International Institutions & Marriage Equality

The Inter-American Court of Human Rights is an independent judicial institution of the Organization of American States. In 2018, it issued an advisory opinion to Costa Rica that signatories of the American Convention on Human Rights are obliged to make same-sex marriage legal. The Court’s guidance applies to 20 signatory countries and has proven a powerful tool in advocating for marriage equality in these countries.

The European Court of Justice (ECJ) serves as a high court in the European Union. In 2018, the ECJ determined that all EU countries were required to recognize the same-sex marriages of EU and non-EU citizens for purposes of immigration, regardless of whether same-sex marriage is legal in those countries. In recognition of this decision, the Supreme Administrative Court of Bulgaria affirmed in 2019 that the country would recognize such same-sex marriages for the purposes of immigration.

Methodology

This page is based on a review of legislation and judicial decisions recognizing same-sex marriage. It does not identify countries that recognize other kinds of relationships between same-sex couples, such as civil unions, registered partnerships or domestic partnerships.

We note that processes for obtaining a marriage license for same-sex couples in some countries differ across localities, such as in Mexico where, in light of a constitutional court ruling, some states have enacted marriage equality while, in other states, same-sex couples must seek an amparo from a federal court to obtain a license.

Same-sex married couples in many countries do not share all of the same rights and benefits as different-sex married couples, such as the right to adoption. In some countries, same-sex couples also experience additional restrictions. For example, in Taiwan same-sex marriage is only available to Taiwanese citizens or a citizen of a foreign country that recognizes same-sex marriage who seeks to marry a Taiwanese citizen.
