Cadastral mediation in Greece: land registry corrections and preparation

When cadastral mediation is worth considering

A disagreement about ownership, a fractional share or how a property appears in the land registry needs a shared documentary basis. Family understanding that a field or house belongs to someone is not enough on its own. The entry, deeds and precise correction sought must be examined together.

The special procedure under Article 6 of Law 2664/1998 concerns specified proceedings to correct initial cadastral entries. It does not automatically apply to every application to the Hellenic Cadastre. An obvious error, a mapping discrepancy and competing ownership claims may require different approaches. Mediation is not a means of bypassing missing title evidence or third-party rights.

The initial session, impartiality and the 2026 changes

A cadastral mediator facilitates communication without representing either side or imposing a settlement. The parties’ lawyers assess their rights and the implications of proposals. Attending a mandatory initial session, where required, is different from consenting to a final agreement. If served with a claim or invitation, obtain timely advice rather than ignoring it.

Law 5326/2026 sets particular requirements for extraordinary adverse-possession claims concerning property recorded as ‘owner unknown’. The Central Mediation Committee clarified that the relevant sessions from 16 September 2026 require a cadastral mediator who holds a law degree. General mediator accreditation alone is therefore not a sufficient description of the qualification needed for these cases.

Law 5344/2026 has been published, but its provisions do not all commence together. Article 155(12) provides a cadastral transitional arrangement through 28 February 2027, while the revised wording of Article 6 introduced by Article 186 takes effect on 1 March 2027 under Article 217. The dates, type of dispute and transitional provisions must be checked before arranging a session.

Preparing the legal and technical file

Start with documents already available rather than ordering certificates indiscriminately. Record who is shown as the holder, who disputes the entry and exactly what change is requested. For property in Heraklion or elsewhere in Crete, identify the location and cadastral reference, known as the KAEK, rather than relying only on an informal place name.

Where boundaries, area or mapping changes are involved, coordination with an engineer matters. A proposed settlement must be technically workable and capable of examination for registration. The statutory cases may require specified diagrams and evidence of electronic submission; a handwritten sketch is not a substitute. The checklist below is a starting point, not the complete statutory evidence list for every dispute.

• Deeds and available certificates of transcription or registration
• Cadastral sheet, KAEK and relevant diagrams
• Claims, invitations, proof of service and earlier decisions
• Succession documents where the claimed right comes from an inheritance
• Technical material and evidence of possession relevant to the claim

From agreement to registration: steps not to overlook

Within the special statutory framework, an appropriate settlement record can be registered on the cadastral sheet to correct an inaccurate initial entry. That is different from an oral concession or an informal private note. Its content, signatures, necessary attachments and filing or registration steps need review. If a further transfer or other legal transaction is intended, its formal requirements must be assessed separately.

Correction deadlines for initial entries must be checked for the relevant area. Do not assume that informal discussions stop time running, or that every mediation step affects every deadline in the same way. Obtain advice on the specific time limit before deciding to wait. A short outline and critical dates are sufficient for first contact; agree how to share detailed documents afterwards. Sources checked on 22 October 2026.
