Group marriage

Group marriage or conjoint marriage is a marital arrangement where three or more adults enter into sexual, affective, romantic, or otherwise intimate short- or long-term partnerships, and share in any combination of finances, residences, care or kin work. Group marriage is considered a form of polygamy. While academic usage has traditionally treated group marriage as a marital arrangement, more recent usage has expanded the concept to allow for the inclusion of non-conjugal unions. Colloquial usage of group marriage has also been associated with polyamory and polyamorous families.
