Half-siblings (half-sisters or half-brothers) are people who share one parent. They may share the same mother but different fathers (in which case they are known as "uterine" siblings or "maternal half-siblings"), or they may have the same father but different mothers (in which case, they are known as "agnate" siblings or "paternal half-siblings". In law, the term "consanguine" is used in place of agnate). In law (and especially inheritance law), half-siblings have often been accorded treatment unequal to that of full siblings. Old English common law at one time incorporated inequalities into the laws of intestate succession, with half-siblings taking only half as much property of their intestate siblings' estates as siblings of full-blood. Unequal treatment of this type has been wholly abolished in England, but still exists in the U.S. state of Florida.
