You are separating from a partner of a different nationality. Or your child lives in a different country from you. In these situations, one question immediately arises: which court has jurisdiction over custody? And which law applies?
Globalisation and professional mobility have made these family situations far more common. They raise real legal challenges: international jurisdiction, recognition of foreign judgments, and the risk of parental abduction.
French private international law on child custody provides answers — through international conventions, EU regulations and domestic conflict-of-law rules. But you need to know them, and plan ahead.
This article sets out the key rules applicable in France when parents of different nationalities separate. For a personalised analysis, book a consultation with Maître Menuet via the Contact page.
1. Child Custody in France and Private International Law: Core Principles
The child’s habitual residence: the main connecting factor
In international family matters, the basic rule is clear: the court with jurisdiction to rule on custody is that of the country where the child has their habitual residence at the time of the dispute.
Habitual residence is not an administrative concept. It is assessed on factual criteria: the length and regularity of the stay, the child’s school and social integration, and the presence of close family. These are the elements a judge will examine.
This criterion is common to most international instruments: the 1980 Hague Convention, the 1996 Hague Convention on the Protection of Children, and the Brussels II ter Regulation within the European Union.
The best interests of the child: a universal standard
Regardless of the applicable legal framework, the best interests of the child take precedence. This principle, enshrined in Article 3 of the United Nations Convention on the Rights of the Child (UNCRC), guides all decisions relating to custody — at both national and international level.
It notably implies preserving the child’s emotional bonds with both parents, except in exceptional circumstances.
2. Applicable Legal Framework: Conventions and EU Regulation
The Hague Convention of 25 October 1980 on International Child Abduction
This convention, ratified by over 100 states, has a specific purpose: to secure the prompt return of a child wrongfully removed or retained outside their country of habitual residence.
It applies when three conditions are met:
-
-
- The child is under 16 years of age;
- The child has been removed or retained in breach of custody rights recognised under the law of the state of their habitual residence;
- The parent holding those custody rights requests the child’s return.
-
The procedure runs through the Central Authorities designated by each signatory state. In France, this is the International Civil Judicial Assistance Bureau (DEDIPE) at the Ministry of Justice.
The Brussels IIter Regulation (EU No. 2019/1111)
Within the European Union (except Denmark), the Brussels IIter Regulation — applicable since 1 August 2022 — is the key text governing parental responsibility and the recognition of custody decisions.
This regulation introduces two major advances:
-
-
- Automatic recognition of decisions handed down in another Member State, without an exequatur procedure;
- A reinforced enforcement regime for certain decisions, particularly those ordering the return of a child or granting a certified right of access.
-
It also strengthens the child’s right to be heard in cross-border proceedings.
Other applicable instruments
Outside the EU, other instruments may apply depending on the states involved: the 1996 Hague Convention on the Protection of Children (jurisdiction, applicable law, recognition), or bilateral treaties concluded by France with specific countries.
Absent any convention, French domestic private international law rules — including the conflict-of-law provisions of the Civil Code — will govern the matter.
3. International Parental Abduction: Prevention and Remedies
International parental abduction occurs when one parent removes or retains a child in another country without the other parent’s consent, in breach of their custody rights. This constitutes a criminal offence under French law (Article 227-5 of the Penal Code: wrongful removal of a child) and a serious violation of the child’s best interests.
Return mechanisms
Where the 1980 Hague Convention applies, the affected parent must contact the Central Authority of their country without delay. Timing is critical: after one year from the removal, return becomes harder to obtain if the child has settled into their new environment.
In France, Hague Convention return applications are heard by the Family Court Judge (juge aux affaires familiales, or JAF) of a specially designated court.
Exceptions to immediate return
Return may be refused in strictly limited cases:
-
-
- The child faces a grave risk of physical or psychological harm upon return;
- The child has settled in their new environment after more than one year;
- The child, having reached a sufficient age and level of maturity, objects to being returned.
-
These exceptions are interpreted narrowly by French and European courts, which are vigilant against their use as a means of frustrating the return procedure.
4. Recognition and Enforcement of Foreign Custody Orders in France
Within the European Union, the Brussels IIter Regulation provides for automatic recognition. For certified decisions on rights of access or the return of a child, enforcement is direct, with no further steps required.
Outside the European Union, two routes exist:
-
-
- An international convention binding France and the state of the decision (e.g., the Luxembourg Convention of 20 May 1980);
- Failing that, the exequatur procedure under ordinary law before the judicial tribunal.
-
In the latter case, the French judge verifies that the foreign decision does not contravene French international public policy and that the right to a fair hearing was respected.
5. Practical Steps When Facing an International Separation
Here are the key steps to take as soon as a dispute arises:
- Gather evidence of the child’s habitual residence: school enrolment certificate, lease agreement, statements from family or friends, medical records in France.
- Consult a lawyer specialised in international family law before any travel abroad or any informal agreement.
- In the event of wrongful removal, act immediately: contact the French Central Authority (BECCI) and a lawyer — deadlines are critical.
- Secure any amicable agreement by having it approved by a court. An unratified agreement is difficult to enforce abroad.
- Identify the applicable convention for the countries involved: the rules differ depending on whether the other parent is based in an EU Member State, a Hague signatory, or a third country.
Conclusion
Child custody in France in cross-border situations is a technical field. Each case must be assessed against the applicable texts — the Hague Convention, Brussels IIter, domestic rules — and the countries involved.
Anticipating difficulties, gathering the right evidence and acting promptly are the key factors in protecting your parental rights and your child’s best interests.
