At the time of acquiring an immovable property held in undivided co-ownership, it is very useful to proceed to the evaluation and inspection of the immovable property. In fact, the undivided co-owners do not purchase only a fraction of the immovable property; they become owners of the whole building with a right of use of certain portions as explained previously. It is therefore recommended to proceed to such an expertise in order to protect an investment of several thousands of dollars.
