Yes, it is a private and confidential process.  If a mediator is involved, the mediator(s) will not reveal what is said in the mediation except (as required by law) to report suspected child or elder abuse or threat of physical harm or damage to property.  The parties agree that the mediators will not be called to testify should future judicial proceedings occur in this case.  The parties agree not to contact the mediators outside the mediation process.
