The article raises the following topical problems currently inherent in the institution of real estate in theRussian Federation: the unsuccessful legal definition of a real estate object, enshrined in Art. 131 of the CivilCode of the Russian Federation; qualification of objects as immovable and, accordingly, delimitation of themfrom movable ones; the emergence of objects with a controversial legal regime; the need to move from themodel of “plurality” to the model of “unity” of real estate objects. Also, the authors of this article analyzea number of approaches aimed at resolving the above problems and the possible consequences (both positiveand negative) of their implementation in practice, put forward their views and offer their own solutionto these problems. A variant of the legalization of “disputable” objects is proposed by introducing the rightof construction into the civil law of the Russian Federation as a limited property right to use a land plot withthe extension of this right to everything that is being built on such a land plot. The examples of legislativeregulation of the right to build in the civil law of pre-revolutionary Russia are considered, the elements of theright to build in the current law of the Russian Federation are revealed.
