Binational Children Joint Custody in Geneva — Parental Authority, Relocation, Private International Law

Your child holds dual nationality, or one parent is about to leave Geneva for France, England, Lebanon. Custody and parental authority then raise two linked questions : which judge decides, and under which law ? This guide sets out the rules applicable in 2026 to binational children where at least one parent has a connection to Geneva.

1. Joint parental authority — the default rule

Since 1 July 2014, joint parental authority is the rule in Switzerland, including after divorce or separation (art. 296 para. 2 CC). Both parents make important decisions about the child together : school choice, non- emergency medical treatment, religion, relocation, administrative permits (passport, etc.).

Sole parental authority can only be awarded to one parent when this serves the child’s interest, notably in cases of :

• documented domestic violence,
• lasting geographic separation rendering cooperation impossible,
• chronic conflict that paralyses any joint decision,
• lasting incapacity of one parent (illness, addiction, detention).

Parental authority (who decides) must not be confused with physical custody (where the child lives) or with support (who pays). The three are legally distinct.

1.1 Shared residence or primary residence ?

Shared residence (close to 50/50) is favoured when practical conditions allow : proximity of homes, compatible schooling, parental coordination capacity, child’s maturity. For a couple with one parent in Geneva and the other in Annemasse, shared residence remains feasible if the school is near the border.

If the distance is too great (Geneva — Lyon, Geneva — Paris), shared residence is rarely viable. The judge then awards primary residence to one parent, with extended visitation for the other (alternating weekends, school holidays, extra holiday weeks).

2. Which law does the judge apply ? — art. 85 PILA

Art. 85 PILA refers to the Hague Convention of 19 October 1996 on jurisdiction, applicable law, recognition, enforcement and cooperation in respect of parental responsibility and measures for the protection of children. The rule is clear :

• Jurisdiction : authorities of the State of the child’s habitual residence.
• Applicable law : law of the State of the child’s habitual residence.

A child living in Geneva : Geneva court, Swiss law, regardless of the child’s nationality. A child living in France : French court, French law — even if the other parent is Swiss.

2.1 The concept of “habitual residence”

Habitual residence is not an administrative concept. It is where the child has the effective centre of life (school, friends, doctor, extracurricular activities). A temporary absence for holidays or a school stay does not shift habitual residence. A consensual move of several months does.

3. Moving abroad with the children — art. 301a CC

Art. 301a CC is the central provision for all binational parents. It provides that :

• the custodial parent may not change the child’s place of residence without the other parent’s consent or, failing that, judicial authorization,
• consent is required for any move abroad and for any move within Switzerland with significant consequences on the exercise of parental authority and personal relations.

Geneva — Annemasse counts as a move abroad subject to art. 301a CC, despite the short physical distance.

3.1 Criteria considered by the judge

The judge does not assess whether the move is “good” in the abstract, but whether it serves the child’s interest. The factors weighed include :

• the seriousness of the moving parent’s motivation (employment, family, remarriage, health reasons),
• the stability of the new setting (housing, school, family support),
• the remaining parent’s ability to maintain an ongoing relationship,
• practical visitation arrangements (distance, frequency, travel responsibility),
• the child’s age and views where their maturity allows (usually from 12, sometimes earlier).

3.2 Procedure in case of disagreement

If the other parent refuses, the parent wishing to move must apply to the Tribunal de protection de l’adulte et de l’enfant (TPAE) in Geneva (or to the divorce judge if proceedings are ongoing). The court hears both parents, obtains a report from the Service de protection des mineurs (SPMi) and, depending on age, hears the child.

Typical timeline : 3 to 9 months. An interim decision may be issued faster in emergencies.

4. International child abduction — 1980 Hague Convention

The Hague Convention of 25 October 1980 organizes the rapid return of a child wrongfully removed or retained in a State other than that of their habitual residence. It is the central safeguard against unilateral moves.

4.1 When is there an “abduction” ?

Wrongful removal or retention occurs when : the removal breaches a right of custody conferred by the law of the State of habitual residence, and that right was actually exercised at the time of removal. Swiss joint parental authority counts as “custody right” for the Convention. Leaving with the child without consent amounts to wrongful removal even if the moving parent had physical custody.

4.2 Return procedure

The left-behind parent applies to the Central Authority of the State where the child has been taken (Switzerland : Federal Office of Justice, FOJ). That authority transmits to the destination State, which seizes its competent judge. Decision on return is generally rendered within weeks. The judge does not decide custody on the merits : they order return or refuse, leaving the State of habitual residence to rule afterwards.

4.3 Exceptions to return

Return may be refused if : more than one year has passed and the child has settled in the new environment ; there is a grave risk that return would expose the child to physical or psychological harm (art. 13 let. b) ; the child objects with sufficient maturity. These exceptions are strictly construed.

5. International mediation

The 1996 and 1980 Hague instruments encourage mediation. Several Geneva mediators specialize in cross-border family conflicts. Mediation can produce a binational parenting agreement ratifiable by the Swiss judge and enforceable in France via recognition procedures.

Next steps

If you are considering a cross-border move — or fear an imminent unauthorized removal — an initial consultation at CHF 50 (30 minutes) allows for legal analysis and strategy. In case of actual or imminent abduction, contact the firm immediately : superprovisional measures may be obtained within the day.
