Legal documentation

The declaration of co-ownership is intertwined with the purchase of an apartment held in divided co-ownership. A genuine "user's guide", this document defines the rules to be observed in the immovable, as well as its administrative and management guidelines. Before acquiring a condo, any careful buyer should, imperatively, read the declaration of co-ownership. He will thus be able to verify the extent of his obligations and duties and the limits to his ownership rights. He will be able to evaluate its terms and conditions and make a decision on buying or not.

Content of the declaration of co-ownership

The instruction manual of a syndicate of co-owners, the declaration of co-ownership is divided into three parts: The Constituting act of the co-ownership, the Description of the fractions and the By-laws of the immovable. It lays down all the rules ensuring the proper functioning of the co-ownership and the management of the community of co-owners, lessees and occupants of the immovable. From a legal standpoint, its role is, without limitation to:

What you should know

The declaration of co-ownership contains information on the immovable and the use of the private portions. It includes (inter alia) a section that addresses the destination of the immovable, the living conditions that have been implemented, and the means used to ensure compliance and management thereof. Its content is voluminous, but enlightening. The prospective buyer will learn what is allowed or not in the co-ownership. For example:

  • Is it allowed to have an animal?
  • Can a co-owner install hard flooring (e.g. hardwood floors and ceramic tiles) in his apartment?
  • Is the practice of a profession allowed in a unit?
  • Are short term rentals (such as Airbnb) prohibited?
  • Do the by-laws of the immovable prohibit the rental of units for a term of less than one year?
  • Does the co-owner-lessor have obligations with respect to leasing his unit, such as providing proof that the by-laws of the immovable's have been remitted to his lessee?
  • Does a co-owner-lessor have the obligation to give a copy of the lease to the syndicate?
  • How is the right to use outdoor parking spaces determined?
  • How is the allocation of common expenses calculated?

Amendments to the declaration of co-ownership

The declaration of co-ownership may have been modified over time. It is therefore necessary to obtain a copy and pay attention to the amendments to the declaration of co-ownership  since the establishment of the co-ownership. Such verification is all the more difficult regarding the amendments to the by-laws of the immovable, since they are neither notarized nor published in the Quebec Land Registry. Although these changes are filed in the register of the co-ownership, and they are private information, a prospective buyer can nevertheless consult them on request.
