Owners of illegally constructed buildings that have not yet been registered in Montenegro’s real-estate cadastre must initiate registration by 14 August 2026. The deadline was extended by six months after administrative and surveying capacity proved insufficient for the original timetable.
The August cutoff applies to cadastral registration, not completion of the entire legalisation procedure. Buildings already recorded as illegal are not subject to the same registration deadline, although their owners must still complete legalisation before obtaining full transaction certainty.
Failure to initiate registration can result in a removal order and prevent the building from being legally sold, mortgaged or used for commercial activity. This is particularly important on the coast, where historic extensions, converted residential units and tourism properties frequently differ from approved plans.
The framework is separating the property market into legally secure and administratively impaired assets. Clean-title buildings should command a liquidity premium because they can support conventional bank finance and notarial transfer, while properties caught outside the process may become effectively unbankable. Purchasers of apartments, hotels and development land will need to verify the status of every structure on a parcel rather than relying solely on ownership of the underlying land.
