Abstract: The subject of the study is the problem of the identification of a consumer in a contractual relationship. The author emphasizes the fact that although there is a great number of research studies, there is no single strategy of identification of a consumer in a contractual relationship. The identification of a consumer in a contractual relationship is of great importance in the civil circulation, as a lawmaker associates specifically this status with the emergence of appendant rights. The article also examines the issue of the legal body's possibility to serve as a consumer. The study investigates the concept of consumer interest. The author provides an analysis of the key dogmatic approaches to the identification of a consumer in a contractual relationship. Also, she analyses the concepts given by the lawmaker and strategies developed under judicial practice. The article analyzes the emerging of an individual legal regulation of the contracts involving the participation of a consumer within a historical context. The author applies such methodological methods as analysis, synthesis, comparative and legal, technical, and logical methods. The author uses both general scientific and special-judicial research methods. The author draws a reasonable conclusion that a lawmaker has poorly observed the concept of a consumer. Judicial practice and the doctrine do not have a single approach to the criteria of identification of a consumer in a contractual relationship. The author suggests developing the concept of consumer interest as a possible criterion of identification of a consumer in a contractual relationship. Moreover, the author suggests introducing an additional feature of a consumer into the law.
