One of the most common problems encountered by property owners following the completion of cadastral surveying is the existence of errors in the cadastral folio: an incorrectly recorded owner’s name, an inaccurate co-ownership percentage, incorrect title details or even the designation “unknown owner” for a property whose owner can be identified. The appropriate correction of a cadastral entry in Greece depends on the type of registration, the nature of the error, the available evidence and the stage reached by the cadastral survey.
Why Errors Occur in Cadastral Entries
Cadastral surveying is a complex process involving the collection and legal and technical examination of millions of property rights throughout Greece. It relies on property declarations, deeds, registration certificates, administrative acts and topographical data.
Errors may occur during the processing of this material, ranging from simple inaccuracies in the owner’s personal details to incorrect ownership percentages, omitted title deeds, inaccurate descriptions of the registered right or incorrect geometric data.
What Is a Manifest Error?
Under Article 18 of Law 2664/1998, a manifest cadastral error, also commonly described as an obvious error, may be corrected where the inaccuracy is established beyond doubt from the documents and data specified by law, without requiring the resolution of a genuine ownership dispute.
An error does not qualify as manifest merely because the applicant believes that it can easily be proven. The specific statutory conditions must be satisfied, and the requested correction must not conceal an informal transfer of ownership or an unauthorised alteration of title.
Typical examples include:
- Incorrect personal details of the registered owner, such as their name or patronymic, where the correct details are established by an identity document or another public document.
- An error concerning the registered right or the details of the acquisition title.
- An incorrect co-ownership percentage where the correct percentage is established beyond doubt by the registered deed.
- An unjustified discrepancy between the initial registration and the information contained in the public display or the final revised cadastral table.
- An incomplete or inaccurate registration of a horizontal or vertical property where the correction follows from the deed of establishment, the applicable regulations and the relevant public documents.
- An “unknown owner” cadastral entry where the right is evidenced by a public instrument registered with the former Land Registry before the public display and the remaining statutory conditions are satisfied.
How a Manifest Error Is Corrected
The procedure begins administratively before the competent Cadastral Office or Branch:
- The Head of the Cadastral Office may correct the error following an application by a person with a legitimate interest or on the Office’s own initiative.
- The application must identify the property and its KAEK cadastral number, describe the error precisely and specify the correction requested.
- It must be accompanied by the documents establishing the correct information, such as deeds, registration certificates, deeds establishing divided ownership, administrative acts or other public documents.
- The application is entered in the cadastral folio of the property.
Where the Cadastral Office or Branch already holds the necessary documents in its records, the law provides for their retrieval by the Office. Simple copies submitted by the applicant may also be taken into account.
For the specifically regulated categories of manifest errors affecting initial registrations, the Head of the Cadastral Office must either make the correction or issue a reasoned refusal within 30 working days. Where a prior response from the Greek State is required, this period is suspended for the corresponding length of time.
In the event of rejection or failure to examine the application within the statutory period, Article 18 provides, subject to its specific conditions, for an application to the Cadastral Judge within 30 working days.
An application for the correction of a manifest error is not a compulsory preliminary step before court proceedings. Its submission should not be treated as suspending or interrupting the exclusive statutory time limit for bringing an action to correct an inaccurate initial registration.
Properties Registered as “Unknown Owner”
The designation “unknown owner” does not invariably require court proceedings. The correct procedure depends on the acquisition title, the date on which it was registered, whether a third party’s right is affected, the type of property and whether adverse possession is relied upon.
Where a public instrument was registered with the former Land Registry before the public display and no third party is displaced, the registration may be corrected as a manifest error if the requirements of Article 18 are satisfied. Where service of the application on the Greek State is required, it must take place within 10 days after filing. If the State does not issue a negative response within 60 days, it is presumed to consent. The law also identifies specific cases in which service on the State is not required.
Where the requirements for a manifest-error correction are not satisfied, the appropriate remedy may be an application to the Cadastral Judge under the non-contentious procedure or an action for the correction of an inaccurate initial registration. In particular, where extraordinary adverse possession is relied upon in respect of a land parcel registered as “unknown owner”, an action against the Greek State is generally required. A special rule applies to horizontal and vertical properties, for which an application may be brought even where extraordinary adverse possession is invoked.
Since April 2026, special provisions have also applied to the non-assertion of property rights by the Greek State and the recognition of third-party rights, where the conditions of Articles 12–14 of Law 5293/2026 are satisfied. Depending on the procedural stage, these provisions may permit correction without requiring the completion of contested court proceedings against the State.
When a Manifest-Error Application Is Not Sufficient
The manifest-error procedure is not appropriate where the case requires a substantive examination of competing titles, an evidential investigation of possession or adverse possession, or the resolution of an actual ownership dispute.
It is also unavailable where an incompatible subsequent registration has been made, unless the holder of the right arising from that registration consents and the consent does not conceal an informal transfer or alteration of title.
