This article notes that the legal regulation of outsourcing in Ukraine and abroad is based on specific laws and regulatory acts. It analyzes that Ukrainian outsourcing companies provide about 80% of their services to foreign clients, indicating offshore outsourcing. Currently, numerous highly developed countries are the most active consumers of Ukrainian outsourcing. It is identified that the absence of a definition of outsourcing contracts in Ukrainian legislation poses a significant obstacle to the activities of outsourcing enterprises in Ukraine. Reforming the legislation in the field of service provision, particularly Chapter 63 of the Civil Code of Ukraine, is necessary to create regulatory conditions for outsourcing activities.Emphasis is placed on the creation of a separate regulatory legal act that considers the specifics and characteristics of outsourcing as a type of economic activity. It is argued that aligning with general principles of international law should form the basis for developing legal norms in the field of Ukrainian outsourcing.The article characterizes that the activation and strengthening of the role of the service sector in Ukraine's relations with other countries necessitate integrating national legislation with international norms. In this context, the General Agreement on Trade in Services (GATS) is a significant source that establishes the fundamental principles of international trade in services: most-favored-nation treatment, transparency of regulation, mutual recognition of qualifications, and rules regulating monopolies and competition. The Civil Code of Ukraine is analyzed, underscoring that the concept of outsourcing is not defined, which similarly applies to the Commercial Code. However, it is referenced in specific regulatory acts, notably in paragraph 6 of Part 1 of Article 2 of the Law of Ukraine "On Capital Markets and Organized Commodity Markets."It emphasizes that the concepts of outsourcing discussed in the article define the organizational nature of outsourcing contracts, characterizing the scope of their implementation, as well as the tools and expected outcomes of implementation. Simultaneously, integrating outsourcing into an organization's activities enables it to make organizational changes aimed at enhancing efficiency through minimal costs. Introducing such an effective organizational tool into the country's economic activity requires proper legal regulation.
