The widespread usage of construction contracts has led to an increase in Subcontracts, where the original contractor delegates their contractual obligations to another contractor referred to as a subcontractor. The cen tral question is: does the Civil Transactions Law regulate Subcontracts in the same way it regulates construction contracts? The importance of the research lies in the fact that it deals with subcontracting as one of the most widespread types of contracts. The importance of the research also lies in the lack of national research on the subject of subcontracting based on Omani law. Since the main issue of the research is the lack of regulation of the civil transactions law on the subcontracting contract and the provisions related to this contract, this research aims to study subcontracting and specifically the relation ship of the original contractor with the subcontractor in Omani legisla tion, Additionally, the study addresses critical issues, such as whether a subcontractor has the right to claim payment directly from the employer before the original contractor, and what are the subcontractor rights if they complete part of the work but are unable to finish the remaining tasks due to one reason or another. As a methodology, the researchers use descriptive and analytical approaches to elucidate this issue. They conclude with several findings, notably the lack of regulation of Subcontracts by Omani legislation. Consequently, the main recommendation was the necessity of regulating this type of contract.
