There is no single reliable average because Illinois personal injury settlements are based on documented losses, injury severity, liability, insurance coverage, and long-term impact. Medical expenses, lost wages, future earning capacity, pain and suffering, and comparative fault all affect value. Marker Law evaluates these factors, gathers supporting evidence, and negotiates against insurers seeking to minimize payouts.
