Land registry law is a branch of law that deals with the recording and management of real estate rights. Essentially, the REAL ESTATE office is an evolution of the MORTGAGE GUARDIANS that operate in the country. However, the operation of cadastral offices is governed by a complex complex of provisions that provide for strictly formal procedures. It is noted, for example, that the failure to declare the right of ownership during the land registration leads to the registration of the property as "UNKNOWN OWNER" and subsequently, after the expiration of the prescribed period, the property becomes the Greek State.
