Cross-border divorce in France: law, children, assets and lawyer

A cross-border divorce involving France is governed by separate rules on jurisdiction, applicable law, asset division, child arrangements and recognition of foreign decrees. Those rules must be analysed before you file, because the first court seised may determine where the proceedings continue and which legal issues can be decided there. For broader context on French procedural rules, international family law in France explains how French courts approach these questions. You will also find procedural guidance in the cross-border divorce France expat guide, and rules concerning children in cross-border parental rights in France. The official position of the EU institutions appears in the EU cross-border divorce rules.

Cross-border divorce law in France

A cross-border divorce raises three distinct questions: which court has jurisdiction, which substantive law governs the divorce, and whether the resulting decree will be recognised where it must take effect. Each question is answered by a different legal instrument. Confusing them can lead to a petition being filed in the wrong country, under the wrong law, or without a workable plan for enforcement.

The conflict of laws analysis should therefore precede any filing. It affects the financial regime, the treatment of property, child arrangements and the procedural route available to each spouse.

When French courts have jurisdiction

For an international divorce in France involving spouses domiciled in the EU, Regulation (EU) 2019/1111, known as Brussels II ter, governs jurisdiction. Under Article 3, a French court may hear the case when at least one jurisdictional ground exists on the date the petition is filed. The relevant date is not the date of separation or marriage.

• Both spouses are habitually resident in France: this is the clearest ground, and no further analysis of nationality is required.

• France was the last common habitual residence and one spouse remains there: French jurisdiction may continue after the other spouse has left.

• The respondent is habitually resident in France: the other spouse may file in France even if the applicant is living abroad.

• The spouses share French nationality: common nationality provides an additional jurisdictional ground under Article 3(1)(b), independently of their current residence.

Nationality and habitual residence are not interchangeable. For an Anglo-French family, habitual residence is established through facts such as schooling, employment, healthcare registration and stable social ties. A French passport held by a spouse living abroad does not, by itself, give a French court jurisdiction; the question is where that person's centre of life was genuinely situated on the relevant date.

Habitual residence and filing first

Brussels II ter contains a strict priority rule. Where proceedings could properly be brought in more than one EU Member State, the court first seised takes priority and the later court must decline jurisdiction. Priority arises when a valid petition is filed, not when it is served or when the first hearing takes place.

That makes the decision to file in France, or to file abroad before a French petition is lodged, a strategic decision rather than an administrative one. Member States differ in their timetables, disclosure requirements and judicial approach to contested proceedings. A French contested divorce before the tribunal judiciaire commonly takes between six and twenty-four months.

In this situation, I would prioritise advice from an international divorce lawyer in France before either spouse takes procedural steps. The relevant point is not simply speed: it is knowing whether a filing in France protects the forum you need, or allows the other spouse to secure priority elsewhere.

Applicable law under the Rome III Regulation

The Rome III Regulation determines the substantive law applicable to the divorce. It operates separately from jurisdiction, so a French court may hear the case while applying foreign divorce law, including English law, if the regulation so provides.

The spouses may make a written choice-of-law agreement before filing. It must be dated and signed, and may select the law of a current or qualifying former habitual residence, the nationality of either spouse, or the law of the court hearing the case. That choice can affect the grounds for divorce, the financial relief available and the judicial assessment of the marriage.

Without a valid agreement, the Rome III cascade applies. It begins with the law of the spouses'common habitual residence when the court is seised. For couples who have moved between countries, the result may be unexpected; the applicable law should be established before the petition is drafted.

Choosing a court abroad

Filing for a cross-border divorce in France is not always the preferable course. The decision should be tested against the law governing the divorce, the matrimonial regime applicable to property, spousal support and the likely enforcement of the decree in the country where assets are held.

English courts, for example, exercise broad judicial discretion when redistributing assets. They may therefore produce a more favourable result for the financially weaker spouse than the French prestation compensatoire, which is assessed against statutory criteria and is typically ordered as a lump sum.

A foreign divorce decree must also be capable of taking effect in France. An EU judgment may be recognised automatically under Brussels II ter, whereas a non-EU judgment generally requires an exequatur procedure before a French court. That question must be considered before you file abroad, particularly where French property, custody or enforcement in France is involved.

Instrument	Function	Applies in France since	Key rule
Brussels II ter (EU 2019/1111)	Jurisdiction over divorce, legal separation and annulment	1 August 2022	The first court validly seised has priority; the second must step back
Rome III Regulation (EU 1259/2010)	Applicable substantive law for the divorce	21 June 2012	Choice of law by written agreement; otherwise a cascade beginning with habitual residence
Divorce by mutual consent (Art. 229-1 Civil Code)	French non-judicial procedure without a court hearing	1 January 2017	Each spouse needs their own lawyer; notarial filing; 15-day reflection period
Exequatur (domestic French procedure)	Recognition and enforcement of a non-EU foreign divorce	Ongoing domestic rule	Mandatory for custody to become effective; legal representation obligatory

The French divorce by mutual consent procedure deserves particular caution. A notarial deed made without a judge may not be treated as equivalent to a judicial decision outside the EU. If the country concerned does not recognise non-judicial divorce, the spouses may remain legally married there, with continuing inheritance rights and matrimonial obligations.

That risk is material where either spouse has substantial ties to a non-EU country through property, nationality or family. It can affect remarriage, succession and the legal status of a child born into a later relationship. Cabinet Georges Parastatis examines recognition and enforcement at the outset of a cross-border matter, rather than waiting until a decree obtained abroad must be used in France.
