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

Litigation has its place in resolving business disputes, but it is often time-consuming and costly. In Thailand, a straightforward civil case can take a year or more to reach judgment at first instance, and appeals can extend that timeline further. Court filing fees are tied to the value of the claim, typically amounting to around two percent for claims up to THB 50 million, before accounting for attorney fees, translation costs, expert work, and the internal time that management must devote to the case. Against this backdrop, Thai law provides an alternative pathway for parties to attempt resolution before filing suit, and Thai courts commonly encourage mediation as part of the dispute-resolution process. Specifically, prelitigation mediation is a court-supervised process designed to facilitate confidential settlement discussions at an early stage. Participation is voluntary and requires the consent of both parties. The process does not replace litigation but is available in parallel as an initial step for interested parties. If the parties reach an agreement, the settlement can be recorded as a consent judgment that is directly enforceable in Thailand. If no settlement is reached, the parties retain their full right to proceed with a court claim. Reasons to Consider Prelitigation Mediation Prelitigation mediation can offer several advantages. It may shorten timelines from months or years to just weeks, reduce legal costs, and keep discussions confidential. It also allows parties to pursue practical, business-driven solutions or tailored remedies that address their specific needs—outcomes that may not be available through traditional litigation. To facilitate this process, under Thailand’s Civil Procedure Code, parties may petition the court to initiate prelitigation mediation before filing a suit. If the opposing party agrees, the court appoints a mediator to work with the parties under established mediation rules. In such a scenario, there are no court
