Abstract
French family law has just undergone tremendous changes. The may 17 Act which allows same sex marriage means the acknowledgement of a right for couples either homosexual or heterosexual. These couples can be married or not. Beyond the diversity, we can however feel the emergence of a right for the couple, that is to say common rules for all couples. The couple, from every angle, became an essential and inescapable element of family law which has its proper rules.
