In Illinois workers’ compensation cases, attorney fees are typically around 20% of the recovery, and Marker Law handles these claims on a contingency fee basis. That means there are no upfront legal fees, and clients pay attorney fees only if the case results in financial recovery. The initial consultation is free, so injured workers can understand their options before deciding.
