The value of a personal injury claim depends on factors such as injury severity, medical expenses, lost wages, future earning capacity, pain and suffering, and liability. Illinois’ modified comparative negligence rule can also affect recovery. Marker Law evaluates the available evidence, damages, and insurance issues before negotiating for fair compensation rather than relying on a generic settlement estimate.
