Abstract: The subject of research in this article is the processes of legal regulation and the law enforcement practice of establishing, changing and clarifying the borders between the subjects of the Russian Federation. The object of this research is the public relations pertaining to the territory and borders of the subjects of the Russian Federation. Special attention is devoted to determining the general trends and legal issues in this area, starting with the terminological differences of the procedures concerning interregional borders and ending with the search for the solutions to the practical and legislative establishment of the territorial status of the subjects of the Russian Federation. Analysis is conducted on the federal and regional legislation on the issues of borders between the subjects of the Russian Federation, revealing the problems and limitations in realization of some recommendations of federal authorities in this area. Arguments are provided on the balanced approach towards delineation of the processes of establishment, changes and clarification of the borders between the subjects of the Russian Federation, as well as unallowability of destabilization of the situation. It is proved that the borders between the subjects of the Russian Federation are usually established and recognized, but in number of instances require improvements in their description, clarification, as well as potential changes. The author proposes a concept of special federal legislation that would regulate border issues between the subjects of the Russian Federation, as well as clarification of the procedures of changing the borders of the subjects of the Russian Federation.
