Canonical definition

Vicarious liability is responsibility imposed on a principal or employer for another person's actionable conduct because of their legal relationship, commonly an employee acting within the scope of employment. It is distinct from a claim that the business itself negligently hired, trained, or supervised that person.

Vicarious liability is responsibility that follows a legal relationship. An employer or other principal may be sued for an employee’s or agent’s actionable conduct even when the principal did not personally perform the act. Cornell’s legal definition describes this as imputed liability; the exact test varies with the claim and jurisdiction.

The employer can be in the complaint

Respondeat superior is the familiar employment example: a plaintiff may sue the employee and employer for an act within the scope of employment. A customer injured by a delivery driver, a patient alleging a staff member’s actionable conduct, or a client alleging a professional act by a firm’s employee may name the business because the business is the principal with the resources and legal relationship at issue.

That is different from direct negligence. “The employee harmed me while doing the job” is a vicarious theory. “The business hired an unqualified person, failed to train them, or ignored a warning” alleges the business’s own conduct. The two theories can appear together and may have different defenses, facts, and policy treatment.

Independent contractors change the analysis

The label alone does not answer every agency question, but Cornell’s respondeat-superior explanation notes that independent contractors generally fall outside that doctrine and that control and other facts matter. A hiring company can still face direct negligence, premises, contract, or statutory allegations connected to a contractor’s work. Treating a 1099 form as a liability transfer is not a safe substitute for reviewing the relationship and contract.

Match the allegation to the exposure

The coverage line follows the alleged harm, not the glossary label. A customer claim for third-party bodily injury or property damage may raise a general- liability question. An error in professional advice or a report raises a professional-liability question. Harassment or other employment-practices allegations can implicate EPLI. The policy, exclusions, insured status, and jurisdiction control; vicarious liability by itself is not a coverage grant.

The U.S. Supreme Court’s Ellerth decision is a useful boundary example: federal Title VII employer liability uses agency principles, but its holding is not a universal answer for every tort or every insurance policy. For policy mechanics, keep the sister library’s professional liability example separate from the PDS question: who can sue the business, on what theory, and for whose act?
