THE PROHIBITION OF CONTRACTUAL MODIFICATION OF CIVIL PRESCRIPTION UNDER THAI LAW

Abstract

This article examines the legal issues arising from the prohibition against contractual agreements to shorten or extend prescription periods under Section 193/11 of the Civil and Commercial Code of Thailand. The study is prompted by the observation that, although the provision is intended to safeguard public policy and prevent unfair exploitation between contracting parties, its absolute prohibition may be inconsistent with the principles of private autonomy and freedom of contract, particularly where the parties possess relatively equal bargaining power and legal standing. Furthermore, Thai law does not provide a legal framework permitting parties to modify prescription periods under appropriate conditions, despite the fact that certain special statutes and several foreign legal systems recognize such contractual modifications subject to limitations designed to protect public interests and weaker contracting parties. This discrepancy reflects a legislative gap in Thai law that warrants further examination and legal reform.

This study employs a qualitative research methodology based on documentary research. It analyzes the relevant provisions of the Thai Civil and Commercial Code, decisions of the Supreme Court of Thailand, scholarly legal opinions, and comparative legal materials, including the UNIDROIT Principles of International Commercial Contracts (PICC), the Principles of European Contract Law (PECL), the French Civil Code, the German Civil Code (Bürgerliches Gesetzbuch: BGB), and the Multimodal Transport Act B.E. 2548 (2005), which constitutes a special statute under Thai law. These sources are examined to evaluate the appropriateness of reforming the current Thai legal framework.

The findings indicate that the absolute prohibition against contractual agreements to shorten or extend prescription periods under Section 193/11 imposes an excessive restriction on freedom of contract in certain circumstances and is inconsistent with the modern development of private law, which seeks to achieve an appropriate balance between the principle of party autonomy and the protection of public interests. In many jurisdictions, contractual modification of prescription periods is permitted, provided that it is subject to clearly defined conditions and limitations designed to prevent unfair bargaining practices and to preserve legal certainty in private legal relationships.

Accordingly, this article proposes that Section 193/11 should be amended to permit contracting parties to agree upon the shortening or extension of prescription periods within limits prescribed by law. Such reform should also establish specific exceptions for certain categories of claims and for contracts involving consumers or parties with unequal bargaining power. This approach would promote a more appropriate balance between freedom of contract, the protection of weaker contracting parties, and the legal certainty of Thailand's civil and commercial legal system.
