A Guide for Foreign Property Buyers

Updated September 2026

Buying property in Greece does not end when the purchase deed is signed. The transfer must also be registered with the competent Cadastral Office or, where applicable, the relevant Land Registry. The registration places the acquired right in the official property record and allows the buyer to confirm how that right, the property and its boundaries have been recorded.

For foreign buyers, the Hellenic Cadastre can be difficult to navigate because different online services apply at different stages of cadastral surveying. This guide explains what the Cadastre records, how to find a property, what to check and what to do when the information appears incomplete or incorrect.

What the Hellenic Cadastre Records

The Hellenic Cadastre, commonly called Ktimatologio, is Greece's official property information system. It brings together legal information about registered rights with spatial and technical information identifying each property. Unlike a register organised mainly around the names of owners, the Cadastre is property-centred: each cadastral property is connected with the rights and other registrations recorded against it.

Depending on the record and service used, cadastral information may include:

• The registered owner or holder of another property right.

• The type of right, such as full ownership, bare ownership or usufruct.

• The percentage or share of the registered right.

• The property's position, boundaries, shape and recorded surface area.

• The property's unique cadastral identification number.

• Registered mortgages, seizures, claims or other entries affecting the property.

A basic online view may not display every document or legal detail needed for a purchase. A lawyer conducting due diligence may need to obtain and examine the relevant cadastral sheet, diagram, certificates and registered deeds.

What a KAEK Number Means

Each cadastral property is assigned a KAEK, the Greek abbreviation for the National Cadastre Code Number. It is the property's unique identifier within the cadastral system. The KAEK helps professionals locate the correct cadastral sheet and map entry, but it is not the same as a street address, tax identification number or deed number.

A buyer should confirm that the KAEK shown in the transfer deed corresponds to the intended property and that the associated cadastral information is consistent with the title and technical documents. Apartments or other divided properties may have identifiers that distinguish the individual unit from the wider land parcel.

Why the Cadastre Matters in a Property Purchase

The cadastral record is central to both due diligence and completion. Before signing, the buyer's lawyer should investigate the seller's title and the registrations affecting the property. This can reveal ownership gaps, claims, mortgages, seizures or inconsistencies that require attention before the transaction proceeds.

After the notarial transfer deed is executed, it must be submitted for registration with the competent Cadastral Office or Land Registry. Articles 1192 and 1198 of the Greek Civil Code establish the importance of registering acts that transfer rights in immovable property. In general, where registration is required, the transfer of ownership does not take effect without it.

For the wider transaction sequence, including property selection, legal review, signing and completion, see Grekodom's step-by-step guide to buying property in Greece.

Common Cadastral Problems

Issues frequently identified during a purchase or ownership review include:

• An incorrect or incomplete owner name.

• The wrong type of right or ownership percentage.

• A missing deed or unregistered transfer.

• Incorrect boundaries, shape, position or surface area.

• A property recorded as unknown owner.

• Overlap with a neighbouring cadastral parcel.

• A mismatch between the cadastral diagram, title deed and current survey.

The appropriate correction depends on the nature of the problem and the stage of the cadastral record. Owners should not select a procedure solely because its online title appears similar to their issue.

How Cadastral Corrections Work

Corrections During Cadastral Surveying

While an area is being surveyed, owners can review published information during pre-posting or posting. Depending on the error, they may submit a correction or obvious-error application through the relevant service. Deadlines, evidence requirements and fees vary.

The official Posting and correction service explains the options available at the posting stage.

Corrections in an Operating Cadastre

Once the Cadastre operates in an area, Law 2664/1998 provides different procedures for obvious errors, inaccurate initial entries, geometric information and disputed rights. Depending on the issue, correction may require an administrative application, consent, notification, appeal or court decision.

Article 6 addresses inaccurate initial entries, while Articles 18 and 19 cover mechanisms including obvious errors and geometric corrections. Deadlines can be critical, particularly for initial entries or properties recorded as “unknown owner.” A lawyer should confirm the correct procedure and deadline.

