The family affairs judge with territorial jurisdiction is:
– the judge of the place where the family residence is located;
– if the parents live separately, the judge of the place of residence of the parent with whom the minor children habitually reside in the event of joint exercise of parental authority, or of the place of residence of the parent who exercises this authority alone;
– in other cases, the judge of the place where the parent who did not initiate the proceedings resides.
In the event of a joint application, the competent judge is, depending on the choice of the parties, that of the place where one or the other resides.
However, where the dispute concerns only maintenance, a contribution to the upkeep and education of the child, a contribution to the costs of the marriage or compensatory allowance, the court with jurisdiction may be that of the place where the creditor spouse or the parent who is the main carer of the children, even if they have reached the age of majority, resides.
Territorial jurisdiction is determined by residence on the day of the application.
