## Coterie Insurance vs Harper Professional Liability (E&O) Insurance 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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [1](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 Are the Key Differences Between Coterie Insurance and Harper 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. [3](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. [1](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..)

When comparing Coterie Insurance and Harper, weigh the support difference if you want help interpreting the policy before you bind it.

### 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. [3](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. [1](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. [4](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. [1](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 Should You Confirm in Coterie Insurance and Harper Professional Liability (E&O) Insurance Quotes?

- Ask Harper to walk through the specific exclusions it reviewed for your policy, not just the limit. [3](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. [1](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. [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [1](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. [1](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")

[3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") (Evidence: Company-reported; scope: Professional liability page's four coverage tiles; the E&O page adds that claims often surface a year or more after the work was delivered. The issued policy and its exclusions control actual scope..) |
| 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. [1](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. [3](https://www.harperinsure.com/coverages/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: Professional liability page introduction and 'Why Harper' section..)<br><br>Harper markets the identical policy under two catalogue entries, "Professional Liability" and "Errors and Omissions"; the E&O page states it is the same policy, just named what a given industry calls it. [4](https://www.harperinsure.com/coverages/errors-and-omissions "Errors and Omissions Insurance") [5](https://www.harperinsure.com/coverages "What We Cover") (Evidence: Company-reported; scope: Coverage directory listing plus the E&O page's own description; a naming convention Harper states about itself, not a distinction between two products..) |
