The Human Rights Campaign Foundation tracks developments in the legal recognition of same-sex marriage around the world. Working with our network of alumni and partners, we lift up the voices of local advocates and share tools, resources, and lessons learned to empower movements for marriage equality.

Current State of Marriage Equality
There are currently 29 countries where same-sex marriage is legal: Argentina, Australia, Austria, Belgium, Brazil, Canada, Colombia, Costa Rica, Denmark, Ecuador, Finland, France, Germany, Iceland, Ireland, Luxembourg, Malta, Mexico, the Netherlands, New Zealand, Norway, Portugal, South Africa, Spain, Sweden, Switzerland, Taiwan, the United Kingdom, the United States of America and Uruguay.
Austria: The Constitutional Court of Austria ruled on December 4, 2017 that denial of marriage equality was discriminatory, legalizing same-sex marriage. Marriage equality took effect January 1, 2019.
Taiwan: The Taiwan Constitutional Court ruled in 2017 that marriage could not be restricted to opposite-sex couples and gave parliament two years to enact legislation legalizing same-sex marriage. Parliament passed legislation to legalize same-sex marriage which went into effect May 24, 2019, making Taiwan the first country to enact marriage equality in Asia.
Ecuador: Legalized after Ecuador’s Constitutional Court found on June 12, 2019 that its ban was unconstitutional, marriage equality took effect in Ecuador on July 8, 2019.
Costa Rica: The Supreme Court of Costa Rica ruled in November 2018 in support of the historic January 2018 advisory opinion of the InterAmerican Court of Human Rights that marriage equality was consistent with Costa Rica's obligations under the American Convention on Human Rights. The Supreme Court set May 26, 2020 as the deadline for the National Assembly to enact such legislation, but it did not meet that deadline, and marriage equality came into effect on that date.
Switzerland: On December 16, 2020, the Swiss Parliament overwhelmingly passed legislation extending marriage to same-sex couples.
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.
This list includes a few of the many countries where HRC Global is tracking developments in support of marriage equality in 2021.
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 of these 29 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.
