Bilateral descent is a system of family lineage in which the relatives on the mother's side and father's side are equally important for emotional ties or for transfer of property or wealth. It is a family arrangement where descent and inheritance are passed equally through both parents. Families who use this system trace descent through both parents simultaneously and recognize multiple ancestors, but unlike with cognatic descent it is not used to form descent groups. While bilateral descent is increasingly the norm in

had a bilateral society, where the descent of both parents were important. Genealogies featuring the legendary danish king Sigurd Snake-in-the-Eye gives him the matronymic name ''Áslaugsson'' due to his mother Aslaug's connection to Völsungs. Under bilateral descent, every tribe member belongs to two clans, one through the father (a patriclan) and another through the mother (a matriclan). For example, among the Himba, clans are led by the eldest male in the clan. Sons live with their father's clan and when daughters marry they go to live with the clan of their husband. However inheritance of wealth does not follow the patriclan but is determined by the matriclan i.e. a son does not inherit his father's cattle but his maternal uncle's instead.
