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.
The declaration of co-ownership is the deed containing all the organizational rules of a co-ownership. This document also provides conditions of use and enjoyment of the common and private portions.
Life in a co-ownership surmises that changes will become compulsory on account of changing living habits, temperaments, the era and technological advances. Thus the declaration of co-ownership is evolutionary. It can be amended by the co-owners, provided they abide to the relevant formalities of the Law.
