Many foreigners living in Spain assume that, in the event of death, their spouse will automatically become the sole heir — especially if there are no children.In Spain, however, this is far from guaranteed. This widespread misconception repeatedly leads to legal uncertainty and family conflict.
Peter Capitain
A common misconception
In countries such as Germany, the United Kingdom or the United States, the surviving spouse is usually the main — or even sole — heir. Spanish inheritance law follows a very different logic:
marriage alone does not automatically entitle the surviving partner to the entire estate.
If no will exists, statutory succession rules apply — and in Spain these rules often produce outcomes that come as an unpleasant surprise.
What happens if there are no children?
The key question is whether other close relatives of the deceased are still alive.
No children, but surviving parents
This is one of the most common — and most conflict-prone — scenarios:
-
The parents of the deceased inherit ownership of the estate.
-
The surviving spouse is entitled only to usufruct over half of the estate.
-
Usufruct allows the use of assets — for example, continuing to live in the family home — but does not permit their sale.
In practice, this can mean that the surviving spouse lives in a property that legally belongs to their parents-in-law — a situation that often generates tension and disputes.
No children and no parents
Only in this case does the law provide that:
-
The surviving spouse inherits the entire estate.
What if there is a will?
A will can significantly improve the position of the surviving spouse, but it has clear legal limits:
-
Surviving parents are entitled to a compulsory share (legítima) and cannot be fully disinherited.
-
Nevertheless, a will allows for structured estate planning and helps to avoid many practical complications.
Regional differences
Spain does not have a uniform inheritance system. Regions such as Catalonia, the Basque Country, Navarre, Galicia and the Balearic Islands apply their own inheritance rules.
What applies in Madrid may be very different in Barcelona — often to the advantage of the surviving spouse.
International succession law: an often overlooked option
Foreign nationals residing in Spain may, in many cases:
-
choose the inheritance law of their country of nationality,
-
provided this choice is expressly stated in a will.
Without a will, the law of the deceased’s last habitual residence usually applies — often Spanish law — even if the deceased was not a Spanish national.
Conclusion: a will is not a formality
For foreigners living in Spain, failing to make a will can be a serious risk, particularly in childless marriages.
A will:
-
protects the surviving spouse,
-
prevents family disputes,
-
provides legal certainty,
-
and is relatively simple and inexpensive to arrange in Spain.
Anyone living in Spain or owning property there should not assume that inheritance law works the same way as in their home country.
What many only discover after a death can be avoided with proper planning.
