The person who occupies an apartment (a private portion) without being one of the co-owners of the immovable or a tenant. The spouse or the children of a co-owner are thus occupants.
The declaration of co-ownership is binding upon the co-owners and, in principle, on the occupants and tenants of the immovable. It is the responsibility of the Board of Directors to enforce its content. By failing to do so, the members of the Board may, in some cases, be held liable toward the co-owners.
