The ownership of real estate in Croatia is recorded in public land registers and the public cadastre. With the Croatian transfer to an information society, it was recognized that manual bookkeeping of land registers was to be superseded with the use of modern, information-communication technologies (ICT). One of the main components within the wider framework of justice reform around the beginning of the 2000s was the implementation of modern information-communication technologies and information systems, including the verification of register books, the computerization and digitization of relevant data and the transfer from manual to digital documentation. The Joint Information System (ZIS) was a product of this reform, and it represents a centralized system which holds the database of land registers and cadastres. The entire procedure demanded large financial funds, and it was financed by the International Bank for Reconstruction and Development (IBRD). The implementation of the ZIS sped up the process of registering real estate, raised the level of legal security, rationalized, and simplified procedures, and greatly increased the speed and quality of the service. This paper explains the example of a location within the city of Zagreb, itself divided into fifty cadastral districts, which points to a divergence between the division of local and municipal government in Croatia and the division into cadastral districts. Utilizing the practical micro location of the Point Shopping Centre within Zagreb, the practical role of the ZIS is explained.
