Sororate marriage

Husband marrying the sister of his wife

Sororate marriage is a type of marriage in which a husband marries or engages in sexual relations with his wife's sister, usually after the death of his wife or if his wife has proven infertile. The fraternal equivalent is levirate marriage. From an anthropological standpoint, this type of marriage strengthens the ties between both groups (the wife's family or clan and the husband's) and preserves the contract between the two to provide children and continue the alliance.
