Who inherits without a will in Monaco?

Statute, customary and religious law apply side by side

Monaco has a civil-code system of its own, in which the children inherit first and the law protects close relatives.

A general outline, not a checked profile

We have not yet researched Monaco line by line. This page describes how countries with the same legal tradition usually work, so that the map is not blank, and it can differ from the law in Monaco. Reliable, current information is hard to find for many African countries: laws are often not published online or not translated, customary and religious rules are unwritten or differ from one community to the next, and reforms are not always reported.

Can you help? If you know the rule in Monaco, or you work with its law, please email us what it says and where it is written. We will check it and update the page, with credit if you wish.

The default, not your case. This page describes what applies when there is no valid will. Succession law is reformed often, a will changes everything, and the rules for an estate with a foreign element are complex. This is general information, not legal advice.

A spouse and children survive

In the civil-code tradition the children inherit first, in equal shares, and the surviving spouse takes a share set by the law or a right to use part of the estate.

A spouse survives, but no children

A spouse with no children usually shares the estate with the parents and the siblings, and takes the whole estate if there are none.

No spouse: who comes next

Children first, then the parents and the brothers and sisters, then more distant relatives, and finally the state.

A partner who is not married

A partner who is not married generally has no automatic right to inherit, though some small states recognise registered partnerships; a will is the way to provide for them.

What a will cannot take away

Close relatives, usually the children and sometimes the spouse and parents, have a reserved share that a will cannot take away.

If the person or the property is abroad

The law of the place where land lies usually governs the land, and the law of the person's last home usually governs the rest. An estate with a foreign element needs advice in the country.

What to watch for

  • Small states often have their own rules on who may own property and on taxes on inheritance, so a foreign heir should check both.

Understand the legal system first

Monaco belongs to the Civil law family. Succession law grows out of the legal tradition, so it helps to know how the system works.
