Ktimatologio: the Greek Cadastre (Land Registry) Explained for Buyers

The Ktimatologio is Greece’s national cadastre, the state register that records who owns each property, its boundaries and the rights and charges attached to it. For buyers it is the first place to check a title. This guide explains what the Ktimatologio is, how far it covers the country in October 2026, how owners abroad check their record, which certificates to order before signing and how errors are corrected.

At a glance

• The Hellenic Cadastre is a public-law body under the Ministry of Digital Governance, established by Law 4512/2018.
• Ministers said in September 2026 that 99% of the country is now covered, with the survey expected to finish in December.
• Where the Cadastre is in full operation, deeds are filed digitally, searches are online only and certificates are issued at any hour.
• Owners abroad can see their registered properties online with Greek TAXISnet credentials.
• Each property has a National Cadastre code (KAEK), now carried into the owner’s E9 property return after a sale filed through myPROPERTY.
• Wrong first registrations can be corrected within deadlines that differ by area.

What the Ktimatologio is

The Ktimatologio (Κτηματολόγιο) is a single, continuously updated register of property and property rights, kept under the responsibility and guarantee of the State. The body that runs it is the Hellenic Cadastre (Ελληνικό Κτηματολόγιο), a public-law legal entity supervised by the Ministry of Digital Governance. It was set up in its current form by Law 4512/2018, according to the Cadastre’s own description.

The Hellenic Cadastre records:

• every act that creates or changes a right in a property, recorded against the property itself;
• the shape, location, size and boundaries of each property;
• rights and charges that can be registered, such as mortgages;
• public property and rights acquired by long possession (χρησικτησία).

How it differs from the old land registry

Before the Cadastre, Greece’s land registry was a network of local mortgage and transfer offices (υποθηκοφυλακεία). The Cadastre records each act by reference to the property, and the Cadastre says legal information is checked for legality before it is entered. The old offices are being absorbed into the Cadastre’s own offices and branches.

At an event in September 2026, the Cadastre’s director general said 392 old registry offices had closed, so no procedure now requires physical presence. Foreign buyers will often see the Greek land registry and the Cadastre used as if they were one thing. In areas in full operation, they now are.

Coverage of the Hellenic Cadastre in 2026

The Cadastre now covers almost the whole country, but areas switch to full operation one by one. At the Cadastre’s Thessaloniki fair event on 5 September 2026, the minister said coverage had risen from 36% in 2019 to 99%. The director general gave 38% for 2019 and the same 99% today. The survey (κτηματογράφηση) was expected to finish in December.

What full operation means

The Cadastre lists the changes in each area that moves to full operation:

• notarial deeds are submitted digitally, except in special cases;
• corrections and requests to fix obvious errors are filed only digitally;
• searches of the cadastral database are online only;
• certificates and copies are available digitally at any hour;
• stamp duties on applications and certificates are abolished;
• payments are electronic only, by e-banking or card;
• on-site search hours are 08:30 to 13:30 across the country.

How owners abroad check their Ktimatologio record

Owners abroad can check their record online with Greek TAXISnet credentials, which require a Greek tax number. Our guide to getting an AFM from abroad covers that step.

1. See your properties. The Cadastre’s property data service shows the current legal status of properties where you are registered as owner or usufructuary. It runs 24 hours a day.
2. Find the plot on the map. The Cadastre’s digital cadastral map lets owners locate a property. The Cadastre says it also shows what steps, if any, are needed to correct its data.
3. Order certificates. Official copies are ordered through the certificate service described below.

If the property search shows nothing, the Cadastre gives two likely reasons. Your tax number may not be matched to a cadastral record, or a right you declared during the survey may have been rejected. In that case, contact the competent Cadastre office.

Owners who cannot log in themselves can act through a Greek lawyer, who uses the Cadastre’s professional e-services. This suits buyers who sign by power of attorney.

The certificates to ask for before buying

The online certificate service has two menus, depending on where the property is. Areas under the Cadastre use one set of documents. Areas still under the older transfers and mortgages system use another.

Before a purchase, the cadastral sheet and the certificate of entries show what the Cadastre has registered on the property. The diagram extract shows the boundaries as plotted. Compare all three with the seller’s title deed, the building permit and the engineer’s survey. Our guide to illegal building works covers the engineer’s side.

