Unlike in court cases, the arbitrator is chosen by the disputing parties. Oftentimes in contract clauses the mention of arbitration is included in the case of disagreement. Once the arbitrator is selected, the arbitrator reviews the issue and the evidence provided, whether this is done at a centre, remotely or through hybrid hearings that combine the two. They go over the evidence, listen to the disputing parties and then proceed to make a decision. There are numerous bodies that provide experienced arbitration services and more. While the larger ones are more expensive, the smaller firms are also effective in their proceedings and they still, generally,cost much less than taking the case to trial. Some work independent of any firm as freelancers. In the process, many parties often consult their own lawyers as well if large sums of money are involved, especially.
