15.3 Professional Liability and Errors & Omissions
Key Takeaways
- Professional liability (errors & omissions) covers economic harm caused by a professional's negligent act, error, or omission in rendering or failing to render professional services — it responds to financial loss, not the bodily injury/property damage that the CGL handles
- Most E&O and medical malpractice policies are written claims-made, meaning the claim must be both made against the insured and reported during the policy period (or an extended reporting period), and a retroactive date bars acts occurring earlier
- Medical malpractice is the classic professional liability line; the consent-to-settle ('hammer') clause lets the insurer reduce its payout if the insured refuses a recommended settlement
- Claims-made policies use the retroactive date to fix the earliest covered act and offer tail coverage (Extended Reporting Period / ERP) to report claims after the policy ends; occurrence policies trigger on when the act happened
- Professional liability generally excludes intentional/dishonest acts, bodily injury/property damage (covered by CGL), and is typically defense-within-limits so legal costs erode the limit of liability
What Professional Liability Covers
Professional liability, also called errors & omissions (E&O) or malpractice, pays for economic loss a client suffers because of a professional's negligent act, error, or omission in performing — or failing to perform — professional services. It fills the gap left by the CGL, which covers bodily injury and property damage but excludes the rendering of professional services.
Quick Answer: Professional liability covers financial harm from a professional's mistakes; the CGL covers bodily injury and property damage. A wrong tax filing is E&O; a client slipping in the lobby is CGL.
Lines include medical malpractice (physicians, hospitals), legal malpractice, accountants E&O, insurance-agents E&O, architects/engineers, and miscellaneous E&O for technology and consulting firms.
Claims-Made vs. Occurrence Triggers
Most E&O and malpractice policies are written on a claims-made basis, in contrast to the occurrence trigger used by most CGLs.
| Claims-Made | Occurrence | |
|---|---|---|
| Trigger | Claim is made and reported during the policy period | The injury/act occurs during the period |
| When act happened | Must be on/after the retroactive date | Any time during the period |
| Late-reported claims | Need a tail (ERP) to report after expiration | Reportable whenever discovered |
| Pricing in early years | Lower; rises as exposure 'matures' | Level |
Retroactive Date and Tail Coverage
The retroactive date is the bright line of a claims-made policy: acts before it are not covered, even if the claim arrives during the policy period. When a claims-made policy ends, the insured can buy an Extended Reporting Period (ERP), or tail, to report claims for acts that happened before expiration but surface afterward.
- Basic (mini) tail — a short automatic window (often 30–60 days).
- Supplemental (full) tail — purchased; can be unlimited in time for reporting pre-expiration acts.
Moving from one claims-made insurer to another, an insured can instead buy prior-acts (nose) coverage to keep the old retroactive date alive.
Medical Malpractice and the Consent-to-Settle (Hammer) Clause
Medical malpractice is the prototypical professional liability line. A distinctive feature is the consent-to-settle clause: the insurer may need the insured physician's consent to settle a claim, protecting the doctor's reputation. The flip side is the "hammer" clause — if the insurer recommends a settlement the insured refuses, the insurer's liability can be capped at the amount it could have settled for, leaving the insured responsible for the excess and defense beyond that point.
Example: An insurer can settle a malpractice suit for $150,000. The physician refuses, the case goes to trial, and the verdict is $500,000. Under a hammer clause, the insurer pays up to the $150,000 it could have settled for (plus defense to that date); the physician may owe the remaining $350,000.
Defense Within Limits — A Costly Feature
Unlike the CGL (where defense is paid in addition to the limit), most professional liability policies are defense within limits (also called eroding or wasting limits): defense costs reduce the limit of liability.
Worked example: A consultant has a $1,000,000 E&O limit, defense within limits. The insurer spends $300,000 defending a claim, then settles for $800,000.
- Available limit at settlement = $1,000,000 − $300,000 defense = $700,000.
- The insurer pays only $700,000 toward the $800,000 settlement; the insured owes the $100,000 shortfall.
Had defense been outside the limit (CGL-style), the full $800,000 settlement would have been paid plus the $300,000 defense.
Standard Exclusions
| Excluded | Reason |
|---|---|
| Intentional, dishonest, or fraudulent acts | Coverage is for negligence, not willful wrongs |
| Bodily injury / property damage | Belongs on the CGL |
| Acts before the retroactive date | Defines the coverage's earliest reach |
| Liability assumed under contract beyond the duty of care | Not a professional-negligence loss |
Common Exam Traps
- CGL excludes professional services — economic-harm mistakes go to E&O, not the CGL.
- Retroactive date bars earlier acts even when the claim is made during the policy period.
- Tail (ERP) lets the insured report late; it does not extend the acts covered beyond the retro date.
- Defense within limits erodes the limit — a settlement plus defense can exceed what the policy pays.
- Hammer clause caps the insurer's payout when the insured refuses a recommended settlement.
Professional Liability vs. General Liability
Professional liability (errors & omissions, E&O) covers claims arising from the rendering of — or failure to render — professional services: bad advice, a missed deadline, a design error, a faulty diagnosis. The CGL specifically excludes professional services, so a professional needs E&O.
The key contrast the exam draws: the CGL covers bodily injury and property damage from premises/operations; E&O covers economic/financial harm from a professional's mistake, even where no bodily injury occurs. Worked example: a consultant's flawed financial model causes a client a $500,000 economic loss with no bodily injury or property damage — the CGL does not respond, but E&O does.
Claims-Made Structure and Specialty Forms
Most E&O is written claims-made with a retroactive date, basic and supplemental ERPs (tails), and frequently defense-within-limits. Knowing the named forms helps:
| Profession | Common form name |
|---|---|
| Physicians, hospitals | Medical malpractice |
| Lawyers, accountants | Lawyers / Accountants E&O |
| Insurance agents | Insurance agents E&O |
| Architects/engineers | Design professionals E&O |
| Directors/officers | D&O (a specialized management-liability E&O) |
Many E&O forms require the insured's consent to settle (a hammer clause may reduce coverage if the insured refuses a recommended settlement). Trap: intentional or dishonest acts are excluded; E&O covers negligent professional errors, not deliberate fraud.
An insurer can settle a malpractice claim for $150,000, but the insured physician refuses to consent and the case proceeds to a $500,000 verdict. The policy contains a standard consent-to-settle (hammer) clause. What is the insurer most likely obligated to pay toward the verdict?
A consultant's E&O policy has a $1,000,000 limit on a defense-within-limits (eroding) basis. The insurer spends $300,000 defending a claim and then agrees to a $800,000 settlement. How much does the insurer pay toward the settlement?
