Wills in Spain for Expats: 2026 Legal Guide

For expats with property, bank accounts or other assets here, understanding wills in Spain is an important part of cross-border estate planning. A Spanish will is not mandatory merely because you own an asset in Spain, but a properly coordinated will can make the Spanish administration of the estate more efficient.

The right structure depends on nationality, habitual residence, family circumstances, assets and any existing wills. The aim is to align the Spanish document with the wider estate plan—not to create a second will that conflicts with it.

When a Spanish Will Can Help With Assets in Spain

A foreign will may be valid in Spain, but using it can require probate evidence, an apostille or legalisation and a sworn translation. Whether a separate Spanish will is worthwhile depends on the estate. For some clients it simplifies the local process; for others, careful coordination of the existing will is the better answer.

The decision should follow a review of the documents and assets rather than a fixed rule that every foreign owner needs a Spanish will.

When considering how to manage your Spanish assets, the difference between using a local will and a foreign one is stark. Here’s a quick comparison to make the choice clear.

Spanish Will vs Foreign Will for Spanish Assets

Understanding Spanish Forced Heirship Rules

If you’re from the UK, the US, or another common law country, Spain’s forced heirship system will likely be your biggest surprise. We call it the legítima. It’s a default rule that can feel incredibly restrictive if you’re used to leaving your assets to whomever you wish.

Under the Spanish Civil Code, a large chunk of your estate is automatically reserved for specific relatives, known as “forced heirs” (herederos forzosos). You simply cannot give this portion to anyone else in your will. The system is meant to protect immediate family, but it often clashes directly with the intentions of expat clients — particularly those with blended families or a surviving spouse they want to protect.

Who Are the Forced Heirs?

The law sets out a very clear pecking order. It’s important to know who falls into this category, as it dictates how your estate gets split if Spanish law applies.

• Children and descendants: Under the common Civil Code, they usually have the strongest reserved rights and come first in the order of succession.
• Parents and ascendants: They can become relevant if there are no descendants.
• Surviving spouse: The spouse often has usufruct rights rather than a simple outright share, but the exact outcome depends on the applicable law and family structure.

This creates situations our clients genuinely don’t see coming. We’ve worked with couples who assumed their Spanish apartment would pass smoothly to the surviving spouse — only to discover that, under default Spanish rules, adult children from a previous marriage were entitled to a forced share of that property. If you’re also planning to buy property in Spain, understanding these rules before you purchase is far less costly than dealing with them afterwards.

The Three Thirds Rule Explained

Think of your estate as a cake sliced into three equal pieces. This is the core of Spanish inheritance and where it diverges completely from common law.

1. 1. The Strict Legitime (Legítima Estricta): This first third is non-negotiable. It must be divided equally among your children. You have zero say in the matter.
2. 2. The Improvement Third (Tercio de Mejora): This second third also has to go to your children or their descendants, but here you have some flexibility. You can “improve” one child’s inheritance by giving them the whole third, or split it unevenly.
3. 3. The Free Disposal Third (Tercio de Libre Disposición): This is the only part you truly control. You can leave this final third to anyone — a friend, your spouse, a charity, or even give it as an extra portion to one of your children.

In practical terms, if Spanish law applies to your estate and you have children, two-thirds of everything you own in Spain is already spoken for by law. The exact result depends on the family structure and the law that ultimately applies to the succession — which is precisely why this needs to be assessed properly before anything is drafted.

How to Regain Control of Your Estate

Where the Regulation applies, nationality may provide a choice-of-law option. The EU Succession Regulation (No 650/2012), also known as Brussels IV, is the key. It allows a person to choose the law of a state whose nationality they possess to govern their succession as a whole.

By adding a properly drafted “choice of law” clause to your Spanish will, you can ask for the law of your nationality to apply to your succession. That often avoids the default Spanish forced-heirship outcome — but the clause still needs to be coordinated with your wider estate and tax planning in Spain. It is not a one-size-fits-all solution.

Without a valid election, the general rule is the law of habitual residence at death, subject to the Regulation’s exceptions and scope. If Spanish law applies, forced-heirship rules may affect the result. This is why the clause and the wider circumstances must be analysed together.

Choosing the Right Type of Spanish Will

When it comes to making a will in Spain, you have a few options. But for nearly every expat we work with, only one really makes sense: the Open Will. Its security, simplicity, and official registration make it the undisputed best choice. Other types of wills exist, but they often create more problems than they solve.

The Open Will (Testamento Abierto): Usually the Most Practical Option

The Open Will, or Testamento Abierto, is the most common and secure way to formalise your wishes in Spain. It’s the only type of will we prepare for our clients, and for good reason.

The will is signed before a public notary after being drafted by a legal expert. The notary verifies identity, capacity, and legal compliance. The original is held securely by the notary — and crucially, its existence is registered with Spain’s Central Registry of Last Wills (Registro de Actos de Última Voluntad). This means your will can never be lost, hidden, or overlooked. When the time comes, your heirs locate it with a single official search.

The Problematic Alternatives

While technically legal, the other types of Spanish wills are a minefield of risk, cost, and delay for the people you leave behind. We almost never recommend them.

