The article is dedicated to the examination of the existing system of legal regulation of information activities of prosecutor’s offices in Ukraine, taking into account the changes that these bodies have undergone in the reform process. The study is based on the ideas and achievements of local researchers regarding the information support of the prosecutor’s office and the analysis of the relevant provisions of the legislation in force. Supporting the view that the information and legal support of the Ukrainian prosecutor’s office is based on both basic and special legislation, the author proposes the following main levels governing, directly or indirectly, the information and legal support of the Ukrainian prosecutor’s office: 1) international legal acts that guarantee the person’s right to information; 2) the general level of the state; 3) the specialized state level (Ukrainian Law “On Prosecutor’s Office” and the regulations underlying the information legislation of Ukraine); 4) regulations aimed at governing legal information relations within the prosecutor’s office (orders of the General Prosecutor’s Office of Ukraine, etc.). Particular attention is paid to a brief analysis of the regulations, which are assigned to each level of regulatory support for the information activities of the prosecutor’s office. It is stated that the most significant changes in recent years are attested at the specialized state level and at the levels of normative acts of subordinate regulation. At the same time, the author concludes on the insufficient level of updating the regulatory, normative and legal support of the information activities of the Ukrainian prosecutor’s office, forecasting the increase of the dynamics of this process, taking into account the trends of state reform in the context of total computerization.
