The Chile's Congress approved the equal marriage bill on Tuesday, with both houses of the national parliament authorizing the legislation with overwhelming majorities. The motion, which also allows same-sex couples to adopt children, had been stuck in Congress for five years.
"It will now be possible for all couples, whatever their sexual orientation, to live in love and create families," the president said in a televised statement.
Chile has become the eighth Latin American country to allow same sex marriage, as well as the 31st worldwide.
