Thailand’s Senate has passed a marriage equality bill, allowing the country to become the first in Southeast Asia to recognize same-sex marriages.

On Tuesday, the upper house approved the measure in its final reading, with 130 votes from the 152 members in attendance. Four senators voted against, and 18 abstained.

The legislation will now be submitted to King Maha Vajiralongkorn for assent, which is widely expected to be granted. It will go into effect 120 days after it is published in the Royal Gazette.

Thailand will become the third Asian jurisdiction to legalize gay marriage, following Nepal and Taiwan.

LGBTQ advocates and human rights organizations applauded the bill’s passage.

The legislation defines marriage as a partnership between two people and replaces references to “men,” “women,” “husbands,” and “wives” with gender-neutral terms. It would also give LGBTQ couples inheritance and adoption rights equal to those in heterosexual marriages.

While Thailand is known for its vibrant LGBTQ culture and tolerance, activists have struggled for decades to overcome conservative attitudes.

Many people have criticized laws for failing to recognize transgender and nonbinary people, who will still be unable to change their gender on official IDs.
