15.3 Professional Liability and Errors & Omissions
Key Takeaways
- Professional liability (E&O) covers economic loss caused by negligent acts, errors, or omissions in rendering professional services; it fills the CGL gap because the CGL bodily-injury/property-damage trigger does not reach pure financial harm from bad advice.
- Most E&O and malpractice policies are written on a claims-made basis with a retroactive date; only claims first made during the policy period for acts after the retro date are covered.
- An Extended Reporting Period (tail) lets a claims-made insured report claims after the policy ends for pre-expiration acts; a basic (mini) tail is usually 60 days automatic, with a supplemental tail purchased for longer.
- Medical malpractice, legal malpractice, and miscellaneous E&O typically pay defense costs INSIDE the limit (eroding/wasting limits) unlike the CGL where defense is outside the limit.
- Many professional policies contain a consent-to-settle (hammer) clause: if the insured refuses a settlement the insurer recommends, the insurer's liability is capped at the settlement amount plus defense to that date.
The Gap the CGL Leaves Open
A Commercial General Liability policy responds to bodily injury and property damage (and personal/advertising injury). It does not cover pure economic loss caused by a professional's negligent advice or service. An accountant who misfiles a return, an architect whose design wastes a client's money, or an insurance agent who fails to bind requested coverage causes financial harm with no bodily injury or property damage - precisely what the CGL excludes via the professional-services exclusion.
Professional liability, also called errors and omissions (E&O) or malpractice (for medical and legal professions), fills this gap. It pays for the insured's negligent act, error, or omission in rendering or failing to render professional services. Key feature: it covers negligence, not the failure to achieve a guaranteed result, and it does not respond to intentional or fraudulent acts.
Claims-Made, Retro Date, and the Tail
Most E&O and malpractice forms are claims-made, not occurrence. Two dates govern coverage:
- Retroactive date: the act must occur on or after this date.
- Policy period: the claim must first be made against the insured during this period (or an extended reporting period).
| Date Element | Rule |
|---|---|
| Act before retro date | NOT covered, regardless of when reported |
| Act after retro, claim during period | COVERED |
| Act after retro, claim after expiration | Covered only with an Extended Reporting Period (tail) |
An Extended Reporting Period (ERP) or tail lets the insured report, after the policy ends, claims arising from acts committed during the policy term. A basic/mini-tail (often 60 days, automatic) gives a short reporting window; a supplemental tail is purchased for a longer period (1, 3, 5 years, or unlimited). Switching carriers without a tail or matching retro date is the classic way a professional ends up uninsured for a late-reported claim.
Defense Costs and the Hammer Clause
Two cost features distinguish professional liability from the CGL:
Defense inside the limit (eroding/wasting limits). In the CGL, defense costs are paid in addition to the limit. In most E&O and malpractice policies, defense costs reduce the limit. A $1,000,000 limit with $300,000 of defense already spent leaves only $700,000 for indemnity. The exam loves this contrast.
Consent-to-settle / hammer clause. Reputation-sensitive professionals (doctors, lawyers) often want to fight rather than settle. A consent-to-settle clause requires the insured's agreement to settle. The hammer clause is the counterweight: if the insurer recommends a settlement the insured refuses, the insurer's liability is capped at the recommended settlement amount plus defense costs incurred to that date. Any judgment above that becomes the insured's problem.
| Feature | CGL | Professional Liability |
|---|---|---|
| Trigger | BI/PD occurrence | Negligent professional act |
| Form basis | Usually occurrence | Usually claims-made |
| Defense costs | Outside the limit | Usually inside the limit |
| Settlement control | Insurer | Often insured (consent) with hammer cap |
An E&O policy has a retroactive date of 1/1/2024 and a policy period of 1/1/2026 to 1/1/2027. A negligent act committed 6/1/2023 results in a claim made against the insured on 3/1/2026. Is the claim covered?
A physician's malpractice insurer recommends settling a suit for $400,000. The physician refuses, wanting to protect his reputation. The case goes to trial and a $900,000 judgment is entered. Under a typical hammer clause, how is the insurer's payment limited?
Specialized Professional Lines and Key Distinctions
Professional liability (errors & omissions) covers economic loss from a professional's negligent acts, errors, or omissions in rendering professional services — not the bodily injury/property damage the CGL handles. Specialized forms exist by profession:
| Profession | Common name |
|---|---|
| Physicians/hospitals | Medical malpractice |
| Attorneys | Legal malpractice / lawyers E&O |
| Accountants/architects/engineers | Professional liability / E&O |
| Insurance agents | Agents E&O |
| Directors/officers | D&O (management liability) |
Most professional liability is written claims-made with a retroactive date, and many medical and other forms require the insured's consent to settle (or include a hammer clause penalizing refusal to settle). Trap: professional liability covers financial harm from rendering (or failing to render) professional services — it does not require bodily injury, distinguishing it from the CGL, which covers BI/PD/personal injury but excludes the rendering of professional services.
How does professional liability (E&O) coverage primarily differ from a Commercial General Liability policy?
The Hammer Clause and Consent-to-Settle in Practice
Many professional liability policies give the insured a consent-to-settle right because a settlement can damage a professional's reputation. To balance this, insurers use a hammer clause (also called a settlement cap): if the insurer recommends settling within the limit and the insured refuses, the insurer's liability is capped at the amount for which the claim could have settled, plus defense costs to that date — the insured absorbs any excess.
| Clause variant | Effect of insured's refusal to settle |
|---|---|
| Full (100%) hammer | Insurer's payment capped at the proposed settlement + defense to date |
| Modified (e.g., 50/50, 70/30) hammer | Insured shares the excess above the proposed settlement |
| No hammer / soft consent | Insured controls settlement; rare and costly |
Professional liability is almost always claims-made with a retroactive date, and defense costs typically erode the limit ("defense within limits" / wasting limits) — unlike the CGL, where defense is usually outside the limit.
Exam tip: the hammer clause penalizes an insured who blocks a reasonable settlement; and in many E&O/D&O forms, defense costs reduce the limit available for the judgment — a key contrast with CGL supplementary payments.
