The mediator will open the mediation either by meeting the parties (and their legal representation) in a plenary (joint) session or in private sessions if tensions are running high, giving each party the opportunity to talk about their perspective on the dispute. The mediator may then hold a further series of confidential meetings with each side to see how the dispute can be moved on. Any progress and agreement that is reached can be set out in a mediation heads of agreement for the parties to sign.
