What alternatives are available instead of filing suit?
The three most common alternatives to a formal trial are negotiation, mediation, and arbitration. Those favoring these techniques claim that the process is often faster, less traumatic, and less expensive than traditional litigation, and can produce a better or fairer result. Arbitration and Mediation are techniques that are discussed as subtopics of Litigation.
Because the results of a lawsuit are unpredictable (you may lose), and given the costs and difficulties of going to court, all lawyers first consider trying to settle the claim.
