The Hellenic Cadastre is a unified and constantly updated system of information that records the legal, technical and other additional details about real estate properties and the rights on them; this information is kept under the responsibility and guarantee of the State.

The development of the Hellenic Cadastre aims at the creation of a modern, fully automated real estate property record, whose details are of an evidentiary nature, ensuring the best publicity and security of transactions.

It is a significantly more modern and complete system than the old system of Registrations and Mortgages supported by the Land Registry Offices. Specifically, the Hellenic Cadastre:

1. Records all deeds that establish, transfer, change or abolish rights on properties on a real property-centred basis. Thus, everything becomes simpler and more definite.
   
   
2. Guarantees all legal details it records, since every deed is registered only after its lawfulness has been checked, meaning that no deed is registered if the transferor is not the person that the cadastre shows to be the beneficiary.
   
   
3. Records the geographical description (shape, location and size) of the property too.
   
   
4. Unveils and systematically records the State real property for the first time in contemporary Greece.
    
   
5. Records the rights evoking from usucaption, which, especially in the province, may constitute the most usual way of ownership acquisition due to the informal nature of transactions.
