15.3 Professional Liability and Errors & Omissions

Why Professional Liability Is Its Own Line

Professional liability (often sold as Errors & Omissions, E&O) responds to financial harm caused by a failure to perform professional duties competently - bad advice, a missed filing, a design defect, a negligent diagnosis. It fills the gap left by the CGL, which excludes liability arising out of the rendering or failure to render professional services.

Quick Answer: The CGL covers bodily injury and property damage from operations; professional liability covers economic loss from professional mistakes the CGL explicitly excludes.

The key conceptual shift is the trigger of negligence: a professional is held to the standard of care of a reasonably competent member of that profession, not the ordinary-person standard. An accountant who misses a deduction, a lawyer who blows a statute of limitations, or an architect whose design fails is judged against peers.

Occurrence vs. Claims-Made

Most professional liability is written claims-made, not occurrence, and this is the single most-tested concept in the section.

Retroactive date: A claims-made policy covers only wrongful acts that occur on or after the retroactive date AND are reported during the policy period (or tail). Advancing or eliminating the retroactive date destroys prior-acts coverage - a classic trap when an insured switches carriers.

Extended Reporting Period (ERP / 'tail'): When a claims-made policy is not renewed, the insured can buy an ERP to report claims arising from acts before expiration. A basic tail (often 60 days for any claim, plus 5 years for claims from acts already reported) is sometimes automatic; a supplemental tail of 1-3 years or unlimited is purchased.

Common Professional Liability Forms

• Medical malpractice - physicians, hospitals; high-severity, long-tail; almost always claims-made.
• Lawyers professional liability (LPL) - missed deadlines, conflicts of interest.
• Accountants E&O - audit failures, tax errors.
• Architects & engineers (A&E) - design defects; coverage triggers when the defect causes loss, not when CGL-type property damage occurs.
• Real estate, insurance agents E&O - failure to procure coverage, misrepresentation.
• Technology / miscellaneous E&O - software, consulting.

The Defense-Within-Limits Trap

Many E&O policies pay defense costs inside the limit of liability (a 'wasting' or 'eroding' limit), unlike the CGL where defense is usually outside the limit.

Worked example: A consultant has a $1,000,000 claims-made E&O policy with defense inside limits and a $25,000 deductible. Defense costs reach $300,000 and the settlement is $800,000. Total demand on the policy = $1,100,000, but the limit is $1,000,000.

The insurer's exposure is capped at the $1,000,000 limit. Because defense erodes that limit, the indemnity left for settlement is $1,000,000 - $300,000 = $700,000, leaving the insured to fund the remaining $100,000 of the $800,000 settlement - a critical client-counseling point about wasting limits.

Consent-to-Settle and Disciplinary Defense

Many professional liability policies contain a consent-to-settle ("hammer") clause: the insurer cannot settle without the insured's consent, but if the insured refuses a settlement the insurer recommends, the insured may become responsible for amounts above that figure. Medical, legal, and design professionals also value disciplinary/regulatory defense sublimits that pay to defend a licensing-board complaint even when no civil damages are sought.

Trap: Because professional liability is almost always claims-made, advancing or eliminating the retroactive date on renewal destroys prior-acts coverage. When switching carriers, match the retro date or buy a tail - otherwise old work goes uninsured.

Standard of Care and the Line Against the CGL

Professional liability is judged against the standard of care of a reasonably competent member of the profession, not the ordinary-person standard - an architect's design is measured against competent architects. The line against the CGL is sharp: the CGL excludes liability arising from rendering or failing to render professional services, so the E&O policy is the only source of coverage for negligent advice or design that causes economic loss.

Trap: Most professional liability is claims-made with defense inside the limit (a wasting limit), unlike the CGL where defense is outside the limit. A large defense bill on an E&O policy reduces the money left to pay the settlement - a critical client-counseling point and a frequent calculation trap.

The Consent-to-Settle Hammer and Retroactive-Date Care

Many E&O forms add a consent-to-settle ("hammer") clause: the insurer cannot settle without the insured's consent, but if the insured refuses a recommended settlement and the case later resolves for more, the insured may owe the excess plus a share of defense from the refusal point. This protects the professional's reputation while capping the insurer's exposure to the insured's stubbornness.

Trap: Advancing or eliminating the retroactive date at renewal destroys prior-acts coverage - when switching carriers, match the old retro date (nose coverage) or buy a tail, or years of past work go uninsured. E&O is claims-made, so the report date, not the act date, drives which policy responds.
