In lawmaking, there are situations when draft normative legal acts do not reach the entry into force stage. In some cases, the reason is non-compliance with formal requirements, poor elaboration of the act, and in some cases, incorrect calculations or inexpediency of expenses. A large number of changes are often made to already adopted regulations in order to correct previously incorrect decisions, as well as adjust the financial security of their implementation. These situations are aggravated by various circumstances, including, for example, difficult economic conditions and the international situation, calling for a compromise between costs and regulatory effectiveness. Such problems and circumstances show the importance of studying the cost of legal regulation, one of the aspects of which is the study of the normative consolidation of rules regarding the determination of the cost of law-making and the implementation of accepted norms. Based on this, the subject of this study is normative legal acts that establish the need to study and fix the costs of law-making and the costs associated with planning the implementation of norms, as well as the requirements for the content of the financial and economic justification as an accompanying document of the draft normative legal act. The author comes to the conclusion that despite the significant importance and the real need for regulatory legal consolidation, the assessment of the costs of lawmaking is not regulated anywhere. On the contrary, the requirements for estimating the planned costs of legal realization are regulated in a variety of subordinate regulatory legal acts and in most cases these provisions are duplicated. Regulatory impact assessment and actual impact assessment are currently carried out in relation to business entities and other economic activities and only in relation to costs arising in connection with the fulfillment of regulatory requirements.
