BANGKOK (AP) — Thailand’s landmark marriage equality bill was officially written into law Tuesday, allowing same-sex couples to legally wed.

The law was published in the Royal Gazette after endorsement by King Maha Vajiralongkorn, and will come into effect in 120 days. This means LGBTQ+ couples will be able to register their marriage in January next year, making Thailand the third place in Asia, after Taiwan and Nepal, to allow same-sex marriage.

The bill, which grants full legal, financial and medical rights for marriage partners of any gender, sailed through both the House of Representatives and the Senate in April and June respectively.

“Congratulations to everyone’s love,” Prime Minister Paetongtarn Shinawatra wrote on X, adding the hashtag #Love Wins.

Thailand has a reputation for acceptance and inclusivity but struggled for decades to pass a marriage equality law. Thai society largely holds conservative values, and members of the LGBTQ+ community say they face discrimination in everyday life.

The government and state agencies are also historically conservative, and advocates for gender equality had a hard time pushing lawmakers and civil servants to accept change.

Bangkok Deputy Governor Sanon Wangsrangboon said last week that the city officials will be ready to register same-sex marriages as soon as the law gets enacted.

The legislation amended the country’s Civil and Commercial Code to replace gender-specific words such as “men and women” with gender-neutral words such as “individual.”

The government led by the Pheu Thai party has made marriage equality one of its main goals. It made a major effort to identify itself with the annual Bangkok Pride parade in June, in which thousands of people celebrated in one of Bangkok’s busiest commercial districts.

The organizers of Bangkok Pride announced on Facebook that it will organize a wedding for couples who wish to register their marriage on the very first day that the law becomes effective.
