The article presents the author’s approach to common definitions and theoretical- legal content of the legal process. Approaches to the problem of relations between concepts «procedure» and «process» have been considered. Under the procedure, the author understands the normative rule, incarnated in the legal regulation of social relations, thereby necessitating the allocation of traditional procedural branches. Auxiliary legal procedures largely determine the quality of their response and the system demands placed on them. The author believes that the legal process is the most profound concept and proves the correctness of «broad» approach to understanding the legal process. The essence of the «broad» concept of the legal process is that the function of procedural law is not limited to regulation and enforcement resolution of civil disputes, that in addition to the criminal and civil processes in the material, there are many branches of law procedural rules and institutions that underpin the activities on the application of the substantive law in all industries.
