How fault affects your claim in Illinois

Illinois bars recovery if you are found more than 50% at fault. If you are 50% or less at fault, your damages are reduced by your percentage. Because the 50% line decides everything, evidence about who caused the crash matters greatly.

Claims against government in Illinois

Suits against Illinois local governments and their employees are governed by the Tort Immunity Act, which sets shorter deadlines than the usual two years. These deadlines are strict, so contact an Illinois attorney as soon as possible if a public body may be involved.
