Recognition of same-sex unions in the Americas

Many countries in the Americas grant legal recognition to same-sex unions, with almost 85 percent of people in both North America and South America living in jurisdictions providing marriage rights to same-sex couples.

In North America, same-sex marriages are recognized and performed without restrictions in Canada, Costa Rica, Cuba, Mexico, and the United States.

Same-sex marriages are also performed in the Dutch territories of Aruba, Curacao, Bonaire, Sint Eustatius and Saba, the Danish autonomous territory of Greenland, and in all French overseas departments and collectivities (Guadeloupe, Martinique, Saint Barthélemy, Saint Martin and Saint Pierre and Miquelon). Furthermore, Sint Maarten recognizes same-sex marriages performed in the Netherlands. The British Territories of Bermuda and the Cayman Islands also perform civil partnerships.

In South America, same-sex marriages are recognized and performed without restrictions in Argentina, Brazil, Chile, Colombia, Ecuador and Uruguay as well as the jurisdictions of French Guiana, the Falkland Islands and South Georgia and the South Sandwich Islands. Free unions that are equivalent to marriage have begun to be recognized in Bolivia.

On 8 January 2018, the Inter-American Court of Human Rights (IACHR) ruled that the American Convention on Human Rights mandates and requires the legalization of same-sex marriage. The landmark ruling was fully binding on Costa Rica and set a "binding precedent" in the other signatory countries. The Court recommended that governments issue temporary decrees legalizing same-sex marriage until new legislation is brought in. The ruling applies to Barbados, Bolivia, Costa Rica, the Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru and Suriname. The Supreme Courts of Honduras, Panama, Peru and Suriname have rejected the IACHR ruling, while the Supreme Courts of Costa Rica and Ecuador adhered to it.

2018 Inter-American Court of Human Rights ruling
On 9 January 2018, the Inter-American Court of Human Rights issued an advisory opinion that states party to the American Convention on Human Rights must grant same-sex couples accession to all existing domestic legal systems of family registration, including marriage, along with all rights that derive from marriage. The opinion was issued after the Government of Costa Rica sought clarification of its obligations to LGBT people under the convention. The opinion sets precedent for all 23 member states, 19 of which did not recognize same-sex marriage at the time of the ruling: Barbados, Bolivia, Chile, Costa Rica, Dominica, the Dominican Republic, Ecuador, El Salvador, Guatemala, Grenada, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, and Suriname. Of these, all but Dominica, Grenada and Jamaica recognize the jurisdiction of the Court. However, states must each individually apply the ruling before it takes effect.

The territories are also bound by the European Convention on Human Rights to pass laws legalizing some form of same-sex union, although to date only Bermuda and Cayman Islands have done so.
