Professional Liability
If your business gives advice, designs something, or provides a service that could cause financial harm if it goes wrong, your general liability policy will not cover that. Professional liability (also called Errors and Omissions, or E&O) is what does.
What it is.
GL covers physical things: bodily injury and property damage. Professional liability covers PROFESSIONAL acts: alleged errors, omissions, negligent advice, missed deadlines, design defects, professional negligence claims. Two completely different exposures and two completely different policies.
Almost every service-based business needs E&O. Accountants, lawyers, financial advisors, IT consultants, real estate agents, architects, engineers, marketing agencies, designers, insurance agents (yes, we carry our own), real estate brokers, technology consultants. Increasingly, contractors with design-build elements need it too.
Below is what professional liability actually covers, the claims-made structure that makes timing important, and how the retroactive date determines whether a policy responds at all.
Service businesses where a customer could allege financial harm from advice, design, or work you performed. If a contract you sign asks for E&O, you're in this category.
What it covers.
Each policy is a stack of named coverages. Required parts are mandated by state law. Recommended parts are what we put on most policies. Optional parts depend on your situation.
Defense Costs
Legal fees to defend against alleged errors, omissions, or negligent professional acts. Usually included WITHIN the policy limit (defense erodes the limit) but can be written outside the limit on better policies. Always confirm.
Settlements and Judgments
Payouts to clients alleging professional negligence. Most claims are settled rather than litigated; the policy responds to either path.
Claims-Made Coverage
Standard structure for E&O. The policy responds to claims FIRST MADE during the policy period, regardless of when the alleged act occurred (subject to retroactive date). Different from occurrence-based GL. Continuity matters.
Personal and Advertising Injury
Often included or available as an extension. Defamation, copyright infringement, trade-name violations from your business communications.
Cyber Liability (limited)
Some E&O policies include limited cyber coverage (privacy breach, network security). Not a substitute for a standalone cyber policy if your data exposure is meaningful.
Disciplinary Defense
Defense costs for state board complaints, professional licensing actions, or regulatory inquiries. Available on many professional E&O policies aimed at licensed professions.
Subpoena Coverage
Covers the cost of responding to subpoenas in matters where you are not a defendant. Useful for accountants, lawyers, and consultants who get drawn into client disputes.
Tail Coverage (Extended Reporting Period)
Allows you to report claims AFTER the policy ends, for acts that occurred during the policy period. Critical when retiring or closing a business. Usually 1, 3, or 5 years available; some carriers offer unlimited.
Prior Acts / Retroactive Date
The earliest date your policy will cover. New policies often start with TODAY's date as retro, leaving past work uninsured. Continuous prior-acts coverage when switching carriers is critical to protect older work.
When it kicks in.
Real situations we see in the agency. The point is to show how each layer of coverage maps to actual life, not to scare you.
CPA misses a tax deadline
Client files late and incurs $40,000 in penalties and interest. Client sues for the penalties. E&O pays defense costs and any settlement up to the limit. GL would NOT have covered this.
IT consultant deletes the wrong database
Restoring from backup costs the client $80,000 in lost productivity and recovery costs. E&O responds to the negligent professional act. GL would only cover the physical damage to the server, not the data loss.
Real estate agent fails to disclose a property defect
Buyer discovers a foundation issue post-close that the seller had told the agent about. Agent didn't relay it. Buyer sues. E&O pays defense and any settlement.
Architect's design causes water intrusion
Building leaks 2 years after completion. Investigation traces to a design error. Claims-made policy responds if the policy is in force when the claim is reported, AND the act falls after the retroactive date.
Marketing agency uses copyrighted image
Stock photo used without proper licensing. Photographer sends a $25,000 demand. Personal and Advertising Injury extension on the E&O pays defense and settlement.
Key terms.
Plain-English definitions. The vocabulary insurance carriers assume you already know.
- 01Claims-Made
- Policy responds to claims FIRST MADE during the policy period, regardless of when the act occurred (subject to retro date). Standard for E&O.
- 02Occurrence
- Policy responds to acts that OCCUR during the policy period, regardless of when the claim is filed. Standard for GL. Almost never available for E&O.
- 03Retroactive Date
- The earliest date of acts the policy will cover. Continuous prior-acts coverage (matching the original retro date when you switch carriers) is critical to protect older work.
- 04Tail Coverage / ERP
- Extended Reporting Period. Allows claims to be reported after the policy ends, for acts during the policy period. Essential at retirement or business sale.
- 05Defense Within Limits vs Outside Limits
- Within: defense costs reduce the policy limit. Outside: defense is paid in addition to the limit. Outside is materially better but more expensive. Worth the upgrade for many professions.
- 06Hammer Clause
- Some policies require your consent to settle. If you refuse a settlement and a higher judgment results, the carrier limits its payout to what the original settlement would have been. Confirm before binding.
Common questions.
Questions clients ask before they get on the phone with AJ. If yours isn’t here, just call.
GL covers physical things (slip-and-fall, knocking over a vase). E&O covers professional acts (bad advice, missed deadlines, design errors). They cover completely different exposures. Most professional service contracts require BOTH.
