The thesis discusses tourist agencies and their status and contracts related to Croatian legislation. Tourist agencies are commercial law entities whose principal activity consists of organizing and entering into agreements, agreements related to tourist accommodation at a certain destination, and offering other services to their clients. The activities of tourist agencies include informative - consulting, mediating, the role of tour operators, and other various tasks such as exchanging currencies. There are several types of tourist agencies including specialized agencies such as those operating as retailers, those operating as wholesalers, independent, and dependent. An important name among tourist agencies is that of Thomas Cook, who organized the first trip in the 19th century. Associations such as UHPA (Udruga hrvatskih putničkih agencija; Association of Croatian Travel Agencies) exist in order for tourist agencies to protect their interests and improve their business. Associations that operate on an international level are UFTAA, WATA, ASTA, IATA, and others. The main contents of tourism agreements are tourism services regardless of the parties entering into agreement. Laws that protect tourists staying in Croatia are the Consumer Protection Act and the Law on Tourism, which ensure the protection of tourists. Agreements which agencies enter into are divided into those entered into with service users and those entered into with service providers. Agreements between agencies and service users are divided into agreements on travel organisation and intermediary travel agreements. Agreements between travel agencies and service providers are divided into agency agreements on hotel services, agreements on engaging catering facilities, agreements on leasing catering facilities, and agency agreements between the hotel representatives and hoteliers. Tourism agencies must maintain their liquidity by achieving clients’ trust and through effective and high quality travel organisation.
