Abstract: In order to carry out the tasks facing the criminal law, norms are provided in advance that have an encouraging character, but at the same time stimulate law-abiding behavior in the form of stopping preparations for committing a criminal act. Such an example is the institution of voluntary refusal to commit a crime and bring it to an end both alone and in complicity. At the same time, this category makes it possible to achieve one of the goals of criminal law – the prevention of crime, however, provided that the voluntary refusal becomes voluntary, timely and final. The subject of the presented research is the criminal law norms governing legal relations related to the voluntary refusal of complicity in a crime. The purpose of the study is to analyze the features of voluntary refusal to participate in a crime.The scientific research work analyzes the concept, signs and criminal law significance of voluntary refusal to commit a crime in complicity. The results show that group crimes, due to their prevalence, require a deeper study and development of theoretical foundations, legislative regulation and practical aspects for the correct legal assessment of such acts. The scope of the results is aimed at developing a separate legal norm devoted to the peculiarities of voluntary refusal. The scientific novelty of the study is expressed in the identification of special patterns and problematic aspects in the field of differentiation of voluntary refusal to commit a crime by the organizer, perpetrators and other accomplices.The conclusions emphasize the need to introduce a separate legal norm that will more effectively regulate the legal aspects of complicity, avoid mistakes in qualifying the voluntary refusal of accomplices from completing the crime, as well as ensure justice when bringing to justice participants in a group crime.
