What do I need to do to prove that I have been injured by a dangerous or defective product?

Simply claiming a product was defective in design or production is not adequate for a product liability action. It has to be proven by the plaintiff that the manufacturer was at fault and the product caused the injuries. This includes that the product was used as intended by the manufacturer or the manufacturer should have been able to predict that the product could be "misused" and a warning should have been established in the literature or packaging of the product. The product's possible dangers are the manufacturer's responsibility. It is the plaintiff's responsibility to prove the product was the cause of the injuries with credible evidence. Design defects are much more difficult to prove. It often requires expert testimony and proof that the entire product line is subject to having the same defect, causing unreasonable hazards. Showing that the product was the single cause of the injuries may be complicated. If more than one cause is possible, it must be proven that the product defect was the main reason for the injuries.
