Courts and Tribunals exist to make decisions on disputes, but using them is expensive, time-consuming and stressful.
For many years now it has been expected that parties using Courts and Tribunals do so as a last, not a first, resort.
This is backed up, particularly in the civil courts, by the power of the courts to penalise those who do not make a reasonable attempt to resolve disputes before resorting to litigation.
Traditionally negotiation, either in writing or by telephone or in meetings, has been the way of trying to reach a compromise, or at least reduce the areas which are in dispute. That remains the case.
There are, however, now other options available, such as mediation (a form of negotiation facilitated by a third party) or arbitration (which can be binding or non-binding).
