Strong evidence is your most powerful tool. Collect and keep everything: photos of injuries and property damage, the official accident report, all medical records and bills, receipts for related expenses, and a diary documenting your pain and recovery. Proof of lost wages from your employer is also crucial. This documentation creates a clear, undeniable link between the incident and your financial losses, preventing the insurance company from downplaying your claim.

A judge or a jury decides the outcome based on the “preponderance of the evidence” standard. This is a much lower burden of proof than in a criminal case. It essentially means it is more likely than not (greater than 50% certainty) that the defendant’s actions caused the plaintiff’s harm. There is no verdict of “guilty” or “not guilty”; the finding is typically “liable” or “not liable” for the damages claimed.

The law recognizes three core defect types. A manufacturing defect is a flaw that makes one specific product different and more dangerous than others in its line. A design defect means the entire product line is inherently unsafe due to a poor blueprint. A marketing defect involves failures in proper instructions or warnings, failing to alert users to non-obvious risks. Your claim’s path depends on proving which type of defect caused your injury, as the legal tests and evidence required differ for each category.
