## 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. [8](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") [9](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [10](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Coverage Scope and Plan Details

Heffernan Insurance Brokers presents fiduciary liability to general business clients and to family offices, trust companies, trustees, financial advisers, private-equity firms, and foundations. Its family-office practice describes a risk assessment that maps structures, assets, and exposures, then supports coverage-gap and claims work. Marsh McLennan Agency names fiduciary liability in its executive-liability suite and invites adviser contact, without describing a parallel risk assessment on the cited page. A complex trust or investment structure makes the service scope worth confirming before comparing premiums. [4](https://www.heffins.com/family-office/ "Family Office") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Placement and Buyer Questions

Heffernan Insurance Brokers lists fiduciary as an arranged line but does not describe its policy insuring agreement or exclusions on the family-office page. Marsh McLennan Agency’s overview likewise does not provide plan-specific grants. Both quotes should therefore be checked against the particular plans, fiduciaries, and advisory roles involved. [4](https://www.heffins.com/family-office/ "Family Office") [7](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 Heffernan Insurance Brokers what its risk assessment includes for trustees and advisers and request the carrier’s fiduciary wording and exclusions. [4](https://www.heffins.com/family-office/ "Family Office")
- Ask Marsh McLennan Agency to identify the covered plans and fiduciaries and explain any risk-review or claim-navigation services. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## Offering Details

| Criteria | Heffernan Fiduciary Liability Insurance | Marsh McLennan Agency fiduciary (official overview) |
| --- | --- | --- |
| Role in This Line | Heffernan places fiduciary liability coverage within its general corporate/executive-protection lineup and again within a dedicated family-office and financial-institution practice. It shops and places the coverage with insurers rather than underwriting it. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Business Insurance and Family Office page listings; no dedicated fiduciary-liability product page was found..) | Marsh McLennan Agency describes arranging fiduciary for the audience stated on the cited product page. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: fiduciary marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Issuing Insurer | The reviewed pages do not name the insurer or insurers that issue fiduciary liability policies Heffernan places for either business clients or family offices. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Not publicly disclosed; scope: Business Insurance and Family Office pages as read on 2026-09-23..) | Confirm in your quote. |
| Who It’s For | Heffernan offers fiduciary liability to two named segments: general business clients through its business-insurance brokerage, and family offices, trust companies, trustees, financial advisors, private equity firms, foundations, and other financial institutions through its family-office practice. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Direct practice-page listings; no minimum size or asset-under-management threshold was published for the coverage specifically..) | Organizations seeking executive liability solutions; source does not define plan-specific eligibility. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: fiduciary marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Coverage Features | On the family-office page, fiduciary liability insurance is listed alongside directors and officers, professional liability, employment practices liability, trustee liability, and other management-liability-adjacent lines as coverage the practice can arrange, without describing the policy's insuring agreement or exclusions. [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23..) | The cited product page describes fiduciary liability as a named product in the executive and professional liability suite; the overview does not state plan-specific grants. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: fiduciary marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Limits and Retentions | Neither page publishes a fiduciary-liability limit, retention, or premium range. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Not found in reviewed sources; scope: Business Insurance and Family Office pages as read on 2026-09-23..) | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| Risk Services | Heffernan's family-office practice describes a Risk Management Assessment: itemizing a client's structures, assets, and exposures; crafting insurance and risk-management strategies to close coverage gaps; and helping navigate claims, for its fiduciary and financial-institution client base. [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23; a company-described service, not a measured outcome..) | Confirm in your quote. |
| How to Apply | The family-office practice's fiduciary-liability coverage is reached through a named Private Client Group specialist contact rather than a self-service online quote flow. [4](https://www.heffins.com/family-office/ "Family Office") (Evidence: Company-reported; scope: Family Office page as read on 2026-09-23; the general business-insurance page's fiduciary listing routes through Heffernan's general Contact Us form instead..) | 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. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: fiduciary marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience.
