The article analyzes the legal regulation of the issuance of a certificateof the right of a surviving spouse to temporary use of a vehicle, introduced into the Fundamentals of the legislation of the Russian Federation on Notaries (art. 75.1) from August 30, 2025. The conditions for granting this right are considered, including the need to confirm the fact that the vehicle was used by the survivingspousebefore the death of the testator and the requirements for the submitted documents (vehicle registration certificate, vehicle passport, CTP policy). The authorreveals the socio-legalconditionality of the introduction of thisnormas a measure to support the relatives of the deceasedandensure the stability of the familystructure,andalsocompares the regime of legalregulation of the use of vehicles and real estate in hereditary legal relations. Special attention is paid to the conflictbetween the termination of stateregistration of a vehicleafter the death of the owner (in accordance with Federal Law No. 283FZ of 08/03/2018 and the Administrative Regulations of the Ministry of Internal Affairs of Russia) and the need to preserve the possibility of itsuse by the surviving spouse during the registration of inheritance rights. The paper identifies gaps in legal regulation, in particular, the lack of norms defining the scope of the surviving spouse's powers in relation to the disposal of the right to use the vehicle (including the possibility of transferring the right to thirdparties). Based on the literal interpretation of Article 75.1, it is concluded that the right of temporary use is reserved exclusively for the surviving spouse, while there are no legally established restrictions on the admission of other persons to management. The study substantiates the expediency of removing the restriction that binds the rule exclusively to cases of death of a person in connection with participation in a special military operation, and suggests extending the mechanism of temporary use of a vehicle to all surviving spouses, regardless of the grounds for the death of the testator. At the same time, the article outlines the potential risks of implementing the proposed legal structure, in particular, the possibility of damage or loss of a vehicle, which may lead to a violation of the property rights of other heirs.
