The Civil Solidarity Pact (PACS) is a contract between two adult persons, of different sexes or of the same sex, to organise their cohabitation. It was promulgated by the Law of 15 November 1999. It sets the rights and obligations of the parties in terms of material support, housing, estate, taxes and social rights. However, it has no effect on the rules of parentage and parental authority if one of the parties is already a parent.
The PACS may be dissolved at the request of one of the two parties by sending a declaration to the court of instance. It is automatically broken by the marriage or death of one of the two parties.
