The article analyzes the legal category «other forms of ownership». The author critically evaluates the allocation in the Constitution of the Russian Federation and other laws, along with private, state and municipal, other forms of property. The lack of a clear understanding by the legislator of the essence of the category under consideration gives rise to inaccuracies in the formulation of legal concepts in acts of the Constitutional Court of the Russian Federation and the Supreme Court of the Russian Federation. Courts confuse the concepts of «form of ownership» and «ownership rights». The work also analyzes the positions of scientists regarding the disclosure of the content of the legal category under consideration. The author comes to the conclusion that it is necessary to exclude from the current legislation the rule of law indicating the presence of other forms of ownership.
