Quick Guide To When Marriage Equality Expansions Takes Effect | The American Foundation for Equal Rights (AFER) has posted a guide for when the new expansions of marriage equality will take effect. Washington’s law will take effect December 6 (30 days after the election). Maine’s law could take effect as early as December 6 as well, but it depends on when the governor officially proclaimed the result of the vote. Maryland’s law was set to take effect January 1, though that is a government holiday and licenses don’t take effect for 48 hours, so January 4 is the earliest day a same-sex couple will be legally married there. In addition, if the Supreme Court decides not to hear the Proposition 8 case when it conferences on November 20, the Ninth Circuit ruling takes effect and same-sex marriage becomes legal there.
