Using a method of ADR is less formal than using the courts - parties can solve issues themselves
Lawyers are not encouraged as:
process is flexible and less formal
there is no rule that the loser pays the winner's costs which means it is likely for the costs of parties to be lower and there will be no winner/loser situation
It is quicker and easier than going to courts. If there is a hearing, it is likely to be in private and there will be little or no publicity to embarrass the parties
In negotiation, conciliation and mediation the decision doesn't have to be strictly legal and is more likely to be based on commercial common sense and compromise.
