In the context of the instability of tour operators as key participants in the tourism market, issues related to the regulation of mechanisms and instruments for financial liability insurance of tour operator activities to protect the interests of tourists, whose numbers are rapidly growing in connection with the promotion and implementation of the national project “Tourism and Hospitality”, remain relevant. This article examines the key regulatory and legal aspects of the functioning of legal instruments that ensure the observance of the property rights of tourists in the sale of a tourism product and identifies key issues requiring immediate solutions and the attention of the legislator [10]. Particular attention is paid to the problem of the normative understanding of the term “tourism product” due to the discrepancy between the practical component of its implementation in the domestic tourism market and the established legal practice based on the experience of selling tourism services primarily in the field of outbound tourism [2]. An analysis of the functioning of traditional mechanisms for ensuring tour operator financial liability in the Russian system was conducted, and alternative innovative tools were considered, such as the introduction of a unified compensation fund (tourist tax), a mutual tour operator liability insurance society (MLIS), and others. The overall conclusion of the scientific study is the need to expand tour operator liability mechanisms and develop new flexible tools to reduce the risks of infringement of tourists’ property rights in domestic and inbound tourism. Effective consumer protection is a prerequisite for the sustainable growth of the tourism industry. This requires a comprehensive approach that includes not only financial guarantees but also clear procedures for resolving tourist claims as consumers.
