The scientific article describes the concept and essence of forensic support of criminal proceedings, defines the levels, directions and forms of its implementation. It is substantiated that forensic support is realized during the investigation and prevention of criminal offenses, as well as the judicial review of criminal proceedings (cases) using forensic means, methods, techniques according to certain levels, directions and forms. The levels of forensic support of criminal proceedings are distinguished, namely: local; regional; state; international. Considering the established system of forensics, according to which the development of theoretical foundations and practical recommendations of forensic support is based on the provisions of the general theory of forensic science, forensic techniques, tactics and methods, three main areas of forensic crime are defined: forensic. In this case, the general theory of forensic science is of methodological importance for the formation of their scientific foundations. According to the mentioned directions, the main forms of forensic support of criminal proceedings are distinguished: – in the direction of technical and forensic support: the use of technical means and methods of detecting, fixing, collecting, investigating the traces of crime, other forensically relevant information, including through the use of special knowledge, involving specialists in investigative (investigative) actions; fixing the course and results of investigative (investigative), court actions; maintaining criminal registration and forensic records systems; involvement of experts and carrying out of expertise; – in the direction of tactical and criminalistic support: improvement of existing and development of new tactical techniques and their complexes; formation of tactics of investigative (search) actions; – in the direction of methodological and forensic support: development of new methods of investigation of criminal offenses (according to the criminal law and forensic classification); formulating recommendations to increase the effectiveness of the method of investigation of certain types (groups) of criminal offenses. These levels, directions and forms of forensic support should be considered in the scientific and practical aspect, which consists in creating the scientific basis of the tools, methods and techniques used the formation of practical recommendations for their application. The unity of theory and practice ensures effective achievement of the set goals in the system of forensic support of criminal proceedings.
