Domestic partnership in Washington (state)

State-registered domestic partnerships (SRDP) in Washington were created in 2007 following the Andersen v. King County decision. Subsequent legislation made an SRDP the equivalent of marriage under state law. As a result of the legalization of same-sex marriage in the state, starting on June 30, 2014, SRDPs became available only when at least one of the partners was sixty-two years of age or older.
