Whether you are a real estate developer (for a new building) or several owners of an existing building who wish to convert it, the rules for subjecting a building to divided co-ownership are the same. The creation of a divided co-ownership is necessary when an immovable must be divided into lots composed of a private portion and a share  of the common portions, and which belong to one or more different persons. The community of co-owners acquires the status of legal person from the day a declaration of co-ownership is published at the Land registry office (Land Register). The legal person thus constituted takes the name of “syndicate of co-owners”. Its mission is to ensure the " preservation of the immovable, the maintenance and administration of the common portions, the protection of the rights appurtenant to the immovable or the co-ownership, as well as all business in the common interest ". 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.
