BANGKOK — Hundreds of LGBTQ+ couples in Thailand are expected to make their wedded status legal Thursday, the first day a law took effect granting them the same rights as heterosexual couples. The enactment of the Marriage Equality Act makes Thailand the first country in Southeast Asia and the third place in Asia to legalize same-sex marriage, after Taiwan and Nepal.
