From the first day of existence of the co-ownership, that is to say when its declaration of co-ownership is published in the Land Register of Quebec, the co-owners as one body constitute a “syndicate of co-owners”. This legal person must ensure the "preservation of the immovable and manage the common portions." To form this co-ownership several steps involving many protagonists are necessary.
The characteristic of divided co-ownership is to divide the building into various lots that will be the exclusive property of the co-owners (private portions), and for others that will be the property of all the co-owners (common portions). These lots are identified by an individual number, which was assigned during the cadastral operation. Each of the private lots of the co-ownership thus constituted becomes a unique property. The distinction between the common and private portions is essential, particularly from the point of view of maintenance, which is the responsibility of the syndicate of co-owners for the common portions and of the co-owners for the private portions.
