Cross-border workers around Geneva or Basel, expatriates in Zurich or Lausanne, Franco-Swiss couples: Switzerland is a neighbor but not an EU member. EU regulations do not apply. Switzerland uses its Federal Act on Private International Law, Hague conventions on children and the Lugano Convention for maintenance. Swiss occupational pensions follow their own rules.
An initial overview, not a consultation
This page outlines Swiss law and its connections with French law. It is an initial overview, not a consultation: every situation depends on specific facts and local law changes. For each case, I work with a colleague based in Switzerland, who confirms these initial details for your circumstances and acts before local courts when necessary.
0 — Your situation
You live in France and work in Switzerland, or vice versa. You live in Geneva and one spouse wants to return to France. You have Swiss second-pillar pension assets. Proceedings began across the border. Family law and civil procedure are federal, but court organization belongs to the cantons.
1 — Which court?
In Switzerland. Jurisdiction lies at the respondent’s domicile, or the applicant’s domicile if resident for a year or Swiss. A Swiss spouse abroad may also apply at their place of origin if proceedings at either spouse’s domicile are impossible or cannot reasonably be required. For cross-border workers, workplace is irrelevant: domicile and residence matter.
Parallel proceedings. Swiss courts stay a case if an identical action is pending abroad and the foreign decision can be recognized within a reasonable time; they decline once such a decision is presented. French courts may also defer to Swiss courts seised first. Filing dates matter on both sides.
Second pillar: exclusive Swiss jurisdiction. Only Swiss courts can divide occupational pension assets held with a Swiss institution. A French divorce cannot do so; additional proceedings are needed in Switzerland before the competent court or, otherwise, at the pension institution’s seat.
2 — Which law?
Before the Swiss court. Swiss law always governs divorce and generally ancillary effects, except notably spousal maintenance and matrimonial property, which have their own rules.
Matrimonial property from Switzerland’s perspective. Spouses may choose in writing the law of their current or future common domicile, marriage location or either spouse’s nationality. Otherwise common-domicile law applies. The ordinary Swiss regime is participation in acquisitions. On changing common domicile between countries, the new law applies retrospectively to the marriage date unless spouses exclude retrospective effect in writing, retain the former law by agreement or have a marriage agreement.
For spouses moving to Switzerland after marrying in France, Swiss courts may apply Swiss law retrospectively to the whole marriage while French courts often retain French law for at least part of it. A written choice of matrimonial property law valid in both countries prevents costly differences for mobile couples and cross-border workers.
3 — Recognition
In Switzerland. French divorce judgments are recognized if issued in the State of either spouse’s domicile, habitual residence or nationality. Additional conditions apply if only the applicant, or neither spouse, is French. Recognition can be refused for breach of defense rights or Swiss public policy.
Divorce without a judge. The Federal Supreme Court has long accepted recognition of foreign private divorces. The Swiss Embassy in France lists documents for registering a divorce agreement deposited with a notary. It does not divide Swiss second-pillar assets: additional Swiss proceedings remain necessary.
Maintenance. The 2007 Lugano Convention binds Switzerland and the EU: maintenance decisions are recognized without special proceedings and enforced after a declaration of enforceability, on presentation of a standard certificate.
4 — Your relationship
Divorce under Swiss law. Divorce may follow a joint petition with complete or partial agreement; a unilateral request after two years’ separation; or serious reasons making continuation unbearable before that period. Maintenance after divorce is payable if a spouse cannot reasonably provide appropriate support, including suitable retirement provision.
5 — Your children
France and Switzerland are parties to the 1980 Child Abduction and 1996 Child Protection Conventions, to which Swiss private international law refers. Jurisdiction follows the child’s habitual residence and decisions are recognized across the border. Immediate return may be requested after wrongful removal. Switzerland’s central authority is the Federal Office of Justice; the cantonal superior court hears the return application at a single level.
Since 1 July 2014, parental responsibility is generally joint, including after divorce. A parent moving the child’s residence abroad needs the other parent’s consent or a decision by the court or child and adult protection authority.
6 — Your assets
Occupational pensions follow mandatory division rules. Assets accrued during marriage up to divorce filing are generally divided equally. Specific rules apply to pensions already paid, and equitable compensation is due if division is impossible. These assets come in addition to matrimonial property liquidation and French compensatory payments: calculate them early.
Second and third pillars and property on both sides of the border often require coordination between French and Swiss courts and both countries’ notaries.
The Lugano Convention also determines maintenance jurisdiction: besides the respondent’s domicile, the creditor may apply at their domicile or habitual residence, or to the divorce court unless its jurisdiction rests solely on a spouse’s nationality. The 1973 Hague Maintenance and 1956 New York Recovery Conventions supplement this framework.
Points to watch
French divorce judgments or registered divorces never settle Swiss second-pillar assets: plan additional Swiss proceedings.
Moving between France and Switzerland may retrospectively change matrimonial property law in Swiss courts’ eyes.
Filing dates matter: Swiss courts stay for an earlier French action and vice versa.
A cross-border worker’s workplace does not establish jurisdiction; habitual residence matters.
