Product Liability
Legal information last reviewed: July 3, 2026
Product liability holds manufacturers, distributors, and sellers responsible when a defective product injures someone. Unlike most negligence claims, many product cases don't require proving anyone was careless — just that the product was defective and the defect caused the injury.
Three types of defects
A manufacturing defect means something went wrong making this specific unit, like a contaminated batch. A design defect means the entire product line is inherently unsafe even when made correctly. A marketing or warning defect means the product failed to warn of a non-obvious risk or provide adequate instructions.
Strict liability
Many states apply strict liability to product defect claims, meaning the injured person doesn't have to prove the manufacturer was careless — only that the product was defective when it left the manufacturer's control and that the defect caused the injury.
Who can be liable
The manufacturer, a component maker, a distributor, and the retailer can all potentially be named, though the exact rules on which parties in the chain of distribution can be held liable vary by state.
Proving the case
This usually requires keeping the product itself rather than discarding or repairing it, documenting how it was used, and often expert testimony explaining how and why it failed.
Recalls and misuse
A recall is strong evidence a problem existed but isn't required to bring a claim, and a product that was never recalled can still be found defective in court. Using a product in a reasonably foreseeable but unintended way generally doesn't defeat a claim; clearly unreasonable misuse can.
When to hire a lawyer
Product cases require expert analysis of how and why something failed, so get a lawyer involved early, before the product is discarded, altered, or lost. This is not a do-it-yourself claim in almost any situation involving a real injury.
Frequently asked questions
- Do I have to prove the manufacturer was careless?
- Often no. Many states let you recover under strict liability by showing the product was defective and caused your injury, without proving negligence.
- What should I do with the defective product?
- Keep it exactly as it was at the time of injury and don't attempt repairs — it's often the single most important piece of evidence.
- Does a recall mean I automatically win my case?
- No, but it's strong supporting evidence. You still need to show the defect caused your specific injury.
- Can I sue the store where I bought it, not just the manufacturer?
- Often yes — retailers and distributors in the chain of sale can potentially be liable, though ultimate responsibility often flows back to the manufacturer.
- How long do I have to file a product liability claim?
- Governed by your state's general personal injury statute of limitations, though some states have separate rules for product cases — check early.
- What if I was using the product in a way it wasn't intended for?
- Unintended but foreseeable uses generally don't bar a claim; clearly unreasonable misuse can defeat one.
