15.3 Professional Liability and Errors & Omissions

Why Professional Liability Exists

A standard CGL covers bodily injury and property damage but expressly excludes liability arising from the rendering or failure to render professional services. A professional who gives flawed advice causes economic (financial) harm, not a slip-and-fall. That gap is filled by Professional Liability insurance, also called Errors & Omissions (E&O) for non-medical professions and Malpractice for medical ones.

The defining features:

• Covers negligent acts, errors, or omissions in performing professional services for others
• Pays for economic loss the client suffers, plus defense costs
• Almost always written on a claims-made basis, not occurrence
• Defense costs are usually inside the limits (eroding/wasting limits)

Claims-Made Triggers, Retroactive Date, and Tail

Unlike occurrence policies (which respond to events that occur during the term no matter when reported), a claims-made policy responds only when both conditions are met: the injury occurs on or after the retroactive date, AND the claim is first made during the policy period (or an extended reporting period).

Two dates control coverage:

• Retroactive date - the earliest date of a wrongful act the policy will cover. Anything before it is excluded, even if reported during the term.
• Extended Reporting Period (ERP), or "tail" - lets the insured report claims after expiration for acts committed before expiration. A Basic (mini) tail is automatic (often 60 days); a Supplemental tail is purchased.

Worked example. A policy runs 1/1/2026-1/1/2027 with a retroactive date of 1/1/2023. A patient was injured 6/1/2022 but files suit 9/1/2026.

• The claim is first made during the term - good
• But the act (6/1/2022) is before the 1/1/2023 retroactive date - NOT covered

Defense, Consent-to-Settle, and Limits

Professional liability defense is expensive, and most forms make defense costs erode the limit.

Worked example. A lawyers E&O policy has a $1,000,000 limit with defense inside the limits. The carrier spends $300,000 defending the matter and then settles for $800,000.

• Defense $300,000 + settlement $800,000 = $1,100,000 demanded
• Policy caps at $1,000,000
• Insurer pays the $1,000,000 limit; the insured owes the remaining $100,000 out of pocket

Many professional forms contain a consent-to-settle ("hammer") clause: the insurer cannot settle without the insured's consent. If the insured refuses a settlement the insurer recommends, a hammer clause caps the insurer's liability at the amount it could have settled for plus defense to that point - the insured bears any excess.

Exam trap: Professional liability does NOT require intent or even gross negligence - simple negligence (failure to meet the professional standard of care) triggers coverage. Intentional or fraudulent acts ARE excluded.

Claims-Made Year Steps and Maturity

A newly-purchased claims-made policy is cheapest in its first year because the retroactive date equals the inception date - it can only cover acts during that single year. As years pass, the gap between the retroactive date and the present widens, exposing more prior acts, so the premium steps up until the policy reaches maturity (typically year 5), when it is priced like a comparable occurrence policy.

This is why never advance the retroactive date - doing so wipes out coverage for all prior acts. A new carrier that offers a later retroactive date is effectively cheaper because it covers less.

Tail vs. Nose (Prior Acts) Coverage

When an insured switches carriers, two options preserve continuity: buying a tail (ERP) on the expiring policy, or buying prior-acts ("nose") coverage from the new carrier that sets the retroactive date back to the old policy's date.

Exam trap: A retiring professional should buy the tail on the expiring policy, because no new policy is being purchased to provide nose coverage. An ERP often runs a flat premium (e.g., 150%-300% of the expiring annual premium) and may be available for an unlimited reporting window.

Professional Liability: Errors & Omissions and Malpractice

Professional liability insures against claims arising from the rendering of, or failure to render, professional services — covering economic loss caused by negligent acts, errors, or omissions rather than the bodily injury/property damage that the CGL handles. This is the crucial distinction: a CGL responds to a slip-and-fall in an accountant's office, but only professional liability (E&O) responds when the accountant's negligent tax advice costs a client money.

Professional liability for those whose errors cause bodily injury (physicians, dentists) is usually called malpractice; for advisors and service providers whose errors cause financial harm (accountants, lawyers, insurance agents, architects, technology firms) it is called errors & omissions (E&O).

Claims-Made Triggers, Defense, and Key Features

Professional liability is almost always written on a claims-made basis because professional errors are long-tail — the harm may surface years after the work — so insurers need the reserving control claims-made provides. The same controls apply: a retroactive date caps how far back covered errors reach, and an Extended Reporting Period (tail) must be available when coverage ends. Many E&O forms include a "consent to settle" (hammer) clause requiring the insured's agreement before the insurer settles — important to professionals whose reputation is at stake.

Distinctive features the exam tests:

• Coverage is for wrongful acts (negligent acts, errors, omissions) in performing professional services, not intentional/dishonest acts or bodily injury/property damage (which belong on the CGL).
• Defense costs are frequently inside the limit on E&O forms (eroding it), unlike the CGL where defense is outside — a key contrast.
• A deductible typically applies, and limits are usually written on a per-claim and aggregate basis.
• Specialized forms exist for nearly every profession: Insurance Agents E&O, Lawyers Professional Liability, Miscellaneous E&O, Technology/Cyber E&O, and Medical Malpractice.

The recurring exam ideas are: E&O covers economic loss from professional negligence, is written claims-made, often pays defense inside the limit, and is the coverage a producer themselves must carry against the risk of giving a client the wrong advice.
