A Spanish will is a notarial document signed in Spain that allows you to organise how your assets located in Spain should be dealt with on death.
Important: Spanish succession follows two distinct paths depending on whether the deceased left a valid will (testate) or not (intestate). The intestate path requires a Declaration of Intestate Heirs (Declaración de Herederos Abintestato) — a step not needed when a will exists. Learn more about the succession process →
For international families, the key is coordination:
- avoiding conflicts between wills in different countries,
- reducing delays for heirs in Spain,
- and ensuring the applicable succession law is clear under EU cross-border rules.
Quick answers
- Do I need a Spanish will if I already have a foreign will? Often yes — a Spain-only will can reduce delays for heirs when there are assets in Spain.
- Does a Spanish will cover worldwide assets? It can be drafted as Spain-only to avoid conflicts with foreign wills.
- International families: the goal is clean coordination so heirs do not face unnecessary notary/registry/bank friction in Spain.
- Best fit: non-residents who own Spanish property or bank accounts and want smoother succession administration.
Legal basis (Spain)
A Spanish will (testamento) is a notarial instrument governed primarily by:
- the Spanish Civil Code (Código Civil) rules on wills and succession, and
- where applicable, the EU cross-border succession framework for international estates.
For international families, the key is that the will must be valid under Spanish formalities (notarial execution) and aligned with cross-border planning where assets and heirs are outside Spain.
Official sources (primary)
- Spanish Civil Code (Código Civil) — BOE
- EU Regulation 650/2012 (Succession / “Brussels IV”) — EUR-Lex
Who this is most relevant for
This is especially relevant if you:
- own Spanish property (home, holiday home, investment property)
- have Spanish bank accounts or investments
- have heirs in different countries (UK / US / EU / Non-EU)
- want to reduce the risk of conflicting wills and administrative delays in Spain
What a Spanish will typically covers
A Spanish notarial will can be drafted to cover:
- Spanish real estate (sale, inheritance, Land Registry steps)
- Spanish bank accounts and balances
- Spanish shares or local investments
- Spanish movable assets located in Spain
- instructions for practical administration in Spain (where appropriate)
Key drafting principle: scope can be limited to Spain-only assets, so your foreign will continues to govern the rest of your estate.
Spain-only scope (why it reduces conflict)
A common structure for international families is a Spain-only will, drafted so it:
- applies only to assets located in Spain, and
- does not revoke the foreign will beyond Spain.
This is often used to reduce administrative friction for heirs with Spanish property or accounts.
Cross-border coordination: the practical structure that avoids conflicts
For international families, the clean structure is usually:
1) Foreign will covering worldwide assets (or home-country assets)
2) Spanish will covering Spain-only assets
3) Clear wording so the Spanish will does not revoke the foreign will beyond Spain
This reduces the risk of:
- accidental revocation,
- duplicate administration,
- delays for heirs,
- and contradictory instructions across jurisdictions.
Applicable law and EU cross-border succession rules (high-level)
EU cross-border succession rules aim to treat a cross-border estate coherently, generally under a single applicable law, and allow (in many situations) a person to choose the law of their nationality to govern their succession.
When this becomes critical (typical scenarios)
This matters most when:
- the deceased had multiple national connections (nationality, residence, assets), and
- heirs need clarity on which succession law governs the Spanish part of the estate.
This becomes critical when:
- a family expects English/Welsh style freedom of testamentary disposition,
- but assets are located in Spain where civil law constraints may otherwise apply.
Practical note: coordination is legal drafting + evidence + consistency, not just “having two wills”.
Common mistakes we see (that create delays or disputes)
Common issues include:
- using a foreign will in Spain without Spain-specific drafting and administration planning
- unintentionally revoking previous wills through generic revocation wording
- failing to define the territorial scope (Spain-only vs worldwide)
- inconsistent naming of heirs/beneficiaries across documents
- not aligning the will strategy with marital regime / property ownership structure
Documents you typically need (typical list)
Exact requirements vary by notary and the client’s circumstances, but international clients commonly prepare:
- passport / ID (and details for the notary file)
- civil status (married / divorced / widowed) and relevant supporting documents
- heir details (full names, dates of birth, relationship)
- Spanish asset overview (property, bank accounts, shareholdings, etc.)
