What Are the Key Differences Between Counterpart and Marsh McLennan Agency Professional Liability (E&O) Insurance?

Specialty Lines Named

Marsh McLennan Agency’s product overview names E&O, architects-and-engineers and lawyers professional lines, and says those specialties are not one form. Counterpart names separate programs for A&E/contractors, lawyers, allied healthcare and miscellaneous professionals. A firm should match its actual work to the relevant specialty instead of treating the shared E&O label as evidence of equivalent forms. [6] [3] [2] [5] [9]

Comparing the Proposed Form

The reviewed Marsh McLennan Agency overview identifies the named product lines but does not set universal terms; Counterpart’s pages include examples for selected professions, which are illustrative. For a buyer, the useful comparison is the proposed professional-services definition and the actual insurer and schedule, not the catalogue title. Request the wording for the precise specialty from either placement. [3] [2] [5] [9]

What Should You Confirm in Counterpart and Marsh McLennan Agency Professional Liability (E&O) Insurance Quotes?

  • Marsh McLennan Agency: identify whether the proposal is its A&E, lawyers or another E&O line. Counterpart: confirm the selected class, insurer, and quote-specific limits and exclusions. [3] [5] [9]

Both catalogues identify separate professional specialties: Marsh McLennan Agency names A&E and lawyers lines, while Counterpart also lists allied-health and miscellaneous programs.
