Definition : Co-ownership by phases - Concomitant co-ownership

A co-ownership established within in the framework of setting-up a co-ownership by phase. The concomitant co-ownerships are erected on the private portions of  the initial co-ownership. Each of them is legally autonomous both for the management and maintenance of its building. This co-ownership type  may be vertical (residential tower) or horizontal (townhouse complex). These two layouts can coexist in the same initial co-ownership.

However, the appointment of directors generally falls within the competence of the general meeting of co‑owners, although the declaration of co-ownership may provide for other provisions.
