Adultery Lawsuit Under Thailand’s New Law: How Siam Center Law Group as a Leading Law Firm in Bangkok Can Assist

Adultery Lawsuit Under Thailand’s New Law - Same-sex couple seeking legal advice from a lead law firm in Bangkok

The enactment of the Same-Sex Marriage Act B.E. 2568 and the amendment to Section 1523 of Thailand’s Civil and Commercial Code redefine the legal landscape for adultery lawsuits under Thailand’s new law. This reform ensures that all legally married spouses—regardless of gender or sexual orientation—have the right to file a lawsuit for compensation. As a recognized leading law firm in Bangkok, Siam Center Law Group is prepared to guide you through the intricacies of these changes.

1. Overview of the New Adultery Laws in Thailand

Effective from January 22, 2025, the amendment to Article 1523 replaced gendered terms with the neutral term “spouse,” allowing equal rights across all genders facebook.com+5nationthailand.com+5siamcenterlawgroup.com+5. Now, any spouse who can prove extramarital conduct may file an adultery lawsuit under Thailand’s new law, whether the conduct was public or private, heterosexual or same-sex.

2. Why the Reform Matters

Gender Equality in Civil Claims

Before the amendment, wives could only sue female paramours, while husbands could sue either gender. The constitutional court ruled this unconstitutional under Article 27, prompting the reform thainews.prd.go.thbangkokpost.com+1nationthailand.com+1.

Coverage for Private Affairs

The reforms remove the requirement for public exposure of the affair. Private emotional or physical infidelity, even a one‑time encounter, can now support a lawsuit.
