Distinguishing between the function of the Co-ownership manager (gérant) and the Condo manager (gestionnaire) is not an easy task. Most participants who work in the field of co-ownership are struggling with this issue. In fact, the general perception of the similarity of their incumbent duties is wrong, as there are several differences between these two functions. The Co-ownership manager has decision-making powers regarding the management of the co-ownership. On the other hand the Condo manager acts as an advisor and is the one who implements the decisions made by the board of directors. This does not preclude him from making recommendations before these decisions are implemented. A discussion on two similar but not identical functions whose attributes, powers and duties are to be distinguished in many ways.
