8.1 Negligence, Torts, and Legal Liability

Liability insurance pays for third-party claims — harm the insured legally causes to someone else's body or property. Unlike property (first-party) coverage, a liability claim only triggers payment when the insured is legally liable. Understanding how legal liability arises is therefore the foundation of every casualty coverage on the exam, from the Personal Auto Policy (PAP) Part A to the ISO Commercial General Liability (CGL), form CG 00 01.

Sources of Legal Liability

Liability can attach three ways, and the exam expects you to distinguish them:

Most tested claims arise in tort. Torts split into three branches: negligence (the dominant one), intentional torts (assault, libel, slander), and absolute/strict liability (imposed without fault, as in keeping wild animals or certain product defects).

The Four Elements of Negligence

Negligence is the failure to exercise the degree of care a reasonably prudent person would use under the same circumstances. To win, a plaintiff must prove all four elements — missing even one defeats the claim:

1. Duty — the defendant owed a legal duty of care to the plaintiff.
2. Breach — the defendant breached that duty (did something a prudent person would not, or failed to do something they should).
3. Causation — the breach was the proximate cause of the harm (an unbroken chain, no superseding event).
4. Damages — the plaintiff suffered actual, measurable injury or loss.

A classic exam trap: a defendant was careless but no one was harmed. Because damages are missing, there is no negligence and no covered claim. Carelessness alone is never enough.

Standard of Care and Special Duties

The reasonably prudent person standard flexes with circumstances. A professional (physician, accountant, insurance producer) is held to the higher standard of their profession — failing it is malpractice, covered by professional liability / errors & omissions (E&O), not the CGL. Premises owners owe graduated duties depending on who enters:

• Invitee (customer): the highest duty — inspect for and warn of hazards.
• Licensee (social guest): warn of known dangers.
• Trespasser: only a duty not to willfully injure (children draw the higher attractive nuisance doctrine).

Negligence Per Se and Res Ipsa Loquitur

Two doctrines shortcut the proof of negligence and appear as distractors:

• Negligence per se — violating a safety statute (running a red light) is itself proof of breach; the plaintiff need not separately establish the standard.
• Res ipsa loquitur ("the thing speaks for itself") — when an accident could not normally occur without negligence and the instrumentality was in the defendant's exclusive control (a sponge left in a patient), negligence is inferred, shifting the burden to the defendant.

Why This Matters for Coverage

The CGL insuring agreement (Coverage A) promises to pay sums the insured becomes legally obligated to pay as damages because of bodily injury or property damage — and to provide a defense. No legal liability, no obligation to pay. That is why adjusters first analyze the tort, then the policy.

Intentional Torts and Strict Liability

Negligence is unintentional, but two other tort branches still drive insurance questions. Intentional torts are deliberate acts — assault, battery, false imprisonment, defamation (libel/slander), and invasion of privacy. The CGL excludes expected or intended bodily injury under Coverage A, but several intentional offenses are deliberately picked back up as personal and advertising injury under Coverage B (covered in 8.4). The exam wants you to know that 'intentional = excluded' is too simple.

Strict (absolute) liability imposes responsibility without proof of fault or negligence. It applies to inherently dangerous activities (blasting, storing explosives, keeping wild animals) and to product liability under many state doctrines: a manufacturer can be liable for a defective product that injures a user even if it exercised all reasonable care. Because no negligence need be shown, the four-element test does not apply — only that the product was defective and caused harm.

Liberalizing and Burden-of-Proof Concepts

The plaintiff carries the burden of proof in a civil case, but only to a preponderance of the evidence (more likely than not, roughly 51%) — a far lighter burden than the 'beyond a reasonable doubt' standard of criminal law. This lower bar is why an insured can be acquitted criminally yet still lose a civil liability suit on the same facts.

For producers, the practical message is that liability exposure is broad: clients can be sued for negligence, intentional offenses, and strict-liability product claims, and only some of these are covered without endorsement. Matching the type of wrong to the right policy — CGL Coverage A or B, E&O, product liability, or umbrella — is the core skill these questions test.
