8.1 Negligence, Torts, and Legal Liability

Why Liability Theory Drives the Exam

Liability insurance pays sums the insured becomes legally obligated to pay as damages because of bodily injury (BI) or property damage (PD) suffered by a third party. Before any liability policy responds, the claimant must establish that the insured is legally responsible. That responsibility almost always arises from a tort — a civil wrong, other than breach of contract, for which the law allows a remedy in money damages.

The casualty half of the Property and Casualty (P&C) exam tests the legal scaffolding below far more heavily than candidates expect. Memorize the three tort categories and the four elements of negligence verbatim.

The Three Categories of Torts

Trap: Intentional torts that injure a person are usually excluded under the BI/PD insuring agreement. Some — libel, slander, false arrest, wrongful eviction — are picked up separately as personal and advertising injury under Coverage B of the CGL (covered in 8.4).

The Four Elements of Negligence

Negligence is the basis for the overwhelming majority of liability claims. The claimant must prove all four elements; failure of any one defeats the claim and the insurer owes nothing.

1. Duty — a legal obligation to exercise the care a reasonably prudent person would use under the same circumstances.
2. Breach — failure to meet that standard of care (an act or an omission).
3. Proximate cause (causation) — the breach was the direct, unbroken, foreseeable cause of the harm. An intervening cause can break the chain and relieve the defendant.
4. Damages — actual, measurable harm (injury, dollars) occurred. Near-misses with no harm produce no liability.

A handy mnemonic is "Duty, Breach, Cause, Damages" — sometimes shortened to the four D's of negligence in study aids, but the exam uses these exact four words.

Negligence Per Se and Res Ipsa Loquitur

Two doctrines shift the proof burden and appear on the exam:

• Negligence per se — violating a statute designed to protect the public (e.g., running a red light) is treated as automatic breach of duty. The claimant need not separately prove the standard of care.
• Res ipsa loquitur ("the thing speaks for itself") — when an accident would not normally occur without negligence, and the instrumentality was under the defendant's exclusive control, negligence is inferred. Classic example: a surgical sponge left inside a patient. The burden shifts to the defendant to disprove negligence.

Statutory, Contractual, and Vicarious Liability

Liability does not only arise from one's own carelessness:

• Statutory liability — imposed by law, regardless of fault (e.g., workers compensation statutes make the employer liable for on-the-job injury without proof of negligence).
• Contractual liability — liability assumed by contract, such as a hold-harmless agreement in a lease. The CGL covers liability assumed in an "insured contract" even though it would otherwise be excluded.
• Vicarious liability — responsibility for another person's acts (employer for employee, parent for minor). Covered in detail in 8.2.

Trap: An ordinary contractual indemnity is excluded by the CGL, but the insured-contract exception restores coverage for specific defined agreements (leases of premises, easement agreements, elevator-maintenance contracts, etc.).

The Reasonable-Person Standard in Practice

The standard of care is objective: the law asks what a reasonably prudent person would have done in the same situation, not what the particular defendant subjectively believed was fine. The standard rises for professionals (a physician is held to the care of a competent physician) and for those who hold themselves out as having special skill. Children are generally held to the standard of a child of similar age and experience, except when engaged in an adult activity such as driving.

Why This Matters for the Liability Insurer

The insurer's adjusters and defense counsel evaluate each of the four elements when deciding whether to defend, settle, or litigate. A weak link — say, a missing causation chain or only nominal damages — can convert a six-figure demand into a successful defense. Because the duty to defend is broader than the duty to indemnify, the insurer must still mount a defense whenever the allegations potentially fall within coverage, even if it ultimately proves the insured was not negligent and owes nothing in damages.

Torts, the Four Elements, and Categories of Legal Liability

Liability insurance responds to legal liability, which arises chiefly from torts, civil wrongs other than breach of contract. Torts divide into three classes the exam tests. Negligence is the failure to exercise the care a reasonable person would, and it is the basis for most covered claims. Intentional torts (assault, battery, libel, slander) are deliberate and are usually excluded from liability coverage because they are not accidental. Absolute (strict) liability imposes responsibility without fault for inherently dangerous activities, such as blasting or keeping wild animals, and for defective products.

Negligence requires four elements, and an examiner will remove one to defeat the claim. There must be a legal duty owed to the plaintiff, a breach of that duty, proximate cause linking the breach to the harm, and actual damages. Knock out any element, such as no duty owed or an intervening cause that breaks proximate causation, and there is no negligence and no covered liability.

Liability can also be imposed by other doctrines. Vicarious liability holds one party responsible for another's acts (an employer for an employee under respondeat superior). Contractual liability is assumed by agreement, such as a hold-harmless clause, and is covered only when it qualifies as an insured contract. Liability of others assumed by contract and statutory liability (imposed by law, like workers compensation) round out the categories.

Worked scenario: a store leaves a wet floor unmarked and a customer slips and breaks an arm. The store owed a duty to keep premises reasonably safe, breached it by failing to warn, the breach proximately caused the fall, and the customer suffered damages. All four elements are met, so negligence is established and the CGL responds. If the customer had ignored a clearly posted wet-floor sign, the duty/breach analysis (and comparative-fault defenses) would change the outcome. Walking a fact pattern through the four elements is the core legal-liability skill.

Key Takeaways

Liability insurance covers legal liability arising mainly from torts, which are negligence, intentional torts (usually excluded), or absolute/strict liability for dangerous activities and defective products. Negligence requires duty, breach, proximate cause, and damages, and removing any element defeats the claim. Liability may also be vicarious, contractual (covered only as an insured contract), or statutory. The duty to defend is broader than the duty to indemnify, so the insurer defends whenever allegations potentially fall within coverage.
