Illinois deadlines for filing an injury lawsuit vary by claim type and the parties involved. Missing an applicable deadline can prevent recovery, and facts such as a government defendant, a workers’ compensation claim, or a wrongful death matter may affect the analysis. Preserve evidence and seek legal guidance promptly so the relevant deadline and claim requirements can be evaluated.