How to order them online

The Cadastre describes the process as follows:

1. Log in with TAXISnet credentials.
2. Choose the system that covers the property’s area: Cadastre, or transfers and mortgages.
3. Select “new certificate application” and the type of document.
4. Fill in the property details and submit.
5. For some certificates a fee form is issued at once. For others the local office reviews the request first and either rejects it or issues a fee form within 10 working days.
6. Pay the form within 7 days. If it is not paid in time, the application is treated as inadmissible.
7. After payment, the certificate appears as a PDF in your account. Bank confirmation can take up to two working days.

The page does not publish fee amounts, which appear on each fee form. Certificates exempt from fees cannot be ordered online at present and must be requested at the competent office.

After the purchase: the KAEK and your E9

The KAEK is the property’s National Cadastre code. Under AADE decision A.1201/2026, when the E9 property return is created automatically after a transfer filed through myPROPERTY, the KAEK field is filled from the transfer tax return. Our report on the automatic KAEK in the E9 explains the change.

Automatic does not mean checked. After completion, open the E9 in myAADE and compare the KAEK and square metres with the cadastral sheet. The E9 is the basis for the annual property tax, so an error there carries into your ENFIA bill.

When the Ktimatologio record is wrong

Errors can be fixed, but the route depends on the type of error. First registrations follow area deadlines, while boundary errors go through an online platform.

Inaccurate first registrations

First registrations are the entries carried into each area’s cadastral book once its survey is complete. Every later entry builds on them, so an error there carries forward. An inaccurate first registration can be corrected within the deadlines set by Article 5 of Law 5076/2023, the Cadastre says.

The deadlines vary by area. The Cadastre publishes them in a national table organised by prefecture and municipality, last updated on 19 October 2026. Ask your lawyer to check the deadline for the property’s area before you sign.

Boundary and area errors

Since 18 September 2026, corrections to boundaries and other geometric data run on the metavoles platform. The Cadastre lists it as the service for requests under Law 5142/2024. The owner logs in with TAXISnet and appoints an engineer, who registers the diagram of the change, and a court bailiff, who serves co-owners and neighbours. The process has five stages:

1. application with supporting documents;
2. notification of interested parties, where required;
3. opinions and objections within a set deadline;
4. examination of the case;
5. decision and notification.

Appeals go to a second-instance Cadastre body or, under certain conditions, to the Cadastral Judge. For now the platform covers only cases where all parties are private individuals or companies. Cases involving the Greek State, public bodies or properties with unknown owners are excluded.

Common mistakes

• Checking the deed but not the Cadastre. The deed shows what the seller bought. The Cadastre shows what is registered today, including later mortgages or seizures.
• Ignoring the diagram. A plot whose plotted boundaries differ from the survey may need a correction before it can be sold cleanly.
• Assuming a correction is quick. Boundary corrections involve notice to neighbours and a period for objections. Build that time into the preliminary contract.
• Not checking the E9 after completion. A copied KAEK can still carry a copied error.

Frequently asked questions

What is the Ktimatologio in Greece?

It is the national cadastre, run by the Hellenic Cadastre under the Ministry of Digital Governance. It records each property’s owners, rights, charges and boundaries.

Is the Greek land registry the same as the Cadastre?

They are merging. The old local mortgage and transfer offices are being absorbed into the Cadastre, and areas in full operation use only the Cadastre system.

How do I check my property on the Ktimatologio from abroad?

Log in to the Cadastre’s property data service with TAXISnet credentials. You need a Greek tax number first, or a Greek lawyer can search for you.

Can I order Cadastre certificates without a Greek tax number?

Not online. The service requires TAXISnet credentials, which are tied to a Greek tax number. A Greek lawyer can order them through the professional e-services.

What is the KAEK?

The property’s National Cadastre code. It appears on the cadastral sheet and is now carried automatically into the E9 after sales filed through myPROPERTY.

Can a wrong first registration still be fixed?

Yes, within the deadline set for that area under Law 5076/2023. The Cadastre publishes the deadlines by municipality.

Who handles a boundary correction?

The owner applies on the metavoles platform and appoints an engineer and a court bailiff. The Cadastre office examines the case and issues a decision.

Buyers should confirm how this applies to them with a Greek lawyer or accountant, and check boundaries with a licensed engineer before signing.
