Same-sex marriage in Argentina

Legislative history

Deputies from the Socialist and New Encounter parties introduced bills to legalize same-sex marriage in 2009. After extensive debate, a unified bill passed the Chamber of Deputies in May 2010 by 126 votes to 110. The Senate approved it on July 15 with 33 votes in favor. President Cristina Fernández de Kirchner signed the law into effect on July 21, 2010. Polling at the time indicated strong public support for the measure.

Civil unions and cohabitation

Before full marriage equality, Argentina established protections for same-sex partners through other means. Unregistered cohabitation received nationwide recognition in 2008, granting pension rights after five years of living together. Civil unions were legalized in specific jurisdictions starting in 2002 and became available nationwide on August 1, 2015. These unions provide hospital visitation and inheritance benefits similar to marriage.

Legal challenges and court cases

Activists filed constitutional challenges against civil code articles limiting marriage to opposite-sex couples. In December 2009, a court in Tierra del Fuego registered the first same-sex marriage in Latin America, though it was later annulled. Other courts in Buenos Aires also issued rulings supporting marriage equality before the national law took effect. These judicial decisions paved the way for the final legislative victory.
