While a small number of cases make it to trial, most personal injury claims are resolved through an insurance settlement, which is an agreement between the injured victim and the insurance company. The victim receives compensation for losses and damages while the insurance company is released from any future liability for the injury.
Many settlements are reached before a lawsuit is even filed. There are also a fair number of settlements that are agreed to after a lawsuit is filed. That is why injured victims should find an attorney with courtroom experience who is prepared to file a lawsuit. Sometimes filing a lawsuit is the extra push needed to convince an insurance company to increase its settlement offer.
Civil trials are costly and take a long time to complete. That is one of the main reasons why most personal injury cases do not make it inside of a courtroom.
