Séparation de corps et d'habitation or only Séparation de corps ('Separation of Person') was one of two forms of divorce which was available in France prior to the French Revolution.
[1] Séparation de corps was a permission from the court for two spouses to legally live separate lives, juridically independent from each other, and dissolved their respective legal responsibilities toward each other.
They were, however, still formally married and were not allowed to remarry as long as their spouse was alive.
[2] In order to have a divorce, a woman had to prove that her husband was insane, or that he had abused her.
[3] Séparation de corps differed from the other option, Séparation de biens ('Separation of Property') in which the wife was declared to be of legal majority and allowed to handle her own economy, which was legally regarded as a form of divorce.
