A product liability lawyer represents clients in product liability lawsuits and negotiations. A product liability lawsuit may be brought when a defective product has harmed a consumer. Potential defendants include the product manufacturer, distributor and retailer. Different jurisdictions have different theories of product liability law. Some jurisdictions allow plaintiffs to sue under a theory of negligence, some jurisdictions allow plaintiffs to sue for a breach of warranty of fitness and the majority of U.S. jurisdictions allow plaintiffs to sue under a strict liability theory. A product liability lawyer can help a potential plaintiff understand the rules in the jurisdiction where his or her lawsuit may be brought. A product liability lawyer may also be known as a defective products attorney.
