. These are not recognised under Spanish law. Each spouse must have their own separate will.
7. Not informing family. Your heirs need to know that two wills exist and where to find them. Spanish wills are registered centrally; UK wills may be held by a solicitor or at home.

Practical Steps for Cross-Border Estate Planning

1. Make two wills. One Spanish will (before a notary in Spain) covering your Spanish property, bank accounts, and other Spanish assets. One UK will covering your UK assets.
2. Include a choice-of-law clause. In your Spanish will, specify that you choose English/Welsh (or Scots) law to govern your succession. This avoids forced heirship.
3. Include a non-revocation clause. Each will should state: “This will applies only to my assets in [Spain/the UK] and does not revoke any will I have made in [the UK/Spain].”
4. Appoint appropriate executors. Your Spanish will should name someone who can act in Spain (or appoint a power of attorney for a Spanish lawyer). Your UK will should name UK-based executors.
5. Review regularly. At minimum, review both wills every three years or after any major life event.
6. Co-ordinate with specialists. Use lawyers who understand both jurisdictions. A Spanish lawyer unfamiliar with UK probate (or vice versa) may miss critical cross-border issues.

Is a UK Will Valid in Spain?

Similarly, a will made in England under English formalities can be valid in Spain for the purposes of disposing of Spanish assets — but it will require careful handling. The Spanish inheritance process involves presenting the will before a Spanish notary, and the notary will need:

• The original will or a certified copy with Apostille
• A sworn Spanish translation (traducción jurada)
• A certificate from the Registro de Actos de Última Voluntad (Spanish Wills Registry) confirming no later Spanish will exists
• A certificate from the UK Probate Registry if probate has been granted in England

Critical Rule: Avoid Accidental Revocation

The single most dangerous mistake in dual-will planning is one will accidentally revoking the other. Standard will-drafting practice in England includes a clause such as “I revoke all previous wills and testamentary dispositions.” If your English solicitor includes this clause without limiting it to UK assets, it will revoke your Spanish will.

Both wills must contain carefully worded clauses specifying:

• The geographic or asset scope of each will (e.g., “This will applies only to my assets located in Spain”)
• That the will does not revoke wills made in other jurisdictions governing assets in those jurisdictions
