Hi,

A very interesting topic. I agree with the benefit mentioned above for the out-of-court dispute resolution.
Why we are settle out of court
1.An independent, neutral third person (a “neutral”) listens to the facts from all sides and tries to focus on the core issues.
2.A law or court order might require the parties to use ADR.

I also attach a link below showing how effective is alternative dispute resolution.
