Same-sex marriage is not legal in France. As of 2006, one same-sex marriage ceremony has been conducted in France and was declared void. France has a statute authorizing civil unions, known as PACS, between same-sex and unmarried opposite-sex couples. Same-sex marriage was an issue in the 2007 presidential election, with the Conservative UMP opposing it and the Socialist Party supporting it, though both candidates support civil unions (PACS).
