The Bank of Thailand (BOT) is seeking public comment on proposed amendments that would significantly expand know-your-customer (KYC) and customer due diligence (CDD) requirements for cash-related transactions at financial institutions (FIs) and specialized financial institutions (SFIs). Released on August 5, 2026, the proposed regulation would supersede BOT Notification No. 16/2569, which focused primarily on cash withdrawal transactions. The public comment period is open through September 3, 2026. The amendments reflect concerns that FIs and SFIs may be used to facilitate the movement, concealment, and conversion of criminal proceeds, potentially damaging institutional operations and public confidence in the financial system. Expanded Scope of Covered Transactions The most significant change is the broadening of the definition of “cash-related transactions.” Previously, the regulation covered only cash withdrawals and uncrossed check withdrawals. The amended regulation extends coverage to include: Cash deposits, check deposits, or receipt of funds from the public not in the form of deposit accounts; Thai baht (THB) banknote exchange (different denominations); Receipt of cash for issuing checks and drafts; and Purchase, sale, or exchange of foreign banknotes. Mandatory Identity Verification and Risk Management For all cash-related transactions, FIs and SFIs must require customers, or authorized or delegated persons, to present identification or verify their identity before every transaction, including one-time (walk-in) transactions. Specific identification requirements vary by transaction type, customer nationality, and channel (branch vs. electronic). FIs and SFIs must also establish comprehensive risk management processes and procedures for cash-related transactions. These requirements include identifying customers or authorized representatives in accordance with transaction-specific verification standards, analyzing customer behavior, implementing risk-management measures proportionate to the customer’s risk profile, and recording abnormal behavior in relevant systems. The BOT also encourages institutions to proactively guide customers toward transaction channels that offer greater traceability than cash. For corporate customers in high-risk business sectors—including foreign

Securing a favorable judgment is often only the midpoint of a dispute. For businesses and investors, the more important commercial question is whether that judgment can be converted into actual recovery. In Thailand, this typically requires the judgment creditor to enforce the judgment through the Legal Execution Department by seizing, attaching, auctioning, or otherwise executing against the judgment debtor’s assets. Thailand’s schedule of these enforcement fees was last revised by an amendment to the Civil Procedure Code that took effect in September 2025. The Civil Procedure Code Amendment Act (No. 33) B.E. 2568 (2025) updated the schedule of execution officer fees listed in table 5 of the Civil Procedure Code. While the amendment did not eliminate the costs associated with enforcement, it lowered several key execution officer fees and abolished certain fees that previously applied even where enforcement did not ultimately result in the sale or disposition of assets. The reform is intended to reduce the financial burden associated with judgment enforcement and remove unnecessary obstacles to settlement once enforcement proceedings have commenced. As a result, it has practical implications not only for judgment creditors seeking to maximize recovery, but also for debtors considering settlement after enforcement has begun and for businesses and investors assessing litigation and credit risk in Thailand. Key Changes The amendment introduced several changes to the execution officer fee structure. First, where seized or attached assets are sold by public auction or otherwise disposed of, the execution officer fee has been reduced from 3% to 2% of the sale or disposition proceeds. This fee remains separate from announcement costs and other out-of-pocket expenses incurred during the enforcement process. Second, where seized or attached funds are paid to a judgment creditor, the execution officer fee has been reduced from 2% to 1% of the amount recovered.

Thailand’s Office of the Insurance Commission (OIC) has issued guidelines clarifying the boundaries between permissible and prohibited activities for unlicensed individuals—including influencers, bloggers, and content creators—when communicating about insurance products on social media. The Good Practice Guidelines for Persons Not Licensed as Insurance Agents or Brokers Regarding the Dissemination of Insurance Content Through Digital Media B.E. 2569 (2026) took effect on July 24, 2026. Activities Requiring a License The guidelines reserve the following activities for licensed agents and brokers: Soliciting or facilitating insurance contracts. Providing personalized advice on product suitability. Recommending policy cancellation to purchase promoted products. Creating links that facilitate contract formation. Receiving performance-based compensation tied to policies or premiums generated. Importantly, boilerplate disclaimers such as “this is not a recommendation to buy insurance” will not shield individuals from liability if the OIC views the content as personalized advice or solicitation. Permitted Activities Unlicensed persons may present general educational content about insurance—such as explaining terminology, sharing industry statistics, reporting news, or sharing personal experiences—provided the content does not target specific individuals to purchase from specific companies. The guidelines also set out best practices for communication, including presenting information in a fair and balanced manner that covers both benefits and limitations, encouraging consumers to read policy terms and consult licensed professionals, verifying information from credible sources before dissemination, and exercising special care when the audience may include vulnerable groups such as persons aged 60 and older. Prohibited Practices Prohibited practices include fear-based marketing, creating artificial urgency, omitting material limitations, making exaggerated claims, falsely claiming professional credentials, using fake engagement mechanisms, and sharing false or misleading content. The guidelines also reinforce the prohibitions under section 83 of the Life Insurance Act B.E. 2535 and section 78 of the Non-Life Insurance Act B.E. 2535 against soliciting insurance contracts with foreign operators

Modern agricultural machinery is no longer purely mechanical but instead technology dependent. Modern tractors, harvesters, and other farm equipment increasingly incorporate embedded software, electronic control units, sensors, and digital diagnostic systems. While such technologies enhance efficiency, productivity, and precision farming, they also affect the manner of equipment repair and maintenance. As a result, farmers and independent repair providers may have little practical choice but to rely on authorized dealers, even for routine maintenance and repairs. Section 36 of Thailand’s Patent Act reflects the principle that the authorized sale of a patented invention usually exhausts the exclusive right of the patent owner over the specific product. This means that upon legal sale of the patented product, it can typically be used or resold without further authorization from the patent holder. This principle is relatively straightforward when applied to traditional mechanical equipment. Ownership of a machine ordinarily carries with it the practical ability to diagnose faults, replace worn parts, and restore the equipment to working order. Modern agricultural machinery, however, increasingly depends on embedded software, proprietary diagnostic systems, firmware updates, and other digital resources that may remain under the control of the manufacturer or patent holder. This tension lies within the “right to repair” debate. In the United States, on July 8, 2026, the Federal Trade Commission and five states announced a settlement with Deere & Company resolving allegations that Deere had unlawfully restricted farmers’ and independent repair providers’ ability to repair their equipment. Under the terms of the settlement, for the next ten years, Deere must provide repair resources, including software capabilities, on terms equivalent to those provided to authorized dealers. The Deere settlement highlights that the nature of ownership is changing, but legal concepts have not kept pace. Traditional patent-law concepts, including patent exhaustion, were developed with physical products
