Conflicts within co-ownerships are not uncommon. They can arise between co-owners, in particular in the context of neighborhood annoyances (noise, abusive uses of the common portions) but also between the board of directors and the co-owners. They can be resolved amicably, for example through mediation, or through the judicial process or arbitration. The Code of Civil Procedure encourages alternative methods of dispute resolution, such as mediation, arbitration or conciliation. It even obliges the parties to "consider" the use of private methods of prevention and settlement of their dispute before judicializing their dispute. These methods of settlement are in principle more user-friendly, accessible and expeditious.
In principle, co-owners have the right to enjoy their private portion as he sees fit. In addition, the law provides for a duty of tolerance on the part of neighbours, i.e. to accept the normal inconveniences that may result from the exercise of the right of ownership by the other. However, there are limitations to this use. In the event that the nuisance caused by an occupant of the building becomes excessive, it constitutes an abnormal neighborhood disturbance. It is common for such a case to constitute a breach of clauses relating to the peaceful enjoyment of the private portions, which are provided for in the by-laws of the immovable. That said, an abnormal neighbourhood disturbance does not systematically constitute a violation of the declaration of co-ownership. It should be noted that in certain circumstances, this type of inconvenience may be punished, even if the perpetrator has not committed any fault.