- property details where applicable (title deed data and/or Land Registry references)
- coordination notes if you already have a foreign will (so both instruments do not conflict)
If you want the Spanish will to coordinate cleanly with your foreign estate plan, the drafting should be aligned before signing to avoid contradictions and administrative friction for heirs.
How the process works in Spain (typical)
1) confirm the asset map in Spain (property, accounts, ownership structure)
2) decide whether the Spanish will is Spain-only and how it coordinates with the foreign will
3) prepare a notary-ready Spanish will
4) execute before a Spanish notary
5) store certified copies and record practical instructions for heirs

Quick Answer — International Wills, Professio Juris and Estate Planning in Spain
Many expatriates assume that their existing UK, US, Canadian, Irish or Australian Will automatically solves their succession planning in Spain. In reality, cross-border estates require careful coordination.
Under EU Regulation 650/2012 (Brussels IV), the law governing your succession is generally the law of your habitual residence at death. However, a foreign national may often make a Professio Juris election in their Will, choosing instead the law of their nationality to govern their succession.
This can be extremely important because Spanish succession law includes forced heirship rules (legítima), which may differ significantly from the testamentary freedom available in many common-law jurisdictions.
At CostaLuz Lawyers, we focus on the harmonisation of international Wills, ensuring that Spanish and foreign Wills work together as part of a single estate plan and that any Professio Juris election is properly drafted and legally effective.

Frequently Asked Questions
Is my foreign Will valid in Spain?
In principle, yes. A foreign Will can be recognised and enforced in Spain provided it is valid under the law of the country where it was executed and complies with the relevant international formalities. However, legal validity and practical efficiency are two different things. While a foreign Will may be perfectly valid, relying exclusively on it can significantly complicate the Spanish probate process. Heirs may face additional legalisation and apostille requirements, certified translations, foreign probate proceedings that must first be completed before Spanish assets can be dealt with, increased legal costs, and delays that can extend the inheritance process by many months. Under EU Regulation 650/2012 (Brussels IV), the law governing succession may automatically become the law of habitual residence at the time of death — meaning a foreign national resident in Spain could unexpectedly find Spanish succession law applying unless proper planning has been undertaken.
Why do lawyers recommend a separate Spanish Will for Spanish assets?
A properly drafted Spanish Will can save heirs considerable time, expense, and stress. The purpose is not to replace your existing Will in your home country but to create a complementary document dealing exclusively with assets located in Spain — property, bank accounts, investments, vehicles. This allows the Spanish inheritance process to proceed independently of probate proceedings abroad. At CostaLuz Lawyers, our focus is on international Will harmonisation. We review existing Wills and draft Spanish Wills that do not accidentally revoke foreign Wills, respect the overall estate planning strategy, avoid conflicting dispositions, facilitate probate in multiple jurisdictions, and reflect the client’s wishes consistently across all countries where assets are held. A properly drafted Spanish Will also provides an opportunity to incorporate a Professio Juris clause where appropriate.
What is harmonisation in international Wills and why is it important under EU law?
Harmonisation is the process of coordinating all estate planning documents worldwide so they work together as part of a single coherent succession strategy. Under EU Regulation 650/2012 (Brussels IV), the default rule is that the law governing a person’s succession is generally the law of the country where they are habitually resident at death. The Regulation also introduced the Professio Juris — an express election made in a Will whereby a person chooses the law of their nationality to govern their succession. This can be extremely important because Spanish succession law contains forced heirship provisions (legítima) which may differ significantly from the inheritance freedom available in many common-law jurisdictions. Without careful planning, a foreign national living in Spain may unintentionally become subject to inheritance rules that do not reflect their wishes. At CostaLuz Lawyers, we have spent decades advising international families and regularly review existing Wills, prepare Spanish Wills, incorporate appropriate Professio Juris clauses, and coordinate cross-border estate plans.
