It’s not enough to believe someone else is at fault for your injuries. You have to prove it. The only way to win a personal injury case is to have enough Chicago personal injury evidence that an insurer is willing to settle, or a jury can award you compensation. It’s up to you to find the Chicago personal injury evidence that supports your personal injury claim. Then, you have to arrange and use it in such a way that persuades an insurer or jury that you’re right. Doing all of this is a tall order, especially if you’re unfamiliar with Illinois personal injury law and litigation.
We recommend you work with an experienced Chicago personal injury attorney who will gather evidence on your behalf, evaluate the strongest argument for your case, and fight hard for you to recover compensation.

When you file a personal injury lawsuit in Illinois, you become the plaintiff—the party responsible for proving that someone else’s negligence caused your injuries. Because you’re the one making the claim, the law requires you to prove the defendant is at fault. Even in civil cases, courts start with the presumption that the defendant is not liable. To recover compensation, you must overcome that presumption by presenting evidence that shows the defendant acted negligently.
In some limited situations, the burden of proof can temporarily shift to the defendant. This often happens if you can show that the defendant violated a law—such as a state statute or city ordinance—designed to protect public safety. If you prove this violation occurred, it serves as prima facie evidence of negligence, meaning the court will presume the defendant was negligent unless they can prove otherwise.
This creates a rebuttable presumption, shifting the obligation to the defendant to show their actions were reasonable despite the violation. However, this shift only applies to that specific presumption—it does not transfer the overall burden of proof in the case. You are still responsible for proving the remaining elements of your claim.
To win your case, it’s not enough to simply present evidence—you need to meet a specific legal standard. In personal injury cases, that standard is called a preponderance of the evidence. This means you must show it is more likely than not that the defendant’s actions caused your injury.
This is a lower threshold than the “beyond a reasonable doubt” standard used in criminal cases, but it still requires a clear and convincing presentation of the facts.
Not everything you collect makes it into court. The Illinois Rules of Evidence control what a judge or jury can consider. Evidence must be relevant, and even relevant proof can be excluded if it risks unfair prejudice, confuses issues, wastes time, or is inadmissible hearsay. Your attorney curates an “admissible core” of proof tailored to your case and anticipates objections so key facts are not excluded at the worst moment.
There are broad types of evidence, including direct and circumstantial evidence. Direct evidence speaks for itself. The evidence proves that a specific fact is true or false. Common types of direct evidence are confessions, eyewitness accounts of accidents, photos, and video footage.
Circumstantial evidence implies something. It asks the jury to infer that something is true. You might think circumstantial evidence is weaker than direct evidence, but this isn’t necessarily true. Entire cases have been won based on circumstantial evidence. In personal injury cases, this is known as res ipsa loquitur, which means implied negligence.
For example, if you were hurt in a car crash because another motorist ran a red light, there might be direct and circumstantial evidence to support a claim against the other driver. Your testimony and other eyewitnesses’ testimony are direct evidence. If the crash was caught on a traffic camera, the footage is direct evidence. But what if no one else saw the accident and there’s no video? You might rely on circumstantial evidence, like photos that show the angle at which your vehicle was struck and where your car ended up.

Seek medical care first, then contact a lawyer to issue spoliation (evidence-preservation) letters and secure time-sensitive proof—intersection videos, business surveillance, dashcam/EDR data, and 911 audio. Quick action can mean the difference between clear liability and a “he-said/she-said.”
You can win with circumstantial evidence if it logically supports negligence and causation. Skid marks, impact angles, vehicle telemetry, and consistent medical timelines often persuade adjusters and jurors even without a perfect video.
Police reports can be useful, but are not conclusive. We counter errors with photos/video, EDR data, independent witnesses, and expert reconstruction. Jurors care more about credible, consistent evidence than a single document.
They establish timing and mechanism: symptoms that begin soon after the crash, imaging that matches impact forces, and consistent treatment plans. Provider notes and specialist opinions help connect trauma to diagnosis and rule out unrelated causes.
It can. Insurers monitor public posts. Avoid discussing the crash or posting things that could be misconstrued. We recommend tightening privacy settings and pausing posting until your case resolves.
Policies vary—some overwrite in days. That’s why we move fast to identify cameras and demand preservation. Even if original video is gone, neighboring businesses or city-facing cameras may still hold useful angles.
Often, yes, for disputed liability or complex injuries. Reconstructionists, biomechanical experts, physicians, and economists translate facts into clear, credible explanations for causation, future care, and financial losses.
We use prior records, baseline function, and provider testimony to show that the crash aggravated or caused the condition. Illinois law allows recovery for aggravation of preexisting injuries with proper medical support.
There’s no magic number. “Enough” means a coherent, well-documented story where each element—duty, breach, causation, damages—is supported by reliable, admissible proof that makes your version more likely true than not.
Yes—don’t repair or dispose of key evidence until your lawyer advises. Vehicles, tires, child seats, or failed components can be inspected, photographed, and tested to establish defect, misuse, or maintenance issues.
Proving the other party’s liability and your injuries in an insurance claim or personal injury lawsuit takes work. You need to investigate your case independently. Don’t rely on what the insurance company said they found.
