Introduction. The digital transformation of modern society has predetermined the emergence of new socio-economic phenomena, the legal registration of which occurs remotely, with the help of modern information technologies, most often objectified in the form of mobile applications. Theoretical analysis. In this format, car sharing legal relations arise, the parties to which enter into the appropriate contractual relationship, and also carry out business communication using a mobile application. Despite some digital innovations that ensure the digitalization of civil turnover (including equating the electronic form of a transaction to a written one, positivization of digital rights, smart contracts, etc.), these innovations are not sufficient to create a special legal regulation of a car sharing transaction. Empirical analysis. One of the specific features of such a transaction should be recognized as its conclusion, as well as execution through the use of modern information technologies (mobile application). This study presents a detailed analysis of this feature of a car sharing transaction. Results. In connection with the demand for car sharing services, some general proposals for improving the current legislation in the studied area have been formulated. Special attention should be paid to car sharing legal relations by developing both a special federal law dedicated to this service and a separate civil law contractual structure – per-minute rental of vehicles.
