The Swiss authorities online
If you want to get a divorce, you must submit an application to the court. You can file a joint application if you and your partner agree to divorce or either partner can file a unilateral application.
It is easiest if both spouses agree to divorce and file a joint application:
Contact the competent court in your or your partner’s place of residence. The courts are organised differently from canton to canton. Ask your canton’s judicial authority or a lawyer if you are not sure which court to contact.
Note: If both of you consent to a divorce, you can only file for divorce in the place where you live if you have lived in Switzerland for at least one year. Otherwise, the petition for divorce must be submitted in the place where your spouse lives.
You can only get a divorce in Switzerland if it is impossible or unreasonable to submit the petition for divorce in abroad in the place where one or both of the spouses live. In this case, the petition for divorce may be filed in the place of origin of one of the spouses.
The judge will inform the individuals’ communes of residence and origin of the divorce. The communes of origin then record the divorce in the civil register.
