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. 9,10,11,12
Key Differences in Professional Liability (E&O) Insurance
Prior acts, tail and contractor terms
HUB says its E&O policies are typically claims-made, can include prior acts back to a retroactive date, may offer tail coverage, and can extend to independent contractors and temporary staff doing work for the business. MMA’s source names E&O and separate A&E and lawyers lines. A business changing brokers should compare the proposed retroactive date and insured-person language in the actual policy rather than assume continuity from the product names. 5 8
Line category and policy-specific terms
HUB describes structure options for its E&O placement, with specific limits and retroactive dates set by the quote and declarations. MMA’s source names general E&O and specialist professional products. For the same operation, ask both teams to identify the form, each-claim and aggregate limits, reporting period and whether temporary staff or contractors are insured. 5 8
