Partial legalisation

In some nations, same-sex marriage can be performed only in certain states.

Mexico: In June 2015, the Mexican Suprme Court ruled that it was unconstitutional for states to ban same sex marriage.

In 2009, Mexico City was the first place to legalise same-sex marriage. The state of Coahuila followed in 2014.

In May 2012, Quintana Roo declared all marriages between same-sex couples as legal. But the move did not happen without complications when same-sex marriages were suspended in January 2012 by the secretary of state.

By 2015, courts in 22 states of Mexico had ruled at least once that same-sex partners can marry one another. Cases have been filed in at least four other states.

Laws underway

AUSTRALIA:  The first same-sex couples married in the Australia's Capital Territory in 2013. A court ruling then overturned same-sex marriages. When same-sex couples have lived together for more than two years they achieve "De Facto" status, which provides some protections and responsibilities afforded through marriage.

SLOVENIA: Parliament approved by a vote 51 to 28 to extend a bill on the freedom to marry to same-sex couples. The bill awaits the president's signature.

COLOMBIA: In December 2012, a committee in the Colombian Senate voted 10-5 to extend the freedom to marry. Colombia's lawmakers have not passed a law to regulate gay marriage. The struggle for homosexual couples to get married continues.
