The aim of this article is to point out the historical development and importance of the depository institution as well as the need for regulation in the Croatian legal system. Depositum, is a bilaterally incompletely binding bona fidei contract by which the depositor gives his movable property to the depositary for safekeeping, and the depositary undertakes to keep the thing and return the thing after the expiration of the term or at the depositor's request. Depositum is very widespread in use both legally and economically. The paper presents a historical cross-section of the origins of the institute, which shows the influence of the Roman Empire on the Croatian legal system as well as its continuity and permanence. The deposit is based on a relationship of honesty and trust, both between the contracting parties themselves and the entire legal system. Roman law served as the basis for upgrading deposits in modern legislation. In addition to the regular form of depostium, there are three special types of depostium that are also discussed in this paper, namely depositum irregulare, depostium miserabile and depostium in sequestrem. In addition, the work included a quasi-delict actio furti et damni adversus nautas, caupones et stabularios, which in the Croatian legal system means a catering pantry, which is very widespread today because it is a Croatian tourist country. Accordingly, it is necessary to draw the attention of caterers and guests to the legal provisions concerning both their rights and their obligations. The caterer should know what his obligations and responsibilities are regarding the things he receives from the guest for safekeeping in his catering facility, and the guest should know what his rights are regarding bringing things into the catering facility or handing them over to the caterer for safekeeping. In conclusion, Roman private law had a wide impact on modern legislation, ranging from the regular form of the depostium to regulation and its special types.
