8.1 Negligence, Torts, and Legal Liability

What Liability Insurance Covers

Liability insurance pays sums the insured becomes legally obligated to pay as damages because a third party suffered bodily injury (BI) or property damage (PD). It is the single largest topic in the casualty half of the national Property & Casualty (P&C) exam, and almost every question turns on one idea: liability is third-party coverage.

Exam trap: If a question describes the insurer paying the named insured's own loss, it is property/first-party coverage — never liability.

Three Branches of Tort Law

A tort is a civil (not criminal) wrong, other than breach of contract, for which the law provides a remedy of money damages. Tort liability is the principal exposure liability insurance addresses.

• Negligence — the failure to use the care a reasonably prudent person would use. This is unintentional and is the core of liability coverage.
• Intentional torts — assault, battery, libel, slander, false arrest. These are deliberate acts and are generally excluded from liability coverage (though personal & advertising injury picks up a few).
• Strict (absolute) liability — liability imposed without proof of negligence for inherently dangerous activities (blasting, keeping wild animals) and for defective products under products-liability law.

Tort vs. Criminal vs. Contractual

Damages in tort are paid to the injured party; criminal penalties (fines, jail) are paid to the state and are never insurable. A third source — contractual liability — arises when the insured assumes another party's liability under a written contract (a hold-harmless agreement).

The Four Elements of Negligence

To recover, a claimant must prove all four elements. The exam loves to remove one element and ask whether liability exists — the answer is always "no."

1. Duty owed — a legal obligation to exercise a reasonable standard of care toward others.
2. Breach of duty — failure to meet that standard (an act or omission).
3. Proximate cause — an unbroken chain of causation linking the breach to the harm; the harm was a foreseeable result.
4. Damages — actual, measurable harm (medical bills, lost wages, property repair).

Memory aid: D-B-C-D — Duty, Breach, Causation, Damages. No damages = no negligence claim, even if the conduct was careless.

Standard of Care

The benchmark is the reasonably prudent person acting under similar circumstances. Professionals (physicians, accountants) are held to a higher standard of care measured against others in their profession — the basis for professional liability (malpractice/E&O).

The Four Elements of Negligence

Most casualty claims rest on negligence, and the exam requires all four elements be present for liability to attach:

Torts fall into three categories: negligence (unintentional), intentional torts (assault, libel, slander - generally excluded by liability policies), and absolute/strict liability (liability without fault, as for ultrahazardous activities or, in some states, dog bites and defective products).

Exam trap: All four elements must exist - if any is missing (e.g., no duty, or harm with no proximate cause), there is no negligence liability. Res ipsa loquitur ("the thing speaks for itself") shifts the burden to the defendant when the harm could only have occurred through someone's negligence and the instrumentality was in the defendant's control. Strict (absolute) liability needs no proof of fault - common on the exam for product, animal, and abnormally dangerous activity claims.

Liability Arising by Contract

The insured can also become liable by assuming another party's obligations in a contract — for example, a tenant who agrees to indemnify a landlord (a hold-harmless agreement).

• Limited hold-harmless — the indemnitor assumes liability only for its own negligence.
• Intermediate hold-harmless — assumes liability for the joint negligence of both parties.
• Broad hold-harmless — assumes liability for all loss, including the indemnitee's sole negligence.

The Commercial General Liability (CGL) Coverage A excludes contractually assumed liability except liability assumed under an “insured contract” — a defined list (leases of premises, sidetrack agreements, easement agreements, elevator-maintenance agreements, and that part of any contract assuming another's tort liability). Statutory liability — e.g., workers compensation and financial responsibility laws — is a fourth source imposed directly by statute, no negligence required.

The Two Duties Owed by the Insurer

When a covered suit is filed, a liability insurer owes the insured two separate duties — a distinction the exam tests directly.

• Duty to defend — the insurer hires and pays for the attorney and controls the defense. This duty is broader than the duty to indemnify: it is triggered whenever the allegations even potentially fall within coverage, so the insurer must defend a suit that is groundless, false, or fraudulent.
• Duty to indemnify — the insurer pays damages the insured is legally obligated to pay, up to the policy limit, only once liability is actually established by judgment or settlement.

Defense-cost trap: On most personal lines, defense costs are supplementary payments paid in addition to the limit. On many commercial liability forms, defense costs are paid inside the limit, eroding the money available for damages. The duty to defend ends once the limit is exhausted by payment of judgments or settlements.
