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. 12,13,14,15
Key Differences in Professional Liability (E&O) Insurance
Named CNA programs and WTW brokerage work
CNA identifies Epack 3, EPS Plus, miscellaneous professional liability and Technology E&O, with dedicated claims and risk-control support for those professional-liability lines. WTW’s reviewed material describes professional-liability solutions within FINEX and errors-and-omissions for residential real-estate stakeholders, rather than a specific standard policy. If you need a defined CNA product, ask for its form; with WTW, clarify which market and wording the broker is seeking for your risk. 4 10
What happens between quote and issued policy
WTW’s terms say an insurer quote is not confirmation: after you order binding, WTW seeks a formal insurer commitment, typically a binder, and reviews issued documents against negotiated terms. CNA’s claims describe its own programs and support but do not explain that intermediary workflow. The practical comparison is product specificity versus a broker’s placement and document-checking process. Ask WTW who the proposed insurer is and what remains before binding; ask CNA for the declarations and final policy form. 4 11
