Who is at Fault? Comparative Negligence in Illinois Personal Injury Cases

Navigating through a personal injury case can be a daunting task, especially when dealing with the intricacies of comparative negligence law in Illinois. This comprehensive guide aims to simplify the complexities and provide a step-by-step walkthrough of the process.

Understanding Comparative Negligence

Comparative negligence is a legal principle that determines the extent of responsibility each party holds in an accident. Unlike contributory negligence, where the plaintiff could be barred from recovering damages if they were even slightly at fault, comparative negligence allows for a more equitable distribution of damages based on each party’s degree of fault.

Illinois follows a modified comparative negligence system. This means that a plaintiff can recover damages as long as they are less than 50% at fault. However, their compensation will be reduced by their percentage of fault. For instance, if you were 30% at fault in a car accident, your damages would be reduced by 30%.


Types of Personal Injury Cases

Comparative negligence comes into play in various types of personal injury cases, including but not limited to:

Proving Negligence in Court

Proving negligence in court requires evidence that the defendant owed a duty of care, breached that duty, and that the breach caused your injuries. This might include medical records, witness testimonies, or accident scene photos.

Filing a lawsuit involves drafting a complaint, serving it to the defendant, and engaging in discovery. The settlement process may involve negotiations with the defendant or their insurance company.
