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

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [7](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [8](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [9](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [10](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## What Are the Key Differences Between Marsh McLennan Agency and Zurich U.S. Professional Liability (E&O) Insurance?

### Program Structure and Named Professional Lines

Zurich describes Pro Plus as a modular suite that brings coverages together in one policy and says admitted E&O is available in most states. Marsh McLennan Agency instead identifies E&O alongside separate architects-and-engineers and lawyers professional lines. If you want to place E&O with other coverages, ask Zurich which modules would appear together; if your work is in a named profession, ask MMA which specialist line applies. Neither overview establishes the endorsements or limits in an individual quote. [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") [6](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

### Documented Claim Scope and Service

Zurich describes E&O claims involving negligence, mistakes, or failure to deliver promised services, including defense costs, court fees, settlements, and judgments. It also identifies claims specialists who review claims under policy terms with legal counsel coordination. MMA’s overview names its professional lines but gives no comparable claims-handling steps. For a buyer, that means Zurich’s published material is more specific about its E&O claim process; ask MMA who handles a claim and what legal coordination is included before weighing service. [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") [6](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")
