The scientific article examines questions regarding the naked role of legal constructions in rule-making activity. We can point out that it is the legal construction that plays its main role as one of the most important means of legal technique. We propose to consider the legal construction in the prism of rule-making activity. They are considered as a conceptual form of legal thinking, which can be expressed in a system of norms that specify a specific mechanism of legal regulation or its separate element. On the basis of the above, the definition of legal structures and their main role in rule-making activity is proposed. Legal constructions are a single and independent element of legal technique. We can note that there is currently a high level of scientists studying the role of legal constructions. This applies mainly to branch disciplines, and not to general theoretical research. Recently, new research on this role of legal construction is based on the modern views of scientists. New reasons for the origin of legal constructions and their main role are proposed. We can see that there are no clear opinions about the origin of the role of legal constructions.
 Thus, we propose to consider the latest formation of concepts and their origin and to pay special attention to the definition of the role of constructions in rule-making activity. Attention is paid to the current topic of jurisprudence, related to the process of the defined role of constructions of legal activity with a practical component. The scientific novelty consists not only in the analysis of domestic literature, regarding the concept and the main role of legal constructions, but also in the latest views on this definition. At the same time, the problems of legal constructions until now have mostly sectoral (civil, criminal, administrative, family, financial, tax, social security, etc.) «coloring», which characterizes most of the research from the practical side.