• The Closed Will (Testamento Cerrado): Submitted to a notary in a sealed envelope. What it says remains unknown until death — at which point it triggers a mandatory court process just to be opened and validated. Families face months of delays and court costs before the estate can even begin to be administered.
• The Holographic Will (Testamento Ológrafo): Written entirely by hand, with no notary. Your heirs must prove your handwriting, obtain judicial validation within five years, and withstand any legal challenges. We’ve seen families spend more on the validation process than the testator saved by writing the will themselves.

An Open Will is often practical for Spanish assets, but the right instrument depends on the wider estate, family structure and any foreign will already in force.

How Spanish Inheritance Tax Works Across Regions

Spain’s inheritance tax, the Impuesto sobre Sucesiones y Donaciones, is not one single system. It’s a patchwork of rules set by the state and the 17 autonomous communities. The tax bill your heirs face depends entirely on where your assets are — and the difference between regions can be enormous.

State-level rates start at 7.65% and climb to 34%. But that’s just the baseline. The autonomous communities apply their own reliefs (bonificaciones) that can slash the final bill to almost nothing — or leave it largely intact. What this means in practice is that two families inheriting estates of identical value can face tax bills that differ by tens of thousands of euros, simply because of where the property sits. For a broader view of how Spain taxes residents and non-residents alike, see our guide to taxes for expats in Spain.

The Impact of Regional Tax Differences

We see the consequences of this directly. Heirs in regions with generous reliefs can inherit large estates with minimal tax exposure. Heirs in regions without those reliefs can face five-figure tax bills on properties that were never intended to generate a tax burden. This is why we always review the regional tax position alongside the will itself — treating them as separate exercises routinely costs families money they didn’t have to spend.

Rules for Non-Resident Heirs

What happens if your heirs don’t live in Spain? For years, non-residents were forced to pay the higher state-level tax regardless of where the assets were. The European Court of Justice correctly ruled this was discriminatory.

A landmark decision now lets non-resident EU/EEA citizens use the more favourable tax laws of the autonomous community where the assets are located. This opens the door to significantly better outcomes for non-resident heirs — but the result still depends on the region, the family relationship, and how the estate is structured.

It’s not just about who gets what, but about how much they actually keep. If your heirs may eventually sell the inherited property, it’s also worth understanding capital gains tax in Spain and how it interacts with your succession plan.

What Working With Us Looks Like

Wills in Spain are not something you need to manage alone. The legal decisions involved — particularly around choice of law, family structure, and regional tax — require professional input. What we provide is a coordinated process that takes care of every element, so that nothing gets missed and nothing comes back to hurt your family later.

It starts with a conversation about your situation: what you own in Spain, who you want to benefit, and how that fits with any existing estate planning you have in your home country. From there, we handle the legal analysis, the drafting — including a bilingual version so you understand every clause — the coordination with a public notary, and the registration with Spain’s Central Registry of Last Wills. By the end of the process, your will is legally sound, properly registered, and impossible to overlook.

The clause that protects your freedom to distribute your estate as you choose, the language that prevents your Spanish will from inadvertently cancelling your home country will, the coordination with your regional inheritance tax position — these are the details that matter and the details we are paid to get right.

When a Spanish will needs individual review

The answers depend on the full estate and family position. Tax is a separate part of the analysis; see our guide to inheritance tax in Spain. Legal Fournier’s wills and inheritance service covers coordinated planning and administration.

Your Spanish Will Questions, Answered

Do I Really Need a Spanish Will for My Spanish Property?

Legally, no. Practically, the families who rely solely on a foreign will consistently face the most difficult and expensive probate processes we see. Sworn translations, apostilles, and notary procedures that drag on for months — sometimes well over a year — and cost thousands of euros in legal fees. A proper Spanish will makes the process far faster and far cheaper for the people you leave behind.

Can My Spouse and I Make a Joint Will?

No. Spanish law is very clear on this: wills are strictly individual. Each person must make their own separate will before a notary. Even if your wishes are identical, you will each sign your own Testamento Abierto. We can draft both wills together so they are fully coordinated and consistent with your shared estate plan.

What Happens If I Die in Spain With No Will at All?

If you die intestate in Spain, the law of your habitual residence determines how your estate is divided. If that’s Spain, rigid succession rules apply: children and their descendants come first, followed by parents or ascendants if there are no children. As for the surviving spouse — the position is more nuanced than most people expect. Under Spanish intestate law, the spouse does not inherit ownership rights alongside children or parents, but does retain usufruct rights over a portion of the estate: one-third when children survive, one-half when only parents survive. Full ownership only passes to the spouse when there are no living descendants or ascendants.

We’ve seen cases where a surviving spouse ends up with only a usufruct right while the deceased’s elderly parents — or adult children from a previous relationship — inherit the assets outright. On top of that, the heirs face a complex legal procedure called a declaración de herederos abintestato just to be formally recognised — adding more time and cost to an already difficult situation.

A coordinated will can record your wishes and reduce the risk of an unintended intestate outcome, subject to the law that ultimately governs the succession.

Planning your estate across borders raises questions that don’t have generic answers — they depend on your nationality, your family structure, your assets in Spain, and your wider succession plan. Our firm specialises in wills and inheritance services for expats across Spain. We work through these questions with you directly, so that nothing is left to chance.
