Named contracts in tourism according to the Obligations Act are part of commercial law, which represents one of the most dynamic branches of law that is directly related to tourism. The modern development of technology and knowledge in tourism leads to the constant emergence of new legal relationships where outdated relationships must be adapted and corrected in parallel. In tourism, there are two types of contracts: 1) "unnamed" contracts - contracts that are not regulated by legislation but by business customs; in Croatian law, for example, direct, agency and part of allotment contracts on hotel services are governed by the Special Provisions in the Hospitality Industry and 2) "named" contracts - contracts that are regulated by national legislation; in Croatian law, these are the allotment agreement (1), the travel arrangement agreement (2), the travel agency agreement (3) and the hospitality deposit agreement (4). Contracts regulated in the Obligatory Relationships Act - named contracts in Croatian tourism law - are used to conduct business between the parties to the contract. These are contracts that are often used in the tourism sector, and for this reason they have their own categorization. Each named contract has its own specifics that describe how the course of business exchange should take place, and what will happen in cases of non-fulfillment of obligations by a certain contracting party or in the event of unexpected situations. These contracts can be concluded between service users and travel agencies, and between travel agencies and service providers. Named contracts in tourism from our ZOO do not have the same contractual parties that conclude them. In cases where the contract is concluded between service users and travel agencies, it is an allotment contract, while in the case of a contract between travel agencies and service providers, it is a catering contract, an organized travel contract and an intermediary travel contract.
