A mesothelioma diagnosis often comes decades after the asbestos exposure that caused it. Because the disease can take 20 to 50 years to appear, many patients and families wonder who can be held responsible and how a lawsuit works. In the United States, most mesothelioma claims are filed against the companies that manufactured, sold, or used asbestos-containing products, as well as the employers and property owners who allowed exposure to occur. Understanding the basic types of claims can help you and your family know what to expect.
Who Can Be Named as a Defendant
Mesothelioma lawsuits generally fall into two broad categories: claims against employers and claims against premises owners. In many cases, both types of parties are named in a single lawsuit.
- Employers: Companies that used asbestos in their operations, such as shipyards, construction firms, manufacturing plants, power plants, and automotive repair shops, may be held liable if they failed to provide protective equipment, warn workers of the dangers, or follow safety regulations in place at the time of exposure.
- Premises owners: Property owners who allowed asbestos-containing materials to be present on their land or buildings may face claims if visitors, contractors, or tenants were exposed. This includes owners of older commercial buildings, schools, apartment complexes, and industrial sites.
- Product manufacturers and suppliers: Although not employers or premises owners, companies that made or distributed asbestos-containing products are frequently named as defendants. In many cases, the employer or premises owner is no longer in business, and the manufacturer is the party with available insurance or assets.
Types of Legal Claims
Most mesothelioma lawsuits are based on negligence. To succeed, the plaintiff must show that the defendant had a duty to protect people from asbestos exposure, that the duty was breached, and that the breach caused the illness. Common legal theories include:
- Negligence: Failing to warn about asbestos hazards, failing to provide safe working conditions, or failing to follow industry standards.
- Premises liability: A property owner knew or should have known about asbestos hazards on the property and failed to take reasonable steps to protect visitors or workers.
- Strict liability: In product-related claims, a manufacturer can be held responsible for a defective or dangerous product even if it was not negligent in making it.
What the Legal Process Involves
Mesothelioma cases are typically filed in state court, though some may be brought in federal court. The process generally begins with a detailed review of the patient's work and residential history to identify where and when exposure occurred. Attorneys often use employment records, military service records, and testimony from former coworkers to build the case. Many cases are resolved through settlement, while others proceed to trial. Because statutes of limitations vary by state, it is important to act promptly after a diagnosis.
Practical Steps for Patients and Families
If you or a loved one has been diagnosed with mesothelioma, there are several practical steps you can take:
- Gather any records of employment, military service, or residence that may show where asbestos exposure occurred.
- Keep a list of products, workplaces, and locations where you believe exposure happened.
- Consult with a lawyer who focuses on asbestos and mesothelioma cases. These attorneys typically work on a contingency basis, meaning they are paid only if the case is successful.
- Ask about trust funds. Many asbestos companies have established bankruptcy trust funds to compensate people injured by their products, and these claims may be pursued separately from a lawsuit.
Mesothelioma lawsuits are complex and can take time, but they provide a way for families to seek compensation for medical expenses, lost income, and pain and suffering. Speaking with an experienced attorney early in the process can help clarify your options and ensure that important deadlines are not missed.
