## 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. [9](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") [10](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [11](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Coverage Details and Plan Fit

Beazley publishes fiduciary limits up to $20 million, with an optional additional defense limit, and identifies statutory sublimits including $250,000 for several ERISA and tax-code claims and $1 million for HIPAA claims. Marsh McLennan Agency’s reviewed page lists fiduciary liability in its executive and professional suite but does not publish fiduciary limits or plan-specific grants. Buyers comparing limit figures should keep the overall limit separate from the statutory sublimits and verify which apply to their plan. [5](https://www.beazley.com/en-us/products/executive-risk-usa/fiduciary/ "Fiduciary") [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Placement and Buyer Questions

Beazley underwrites the policy and also lists BeazleySure risk-management content for policyholders; Marsh McLennan Agency describes arranging a placement through an adviser. Beazley’s page lists an ExecuGuard application rather than a fiduciary-only application. Ask Marsh McLennan Agency which carrier and program it would propose before comparing terms to Beazley’s stated structure. [5](https://www.beazley.com/en-us/products/executive-risk-usa/fiduciary/ "Fiduciary") [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Beazley how the $250,000 statutory sublimits and $1 million HIPAA sublimit apply within the quoted aggregate and whether additional defense limit is selected. [5](https://www.beazley.com/en-us/products/executive-risk-usa/fiduciary/ "Fiduciary")
- Ask Marsh McLennan Agency for the issuing insurer, total limit, statutory sublimits, and any plan-specific endorsements in the proposed wording. [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

| How to Apply | The Fiduciary page lists a downloadable ExecuGuard application as its Tools & Resources item, rather than a fiduciary-only application. [5](https://www.beazley.com/en-us/products/executive-risk-usa/fiduciary/ "Fiduciary") (Evidence: Company-reported; scope: Fiduciary product page Tools & Resources section as read on 2026-09-23..) | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement. The page does not establish a quote, bind, or coverage-effective timeline.

This is not a policy form or a universal eligibility statement..) |
| Claims Support | Beazley says fiduciary policyholders get pre-approved choice-of-counsel flexibility, but the reviewed page does not otherwise describe fiduciary-specific claims handling beyond that; general policy notice and claims-contact guidance is provided on Beazley's separate claims-notification page. [5](https://www.beazley.com/en-us/products/executive-risk-usa/fiduciary/ "Fiduciary") (Evidence: Company-reported; scope: Fiduciary product page as read on 2026-09-23; claims-handling quality is not independently assessed..) | Confirm in your quote. |
