A tourist services contract is one of the most common contracts concluded on the market of tourism services, which in general comprehensively regulates the relationship between a participant of tourist packages (a consumer, a traveller) and a professional entity (basically, although with some simplification, a tour operator). Proper stimulation of the relationship between professional and non-professional (consumers) entities should, therefore, be the priority task of the tourism policy, which can be achieved by using a wide catalogue of instruments, including legal acts. Problems with proper functioning of a contract cause dysfunctions, which, due to the universality of the agreement, can result in far-reaching negative effects. Of course, it is necessary to remember that the content of a tourist services contract is one of the most important elements determining the quality of the agreement on the market of tourist services. That is why, the study concentrates on the issue of contractual information (the information contained in the contract), because it is reasonable to indicate that the professional entities “communicate” with consumers also via the content of the agreement, which includes basic information about the provided services, and therefore, consumers should pay special attention to the analysis of that content. It is more than obvious that the lack of equality between professional and non-professional entities on any services market can be considered this market defectiveness, and hence can result in far-reaching distortions of competition. Defects often depend on the internal characteristics of the market. Therefore, the article first identifies the main characteristics of the tourist market (determined by the specificity of tourist products). Then, issues related to professional entitles’ information obligations, with a special emphasis on the content of a tourist services contract, are discussed in detail. The main considerations are divided into two areas: (1) comments on Directive 90/314 and the Act on tourist services of 1997; (2) comments on Directive 2015/2302 and the Bill on tourist packages and related tourist services.
