The importance of tourism for the economy of a country requires a special arrangement of tourism and a quality product or service in order for it to achieve sustainable growth and development. Tourism has become an increasingly growing branch of the economy in the modern world. In tourism, the main stakeholders are the tourist, intermediaries and service providers. The relationship between these stakeholders is regulated by a contract, and this thesis will deal with the types of these contracts and their importance for the development of tourism. These contracts are signed in order to be able to regulate their relations and ensure the fulfilment of requirements on both sides. Thus, there are contracts between service providers and direct users, contracts between direct users and travel agencies, contracts between travel agencies and service providers, and some auxiliary contracts that facilitate the provision of tourist services.
