## What Is WTW?

## 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. [13](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [14](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [15](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [16](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

### Specialist exposure analysis

Marsh says its E&O practice brings attorneys, economists and actuaries together with coverage specialists to assess exposure; its industry list includes finance, accounting, law, architecture, media, technology and health care. WTW's record places professional liability within FINEX and names residential real estate as one E&O segment. If your work has a complex contract or regulatory profile, ask Marsh which specialists will review it and ask WTW which FINEX team applies to your sector. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [10](https://www.wtwco.com/en-us/industries/residential "Residential | WTW")

### Coverage scope and wording check

Marsh says many professional-liability policies cover privacy violations and computer-security breaches as well as defense costs for alleged errors or negligence. WTW describes reviewing policy wording against negotiated insurer terms. If you expect a claim could involve client advice and a data incident, ask Marsh whether both triggers are in the offered form and ask WTW to point out how the proposed form treats them. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [12](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")

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

- Ask Marsh whether privacy and computer-security claims are included in your E&O form or require separate cyber cover, and which specialists review your industry. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

- Ask WTW to identify the professional-services definition, cyber-related wording and exclusions in the policy it will review. [12](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")

| Risk Services | Marsh says it employs attorneys, economists and actuaries alongside coverage specialists to assess a client's professional liability exposure from multiple angles, given the complexity of these risks. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") (Evidence: Company-reported; scope: Marsh professional liability page..) | WTW's North American terms describe reviewing binders, policies, and endorsements against the terms negotiated with the insurer. [12](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Broker document-review process under the cited terms, when WTW handles this line's placement. It does not certify that a policy covers a claim or replace the issued wording..) |
| How to Apply | Confirm in your quote. | WTW's North American terms say an insurer quote is not confirmation of coverage; if the client orders binding, WTW seeks a formal insurer commitment, typically a binder. [12](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") (Evidence: Company-reported; scope: Applies to placements governed by the cited North American Corporate Risk & Broking terms. It does not establish a self-service quote route or promise coverage availability for this line..) |
