Same-sex marriage has been legal in Guam since June 9, 2015, following a ruling from the District Court of Guam on June 5 that the territory's prohibition of same-sex marriage was unconstitutional. The court case, Aguero v. Calvo, had been filed in April 2015 following the Ninth Circuit Court of Appeals' decisions in Latta v. Otter and Sevcik v. Sandoval that Idaho's and Nevada's denial of marriage rights to same-sex couples was unconstitutional. Guam was the first territory of the United States to recognize same-sex marriage.
On August 12, 2015, the Guam Legislature passed the Guam Marriage Equality Act of 2015 by a vote of 13–2. The law came into effect on August 27, officially incorporating the federal court ruling into statutory law. Previously, Guam had denied marriage rights to same-sex couples by statute since 1994.
