Proving negligence is one of the most important parts of any personal injury claim in Florida. Whether you were injured in a car accident, slip and fall, rideshare crash, bicycle collision, or any other incident caused by someone else’s carelessness, the success of your case depends on the strength of your evidence. At Stockwell Law, attorney Marissa Stockwell helps injury victims gather the documentation, records, and proof needed to show exactly how the accident happened and why the at-fault party should be held responsible. The right evidence not only strengthens your claim—it directly impacts how much compensation you may receive for medical bills, lost wages, pain and suffering, and long-term damages.
One of the most critical forms of evidence is the official accident report. In car accident cases, police reports contain key information about the scene, the parties involved, witness statements, and whether the other driver received a citation. For premises liability or slip and fall accidents, incident reports filed with the property owner are equally important. These documents establish an early record of what occurred and help confirm liability. Photographs and videos from the scene also play a major role. Images of vehicle damage, road conditions, hazards, skid marks, injuries, or unsafe property conditions provide clear visual proof that can be difficult for insurance companies to dispute.
Medical records are another foundation of proving negligence because they show the direct link between the accident and your injuries.
Immediate treatment strengthens your case by documenting symptoms, diagnoses, and recommended care. Delaying treatment allows insurers to argue your injuries were unrelated or not as severe. Ongoing medical records, physical therapy notes, imaging results, and specialist evaluations further confirm the extent of your injuries and long-term impact on your health. Witness statements also provide powerful support. Neutral third parties can confirm what they saw, how the accident occurred, and whether the other party behaved negligently, giving your claim additional credibility.
In many cases, expert testimony helps explain complex factors such as accident reconstruction, the severity of injuries, future medical needs, or safety violations. Experts can clarify how a dangerous condition caused your fall or how another driver’s actions directly led to a collision. Additional documentation such as employment records, showing lost wages or reduced earning ability, helps prove financial damages. Surveillance footage, dashcam videos, business camera recordings, or even smartphone videos often become critical in proving negligence, especially when insurance companies attempt to deny fault.
Insurance companies often look for ways to minimize claims by questioning liability, disputing injuries, or suggesting shared fault under Florida’s comparative negligence laws. This is why having Stockwell Law on your side is essential.
