Same-sex marriage in Arizona

The U.S. state of Arizona has recognized same-sex marriage since a court ruling on October 17, 2014, required the state to do so. The state had denied marriage rights to same-sex couples by statute since 1996 and by an amendment to its state constitution approved by voters in 2008. Two lawsuits in federal court that challenged the state's policies ended with a decision that the ban was unconstitutional and the state did not appeal that ruling.

Before the court ruling, several Arizona cities and towns provided civil unions or domestic partnerships.

Civil union legislation
In late December 2008, a gay rights activist from the United Kingdom has announced for his plans to push for a civil partnership measure on the Arizona ballot, with the unions providing exactly the same rights found under civil marriage. Based on polls, a measure would be significantly likely to pass. Additionally, Equality Arizona, which opposes the "separate-but-equal" status of civil union, have stated that they are checking out their options in 2010 in response to Arizona Proposition 102 (2008).

Several other proposals to put an initiative legalizing civil unions in the state have been made, from the public as well as from within the government. A website sponsoring such an initiative, which is currently in the process of collecting signatures, has also been launched.
