Abstract

The legal concepts of expiration and termination in contract law, though often used interchangeably in practice, possess distinct theoretical and practical implications that significantly affect contractual relationships. This paper undertakes a critical reassessment of the boundaries between expiration—the natural conclusion of a contract upon fulfillment of its terms—and termination—the active cessation of contractual obligations prior to their stipulated end. Through doctrinal analysis, comparative legal perspectives, and examination of recent judicial decisions, this research elucidates how the ambiguity between these concepts can create legal uncertainty, especially in complex commercial agreements. The paper proposes a refined legal framework that distinguishes expiration from termination in both statutory and common law contexts, providing clarity for courts, practitioners, and contracting parties. The study contributes to contract theory by enhancing precision in contractual language and advocating for uniform interpretive standards in international contract practice.
