Same-sex marriage has been legally recognized in the District of Columbia since December 18, 2009, when Mayor Adrian Fenty signed a bill passed by the Council of the District of Columbia on December 15, 2009. Following the signing, the measure entered a mandatory Congressional review of 30 work days. Marriage licenses became available on March 3, 2010, and marriages began on March 9, 2010. The District became the first jurisdiction in the United States below the Mason–Dixon Line to allow same-sex couples to marry.
