A defendant is the person or company being sued in a civil lawsuit. In an asbestos case, defendants are typically the businesses a patient's legal team has identified as responsible for the asbestos exposures that caused the illness. A single asbestos case usually names many defendants, not just one.
Origin
From the Old French defendant, the present participle of defendre ("to defend"), itself from the Latin defendere, meaning to ward off or protect against. The word has been used in English legal proceedings since the 14th century to describe the party answering a claim.
Significance in Asbestos Context
For a patient, the list of defendants in your case reflects every company your legal team can tie to your exposure, manufacturers of asbestos products you worked with, employers, contractors, premises owners where you worked, suppliers, and sometimes equipment makers whose products required asbestos parts. Because many original asbestos manufacturers went bankrupt and now pay through asbestos trusts rather than lawsuits, the living defendants in your case are often secondary players (distributors, installers, site owners, or makers of replacement parts). Each defendant will typically deny responsibility, challenge whether their product was actually present at your jobsites, and argue that someone else's asbestos caused your disease, which is why detailed work history and product identification matter so much. The strength of your case against each defendant depends on documentary proof, witness testimony, and sometimes scientific fiber analysis linking that company's product to your exposure.
Example Sentence
The complaint named eighteen defendants, including the shipyard where he worked in the 1970s and several manufacturers of the insulation products his crew handled daily.

Notes
- Write down every job, jobsite, and product you remember being exposed to (brand names, employers, dates, and coworkers) because this information drives which defendants can be named in your case.
- Preserve pay stubs, union records, military service records (DD-214), tax records, and old photographs; these documents help your attorneys identify and prove claims against specific defendants.
- Ask your legal team which defendants are still solvent and litigating versus which ones are bankrupt and paying through trusts. The two tracks proceed differently and on different timelines.
- Expect each defendant to take your deposition seriously; you may be questioned in detail about that specific company's products, and thorough preparation with your attorney is essential.
