The paper explains the issue of establishing a maritime domain cadastre and the importance of
establishing the boundaries of maritime domain. Particular importance is given to the clear definition
of the concept of maritime domain in order to make it clear what area can be declared a maritime
domain and why and what is its spatial coverage. Legislation has tried to establish a maritime cadastre
as a separate part of the cadastre, but it has not yet been achieved. Today, the maritime domain and
its boundaries are entered in the land registers kept by the municipal courts.
The authors consider it important to initiate the process of revision of Maritime Domain and Seaports
Act (hereinafter: MDSA), adopted in 2003, which has changed several times, but without resolving
the open issues of maritime domain management. This is especially important in order to avoid the
misuse and misappropriation of maritime domain and to harmonize the activities of coastal counties
in the process of establishing the boundaries of maritime domain.
