Providers: Aon and Counterpart. - Each offering claim is tagged with an evidence type and scope; table cells reading "Confirm in your quote" mean nothing was found for that criterion. - Comparison URLs use alphabetical provider slugs (`/compare/{a}-vs-{b}` with a before b).

[3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://yourcounterpart.com/products/fid "Fiduciary Liability Insurance") ## What Is Aon? Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

Counterpart describes a broker-focused platform for small businesses and lists management and professional liability programs. Buyers should compare the named profession, carrier, state, policy wording and any package component on the actual quote. [4](https://yourcounterpart.com/ "Counterpart | Agentic Insurance™") [5](https://yourcounterpart.com/about "About Counterpart") [Counterpart profile](https://spot.insure/insurance-providers/counterpart) ## What Is Fiduciary Liability Insurance? Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed.

Aon describes fiduciary placement or advice through its Professional Services Practice for law, accounting, and consulting firms. Buyers should identify the intermediary chain and issuing insurer in either proposal, especially when a wholesale broker participates in Counterpart’s route. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://yourcounterpart.com/products/fid "Fiduciary Liability Insurance") ### Coverage Terms and Service Counterpart’s page addresses employee-benefit-plan administration and ERISA exposures and includes illustrative limit examples. Aon’s page lists fiduciary among its practice lines but does not identify plan exposures or limits. Illustrative figures are not a quote, so a buyer needs a policy proposal to compare covered duties, insured plans, retentions, and whether the limit is shared with other management-liability coverage. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://yourcounterpart.com/products/fid "Fiduciary Liability Insurance") ## What to Confirm in Fiduciary Liability Insurance Quotes - Ask Counterpart which broker and carrier will issue the policy and replace examples with quoted terms. Ask Aon for its proposed carrier, covered plan types, and limits.
