Divided co-ownership, also known as condominium, is a form of ownership. In a divided co-ownership, the co-owner owns a housing unit (condo unit) on which he exercises the usual rights of a homeowner. He can arrange, decorate and carry out minor renovations in his housing unit as could do the owner of a single family home and this, without having to obtain permission from the other co-owners. It is then called the private portion. The building in which is located the housing unit does not belong exclusively to the co-owner of the housing unit. This is what constitutes the common portion of the building. The building belongs to all the co-owners in proportions that can vary from two to several tens.
The common portion is then the joint and concurrent responsibility of all the co-owners who, as a body, constitute a legal person called the syndicate of co-owners. It is the syndicate of co-owners that will allow the work to be performed on the building structure or on the other private units. Divided co-ownership is therefore a right of ownership that is not absolute, but that must be exercised jointly with the other co-owners.
