Civil marriage equality in effect at the state level since 2008. (Same-sex couples may legally marry.)
Marriage equality recognized by the Mashantucket Pequot Tribal Nation. Tribal law states that, "Two persons may be joined in marriage on the Mashantucket Pequot Reservation," without specifying gender.
In 2005, Connecticut became the second state in the U.S., following Vermont, to adopt civil unions, and the first to do so without judicial intervention.
Connecticut was the third state to legalize marriage equality following Massachusetts (2004) and California (2008).
All existing civil unions were automatically converted to marriages on 1 October 2010.
