On February 26, 2025, Thailand’s National Anti-Corruption Commission (NACC) issued a notification titled “Criteria for Individuals Living Together as Husband and Wife that Are Considered as De Facto Spouses (No. 2) B.E. 2568 (2025).” This new notification, published in the Government Gazette on March 7, 2025, took effect retroactively from January 22, 2025. Prior to this notification, the term “spouses” specifically included “individuals living together as husband and wife” without registering marriage, referring to similar language at the time in Thailand’s Civil and Commercial Code. However, it was unclear whether this term included same-sex and other nontraditional couples. After the Marriage Equality Act revised this language in the Civil and Commercial Code to only refer to “spouses” (with a gender-neutral Thai word), the NACC took the opportunity to issue a new notification that simply replaces any mention of “husband and wife” with “spouses,” thereby removing the ambiguity. As a result, this new notification covers same-sex de facto spouses of politicians and high-ranking officials. These spouses’ assets must now be declared together with the officials’ assets. Additionally, same-sex de facto spouses of state officials are prohibited from engaging in business with the Thai government that may present conflicts of interest. Importantly, the notification also impacts the interpretation of the Office of the Prime Minister’s (OPM) Regulation on the Giving or Receiving of Gifts by Public Officials B.E. 2565 (2022). In this regard, same-sex de facto spouses of government officials are now also prohibited from accepting gifts or other benefits related to official duties. This is because the OPM regulation references the NACC definitions when defining “family members” to include “de facto husband and wife.” Under the OPM regulation, public officials and their supervisors are strictly prohibited from permitting or condoning family members’ acceptance of gifts or other benefits related to

The Thai cabinet has approved a draft amendment of the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes as proposed by the Ministry of Digital Economy and Society to strengthen measures against technological crimes, particularly targeting call center scams and cyber fraud. Following the Council of State’s review, the emergency decree will be become effective immediately upon its enactment and publication in the Government Gazette. While the draft amendment is not yet publicly available, the government recently indicated that the emergency decree aims to empower authorities with decisive measures to combat cybercrime effectively. It underscores the shared responsibility among various sectors, including banking, telecommunications, and online platforms, in safeguarding against technological crimes. Key provisions of the draft amendment of the emergency decree include: Telecommunications provider obligations: Telecommunications service providers must suspend SIM cards associated with criminal activities. The National Broadcasting and Telecommunications Commission and mobile service providers themselves are authorized to temporarily suspend mobile phone numbers if there is reasonable suspicion of involvement in criminal activities. Banking responsibilities: Financial institutions are required to promptly report mule accounts to the Anti-Money Laundering Office to facilitate quick restitution to victims. The Anti-Money Laundering Transaction Committee is empowered to order the return of funds to victims without requiring a final court ruling. Penalties for noncompliance: The amended emergency decree introduces penalties for noncompliance by regulated entities that fail to prevent criminal activities for offenses related to technology crimes in the following cases: Digital asset services: Those engaged in the buying, selling, or exchanging of digital assets, such as cryptocurrencies and digital tokens, as well as digital asset businesses that launder money obtained from online crimes by converting it into digital currency, will be subject to imprisonment for up to one year, a fine of up to THB 100,000,

On October 16, 2024, Thailand’s Anti-Corruption Cooperation Committee (ACCC) issued a notification to enhance anticorruption standards in public procurement. The new notification (officially “Notification of the Anti-Corruption Cooperation Committee on the Procurement Budget and Minimum Standards of the Policy and Directions for Anticorruption in Relation to Procurement according to Section 19 of the Public Procurement and Supplies Administration Act B.E. 2560”) supersedes previous guidelines and imposes stricter compliance requirements on business entities involved in the government procurement processes. The updates not only align with the goals of Thailand’s Public Procurement and Supplies Administration Act B.E. 2560 (2017) but also reflect the government’s resolution to mitigate corruption, particularly in high-value public contracts. The ACCC’s new notification introduces additional definitions, lowers budget thresholds for compliance, and strengthens business obligations. Key Components The new notification continues the previous guidelines’ requirement that businesses seeking to bid on government procurement projects meet the specified minimum standards—such as communicating and implementing anticorruption policies at all organizational levels, establishing a code of conduct, and providing related training programs to employees. The notification also introduces a number of changes, the most notable of which are detailed below. “Entrepreneur” definition. The definition of this term is narrowed to entities involved in the public procurement bidding process. Previously, the definition broadly applied to all business entities engaged in selling goods or services. Threshold for mandatory compliance. The project budget threshold that necessitates compliance with the minimum standards is  THB 300 million—a reduction from the previous threshold of THB 500 million. Minimum standards to prevent unfair competition. The new notification introduces a specific definition for “disturbing fair competition,” establishing clear parameters around actions that disrupt competitive fairness within public procurement. Continued compliance requirements. Businesses’ compliance with the minimum standards must now extend from the date of bid submission to the
