The conversion of a immovable to divided co-ownership (condos) is subject to strict formalities and municipal by-laws, which can restrict the conversion or make it subject to certain conditions.. Unfortunately this does not always prove possible, more particularly because of the very high costs such a process implies (such as subdivision taxes known «Parkland taxes» applicable in certain boroughs of Montreal or other municipalities) and vested rights in favor of tenants.
From the first day of existence of the co-ownership, that is to say when its declaration of co-ownership is published in the Land Register of Quebec, the co-owners as one body constitute a “syndicate of co-owners”. This legal person must ensure the "preservation of the immovable and manage the common portions." To form this co-ownership several steps involving many protagonists are necessary.
