Greece's national land registry — the definitive record of property ownership, boundaries, and rights, gradually replacing the older Mortgage Registry (Hypothikofilakio) system.
The Ktimatologio (Κτηματολόγιο) is Greece's national land register — the unified property registry that records legal ownership, property boundaries, and all rights, charges, and encumbrances over real estate in Greece. It is administered by EKXA S.A. (Greek Cadastre) and is progressively replacing the older, fragmented Mortgage Registry (Hypothikofilakio) system. The Ktimatologio represents a fundamental modernisation of Greek property law, introducing a guaranteed, state-backed registration system for the first time in Greece's history.
Unlike some other European land registries, the Greek Ktimatologio records both the legal title AND the spatial data (cadastral map) for each property in a single integrated system. Each property is assigned a unique cadastral identifier (KAEK — Κωδικός Αριθμός Εθνικού Κτηματολογίου). Properties enrolled in the Ktimatologio have their boundaries mapped on digital cadastral maps, which can be viewed via the Ktimatologio's public web portal (ktimatologio.gr).
For property buyers in Greece, the Ktimatologio search (or the Hypothikofilakio search in areas not yet enrolled) is a mandatory step in due diligence. The search confirms: who is registered as the legal owner; whether any mortgages, charges, seizures, or other encumbrances are registered on the property; and whether the registered boundaries match the property as physically presented. Your Greek property lawyer (or symvoliografos) will conduct these searches before the final purchase deed.
A significant issue in Greek property law is the large number of properties with incomplete, irregular, or disputed registration in the Ktimatologio. This is particularly common for properties inherited before the modern Ktimatologio was established, agricultural land in rural and island areas, and properties built or extended without planning permission (authaireta). The Ktimatologio registration process required all property owners to formally declare their properties during a registration period; owners who missed these deadlines or filed incomplete declarations may have disputed or unregistered entries.
Non-EU Golden Visa investors and other foreign buyers of Greek property are increasingly scrutinising Ktimatologio entries as part of legal due diligence. A clean Ktimatologio extract (Pistopoiitiko Ktimatologiou) showing the vendor as the registered owner with no encumbrances is a basic requirement before any purchase. If the property is not yet in the Ktimatologio (still in the Hypothikofilakio area), your lawyer should conduct searches at the relevant Hypothikofilakio instead and verify the chain of title going back at least 20 years.
The Ktimatologio is Greece's new national land register with cadastral mapping, being rolled out region by region. The Hypothikofilakio is the older mortgage registry system that records property deeds and charges without cadastral maps. Areas not yet transferred to the Ktimatologio still use the Hypothikofilakio. Your Greek lawyer will advise which applies to your specific property.
The KAEK (national cadastral code) can be found by searching the property's address on the Ktimatologio public portal (ktimatologio.gr), or on recent official property documents such as an E9 declaration or notarial deed. Your Greek lawyer will use the KAEK to pull the official Pistopoiitiko Ktimatologiou extract for due diligence purposes.
Yes — once a property is definitively enrolled in the Ktimatologio, the state guarantees the registered title. This is known as the constitutive effect (konstitutiko apotelesmato) of registration. However, during the transition period, some registrations are in "provisional" status and lack the full state guarantee. A Greek property lawyer can confirm whether the registration is provisional or definitive.
