Land mediation concerns the structured procedure for the correction of inaccurate initial cadastral records, but also more generally cases concerning issues of real property (usufruct, exclusive use agreement, distribution, etc.) and cadastral law. Article 8 of Law 4821/2021 stipulates that from 01/04/2022 there is an obligation to conduct a mandatory initial session (mandatory initial session) in cadastral cases. Specifically, the plaintiff must, prior to the discussion of the lawsuit and under penalty of inadmissibility of the discussion, invite all defendants to a mandatory initial session (YAS) of mediation. The mediation session shall be conducted before a cadastral mediator selected from a special register, which shall be established and maintained in electronic form by the Central Mediation Committee of Article 10 of Law No. 4640/2019. A mediator from the general register may not undertake the procedure. Specialisation and registration in the special register of land mediators is required. Very important is the fact that if an agreement is reached, the record of the cadastral mediator if it has been filed with the competent district court and has become enforceable is entered in the cadastral sheet and the inaccurate cadastral registration is corrected without any other procedure. In the event that geometric changes to the cadastral diagrams are requested with the claim, the topographic diagram of geometric changes and the proof of its electronic submission to the electronic database of the Entity shall be attached to the mediation record.
