15.3 Professional Liability and Errors & Omissions

Professional Liability and Errors & Omissions

Professional liability insurance covers losses arising from the rendering or failure to render professional services. It responds to claims of negligence, error, or omission in a professional's work - exposures the standard CGL specifically excludes. The CGL covers bodily injury and property damage from operations, but a financial loss caused by bad advice is a professional exposure.

Two families of professional liability

• Errors & Omissions (E&O): for professionals whose mistakes cause financial harm - insurance agents, accountants, real estate brokers, architects, engineers, attorneys, and technology firms.
• Medical Malpractice (Med Mal): for healthcare providers whose errors cause bodily injury - physicians, surgeons, hospitals, dentists, and nurses.

Both are negligence-based: the plaintiff must show a duty, breach of the professional standard of care, causation, and damages.

Claims-made vs. occurrence triggers

Most professional liability is written claims-made, not occurrence. A claims-made policy responds only if the claim is first made during the policy period (and after any retroactive date). An occurrence policy responds based on when the act happened, regardless of when the claim is reported.

Retroactive date and the tail (ERP)

The retroactive date is the earliest date a wrongful act can occur and still be covered. Acts before it are excluded forever. When a claims-made policy ends, the insured buys an Extended Reporting Period (ERP), or tail, to report claims for acts that happened during the policy term but surface later. A common basic tail runs 60 days automatically with a longer supplemental tail (often 1-5 years) available for extra premium.

Worked scenario

An accountant has a claims-made policy effective 1/1/2024-1/1/2025 with a retroactive date of 1/1/2022. A client sues in March 2025 over a tax error made in 2023. Is there coverage? The act (2023) is after the retroactive date - good. But the claim was made in 2025, after expiration. Coverage exists only if the accountant purchased a tail (ERP); otherwise the claim is uncovered.

Common exam traps

• Professional liability often covers defense costs inside the limit (eroding limits) - defense payments reduce the available limit, unlike a CGL where defense is usually outside the limit.
• Many policies require the insurer's consent to settle; a hammer clause lets the insurer cap its exposure if the insured refuses a recommended settlement.
• Punitive damages and intentional/fraudulent acts are typically excluded.
• A basic 60-day tail is usually automatic at no charge, but it is far too short for slow-developing professional claims; the supplemental tail (1-5 years or longer) must be elected and paid for within a stated window after expiration.

Prior acts and nose coverage

When a professional switches carriers, the new insurer may grant prior acts (nose) coverage by setting the retroactive date back to the original policy's start, so past work stays covered without buying a tail on the old policy. The choice is usually buy a tail (ERP) on the expiring policy or secure prior-acts coverage on the new one - doing neither creates a coverage gap for unreported acts. This nose-vs-tail decision is a frequent exam item.

Insuring agreement and definition of professional services

The heart of a professional liability policy is its definition of professional services. Coverage applies only to acts within that defined scope. An insurance agent's E&O covers errors in placing or servicing coverage; it does not cover unrelated business advice. A misstep outside the defined services is not a covered wrongful act, so applicants must ensure the definition matches their actual practice and any side ventures.

Limits, deductibles, and vicarious liability

Professional policies state both a per-claim limit and an aggregate limit. Many include a per-claim deductible that, combined with eroding defense costs, can sharply reduce net recovery. Firms also face vicarious liability for employees' professional errors, so a firm-wide policy should name the entity and its professionals as insureds. A sole practitioner who adds staff must update the policy to cover the expanded exposure.

Eroding-limits worked example

A consultant has a $1,000,000 per-claim E&O limit with defense inside the limit and a $25,000 deductible. A claim settles for $600,000 with $200,000 in defense costs. The insurer's combined payout is $600,000 + $200,000 = $800,000, less the $25,000 deductible, so it pays $775,000. Critically, defense ate into the limit, so only $1,000,000 - $800,000 = $200,000 remains for any further claim that year - a sharp contrast with the CGL's outside-the-limit defense.

Common professional liability exclusions

Beyond punitive damages and dishonesty, professional forms commonly exclude bodily injury and property damage (those belong to the CGL or med-mal), prior known claims or circumstances disclosed or knowable at inception, insured-versus-insured disputes, and services rendered while uninsured before the retroactive date. Knowing what the professional policy does not cover is as important on the exam as knowing what it does, because gaps often route to the CGL or remain uninsured.
