Washington does not officially recognize new common-law marriages. Unlike some other states, you cannot acquire marital rights in Washington simply by living together for a certain period or holding yourselves out as married.
Although common-law marriage is not recognized, Washington courts may grant certain protections to couples in “committed intimate relationships” (sometimes called “meretricious relationships”). A committed intimate relationship is a stable, marriage-like partnership in which two people live together, share finances or property, and function similarly to a married couple—without being formally married.
When such a relationship ends, Washington courts may:
If you established a valid common-law marriage in a state that does recognize it, Washington may honor that marriage if it meets all the legal requirements of the originating state. This can impact issues like property rights, inheritance, and spousal maintenance should you move to Washington.
Understanding the distinction between a committed intimate relationship and a legal marriage can have significant implications for asset division, estate planning, and other financial matters. If you believe you’re in a relationship that may qualify for protections under Washington law, consider consulting with a qualified family law attorney to clarify your rights and obligations.
