Frequently Asked Questions
Why is preserving the product so important?
The product itself is the key evidence. Experts need to examine it to determine what made it defective. Without the product, proving your case becomes extremely difficult.
What if I already returned or discarded the product?
The case becomes more challenging but may not be impossible. Records, photos, and similar products may help, but always try to preserve the actual defective item.
Who can be held responsible for defective products?
Potentially the manufacturer, designer, distributor, and retailer. Product liability claims can proceed against any party in the chain of distribution.
Do I need to prove the company was negligent?
California has strict product liability—you may be able to recover even without proving negligence if the product was defective and caused your injury.
What types of defects support claims?
Design defects (product designed unsafely), manufacturing defects (error during production), and warning defects (inadequate instructions or warnings).
