# Coterie Insurance vs Harper Professional Liability (E&O) Insurance

It identifies differences and questions to confirm; it does not select a winner for a particular business.

Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Harper says a specialist reads a professional liability policy's exclusions line by line before a client buys. Coterie's MPL brochure instead lists its base-form exclusions directly, including bodily injury, fraud, and wrongful termination claims.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### An Exclusions Review Service Versus a Published Exclusions List

Harper says a specialist reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Coterie instead publishes its own base-form exclusions directly in its brochure:

Coterie's MPL base form excludes bodily injury or property damage claims, fraud or intentional wrongful acts, wrongful termination or discrimination claims, and claims based on contractual liability assumed beyond what would exist without the contract, among other listed exclusions. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure 'Professional Liability Policy Base Form Exclusions' list..)

### Same-Day Certificates Versus a Fixed Extended-Reporting Structure

Harper says that when a client contract requires E&O, it places coverage matching that requirement and issues the certificate the same day. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") Coterie's MPL includes a 60-day extended reporting period by default, with optional purchased extensions of 1 to 6 years and up to 6 years of prior-acts coverage. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers")

### The Same Coverage Under Two Names Versus Dozens of Named Professions

Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions," saying they're the same policy named differently by industry. [8](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") Coterie lists dozens of specific eligible professions for MPL instead, including accounting services, architects and engineers, bookkeeping, human resources consulting, interior design, and technology services/IT consulting. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask Harper to walk through the specific exclusions it reviewed for your policy, not just the limit. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance")
- Ask an agent or broker whether your profession carries a listed exclusion in Coterie's base form beyond the general ones. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers")
- Get the issuing insurer from both; neither reviewed page names one for this line. [8](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers")
- If your business operates in DC, IL, MA, MT, ND or VA, confirm Coterie's MPL is actually available there before comparing pricing. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers")

## Offering Details

| Criteria | Coterie Miscellaneous Professional Liability (MPL) | Harper Professional Liability Insurance |
| --- | --- | --- |
| Role in This Line | Coterie writes Miscellaneous Professional Liability (MPL) as a claims-made policy sold through agents and brokers to protect a small-business client against third-party claims for errors or omissions in their professional services. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure policy-overview paragraph..) | Harper places professional liability coverage as a broker, writing the policy around the applicant's actual services rather than underwriting it, and describes a specialist handling the placement.

| Who It’s For | Coterie lists dozens of eligible professions for MPL, including accounting services, architects and engineers, bookkeeping, human resources consulting, interior design, property management, real estate agents/brokers, and technology services/IT consulting, each with profession-specific exclusions in some cases (for example, barbers/beauticians exclude services like electrolysis and tattoo services). [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure 'Eligible Professions' and 'Eligible Professions (Continued)' lists..)<br><br>Coterie says MPL is available in most states but is currently unavailable in DC, IL, MA, MT, ND, and VA.

[7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and FAQ distinguishing it from general liability..) |
| Coverage Features | Coterie's MPL policy covers economic or financial (non-physical) damages arising from wrongful acts in professional services, such as faulty reports or verbal advice that cause a client financial loss; it is written on a claims-made basis covering incidents reported during the policy period or an extended reporting period, occurring after the policy's retroactive date. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure policy overview and 'Professional Liability Limits of Insurance' definitions..)<br><br>Coterie's MPL base form excludes bodily injury or property damage claims, fraud or intentional wrongful acts, wrongful termination or discrimination claims, and claims based on contractual liability assumed beyond what would exist without the contract, among other listed exclusions.

[4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure 'Available Limits' table and 'Extended Reporting Period'/'Retroactive Date' definitions..) | Not described in the reviewed sources. |
| Risk Services | Not described in the reviewed sources. | Harper says it reads a policy's exclusions line by line before a client buys, because two E&O policies with the same limit can respond very differently to the same claim. [7](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page 'We know this' section; a described review practice, not an independently verified outcome..) |
| How to Apply | MPL is distributed only through agents and brokers using Coterie's quoting platform; the reviewed brochure does not describe a direct-to-business application path. [4](https://8588529.fs1.hubspotusercontent-na1.net/hubfs/8588529/Current%20Appetite%20Content/Professional%20Liability%20Brochure_December2025.pdf "Miscellaneous Professional Liability (MPL) Policy Overview & Product Highlights for Agents and Brokers") (Evidence: Company-reported; scope: MPL brochure framing as 'for Agents and Brokers'..) | You request a quote online or by phone; if a client contract requires E&O, Harper says it places coverage matching that requirement and issues the certificate the same day.
