Coterie Insurance vs Harper: How Do They Compare for Professional Liability (E&O) Insurance?

When a client contract demands E&O, Harper says its broker specialist places matching cover and issues the certificate the same day. Coterie Insurance sells through agents and brokers only, with limits between $25,000 and $1,000,000.

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. ^3,¹

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 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. ¹Company-reported. 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 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

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 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

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
Ask an agent or broker whether your profession carries a listed exclusion in Coterie's base form beyond the general ones. ¹
Get the issuing insurer from both; neither reviewed page names one for this line. ⁴ ¹
If your business operates in DC, IL, MA, MT, ND or VA, confirm Coterie's MPL is actually available there before comparing pricing. ¹
