Key Differences in Professional Liability (E&O) Insurance
Specialty Placement and Document Review
WTW’s FY2024 report lists professional-liability solutions within FINEX, and its residential practice includes E&O for residential real-estate stakeholders. For engagements governed by its North American Corporate Risk & Broking terms, WTW normally acts as intermediary and reviews binders, policies and endorsements against negotiated terms. Nationwide describes E&O for professional-service claims and directs buyers to agents, but its overview does not describe the same brokerage document-review process. A buyer should check which WTW terms govern and who reviews the final policy documents. 9 8 10 4
Binding Confirmation
WTW’s North American terms state that an insurer quote does not confirm coverage and that, after the client orders binding, WTW seeks formal insurer commitment, typically a binder. Nationwide’s overview invites an agent contact or quote request but does not describe the binding sequence. For either route, ask what written document confirms coverage and when it takes effect. 10 4
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask WTW whether the engagement is governed by North American CRB terms, who reviews the final policy and what constitutes binding confirmation. 10
- Ask Nationwide’s agent which insurer issues the form and what written confirmation is needed before coverage starts. 4
- Confirm whether the E&O quote is for a residential real-estate stakeholder or another professional class, and request matching limits and endorsements. 8 4
