Administrative and Legal Principles of Formation and Maintenance of Registers in the Social Protection System of Ukraine

The article explores the administrative and legal principles for the formation and maintenance of state registers in Ukraine’s social protection system. The regulatory and legal framework governing their operation is analyzed, including the Constitution of Ukraine, relevant laws, and subordinate regulations. The study examines the key information resources of the Unified Social Information System (USIS), such as the Register of Providers and Recipients of Social Services, the Register of Housing Subsidy Recipients, the Register of Persons Entitled to Benefits, the Disability Data Bank, the Internally Displaced Persons Accounting System, among others. The purpose of the article is to provide a comprehensive study of the administrative and legal framework for the formation and maintenance of registers in the social protection system of Ukraine, to analyze the functioning of key information systems and registers, and to determine the feasibility of introducing a sectoral register of social protection registers. The methods used include systems analysis, formal legal, and comparative legal methods. The article critically examines the universal concept of creating a unified state «register of registers», which raises concerns regarding its application in the social sector, given the specific legal requirements for the processing of personal data. As part of the research novelty, an alternative approach is proposed – developing a sectoral register of social protection registers. This model is aimed not only at improving management efficiency and data exchange between subsystems but also at enabling integration with information systems in other sectors (such as healthcare, education, and environmental protection), while preserving the sectoral specificity of social protection. The findings can be used in drafting regulations governing the structure and operation of information systems in the field of social protection and in implementing digital solutions in public administration.
