## 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. [10](https://www.dol.gov/sites/dolgov/files/ebsa/employers-and-advisers/guidance/field-assistance-bulletins/erisa-fidelity-bonding-requirements.pdf "Field Assistance Bulletin No. 2008-04: Guidance Regarding ERISA Fidelity Bonding Requirements") [11](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [12](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Placement and Plan Fit

Marsh’s FINPRO practice places fiduciary insurance for retirement-plan sponsors and fiduciaries; Aon describes fiduciary placement or advice for law, accounting, and consulting firms. Both operate as brokers, so the comparison turns on which specialist team and insurer will serve the plan. Marsh’s description is more specifically centered on retirement plans, while Aon frames the line within its professional-services practice. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability")

### Published Coverage and Services

Marsh says typical policies cover defense, damages, judgments, and settlements for breach of duty or negligence in plan administration, but not contractual liability guaranteeing benefits. Its team also reviews fiduciary controls, builds programs, and advocates on claims. Aon describes risk advice but gives no fiduciary grants or claims service detail. The contractual-liability limit matters when a plan disputes benefits owed. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Marsh how its form treats contractual benefit obligations and what claims advocacy entails. Ask Aon for comparable wording, carrier, limit advice, and claims support. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability")

## Offering Details

| Criteria | Aon Fiduciary Liability brokerage and risk-advisory offering | Marsh Fiduciary Liability Insurance |
| --- | --- | --- |
| Role in This Line | Aon presents Fiduciary Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) | Marsh's FINPRO (financial and professional) practice places fiduciary liability insurance for retirement plan sponsors and fiduciaries; MMA also lists fiduciary coverage within its executive and professional liability practice. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") (Evidence: Company-reported; scope: Marsh fiduciary liability page and MMA executive and professional liability page..) |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) | The reviewed pages do not name a specific fiduciary liability insurer. Marsh describes its own role as advising on limit assessment and carrier selection, implying the issuing insurer depends on the placement. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") (Evidence: Not publicly disclosed; scope: Fiduciary liability page as read on 2026-09-23..) |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | Marsh says a fiduciary liability policy typically insures the sponsor organization, the benefit plans it operates, and plan fiduciaries who are directors, officers or employees of the plan sponsor. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") (Evidence: Company-reported; scope: Fiduciary liability page, Who is covered? FAQ..) |
| Coverage Features | Aon lists Fiduciary coverage within the professional-services practice’s property-and-casualty coverages. The page does not describe covered fiduciary acts, plans, exclusions or policy terms. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) | Marsh says a fiduciary liability policy typically covers defense costs, damages, judgments and settlements from a fiduciary's breach of duty or from negligence, errors or omissions in administering a benefit plan, but does not cover contractual liability, so it cannot guarantee a plan's obligation to pay benefits due. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") (Evidence: Company-reported; scope: Fiduciary liability page FAQs; illustrative policy description, not a specific policy form..) |
| Limits and Retentions | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) | Confirm in your quote. |
| Risk Services | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) | Marsh says its FINPRO practice helps clients identify red flags in fiduciary controls, builds fiduciary liability programs from limit assessment to carrier selection, and provides claims advocacy to help resolve claims from the outset. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") (Evidence: Company-reported; scope: Fiduciary liability page, Why Marsh section..) |
| Claims Support | Confirm in your quote. | Marsh describes its claims advocates as helping clients resolve fiduciary liability claims from the onset, without publishing outcome statistics for this line. [8](https://www.marsh.com/en/services/financial-professional-liability/expertise/fiduciary.html "Fiduciary liability") (Evidence: Company-reported; scope: Fiduciary liability page, Why Marsh section..) |
