Many couples get married abroad and later settle in France, often without giving much thought to the legal consequences of their marriage. Yet one essential question deserves careful attention: which matrimonial property regime applies to your marriage?
The answer is not always obvious—and it can have significant consequences for your assets and your family.
Your matrimonial regime does not depend only on where you live
A common misconception is that living in France automatically means being subject to the French legal regime of community of property reduced to acquisitions.
In reality, this is not always the case.
The applicable matrimonial regime depends on several factors, including:
- the country where the marriage was celebrated,
- the spouses’ first habitual residence after the marriage,
- their nationality,
- and whether or not a marriage contract was signed.
As a result, a couple married abroad may be subject to a foreign matrimonial regime, sometimes very different from French law—often without being aware of it.
The Hague Convention: an often-unknown automatic change of regime
For many couples married before 29 January 2019, the Hague Convention of 14 March 1978 may apply.
This convention includes a little-known but crucial rule: the matrimonial regime may change automatically over time.
This mechanism is known as automatic mutability.
In practical terms, when spouses settle permanently in a new country, their matrimonial regime may become, after a certain period, the regime of their new country of residence—without any deliberate action or formal choice on their part.
For example, a couple married abroad and initially subject to a separation of property regime may, several years after moving to France, find themselves subject to the French legal community regime… without ever having chosen it.

Why can this automatic change be problematic?
Such an automatic change may have major consequences:
- changes in the ownership of assets,
- difficulties when buying or selling real estate in France,
- complications in the event of separation or divorce,
- unexpected effects upon death.
These situations are often discovered too late, at a time when the financial and family stakes are already high.
The notary: a key professional to clarify and secure your situation
A notary is the legal professional best placed to help couples with international backgrounds understand their matrimonial property regime.
In particular, the notary can:
- determine which matrimonial regime actually applies to your marriage,
- check whether an automatic change has occurred or may occur in the future,
- clearly explain the practical consequences for your assets,
- and, where appropriate, assist you in choosing or changing your matrimonial regime to better suit your personal, family, and financial situation.
