To date, the terms "public service in the sphere of land relations" and "municipal service in the sphere of land relations" used in science and legislation have no definition. The lack of terminological certainty leads to an ambiguous understanding and inaccuracies in the research conducted, and in law enforcement practice it can become a source of violation of the rights and legitimate interests of citizens. The author considers approaches to the definition of state municipal (services), including public services. The division and classification of state (municipal) services is investigated. The division into spheres allows us to identify many social relations, among which is the sphere of land relations.

It is established that through state (municipal) services in the field of land relations, the land function of the relevant public authority is realized, albeit partially. The author formulates the concept of state (municipal) services in the field of land relations.
