Common-law marriage is not just living together, and it is rarely legally recognized today.

In short: Many assume that living together for years creates a common-law marriage, but this is a persistent myth. In reality, only a handful of U.S. jurisdictions recognize these unions. Without a formal license or ceremony, couples must meet strict criteria to prove they are legally wed in the eyes of the law.

Common-law marriage, also known as marriage in fact, is a legally binding union formed without the typical state-issued license or formal ceremony. Contrary to popular belief, simply cohabitating, sharing a home, or raising children is insufficient to establish this status. Instead, the law requires three specific elements: an intimate relationship, a mutual agreement to be married, and a public declaration that the couple is husband and wife. Because there is no public record of the union, these marriages are often viewed with suspicion by courts, placing the burden of proof squarely on the party claiming the marriage exists.

The origins of this practice in the United States are often misunderstood. While some suggest it stems from English common law, it appears to have developed as a practical necessity in colonial America. In regions where access to government officials or religious leaders was scarce, settlers required a functional alternative to ceremonial marriage. This need persisted as populations expanded into the sparsely populated American West. Today, however, the institution has largely been phased out, with only seven states and the District of Columbia still permitting the formation of new domestic common-law marriages as of 2022.

When a relationship ends, there is no such thing as a common-law divorce. Because these unions are considered lawful marriages, they must be dissolved through formal judicial proceedings, just like any other marriage. Disputes frequently arise during separation or upon the death of a partner, particularly regarding inheritance or employment benefits. If a couple fails to present themselves as married to the public—such as by using joint names or financial accounts—courts are likely to reject claims of a valid union. Ultimately, the 'acid test' is a public declaration; secret common-law marriages are not recognized by the law.
