Problem setting. The problem of legalization (laundering) of money and other property acquired by criminal means is of great importance for Ukraine, because the criminalization of the economy is the main threat to the economic security of the state. In order to successfully combat this negative phenomenon, it is necessary to constantly develop and improve the processes of identification and analysis of financial transactions that are the objects of financial monitoring. Detection of such transactions requires clear criteria and indicators that allow you to quickly and accurately identify among the range of financial transactions those related to money laundering. The list of criteria and indicators of suspicion of financial transactions is large and sometimes ambiguous in terms of its interpretation and application. This issues is important because it is about the scope of law, the subjective rights of participants in financial transactions, the ownership of such persons in their assets and the level of trust in entities that provide financial and other services. The purpose of the research is to study the legal norms in the field of establishment and classification of financial monitoring objects – types of financial transactions depending on the criteria and indicators developed by the subjects of state financial monitoring and supplemented by the subjects of primary financial monitoring.
