The purpose of the articleis to submit the proposals for improving the legal regulation of the tacit cooperation as the system of operative-search and criminal procedure legislation of Ukraine’s norms which form the relevant legal institution. Methodology. The methodological toolkit is chosen taking into account the purpose, the specifics of the object and the subject of the study. Its basis is general dialectical method of scientific cognition of real phenomena and also their connections with practical activity of the operative-search units and bodies of pre-trial investigation. Special methods of research, used in the article, are the methods of systematic analysis, comparative-legal and modelling ones. With the aim of evaluation of the research’s results the questionnaires of 1000 operative workers, 1000 investigators are held. The theoretical basis of the study is performed by the latest studies of native and foreign scientists who work in this specific field. Scientific novelty. It is grounded that the main problem of the tacit cooperation’s legal regulation is the absence of systematic character. It is quite possible to create such a systematic nature by amending the legislation specifically in the sphere of tacit cooperation. These changes and amendments have already been formulated (new versions of Articles 11, 13 of the Law of Ukraine “On Operative-Search Activity” and Article 275 of the Criminal Procedure Code Have Been Proposed). Conclusions. With the aim of providing the systematic character to the mechanism of the tacit cooperation’s legal regulation changes and amendments of the national legislation must be introduced. The usage of the two possible approaches is possible while drafting such changes and amendments. The first one (tactical) involves drafting of the proposals keeping in mind the contemporary state of the operative search activity and criminal procedure’s legal regulation and introducing changes and amendments as to the tacit cooperationspecifically. The second approach (strategic) includes the introduction of proposals as to the settlement of the tacit cooperation’s issues in the content of significant reformation of the operative-search activity and pre-trial investigation’s legal regulation
