Common-law marriage is a legal framework that recognizes a couple as married without a formal ceremony or marriage license. This type of marriage typically requires that the couple live together for a significant period, present themselves as a married couple, and intend to be married. The rules for common-law marriage vary by state or country, and not all jurisdictions recognize it. In places where it is acknowledged, couples may need to provide evidence of their relationship, such as shared finances or joint property, to establish their marital status legally.
