Similar to other types of corporate disputes, tax-related conflicts often begin with an earnest attempt to resolve matters outside the courtroom. The prospect of engaging in tax litigation can be daunting, given the potential strain on commercial relationships, the legal expenses, and the uncertainty surrounding its resolution. However, there are instances when tax litigation becomes the sole avenue for seeking redress. For individuals and entities contemplating the pursuit of tax-related legal remedies, the Thai legal system offers an accessible, impartial, and equitable platform for dispute resolution. Tilleke & Gibbins’ latest update to Tax Litigation in Thailand provides an outline for navigating tax-related disputes within the Thai legal framework. It aims to equip readers with a fundamental understanding of procedures and practices within the Thai tax litigation landscape. The full guide is available through the button below.

One morning, a California-based company mapping its Southeast Asia rollout opened an unexpected cease-and-desist letter from a Vietnamese IP firm. To the company’s surprise, the letter asserted that a local client already owned the company’s brand in Vietnam and threatened legal action. This is not an isolated incident. In another recent matter in the sports industry, a squatter demanded at least USD 48,000 from our client to “resolve” a similar conflict. For brands entering Vietnam or expanding distribution there, these tactics can create acute risk at precisely the point at which market momentum is building. Vietnam’s rapid economic growth and deepening integration into global trade have made it an increasingly attractive destination for multinational brands. Those same dynamics have intensified a longstanding issue: trademark squatting. Vietnam has modernized its IP framework over the past decade, but its strict first-to-file trademark system continues to incentivize opportunistic filings by parties with no legitimate interest in a mark. As more foreign brands build their reputation abroad before turning to Vietnam, squatters remain alert to timing gaps and enforcement frictions. The First-to-File System: Advantages and Vulnerabilities Vietnam adheres closely to the first-to-file principle under its Law on Intellectual Property. In practice, exclusive trademark rights belong to whoever submits the earliest valid application to the Vietnam Intellectual Property Office, regardless of prior use in Vietnam. This approach offers administrative clarity and reduces evidentiary burdens compared to use-based jurisdictions. Yet it also creates fertile conditions for squatting. Bad-faith actors regularly monitor foreign markets, identify brands gaining traction, and move quickly to register those marks domestically, often long before the genuine owner enters the market or prioritizes local filings. By the time the true brand seeks protection, the squatter’s application (or registration) stands as a legal obstacle, pushing businesses toward costly oppositions, cancellations, or uncomfortable negotiations

Thailand has expanded the circumstances under which state agencies may bypass competitive bidding procedures to address urgent security challenges. On November 28, 2025, Thailand’s Ministry of Finance published the Ministerial Regulation Determining Cases of Procurement by Specific Method (No. 6) B.E. 2568 in the Royal Gazette, introducing a new pathway for procuring supplies and services needed to address cyber and military threats that may affect the stability of government agencies or the nation. For technology vendors, cybersecurity firms, and defense contractors, this regulatory change creates immediate opportunities to engage directly with government buyers facing urgent security challenges. New Fast-Track Category for Security Threats The regulation amends Thailand’s Public Procurement and Supplies Management Act B.E. 2560 (2017) to add a new category of procurement that qualifies for the “specific method”—a noncompetitive, direct selection process. Previously, agencies could use this expedited method only in limited circumstances, such as emergencies, cases with proprietary technology requirements, or national security operations. The new provision explicitly covers procurement of supplies related to preventing or resolving cyber or military threats that could impact the stability of a state agency or the country. This addition recognizes the urgent nature of modern security challenges, where competitive bidding timelines may leave agencies vulnerable during critical threat windows. State agencies dealing with active cyberattacks, preparing defensive measures against anticipated threats, or responding to military security concerns can now move directly to negotiate with qualified vendors rather than conducting lengthy public tender processes. Vendor Considerations Vendors offering cybersecurity solutions now have a regulatory avenue to work directly with government clients when stability concerns are present. These solutions include threat detection systems, anti-ransomware tools, incident response services, firewalls, and security consulting. Similarly, defense contractors providing military equipment or specialized security supplies can pursue direct engagement channels where traditional procurement methods would create

Thailand’s Department of Business Development (DBD), through its Office of Central Company and Partnership Registration, has released multiple draft orders for public consultation until December 12, 2025. These draft orders aim to strengthen the business registration process, with a focus on the requirements for establishing and amending the principal office address of a partnership or limited company, verification of authorized signatories, and measures to identify and prevent registrations involving persons linked to suspicious or high-risk activities. The draft orders’ proposed requirements are outlined below. Principal Office Verification The principal office address of a partnership or limited company, including house registration code, house number, full address details, and building name, must be fully aligned with the civil registry. The registrar will strictly verify this before accepting any registration or amendment. If the address used for registration is already registered for at least five other companies, the company must submit a consent letter from the person authorized to allow use of the principal office, along with supporting documents proving the right to use the address. Signatory Certification Compliance Duties Persons certifying directors’ signatures on registration forms are responsible for verifying their identities, maintaining up-to-date information, and complying with the requirements of the DBD’s Biz Regist digital registration system. Certain supporting documents proving the qualifications of certifying persons are also required, with some exceptions for specific professional roles. Identity and qualification verification must be renewed upon the completion of one year from the date of registration as a certifying person, or if the certification credentials expire before the one-year period ends, in accordance with the verification requirements. Verification of Suspicious Parties Any partner, shareholder, or director linked to a predicate offense will be required to meet with the registrar in person for further verification steps. For all parties related to a company
