The procedural and organizational-tactical bases of the involvement of a specialist in a search in criminal proceedings on the appropriation, embezzlement of property or taking possession of it by abuse of official position are investigated. Data from official statistics testify to the low quality of investigations into official embezzlement in Ukraine. The main subjects investigating the criminal offense provided for in Article 191 of the Criminal Code of Ukraine are investigators of the National Police. Accordingly, a forensic specialist of the National Police or a forensic expert of the Expert Service of the Ministry of Internal Affairs is most often involved in the search in such criminal proceedings. Emphasis is placed on the mandatory participation of a specialist during the search in the investigation of official embezzlement with the aim of continuous video recording of its progress in the event that witnesses cannot participate. The factors that are guided by the investigator when determining which specialist should be involved in the search are highlighted. It was concluded that in the studied category of criminal proceedings, it is advisable to involve specialists from various fields in the search, whose functions will depend on the stages of the investigative (search) action. The joint actions of the investigator and the specialist at the preparatory, working and final stages of the search are revealed. The recommendation to involve in the search the specialist who participated in the previous procedural actions was supported.
