Casualty Insurance Basics: Practice Questions & Explanations

Casualty (liability) insurance protects the insured from financial responsibility when they are legally liable for harm to a third party. The insurer pays on behalf of the insured for: damages owed to the third party (settlement or judgment for bodily injury or property damage), defense costs (attorney fees, court costs, expert witnesses), and related expenses. This is distinct from property insurance, which pays the insured for damage to their own property. Casualty insurance includes auto liability, general liability, professional liability, umbrella, and workers compensation. The insured is the 'first party'; the insurer is the 'second party'; the injured claimant is the 'third party' — hence the term 'third-party liability'. Without liability insurance, a single negligence claim can financially ruin an individual or business.

Negligence is the legal basis for most liability claims. To establish negligence, the plaintiff must prove four elements (DBCD): (1) Duty — the defendant owed the plaintiff a legal duty of care (e.g., drivers owe other road users a duty to drive carefully); (2) Breach — the defendant breached that duty by acting unreasonably under the circumstances; (3) Causation — the breach actually and proximately caused the plaintiff's harm (both 'but for' causation and reasonably foreseeable consequences); (4) Damages — the plaintiff suffered actual harm (bodily injury, property damage, economic loss). All four elements must be proven; failure on any one defeats the claim. Negligence is distinct from intentional torts (deliberate harm) and strict liability (responsibility without fault, as in some product liability or animal owner cases). Liability insurance covers negligence claims; intentional acts are typically excluded.

Negligence per se applies when a defendant violated a statute designed to protect the public from the type of harm that occurred. In these cases, the violation itself establishes the negligence element — the plaintiff doesn't need to separately argue what a 'reasonable person' would have done. Example: a driver who ran a red light (violating a traffic statute) and hit a pedestrian is negligent per se — the statute violation establishes negligence. The plaintiff still needs to prove causation and damages.

Comparative negligence allows plaintiffs who are partially at fault to still recover — but their recovery is reduced by their percentage of fault. PURE comparative negligence: plaintiff can recover even if 99% at fault (recovery = damages × [1 - plaintiff's %]). MODIFIED comparative negligence: plaintiff can recover only if their fault is below a threshold (typically 50% or 51%). Example: $100,000 damages; plaintiff 30% at fault; recovery = $70,000 (pure) or $70,000 (modified, since 30% < 50%). Most states use modified comparative negligence.

LIABILITY INSURANCE covers the insured's LEGAL RESPONSIBILITY for harm they cause to OTHERS (third parties). It covers: BODILY INJURY and PROPERTY DAMAGE to third parties; the cost of legal DEFENSE (the insurer's duty to defend); and DAMAGES the insured is legally obligated to pay (up to policy limits). It does NOT cover the insured's own property or injuries (those are first-party coverages). THIRD-PARTY coverage: Liability protects against claims by others; the injured third party is not a party to the policy but benefits from it.

Duty to defend: Usually broader than the duty to indemnify — the insurer must defend even groundless suits within coverage. Casualty insurance centers on liability — the legal obligation to pay for harm to others; understanding what liability coverage includes (third-party injury/damage, defense, damages) is fundamental casualty insurance knowledge.

Deductible: The amount the INSURED must pay OUT OF POCKET on a covered loss BEFORE the insurer pays.

Example: With a $500 deductible on a $3,000 covered loss, the insured pays $500 and the insurer pays $2,500.

Purpose: Reduces the number of small claims (the insured handles minor losses); lowers the insurer's costs and thus the PREMIUM (higher deductible = lower premium, and vice versa); gives the insured a stake in preventing losses; COMMON in: auto physical damage (collision/comprehensive), property coverage; LIABILITY coverage typically has NO deductible (or different structures); SELF-INSURED RETENTION (SIR): Similar concept in some commercial policies; CHOOSING a deductible: Balance lower premiums (higher deductible) against affordable out-of-pocket cost at claim time; deductibles are a fundamental policy provision on the casualty exam — the insured's out-of-pocket share that reduces small claims and affects the premium.

COMPENSATORY vs PUNITIVE DAMAGES:

Compensatory damages: REIMBURSE the injured party for actual losses; SPECIAL damages (economic): medical bills, lost wages, property repair — measurable; GENERAL damages (non-economic): pain and suffering, emotional distress — harder to quantify; goal is to make the injured party 'whole'.

Punitive damages: Awarded to PUNISH especially egregious, malicious, or reckless conduct and to DETER similar behavior; beyond compensating the victim; awarded in cases of gross misconduct.

Insurability: Compensatory damages are generally covered by liability insurance; PUNITIVE damages are OFTEN NOT INSURABLE (public policy in many states prohibits insuring punitive damages, so the wrongdoer feels the punishment) — varies by state; liability claims valuation considers both; understanding the distinction (compensatory = make whole; punitive = punish/deter, often uninsurable) is important liability/casualty exam content affecting coverage and claim exposure.

PER OCCURRENCE vs AGGREGATE LIMITS in liability policies:

Per occurrence limit: The maximum the insurer will pay for any SINGLE claim or occurrence (e.g., $1,000,000 per occurrence).

Aggregate limit: The maximum the insurer will pay for ALL covered claims COMBINED during the entire policy period (e.g., $2,000,000 aggregate).

Example: A '$1M/$2M' CGL policy pays up to $1M for any one occurrence, but no more than $2M total for all occurrences in the policy year; once the aggregate is exhausted, no more coverage that period (even if individual claims are within the per-occurrence limit); SPLIT LIMITS in auto: e.g., 100/300/50 = $100K per person / $300K per accident (bodily injury) / $50K property damage; COMBINED SINGLE LIMIT (CSL): One limit per occurrence for both BI and PD; understanding how per-occurrence and aggregate limits work together (single claim cap vs total period cap) is important policy-provision knowledge on the casualty exam — it determines the insurer's maximum exposure per claim and per policy period.

Liability insurance, a core part of casualty coverage, protects the insured against claims that they are legally responsible for causing bodily injury or property damage to a third party — paying both the damages owed (up to policy limits) and the cost of legal defense. Property insurance, by contrast, covers physical damage to the insured's own property. Many policies (like auto and homeowners) combine both. The key distinction is whose loss is covered: liability covers harm the insured causes to others, while property covers the insured's own property. Understanding this fundamental difference is essential casualty insurance content.

Negligence is the failure to exercise the degree of care that a reasonably prudent person would use under similar circumstances, which causes harm to another person or their property. It is the legal basis for most liability claims. To establish negligence, four elements are generally required: a duty of care owed, a breach of that duty, causation (the breach caused the harm), and actual damages. Liability insurance responds to claims arising from the insured's negligence. Understanding negligence and its elements is foundational to casualty insurance, because the coverage exists to protect insureds from the financial consequences of being found negligent.

Utmost good faith (uberrimae fidei) is the principle that an insurance contract requires a higher standard of honesty than ordinary commercial contracts, with both parties — especially the applicant — obligated to disclose all material facts truthfully. The insured must honestly disclose information the insurer needs to assess risk (since the insurer relies on it for underwriting), and the insurer must deal fairly with the insured. Breaches can involve concealment (failing to disclose a material fact) or misrepresentation (stating a material falsehood), which may void coverage. This principle underlies the duty of honest disclosure in applications. Understanding utmost good faith is foundational across all insurance lines.
