The destination of the immovable, of the private portions and of the common portions is a fundamental concept in co-ownerships. It is determined in the first part of the declaration of co-ownership (constituting act of co-ownership).The destination allows the determination the type of co-ownership established and defines the use(s) that can be made of the private and common portions. The destination of the immovable can be exclusively residential or commercial or residential but with the possibility of exercising professional activities. It can also be mixed, such as, allowing shops on the ground floor and apartments on the upper floors.
The declaration of co-ownership includes the set of rules ensuring the efficient organization of a co-ownership. Its knowledge by the members of the board of directors and by each co-owner is essential to the proper operation of the co-ownership. This co-owners reference document is consulted, for example, in the case of work. For a promisor-buyer, the declaration of co-ownership contains a wealth of useful information regarding the conditions of use and enjoyment of the private and common portions. Hence the necessity of reading this document before buying, to avoid unpleasant surprises, especially as to the use one intends to make of his private portion.
