Inheritance Rights of a Surviving Spouse in Spain: The Expat Guide

In brief: Under Spanish law, a surviving spouse does not automatically inherit everything. Spanish succession law reserves a portion of the estate for children, and the spouse typically receives usufruct — the right to use and enjoy assets — rather than full ownership. For expat couples in Spain, the rules vary depending on where you are resident, your nationality, and whether a will exists. This guide explains the essentials.


The Assumption That Catches Expats Off Guard

Many expat couples in Spain assume that if one of them dies, the other automatically inherits everything — just as they might expect in the UK, Australia, or the United States. In Spain, this assumption is wrong.

Spanish inheritance law is built around the concept of forced heirship (legítima). A significant portion of any estate is legally reserved for direct descendants — children and grandchildren — regardless of what a will says. The surviving spouse has protected rights too, but they are more limited than most expats expect.

Understanding this before a death occurs — not after — is the difference between a smooth transition and a painful, expensive legal dispute.


What Does a Surviving Spouse Inherit Under Spanish Law?

Spanish law distinguishes between two types of inheritance rights for a surviving spouse:

Usufruct (The Default Position)

Under Spanish common law (derecho común), the surviving spouse has the right of usufruct over the tercio de mejora — one third of the estate reserved as an improvement share. This means the spouse can use and benefit from those assets (live in the property, receive rental income) but does not own them outright. The underlying ownership passes to the children.

In practice, if a married couple own a home in Spain and one spouse dies leaving children:

This is often a shock for expat couples who expected the survivor to have full control.

The Legítima (Forced Shares)

Spanish law divides the estate into three equal thirds (tercios):

Tercio Who receives it
Tercio de legítima estricta Must go to direct descendants (children/grandchildren) — cannot be changed by will
Tercio de mejora Must go to direct descendants, but the deceased can choose which ones
Tercio de libre disposición Free to leave to anyone — including the surviving spouse

The surviving spouse is not a forced heir under Spanish law (unlike children), but has the usufruct right over the tercio de mejora by default. If there are no children, the surviving spouse has stronger rights — including potentially inheriting the entire estate.


With a Will vs Without a Will

If There Is a Will

A will allows the deceased to maximise the surviving spouse's position — within the limits of the legítima. The most common strategy for married couples with children is:

With careful drafting, a surviving spouse in Spain can end up with a combination of full ownership (one third) and usufruct over the family home, which in practice means continued use and occupation. But it requires an explicit will — without one, the default rules apply, and the outcome may be significantly less favourable.

Without a Will (Intestate Succession)

If a person dies without a will in Spain, the intestate succession rules apply. Under Spanish common law, the order of priority is:

  1. Children and descendants (first priority)
  2. Parents and ascendants
  3. Surviving spouse
  4. Siblings and their descendants
  5. Other relatives
  6. The Spanish state

The surviving spouse inherits directly only if there are no children, parents, or other direct relatives. If there are children, the spouse receives usufruct over one third of the estate — not ownership.

For expat couples who have not made wills, this outcome — a surviving spouse with usufruct but not ownership, dependent on cooperation with stepchildren or children from a previous relationship — can be deeply problematic.


Autonomous Community Rules: Madrid vs Catalonia vs the Basque Country

Spain's inheritance law is not uniform across all regions. Several autonomous communities have their own succession laws (derechos forales) that differ significantly from the Spanish common law described above.

Region Key difference for surviving spouses
Catalonia Surviving spouse may inherit the entire estate in some circumstances; more favourable rules
Aragon Different legítima structure; fourth of the estate (cuarta vidual) for surviving spouse
Navarra Surviving spouse has stronger usufruct rights
Basque Country Different forced heirship rules
Madrid, Andalusia, Valencia (and most others) Spanish common law applies

If you live in Catalonia, your surviving spouse's rights are significantly stronger than if you live in Madrid — even if you are not a Spanish national. The applicable regional law is determined by your vecindad civil (civil domicile within Spain), which for most expats defaults to the common law (derecho común) unless you have been resident in a foral region long enough to acquire its civil domicile.


