The land register system, which in Italy exists only for the old Austrian territories which were assigned to the Italian Kingdom in 1919 after the First World War, has established, by various national and regional laws, a specific system for the entry of rights and obligations relating to immovable property in public registers.

In Italy, therefore, the land register right exists only for the region of Trentino-Alto Adige and for parts of the region of Friuli-Venezia Giulia.

The main difference with the system of the property register is that only those rights which are actually registered in the land register actually exist. The incorporation of a right therefore has a constitutive character.

As a result of this different legal regime, different case law applies.
