The study reveals some of the phenomenon of legal force features, which is an integral element of regulatory legal acts, as well as contracts, electronic documents that act as regulators of public relations. The purpose is to determine the methodological approaches with the help of which it is pos-sible to study this phenomenon more fully, as well as to identify the short-comings of the existing approaches. The dialectical-materialistic method, general scientific methods, special legal methods are used as methods. In the course of the research, we turn to such methodological approaches as histori-cal, logical, hermeneutic, comparative, systemic, synergistic, humanistic, cy-bernetic, structural, functional. A brief description of them is given (the fea-tures are determined, the views of legal scholars on these methodological ap-proaches and the applicability of such approaches in relation to the study of the phenomenon of legal force are reflected). We come to the conclusion about the insufficiency of the currently existing research methodological ap-proaches in relation to the category of “legal force” and determine some prospects for the development of this topic. We prove that methodological approaches allow us to study not only the features of the category of “legal force” (classification, purpose, etc.), but also the specifics of acts, documents, the process of their adoption, application.
