What is the meaning of “cadastre vertical”:

The “cadastre vertical” is the division of a building into separate private lots (apartments, garages, cellars, etc.) following the law of 16 May 1975 on the status of co-ownership of buildings. It thus provides a unique and unambiguous definition of each private lot called a cadastral designation and is intended to be included in notarial deeds documenting transfers of ownership.

Each separate private part constitutes a private lot with a share of the common parts expressed in thousandths. Each private lot is assigned a number or a cadastral designation that allows it to be identified in relation to the entire building.

Who is affected:

The “cadastre vertical” applies to all buildings built or to be built comprising several residential units, offices, shops…

The establishment of a “cadastre vertical” is mandatory for any building, newly built or already existing, subject to the co-ownership status since 1989. Buildings organized in co-ownership before 1989 must be regularized until 2024. (excerpt from the site of the administration of the cadastre and topography; see the law of 19 March 1988 on land registration in matters of co-ownership)

Composition of a dossier:

The elements to be provided for a dossier vary from one building to another, depending if it is old, or if there is one or multiple owners.

In general, a dossier includes a descriptive table of division, spreadsheets detailing the elements (levels, surfaces, coefficients, quotas) and related plans (floor plan views, section(s) and location plan). An application form containing the building data (address, cadastral numbers) and annexes such as a copy of the construction permission are also part of the dossier to be submitted. A certificate proving the number of units approved by the municipality or an official document attesting to the address of the building is sometimes requested.

For older buildings that already have a co-ownership by-law, copies of the property titles, basic deeds or co-ownership by-laws must also be added and this information must also be included in the description table of the private lots.
