How Does Professional Errors and Omissions (E&O) Insurance Compare With Related Coverage?
Technology Errors and Omissions
Confirm whether the quote schedules professional services under professional errors and omissions (E&O) coverage, or uses a separate technology errors and omissions form for technology products or services. 4,2,5Medical Malpractice
Medical malpractice is a specialized professional-liability product for health care; do not treat a general professional E&O quote as a substitute for it. 5,2,4Business Owner’s Policies
Do not assume a business owner’s policy includes professional liability; check the proposed coverage and whether you need a separate policy. 2,6How Do You Compare Professional Errors and Omissions (E&O) Insurance Coverage and Costs?
Claims-Made Timing
Ask whether the quote is claims-made, when a claim must be made and reported, and whether an occurrence form is available instead. 2,1,4When replacing claims-made coverage, compare the retroactive date and reporting terms with your current policy. Earlier work may need to remain covered, and known circumstances must be disclosed. A new start date alone doesn't establish continuity for advice or services you delivered in the past. 4,1
If you change insurers or stop buying claims-made coverage, ask about an extended reporting period for later claims arising from earlier work. 2,4,1| Timing question | What to ask |
|---|---|
| Claims-made or occurrence | When must the claim be made and reported, and is an occurrence form available instead? |
| Retroactive date | Does prior work count, and have you disclosed known circumstances that could become claims? |
| Changing insurers or stopping coverage | Is an extended reporting period available for later claims that arise from earlier work? |
Defense, Limits and Scheduled Services
Check the insurer’s duty to defend, whether defense expenses reduce the available limit, and any consent-to-settle terms. 4,1,2 Compare the each-claim limit, the aggregate limit, and the deductible or retention. 4,2 Confirm the named businesses and people insured and the professional services the quote actually schedules. 4,1Exclusions
Ask how the quote treats bodily injury, property damage, dishonest acts, intellectual-property claims and failure to protect confidential information. 4,2What Do You Need for Professional Errors and Omissions (E&O) Insurance Quotes?
Services and Contracts
Prepare a description of the professional services you sell, who performs them, and the clients or contracts that require proof of insurance. 4,1,3Claims History and Current Terms
Have information on prior claims, incidents and known circumstances that could become claims ready for the discussion. 4,1 Bring current professional-liability terms, the retroactive date and any existing extended-reporting or tail arrangement. 4,1| Prepare | Ask the broker |
|---|---|
| Services and people performing them | Which services and insured names will the policy schedule? |
| Prior claims or circumstances | What records and known issues should you disclose? |
| Current policy and retroactive date | How will coverage continue if you change insurers or end a claims-made policy? |