How EU Regulation 650/2012 Changes the Picture for Expats

For expats in Spain, the applicable succession law — and therefore the surviving spouse's rights — depends on the rules of EU Regulation 650/2012 (Brussels IV).

Default rule: The law of the country of habitual residence at death applies. For a long-term expat resident in Spain, this means Spanish law — including the legítima and the spouse's usufruct right.

Choice of law: An EU citizen can choose the law of their nationality instead. This is significant:

The choice of law must be made explicitly in the will. Without it, Spanish law applies — including the legítima that limits what the surviving spouse can receive.


Unmarried Partners: A Warning for Expat Couples

Spanish law treats married couples and unmarried partners very differently in the context of succession.

Under Spanish common law, an unmarried partner — regardless of how long the relationship has lasted — has no automatic inheritance rights. If you die without a will, your unmarried partner inherits nothing under Spanish intestate law. Everything goes to children, parents, or other relatives first.

Some autonomous communities (Catalonia, Aragon, Navarra, the Basque Country) recognise parejas de hecho (registered civil partnerships) and give registered partners inheritance rights similar to spouses. But in most of Spain — including Madrid and Andalusia — an unregistered partner has no legal claim.

For expat couples living together in Spain who are not married, this is a critical gap. A will is not optional — it is essential.


Practical Steps for Expat Couples in Spain

1. Make a Spanish will — even if you have a will in your home country. A Spanish notarial will, registered with the Registro Central de Últimas Voluntades, is the most effective way to protect your surviving spouse. It allows you to maximise what the spouse receives within the legal limits.

2. Consider a choice of law clause — if you are an EU citizen and your home country's succession law is more favourable to the surviving spouse, a choice of law clause in your will can apply that law instead of Spanish law.

3. Check which region's law applies — if you live in Catalonia, Aragon, Navarra, or the Basque Country, local succession law may apply. A Spanish lawyer can advise which rules govern your estate.

4. Document your assets clearly — the surviving spouse's practical ability to exercise their rights depends on knowing what assets exist, where they are held, and how to access them. This is where Sucesio's asset documentation and transmission service is most valuable.

5. If unmarried, act now — a will is not optional. An unmarried partner in most of Spain has no inheritance rights without one.


What Sucesio Does for Surviving Spouses

Sucesio is not a legal document service — it does not replace a will or a notary. But it addresses the practical reality that follows a death, which legal documents alone cannot solve.

For a surviving spouse in Spain:

The will establishes the legal framework. Sucesio ensures the practical reality matches the intention.


Frequently Asked Questions

Does a surviving spouse automatically own the family home in Spain? Not under Spanish common law. If there are children, the surviving spouse typically receives usufruct — the right to live in and use the home — while the children receive legal ownership. Full ownership of the home can be left to the surviving spouse only up to the tercio de libre disposición (one third of the estate). A well-drafted will can maximise this, but it cannot override the children's legítima.

Can children force a surviving spouse to sell the family home in Spain? In theory, children who own the legal title (subject to the spouse's usufruct) cannot force a sale while the usufruct exists. However, when the surviving spouse dies, the usufruct ends and the children gain full control. The practical relationship between surviving spouses and children — particularly from previous relationships — can become complicated. A will that clearly addresses this is essential.

Does the surviving spouse pay inheritance tax in Spain? Yes, but the rates and allowances depend on the autonomous community. In most regions, direct family members (including spouses) benefit from significant reductions. In Madrid and Andalusia, spouses may qualify for a 99% tax relief (bonificación), meaning the tax bill is close to zero. The rules change regularly — always verify with a local tax adviser.

My spouse and I are both British. Does Spanish law still apply? If you were both habitually resident in Spain at the time of death and made no choice of law, Spanish succession law applies — including the legítima and the usufruct for the surviving spouse. To apply English law instead (which has no forced heirship for adults), you need an explicit choice of law clause in your will, made before death.
