Impact of COVID-19 on Commercial Contracts in Thailand: Force Majeure

Informed Counsel

COVID-19 has had an economic impact across a wide range of industries, including hospitality, airlines, automotive, construction, logistics, and more, and many performance obligations on contractual parties have been rendered impossible. However, many others—while certainly more difficult, complicated, or expensive—remain literally or legally possible.

While COVID-19 will continue to have a devastating impact on health and economies globally, governments—including Thailand’s—have implemented preventive and responsive measures in an attempt to mitigate that impact. On May 24, 2020, for example, the Committee for Government Procurement and Supplies Management circulated guidelines for the administration of contracts between private parties during the COVID-19 pandemic, announcing that the COVID-19 pandemic qualifies as a force majeure event. The specific period of force majeure in Thailand began with the government’s announcement of a state of emergency on March 26, 2020. See the previous article for more details on this measure.

As market circumstances continue to evolve along with the impact of COVID-19, companies in Thailand are paying special attention to the role force majeure plays in navigating the various legal implications of commercial contracts during the outbreak.

Force Majeure Clauses under Thai Law   

In the midst of the COVID-19 pandemic many are wondering whether parties will be excused from performance under the doctrine of force majeure, by which parties can be excused from contractual performance that becomes impossible due to an extraordinary or exogenous event.

For contracts that have no force majeure clause, the definition of force majeure under section 8 of the Civil and Commercial Code will automatically be applied. However, parties may negotiate a force majeure clause and establish a course of action to follow in such events of force majeure. This clause can also pertain to things like excuse of liability, right to terminate or revise the contract, and distribution of damages due to force majeure.

Every force majeure clause should be considered and interpreted separately and in light of the contract as a  whole, as the precise terms of that clause will control the outcome. It may be easier to argue COVID-19 has triggered a force majeure clause if the clause expressly includes a pandemic, epidemics, or quarantines as examples of events giving rise to the clause. For example, the WHO categorizing  COVID-19 as a pandemic should lend support to parties seeking to enforce force majeure clauses in contracts that contain the term. In the absence of these examples, a party claiming the benefit of a force majeure clause would first have to demonstrate that COVID-19 is a circumstance that falls within the language of the provision.

Application of Force Majeure

When a company invokes a force majeure clause to excuse its contractual nonperformance, it must show that the contractual obligation in question cannot be performed due to unforeseeable, extraordinary circumstances beyond the company’s control. However, Thai law does not explicitly state that force majeure excuses a contractual party from liability when they cannot perform an obligation.

The party who invokes force majeure will need to establish the following facts:

  • The event that prevents the party from performing the contractual obligation is force majeure and is not caused by the non-performing party;
  • It is not possible to perform the obligation during the force majeure; and
  • After the force majeure event concludes, performance is not possible.

Fulfilling these three factors would make a non-performing party likely to be excused from liability under force majeure. However, force majeure clauses are strictly and narrowly construed, and even if the COVID-19 pandemic or a government order under the state of emergency qualifies as a force majeure event, a party would only be excused if the pandemic or a subsequent order actually delayed or prevented the party from performing.

For example, in Supreme Court Case No. 5353/2552, the defendant purchased chicks and food for chicks from the plaintiff, and agreed to sell the grown chickens back to the plaintiff. The court considered that there were two contracts—one for the sale of chicks and food (with the defendant obligated to pay the price for these items), and the second for the sale of grown chickens from the defendant to the plaintiff. However, the outbreak of avian flu caused the government to order the culling of all chickens in the defendant’s possession. The court considered the avian flu to be a force majeure event, and the culling of the chickens made the defendant’s contractual performance impossible. Thus, the defendant was excused from the contractual obligation to sell the chickens to the plaintiff. However, the defendant’s obligation to pay the price of the chicks and food for chicks (or the monetary obligation) had not been made impossible, so the defendant was held liable for the outstanding price for chicks and their food.

