Honestly, if you looked at a map of the world twenty years ago, the idea of a global list of countries that recognize same sex marriage would have been a very short, very lonely paragraph. Back in 2001, it was just the Netherlands. That was it. One country standing alone.
Fast forward to January 2026, and the landscape has shifted so dramatically it’s almost hard to keep track. We are now looking at nearly 40 countries—39 to be precise, with Thailand and Liechtenstein being the most recent additions—where you can walk into a government office and get a marriage license regardless of who you love. But it’s not just a "Western" thing anymore. The momentum has moved into places that, frankly, many experts thought would take decades to budge.
The Big Shift in Asia and Southeast Asia
For a long time, Taiwan was the lone wolf in Asia. They broke the seal in 2019 after a massive court battle. But 2025 was a total game-changer for the region. Thailand officially became the first Southeast Asian nation to legalize same-sex marriage, with the law taking full effect on January 23, 2025.
It wasn't just a quiet policy change. This was a massive cultural moment. We’re talking about a country where the tourism industry has always been "LGBTQ-friendly," but the legal system was lagging way behind. Now, same-sex couples in Thailand have the same rights to tax breaks, inheritance, and—crucially—medical consent as any other married couple.
What’s happening in Japan?
Japan is... complicated. It’s the only G7 nation that hasn't legalized it yet. If you’re following the news right now in early 2026, you’ve probably seen the "ping-pong" effect in their courts. Some district courts say the ban is unconstitutional; others say it’s fine. Most recently, the Tokyo High Court basically said it’s up to the Diet (their parliament) to fix it. People are waiting on a Supreme Court ruling that could land any day now, but for now, it’s a patchwork of "partnership certificates" that don’t actually carry the weight of a legal marriage.
The Orthodox Breakthrough: Greece
Greece surprised a lot of people in 2024. Why? Because it became the first majority Orthodox Christian country to pull the trigger on marriage equality. The Church was not happy about it. There were protests, some pretty heated rhetoric from bishops, and a lot of political tension.
But Prime Minister Kyriakos Mitsotakis pushed it through anyway. On February 16, 2024, the law went live. It didn’t just allow for weddings; it opened up full parental rights, including adoption. This was a massive signal to the rest of the Balkans and Eastern Europe. If Greece can do it, the "cultural barrier" excuse starts to look a lot thinner for countries like Montenegro or the Czech Republic.

Speaking of the Baltics
Estonia also stepped up. They started recognizing same-sex marriage on January 1, 2024. They were the first former Soviet-occupied country to do so. It’s a huge deal because it signals a total pivot away from the Russian sphere of influence, where "anti-propaganda" laws are the norm.
A Look at the Map: Who’s Actually on the List?
If you need the hard data for a move or just for your own knowledge, here is how the global list currently sits. It’s not just "The West."
Europe
The heavy hitters are all here: Netherlands (2001), Belgium (2003), Spain (2005), Norway (2009), Sweden (2009), Portugal (2010), Iceland (2010), Denmark (2012), France (2013), UK (2014/2020), Luxembourg (2015), Ireland (2015), Finland (2017), Germany (2017), Malta (2017), Austria (2019), Switzerland (2022), Slovenia (2022), Andorra (2023), Estonia (2024), Greece (2024), and Liechtenstein (2025).
The Americas
Canada was an early adopter in 2005. The U.S. followed in 2015 via the Obergefell ruling. Latin America has actually been a massive leader here: Argentina (2010), Brazil (2013), Uruguay (2013), Colombia (2016), Ecuador (2019), Costa Rica (2020), Chile (2022), Mexico (nationwide by late 2022), and Cuba (2022).

Africa and Oceania
South Africa remains the only country on the African continent to recognize same-sex marriage (since 2006). In Oceania, you’ve got New Zealand (2013) and Australia (2017).
The "Almost" Countries: Civil Unions vs. Marriage
There is this weird middle ground that a lot of people confuse with marriage. It’s the "Civil Union" or "Registered Partnership" trap.
Take India, for example. In late 2023, the Supreme Court basically said, "We hear you, but we can't make this a law—Parliament has to do it." So right now, queer couples in India can live together and have some protection against harassment, but they don't have a marriage certificate.
In Czechia, they recently "enhanced" their civil unions to include almost all the rights of marriage (like joint property), but they still refuse to call it "marriage." It’s a linguistic battle that feels petty but has real legal consequences for things like international recognition.
Why the "How" Matters
You’d think a law is a law, but how a country gets to countries that recognize same sex marriage status determines how stable that right is.
- Legislative Vote: This is the "gold standard." Think Australia or Thailand. The people’s representatives voted on it. It’s hard to undo.
- Court Rulings: This is how the U.S., Brazil, and Austria got there. A court said, "The constitution says everyone is equal, so you have to allow this." The downside? Courts can change their minds (as we've seen with other rights in the U.S. recently).
- Popular Referendum: This is rare. Ireland and Switzerland did it this way. It’s the ultimate "the people have spoken" move.
Realities for 2026 and Beyond
We aren't seeing a total global sweep. In fact, some places are backsliding.
Burkina Faso and Gabon have recently moved to explicitly ban same-sex unions or even criminalize the "promotion" of them. Even in the U.S., there are constant whispers about whether the Supreme Court might revisit the 2015 decision, though the Respect for Marriage Act passed in late 2022 provides a federal safety net.
If you are planning to get married abroad, you have to be careful. A marriage performed in Thailand is now legally recognized in most of the world, but if you take that marriage certificate to a country like Italy (which only does civil unions) or Namibia, your status might "downgrade" or vanish the moment you land.
Actionable Steps for Couples
- Check the "Reciprocity": Before moving or traveling long-term, see if your host country recognizes foreign same-sex marriages. Equaldex is a great real-time tool for this.
- Document Everything: Even in legal countries, carry digital copies of your marriage certificate and medical power of attorney. Bureaucracy can be slow to catch up to the law.
- Watch the Deadlines: Some countries, like Thailand, have a "waiting period" after the law passes before the first licenses are issued. In Thailand's case, that was 120 days after the royal assent.
The list of countries that recognize same sex marriage is growing, but it’s moving from a sprint to a marathon. The next big frontiers are likely in the Caribbean (watch Aruba and Curaçao) and potentially the first signs of movement in parts of East Asia like South Korea.
