The purpose of the study was to identify the main models of organisation of the forensic system in Ukraine and to assess international experience in the field of expert support of justice, as well as to analyse ways to adapt modern world standards to national expert practice. The theoretical basis of the study was the documents defining the status and organisation of forensic experts in Ukraine, Latvia and the Czech Republic. The functions related to forensic examinations, examination, and seizure were analysed. It was revealed that the organisation of forensic expert activity in European countries is focused on creating an effective system of expert institutions and ensuring optimal conditions for conducting examinations by qualified specialists who are appropriately accredited and included in the official registers of forensic experts. It was emphasised that in Ukraine there is a mixture of two approaches to structuring forensic expert activity. The advantages of such a mixed model include harmonisation of forensic examinations, standardization of expert methods, accreditation of forensic laboratories and publicity of the register of forensic experts. The author substantiated the need to integrate the Ukrainian system of expert support of justice into the international context and to participate Ukrainian forensic institutions in international organisations that bring together foreign expert institutions. This will help to improve the procedures for the participation of forensic experts in justice. The author proposed to establish a single body – the National Service for the Provision of Forensic Expertise, which will be subordinated to the Ministry of Justice of Ukraine. Thus, the practical significance of the study is that its results can be used to centrally address the problem of methodological and information support of expert activity, which in turn will improve the organisation of forensic activities in Ukraine
