What is out of court settlement?

An "out of court settlement" means that the parties to a dispute reach an agreement to settle that dispute, and they do it without a judge making any type of order about the terms of the settlement. Quite literally, the "settle" the dispute "out of court".

Most lawyers are always in favor of an "out of court settlement" because the cost of taking a claim (a dispute) to court is usually quite high. When a dispute can be settled without intervention of the courts, it is most often the best outcome. There are exceptions, of course, but your attorney will be able to guide you.
