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

Coterie publishes tiered E&O limits and tail terms while Chubb's Pro ERM discloses only defense-cost treatment.

## Research Scope and Use

Use this comparison to evaluate Chubb and Coterie Insurance for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Coterie publishes each-claim limit options from $25,000 to $1,000,000 with a built-in extended reporting period, while Chubb's Pro ERM covers 100% of defense costs worldwide without publishing a separate liability limit. [8](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.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## 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. [9](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [10](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [11](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [12](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

### What Each Publishes on Limits

Coterie publishes each-claim limit options from $25,000 to $1,000,000, with the aggregate set at two to three times the each-claim limit. [8](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") Chubb instead says Pro ERM covers 100% of defense costs for covered claims worldwide, without publishing a separate liability limit figure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Extending Coverage After the Policy Ends

Coterie's base MPL policy includes a 60-day extended reporting period, with optional purchased extensions of one to six years and up to six years of prior-acts coverage. [8](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") Chubb's reviewed Pro ERM page does not describe an extended reporting period or retroactive-date structure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Where Coverage Is Actually Available

Coterie says MPL is currently unavailable in the District of Columbia, Illinois, Massachusetts, Montana, North Dakota and Virginia. [8](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") Chubb's reviewed page names target clients and product features for Pro ERM but does not mention state-level availability restrictions. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

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

- Ask Coterie to confirm coverage is actually available in your state before relying on its published limits. [8](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")
- Confirm Chubb's actual liability limit for Pro ERM, since the reviewed page names defense-cost treatment but not a limit figure. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Ask Chubb whether tail or extended-reporting coverage is available for Pro ERM, since its page does not describe the option. [3](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Get the issuing insurer for Coterie's MPL; its brochure names only a policy form code, not the carrier. [8](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")

[8](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. [8](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..) |
