Where the Term Comes From and How It's Used

"Tortfeasor" comes from tort law, the branch of civil law covering wrongful acts that cause injury or loss (as opposed to criminal law or contract disputes). A business becomes a tortfeasor the moment a court, insurer, or opposing attorney is alleging it caused harm, even before liability is proven. It's a role in the claim, not a final verdict.

• Primary tortfeasor: the party whose act most directly caused the harm
• Joint tortfeasors: two or more parties who together caused a single harm

Joint Tortfeasors and Shared Liability

When multiple parties contribute to one incident, such as a general contractor and a subcontractor both bearing some responsibility for a jobsite injury, they can be treated as joint tortfeasors. Depending on the jurisdiction, liability can be allocated proportionally to each party's share of fault, which is exactly the kind of dispute a liability policy and its defense counsel are built to handle.

Why This Matters for a Business Owner

Being named as a tortfeasor in a claim doesn't mean guilt, it means someone has alleged your business caused harm and the matter needs to be defended or resolved. This is precisely the scenario general liability and professional liability policies are designed for: they pay for legal defense and any resulting settlement or judgment, which is why maintaining active coverage protects the business's finances even when the underlying claim is eventually dismissed.
