Condominium tenants: what is it?
Verified 11 May 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)
In a condominium building, each lot (apartment, cellar, parking, commercial space, etc.) includes a privative part and one co-payment of common areas. The tenths of co-ownership correspond to this share of ownership in the common areas. We present you the information to know.
The tenths correspond to the share of ownership of the common areas (stairs, roof, corridors, yard, etc.) assigned to each batch in a condominium building. They represent the share undivided (fraction of property held with others) belonging to each co-owner.
The tithes are described in the Descriptive Division Statement (DDS) in the condominium rules or as an annex to it.
They are generally expressed in thousandths or ten-thousandths.
Warning
Condominium tenths should not be confused with tenths of charges. The latter determine the share of each batch in the condominium expenses (general and special charges).
The tenths are used in particular to determine the number of votes available to each co-owner during the votes in general assembly.
Indeed, the number of votes of a co-owner corresponds to his share in the common areas. In other words, the more a co-owner owns a significant share of the common areas, the higher his number of votes is during the votes at the general meeting.
Similarly, when the syndicate of co-owners sells a common part, the price is divided between the co-owners in proportion to their share of the common parts. Thus, the tenants of co-ownership determine the share of each co-owner in the sale price of the common parts or the price of the acquisitions (purchase) made by the syndicate of co-owners.
In principle, tenths of co-ownership are calculated according to the following criteria:
- The area of the condominium lot
- Its consistency (nature, importance of the lot: apartment, business, cellar, parking, etc.)
- Its location (floor, view, sunshine, orientation, location in the building, etc.).
The parties may, however, choose another method of calculation for the tenants of co-ownership. For example, allocation may be based on market value lots at the time of co-ownership.
The tenants of the condominium are fixed at the time of the condominium and, in principle, can no longer be modified.
However, several exceptions are allowed.
The 1era exception concerns the modification of the tithes by a vote in the general meeting by the unanimous consent of the co-owners. Thus all co-owners must give their consent, without exception.
In practice, this modification of the tenths requires the following 4 conditions to be met:
- An enrollment in theagenda of the general assembly with a precise draft of a new distribution of the tenths (often drawn up by an expert surveyor or notary)
- A unanimous vote of the co-owners
- The drafting of an amending act of condominium rules and thedivision descriptive report
- The publication of these acts in the service of land advertising.
The 2nde exception concerns 3 situations that allow to modify the distribution of the tithes by a vote in the general meeting at the double majority Article 26. These are:
- Elevation of the building
- Division of the original syndicate of co-owners to form separate and separate co-properties
- Creation of new lots from common areas, for example when an old common area (lodge, corridor, common toilet, garden, etc.) is sold in order to be converted into a private area.
