1. Archaic. A woman who cohabits with a man to whom she is not married. • A concubine is often considered a wife without title. A concubine’s status arises from the permanent cohabitation of a man and a woman as husband and wife although without the benefit of marriage. Cf. common-law wife under WIFE; COURTESAN. [Cases: Marriage 54. C.J.S. Marriage §§ 43–44.]
2. Hist. Eccles. law. A secondary or inferior wife, usu. in a polygamous marriage, who lacks the full rights and privileges of the first wife. • Although a concubine was expected to serve all the functions of a legitimate wife, she had no authority in the family or household, and was denied certain legal protections. For instance, her husband could easily disown her, she had no dower rights, and her children could not inherit from their father if he had children by his first wife. A concubine was also barred from certain spiritual comforts, such as churching after the birth of a child.
