Since 2011, it is strictly prohibited to perform notarial transfers for properties containing unauthorized structures unless a legal settlement process has been initiated. A certified topographic diagram in HGRS87 is required as part of the submission under the provisions of Law N.4178/2013.

mtopo.gr, with deep knowledge of urban planning legislation, prepares detailed topographic surveys and certifies the exact spatial extent of unauthorized buildings and land use. These diagrams are essential for issuing the relevant compliance declarations and for inclusion in legal files concerning property regularization.