Where the error concerns the location, boundaries or surface area of a land parcel, the special geometric correction procedure under Article 19(2) of Law 2664/1998 applies. This generally requires a cadastral diagram and an appropriate topographical survey or geometric-changes diagram. Where neighbouring owners’ rights may be affected, they must be notified and given an opportunity to submit their written observations.
Where an actual dispute exists over a right inaccurately reflected in an initial registration, correction is sought by bringing an action before the competent Court of First Instance under Article 6(2) of Law 2664/1998.
The action must be brought within an exclusive period ending on 31 December of the year in which eight years have elapsed from the commencement of the statutory period. The period begins upon publication in the Government Gazette of the decision of the Board of the Hellenic Cadastre ordering the commencement of the Cadastral system’s operation in the relevant area.
The nature of the acquisition title, including adverse possession, may affect the procedure that must be followed. It does not, however, convert the applicable time limit into a general five-year period or justify delaying the examination of the registration.
Corrections During the Cadastral Survey
Before the initial registrations are created and the Cadastral system begins operating, interested parties may review and seek the correction of the provisional cadastral data.
During the Pre-Public Display stage (Proanartisi), right holders have access to the provisional data for 45 days and may submit a request for re-examination within the same period.
During the Public Display stage (Anartisi), an interested party may submit:
- A manifest-error correction application for evident inaccuracies.
- A correction application concerning more substantive legal or geometric issues.
Under the general statutory framework, a correction application must be filed within two months. A four-month period applies to residents abroad and the Greek State, and an extension of up to a further two months may be granted. However, cadastral surveying proceeds on an area-by-area basis and special or transitional arrangements apply to certain areas. The specific deadline officially announced for the area in which the property is located must therefore always be checked.
Following examination of the correction applications, the relevant reports are published. Where an application concerns the displacement of another person’s ownership or usufruct right, or the correction of geometric data beyond the accepted tolerance, the applicant must complete the required electronic steps and notify every affected owner within the applicable exclusive 30-day period.
An affected owner may, within the relevant 30-day period, consent to the correction or submit reasoned opposing observations. If the period expires without action, the owner is deemed to consent to the correction in accordance with the published report. Where opposing observations are submitted and the complete procedure under Article 6A of Law 2308/1995 applies, the matter is referred to an Examination Committee for Cadastral Survey Cases under Article 7A.
The word “objection” is still frequently used in practice as a general description of a challenge to cadastral survey data. Under the modern public-display procedure, however, a distinction must be made between a correction application, a manifest-error correction application and opposing observations filed following publication of the relevant report.
Practical Considerations
- Review both the legal information and the cadastral diagram during the Pre-Public Display and Public Display stages.
- Determine whether the matter involves a manifest, geometric or substantive ownership error, as each category follows a different procedure.
- Collect the title deed, registration certificate, deed establishing divided ownership and the necessary topographical documents before filing the application.
- Calculate the exclusive statutory period under Article 6 separately and do not assume that a pending administrative application suspends or interrupts the time limit for court proceedings.
- Boundary, surface-area and geometric-change issues require coordinated legal and technical examination.
Frequently Asked Questions (FAQ)
What is a manifest cadastral error?
It is an inaccuracy that may be corrected under the specific requirements of Article 18 of Law 2664/1998 without resolving an actual ownership dispute or making a substantive determination between competing property rights.
Who may request the correction?
Any person with a legitimate interest may file an application with the competent Cadastral Office or Branch. The Head of the Office may also make the correction on the Office’s own initiative.
Is a lawyer required?
Legal representation is not a general formal requirement for filing a straightforward administrative manifest-error application. However, particular care is required in selecting the correct procedure and establishing the legal basis of the request. Court applications and actions are governed by the applicable procedural rules. Geometric matters will also generally require technical work by a qualified engineer.
What happens if the error is not manifest?
Depending on its nature, the case may require a geometric correction application, a non-contentious application before the Cadastral Judge or an action for correction of an inaccurate initial registration. Court proceedings are not the only available remedy in every case.
What is the deadline for bringing a court action?
The exclusive time limit expires on 31 December of the year in which eight years have elapsed from publication of the decision ordering the commencement of the Cadastral system’s operation in the relevant area.
When is a correction application filed during cadastral surveying?
It is filed during the Public Display stage and by the deadline officially announced for each area. Under the general statutory framework, the period is two months and four months for residents abroad and the Greek State, subject to a possible extension. During the Pre-Public Display stage, a request for re-examination must be submitted within 45 days.
What is the difference between an objection and a manifest-error application?
A manifest-error application concerns an inaccuracy that can be corrected without substantively resolving an ownership dispute. Although “objection” is often used as a general term, the current Public Display procedure distinguishes between a correction application, a manifest-error application and opposing observations submitted after publication of the relevant report.
What is the risk of delay?
The opportunity to correct the matter during the more flexible cadastral-survey stage may be lost, making an administrative or judicial procedure necessary. If the exclusive period for challenging an initial registration expires, that registration may become final and generate an irrebuttable presumption, substantially restricting the remedies available to the true right holder.
