Introduction The principle of unjust enrichment has traditionally held a significant role within civil law traditions, serving as a core mechanism to deter parties from gaining an inequitable advantage at another’s expense. Its importance is especially pronounced in commercial legal conflicts, where multifaceted agreements, financial transactions, and service contracts frequently produce scenarios that strain conventional legal frameworks. The expansion of international trade, the rise of digital payments, and the emergence of sophisticated financial instruments have further complicated this area of law. Within Uzbekistan’s legal system, unjust enrichment is codified in the Civil Code; however, its practical use in resolving commercial disagreements is still evolving. The doctrine’s limited utility stems from insufficient legislative detail, divergent judicial approaches, and a general absence of comprehensive academic commentary. This paper aims to connect theoretical understanding with real-world application by analyzing the historical development, conceptual foundations, and dynamic evolution of unjust enrichment. It critically examines dominant legal perspectives, supports analysis through 73-son 2–to’plam Iyun-2025 Sahifa: 22 Ustozlar uchun pedagoglar.org both local and international case comparisons, and proposes targeted reforms suited to the legal and economic realities of Uzbekistan. 2.The Concept and Legal Foundations of Unjust Enrichment Unjust enrichment refers to a situation where a person gains a benefit at the expense of another without a legal basis. It is premised on the equitable maxim that no one should be unjustly enriched at another’s cost. In most civil law jurisdictions, including Uzbekistan, unjust enrichment is recognized as a non-contractual obligation that serves to restore financial equilibrium between parties. 2.1 Essential Elements The legal doctrine of unjust enrichment generally comprises the following four essential elements:  A party has received a benefit (enrichment);  Another party has suffered a corresponding loss (impoverishment);  There is a causal connection between the enrichment and the impoverishment;  These criteria are essential in evaluating unjust enrichment claims and in differentiating them from those based on contract or tort. Among them, the absence of legal grounds is frequently the most contested, particularly in commercial transactions where informal conduct or incomplete obligations may cloud the basis of the enrichment. 2.2 Types of Enrichment Unjustified gains can appear in many ways, such as receiving money, acquiring goods, obtaining services, or being freed from a debt. In business, common examples include overpayments, mistakenly delivered products, misuse of confidential information, or benefits retained after a contract is voided. Sometimes, enrichment happens unintentionally—for example, when a payment is missed due to an administrative oversight. 2.3 Historical and Doctrinal Roots Unjust enrichment, as a legal concept, can be traced back to Roman law. Central to its origin is the principle nemo locupletari debet aliena iactura—the idea that no one should profit from another’s loss. Over the centuries, this notion matured through the detailed development of condictio actions by legal scholars. It later found its place in the codified frameworks of various continental European civil codes. In the modern legal landscape, figures like Von Tuhr and Windscheid revisited and refined the concept, presenting it as a tool designed to address the legal voids left by contract and tort doctrines. 3.Dominant Theoretical Approaches to Unjust Enrichment Legal scholars and practitioners have developed several interpretative frameworks for understanding unjust enrichment.
