Common Law Marriage States

Created by FindLaw's team of legal writers and editors.

Under the common law marriage doctrine, you're considered legally married -- despite not having a marriage license, a ceremony, or a marriage certificate -- if you meet specific requirements (according to state law). The benefits of common law marriage include the right to inherit upon the death of one spouse and the right to spousal support and an equitable division of property should the marriage terminate.

The jurisdictions that recognize common law marriage and the requirements of each are listed below. In addition, states will recognize a couple as married if their union is contracted by a common law marriage state and meets those requirements, even if these states themselves lack statutes providing for common law marriages.
