The declaration of co-ownership is a document that encompasses all the rules specific to a syndicate of co-owners, in order to ensure the proper functioning of an immovable and cohesion between its occupants. It also specifies the conditions of use and enjoyment of the common and private portions. Co-ownership living is not static. It is evolutionary and subject to change, which will sooner or later be claimed by co-owners. This evolution will sometimes lead to amendments to the declaration of co-ownership, subject to compliance with the terms and conditions set out in the Act. Thus, any amendment to the declaration of co-ownership is generally the subject of a vote at a meeting of co-owners. The vote to make such an amendment differs according to the nature of the change to be made.