Where performance would likely not be prevented, but merely rendered more difficult or expensive, it would not be excused. Often, the relevant question is whether the additional expense or difficulty would be so great as to make it effectively impossible for the party to perform. From the Thai court’s perspective, having insufficient funds to carry out an obligation is likely not reasonable grounds for releasing a party from a contractual obligation, and raising the issue of force majeure would not help. The court has ruled in many cases that shortage of funds cannot be considered force majeure because the funds should be prepared in the normal course of business.

The Importance of Timing

If force majeure can be demonstrated, the question of when it began will then need to be addressed, but that may not be as simple as one might expect, thanks to the dynamic evolution of COVID-19 and the differences in restrictions across the globe. For example, if performance was to take place in Wuhan, China, the force majeure would commence January 23, 2020, when the central government imposed a lockdown in Wuhan and other cities in Hubei in an effort to quarantine the center of an outbreak. However, if performance was based in Thailand on the same date, it may not be considered impossible because, at that time, the WHO had not yet declared the coronavirus disease a pandemic.

In summary, it is not enough to simply establish force majeure in order to excuse the non-performing party’s liability, as force majeure does not automatically release parties from their contractual liability unless they can establish that the contractual obligation is impossible—something that can have a high burden of proof, and be subject to variation depending on a range of factors.

Cross-border disputes often end with a judgment or arbitral award issued outside Thailand. When a party has assets or operations in Thailand, the key question becomes simple: will a Thai court enforce it? Thai law treats foreign court judgments and foreign arbitral awards very differently. Foreign court judgments cannot be recognized or enforced directly and must effectively be re-litigated. Foreign arbitral awards, however, benefit from a clear recognition and enforcement process under the New York Convention and Thailand’s Arbitration Act. Thailand’s Overall Approach Thailand does not have a general law or treaty that allows automatic enforcement of foreign court judgments. To rely on a foreign judgment, a party must initiate a new lawsuit in a Thai court, plead the claim under Thai law, and prove the case again. The foreign judgment can be used as evidence, but it is not binding, and the Thai court retains full discretion to reassess both the facts and the law. Foreign arbitral awards are treated more favorably. Thailand is a longstanding member of the New York Convention and has implemented it through the Arbitration Act. The act provides a straightforward process for asking a Thai court to recognize and enforce a qualifying award, without retrying the dispute, and subject only to limited refusal grounds. Foreign Court Judgments: Persuasive but Not Binding Although Thai courts do not recognize or enforce foreign court judgments, they may rely on them as persuasive evidence under certain conditions. Courts generally give more weight to judgments that are final on the merits, issued by a court with proper jurisdiction, and reached after proper notice and an opportunity for the defendant to be heard. Default judgments or rulings based primarily on procedural grounds carry less weight, and the ultimate relevance and weight are left to the court’s discretion. In practical

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’s Civil Court has issued a regulation targeting the use of artificial intelligence (AI) in the preparation of pleadings and other documents submitted to the court. Effective November 17, 2025, the regulation aligns with September 2025 guidance from the president of the Supreme Court, and aims to safeguard accuracy, transparency, and public confidence in civil adjudication. The regulation applies to all parties submitting pleadings or any documents to the Civil Court that are prepared using AI tools or contain AI-generated content. It subjects AI used for these purposes to strict requirements on verification, disclosure, and accountability. Core Obligations The regulation imposes four principal obligations: Lawyers who use AI remain subject to duties of honesty, responsibility to the court, professional standards, and legal ethics, including the duty to assess the appropriateness of the AI tool for the work. Parties and lawyers must verify the accuracy and completeness of all facts, legal provisions, and citations in AI-generated content before submission. Parties and lawyers must disclose to the court any AI-generated content by clearly marking the beginning and end of the AI-generated portion with prescribed statements (see below). Additionally, a certification confirming the use of AI must be provided at the end of the pleading or document, stating that AI was used for certain portions and that the party has reviewed and certifies the accuracy of factual and legal content. Parties and lawyers bear the same full legal and ethical responsibility for AI-generated content as they do for personally authored documents; they cannot evade responsibility or avoid liability by citing AI-related errors. Likewise, parties must ensure that any AI-generated content is truthful, accurate, and unbiased. Prescribed Disclosure Language Each instance of AI-generated content must be preceded by the statement “[The following content was prepared using artificial intelligence]” and must end with “[End