Online Corrections of Boundaries and Geometric Information

From 18 September 2026, a new digital procedure is scheduled to apply to certain errors involving boundaries, surface area, shape or position. Established by Articles 7–10 of Law 5142/2024 and Hellenic Cadastre Board Decision 440/9/2026, it replaces specified procedures under Articles 18 and 19 of Law 2664/1998 within its scope.

A person with a legitimate interest—or an authorised representative—can apply through the metavoles platform using TAXISnet authentication. Where the cadastral map must change, an authorised engineer may submit a Diagram of Geometric Changes and obtain its electronic code. The platform checks the submission, but the Cadastre examines the application and issues the decision.

Affected neighbours or right holders must be notified and may object. Appeals may also be available. During the initial implementation period, some notifications may still require service through a court bailiff until automated notification becomes operational.

See Hellenic Cadastre Decision 440/9/2026 and the related Greek City Times report. Before filing, users should confirm that the platform is operational and review the latest official instructions.

Who Should Help With a Cadastral Issue

Where E9 and ENFIA Fit

E9 and ENFIA may describe the same property, but they belong to Greece's tax system rather than the Hellenic Cadastre. E9 is the owner's declaration of real-estate information to the tax authority. ENFIA is the annual property tax assessment calculated from the tax information, including E9 data.

Neither an E9 entry nor payment of ENFIA proves that ownership, title or boundaries are correctly registered in the Cadastre. Tax records can nevertheless help identify a discrepancy. If the area, ownership percentage or type of right shown in E9 differs from the cadastral and title information, the reason should be investigated.

Property owners can review tax-side information through the official AADE E9 and ENFIA service. An accountant or tax adviser should handle tax corrections. MBG Consulting Services provides financial, accounting and tax support and works alongside Grekodom in assisting international property clients.

Frequently Asked Questions

Should I use taxisnet gr, AADE or the Cadastre website to find my property

Use an official Gov gr or Hellenic Cadastre service to inspect cadastral information. TAXISnet credentials are used to authenticate you. AADE is used for tax records such as E9 and ENFIA, not as a substitute for the Cadastre.

Does paying ENFIA prove that I own the property

No. ENFIA is a tax assessment based on tax data. Ownership and other property rights must be established through the title documents and the applicable Land Registry or cadastral record.

Is the KAEK the same as the deed number

No. The KAEK identifies the cadastral property. A deed has its own notarial and registration details. Both should refer to the correct property, but they serve different purposes.

What should I do if my property does not appear online

First check whether the area is still being surveyed and whether you are using the correct service. Then ask a lawyer to examine the title and cadastral status. The absence may result from the stage of the area, an identification mismatch, an unregistered deed or an inaccurate entry.

Can I correct the boundary myself

A digital application may be available, but a boundary correction usually requires technical evidence and may affect neighbouring properties. An engineer or surveyor should assess the geometry, and a lawyer should advise where rights, objections or appeals are involved.

Can a foreign owner complete the process remotely

Many checks and submissions are digital. Where representation is permitted, a properly authorised lawyer, engineer or other representative may assist. The required authority and documents depend on the procedure.

What if the surface area differs between the deed, Cadastre and E9

Do not assume that one figure automatically overrides the others. A lawyer, engineer and accountant may need to establish whether the difference arises from measurement, description, legal status or a tax-record error and then correct the appropriate record.

Final Checklist for Foreign Buyers

• Confirm the status of cadastral surveying in the property's area.

• Use the correct official service and authenticate through TAXISnet when required.

• Ask a lawyer to check the title, cadastral sheet and registered burdens before purchase.

• Confirm the KAEK, ownership right and property description in the transfer deed.

• Ensure that the executed deed is registered with the competent office.

• Obtain proof of registration and verify the resulting cadastral entry.

• Investigate discrepancies before a future sale, mortgage, gift or inheritance makes them urgent.
