In mediation, a neutral expert assists the parties to reach a voluntary resolution of the dispute. Even when parties are required to attend mediation, every agreement reached in mediation is voluntary. When and where to mediate, and who will mediate, are choices made by the parties. Whether or not lawyers attend the mediation and what role they fill at the mediation are also matters of choice. The outcomes that are reached by the parties are often detailed as well as creative and may, by consent, address other matters.
