Virginia defective product injury lawyers Rick Shapiro and Kevin Duffan talk about the mistaken belief that a receipt is required to establish a product defect injury claim. That is NOT accurate. This is because, in many instances, the injured party is not the original purchasor of the product. Nevertheless, you will need some form of evidence to validate your claim. This evidence could include eye witnesses, an incident report, or physical evidence such as the defective product itself.
