The declaration of co-ownership is a contract that orchestrates and regulates the lives of co-owners, lessees and other occupants of the immovable. It represents the guideline for everyone who lives in the immovable. The declaration of co-ownership provides, systematically, that it is up to the board of directors to have its content abided to. However, it happens that people break the rules, in particular by a non-compliant use of a private portion with regard to the destination of the immovable, a noise nuisance and work carried out in violation of the by-laws of the immovable. Other examples illustrate the problems that can occur in the co-ownership, such as an encroachment on a common portion or the improper installation of a floor covering. Anyone who does not abide to the declaration of co-ownership is liable, inter alia, to a legal recourse based on article 1080 of the Civil Code of Québec. This action may be brought by a co-owner or the syndicate.
