Common Law Marriage

Common Law Marriage by State


Common Law Marriage

Gavel and Gold wedding bandsTo be defined as a common-law marriage within the states that allow it, the two people must: agree that they are married, live together, and present themselves as husband and wife. Common-law marriage is generally a non-ceremonial relationship that requires "a positive mutual agreement, permanent and exclusive of all others, to enter into a marriage relationship, cohabitation sufficient to warrant a fulfillment of necessary relationship of man and wife, and an assumption of marital duties and obligations." Black's Law Dictionary 277 (6th ed. 1990).

Before modern domestic relations statutes, couples became married by a variety of means that developed from custom. These became the elements of a "common-law marriage," or a marriage that arose through the couple's conduct, instead of through a ceremony. In many ways, the theory of common-law marriage is one of estoppel—meaning that couples who have told the world they are married should not be allowed to claim they aren't when in a dispute between themselves.
