Final rulings issued
The Constitutional Chamber of the Supreme Court of Justice struck down the nation's ban on marriage equality on Aug. 8, 2018, but delayed its ruling from taking effect until May 26, 2020 (18 months after it was published in the Judicial Bulletin). The ruling was a direct result of the Inter-American Court of Human Rights' January 2018 marriage-equality ruling, which obligates Costa Rica and 15 other nations without marriage equality to let same-sex couples marry. Those nations, signatories of the American Convention on Human Rights, are Barbados, Bolivia, Chile, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru and Suriname. Four other signatory nations already have marriage equality: Argentina, Brazil, Colombia and Uruguay. Mexico has full marriage equality only in 17 of its 31 states and in Mexico City, the federal capital.
Costa Rica's presidential election, held April 1, 2018, morphed into a referendum on marriage equality after an evangelical Christian, Fabricio Alvarado, catapulted into first place in the first round (besting 12 other candidates) by making resistance to the Inter-American Court ruling the centerpiece of his campaign. Polls showed the runoff between the top two vote-getters to be too close to call, but on election day, marriage-equality supporter Carlos Alvarado won in a landslide — 61% to 39%.
Sixteen Americas nations
"THE COURT DECIDES ... by six votes to one that: ... Under Articles 1(1), 2, 11(2), 17 and 24 of the [American] Convention [on Human Rights], States must ensure full access to all the mechanisms that exist in their domestic laws, including the right to marriage, to ensure the protection of the rights of families formed by same-sex couples, without discrimination in relation to those that are formed by heterosexual couples, as established in paragraphs 200 to 228."
In a binding ruling released Jan. 9, 2018, the Inter-American Court of Human Rights instructed 20 nations that are signatories to the American Convention on Human Rights to bring in marriage equality: Argentina, Barbados, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname and Uruguay. Marriage equality is already in place in Argentina, Brazil, Colombia and Uruguay, and Mexico has marriage equality in 17 of its 31 states and in Mexico City, the federal capital.
"All countries are obligated to apply the Convention as the court applies it, so it is binding on all as precedent," said Hunter T. Carter, a partner at Arent Fox who has tried a case in the Inter-American Court and represents Chilean same-sex couples in the Inter-American system.
Overseas municipalities Bonaire, Saba and Sint Eustatius have marriage equality. Constituent countries Aruba, Curaçao and Sint Maarten do not, though they partially recognize Dutch marriages from elsewhere.
Mexican states (there are 31) are a hotspot of the marriage-equality movement. To date, 17 states and the federal capital Mexico City have achieved marriage equality via three different pathways. My article is here.
All overseas departments and collectivities — see the France entry above — have marriage equality. The links above show a same-sex couple marrying in nine of the 11 jurisdictions.
See above for the lengthy list of British places with marriage equality. Northern Ireland, Sark (part of Guernsey) and the overseas territories Anguilla, British Virgin Islands, Cayman Islands, Montserrat, and Turks and Caicos Islands do not have marriage equality.
A law repealing marriage equality and replacing it with domestic partnerships that offer the benefits of marriage took effect June 1, 2018, making the Bermuda government the first in the world to end marriage equality. On June 6, 2018, the portion of the law that re-banned marriage equality was struck down by the same court that had legalized marriage equality in May 2017. On July 5, 2018, the government appealed the new strikedown to the Court of Appeal. On Nov. 23, 2018, the government lost again and marriage equality returned to Bermuda. Unwilling to give up, on Dec. 13, 2018, the government announced an appeal to the United Kingdom Privy Council, the British overseas territory's court of final appeal, where the government will likely lose again. Same-sex couples may continue to marry during the ongoing appeal.
There has been only one other repeal of marriage equality in history: California voters ended marriage equality via a ballot initiative (Proposition 8) in 2008. A court ruling overturning the voters' decision took effect in 2013 when the U.S. Supreme Court declined to hear an appeal by the initiative's sponsors. Voters in the U.S. state of Maine blocked a marriage-equality law from coming into force in 2009, then reversed themselves and allowed marriage equality in 2012. Voters in Slovenia blocked a marriage-equality law from coming into force in 2015. A court ruling in the British overseas territory Cayman Islands allowed marriage equality for 13 days in 2019 before a higher court issued a stay. No same-sex couple married during that time.
The Cayman Islands Grand Court legalized marriage equality on March 29, 2019, striking down the British overseas territory's ban. On April 10, 2019, the day the first marriage was to take place, the Court of Appeal issued a stay of the Grand Court ruling, blocking marriage equality until the government's appeal of the ruling runs its course.
On May 22, 2015, Ireland became the first nation to legalize same-sex marriage by popular vote. Irish people amended their constitution to bring in marriage equality by a landslide margin of 62.07% to 37.93%.
Four of the five U.S. territories — Guam, Northern Mariana Islands, Puerto Rico, U.S. Virgin Islands — were covered by the U.S. Supreme Court's nationwide marriage-equality ruling on June 26, 2015. American Samoa was not.
The United States Minor Outlying Islands — Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll and Wake Island in the Pacific Ocean, and Navassa Island in the Caribbean Sea — would have marriage equality. Their population nowadays is a small number of temporarily assigned scientists and military personnel.
Marriage equality exists in much of Antarctica, given the nations that claim portions of the continent as national territory: Argentina, Australia, Chile, France, New Zealand, Norway, United Kingdom.
On the high seas

U.S. Indian tribes
There are 567 of them, and they are not covered by the June 26, 2015, U.S. Supreme Court ruling that legalized same-sex marriage nationwide. At least 22 tribes, listed below, have legalized same-sex marriage to date. A number of others follow the marriage law of the state in which they are located, so same-sex marriage is legal within the tribe without any additional tribal action.
• Coquille Indian Tribe in Oregon (2009)
• Mashantucket (Western) Pequot Tribal Nation in Connecticut (2010)
• Suquamish Tribe in Washington (2011)
