Fiduciary Liability Insurance

February 11, 2026

Why It Matters

Fiduciary liability insurance protects employers and plan fiduciaries from claims alleging mismanagement of employee benefit plans. Understanding fiduciary liability coverage helps clarify how it differs from directors & officers (D&O) insurance and why ERISA exposure requires specialized protection.

Understanding Fiduciary Liability Insurance: A Practical Guide

Employers that sponsor retirement or health benefit plans take on fiduciary responsibilities under federal law, particularly under the Employee Retirement Income Security Act (ERISA). These responsibilities create personal and corporate liability exposure for those managing the plans.

Fiduciary liability insurance exists to protect against claims alleging breaches of fiduciary duty.

This guide explains what fiduciary liability insurance covers, how it works, and why it is distinct from other management liability policies.


What Is Fiduciary Liability Insurance?

Fiduciary liability insurance is a management liability policy that protects plan sponsors, trustees, and fiduciaries from claims alleging:

  • Breach of fiduciary duty
  • Errors in plan administration
  • Improper investment decisions
  • Failure to follow plan documents
  • Mismanagement of employee benefit plans

Coverage typically includes legal defense costs and settlements.


What Problem Does Fiduciary Liability Insurance Solve?

Fiduciary liability insurance addresses risks such as:

  • Lawsuits alleging excessive retirement plan fees
  • Claims of imprudent investment selection
  • Allegations of failure to diversify plan assets
  • Administrative errors in enrollment or eligibility
  • Failure to comply with ERISA requirements

Without coverage, fiduciaries may face personal financial exposure.


Who Is a Fiduciary?

Under ERISA, a fiduciary is anyone who:

  • Exercises discretionary authority over plan management
  • Controls plan assets
  • Provides investment advice for a fee
  • Has discretionary authority in plan administration

This can include:

  • Company executives
  • HR managers
  • Plan committees
  • Trustees

Fiduciary status is based on function, not job title.


How Fiduciary Liability Insurance Works

At a high level:

  1. An employer sponsors an employee benefit plan.
  2. A claim is filed alleging breach of fiduciary duty.
  3. The insurer provides or reimburses legal defense.
  4. Covered settlements or judgments are paid, subject to policy limits.

Policies are typically written on a claims-made basis.


Key Coverage Components

Most fiduciary liability policies include:

  • Defense Costs
  • Settlements and Judgments
  • Administrative Error Coverage
  • Voluntary Compliance Program Coverage (sometimes)
  • Coverage for Individual Fiduciaries

Coverage may apply to both the company and individual fiduciaries.


Fiduciary Liability vs D&O Insurance

Important distinction:

FeatureFiduciary LiabilityD&O Insurance
Covers ERISA ClaimsYesTypically No
Covers Plan MismanagementYesNo
Covers Corporate GovernanceNoYes
Protects Individual FiduciariesYesYes (for corporate acts)

D&O policies generally exclude ERISA fiduciary claims.


What Fiduciary Liability Insurance Typically Does Not Cover

Common exclusions include:

  • Intentional fraud or criminal acts
  • Personal profit or illegal remuneration
  • Benefits owed under the plan itself
  • Bodily injury or property damage
  • Certain prior known claims

Fiduciary insurance covers management errors—not plan performance guarantees.


What Affects the Cost of Fiduciary Liability Insurance?

Premiums are influenced by:

  • Size of retirement plan assets
  • Number of plan participants
  • Type of plans offered (401(k), ESOP, health plan)
  • Claims history
  • Investment structure
  • Governance processes

Larger plans with significant assets face higher exposure.


Growing Litigation Trends

Recent trends include:

  • Excessive fee litigation
  • Target-date fund performance disputes
  • ESG-related investment scrutiny
  • Class-action lawsuits

Retirement plan litigation has increased significantly in recent years.


Risk Management Considerations

Insurers may evaluate:

  • Investment committee structure
  • Documentation practices
  • Independent fiduciary oversight
  • Regular fee benchmarking
  • Compliance processes

Strong governance reduces exposure and premium cost.


Smart Questions to Ask an Agent

When evaluating fiduciary liability insurance, consider asking:

  • Does this policy cover both the company and individuals?
  • Are defense costs inside or outside policy limits?
  • Does coverage apply to healthcare plans as well?
  • Is voluntary correction program coverage included?
  • What exclusions apply to investment-related claims?

Understanding ERISA exposure is critical.


When Fiduciary Liability Insurance Makes Sense — and When It Might Not

Fiduciary liability makes sense if:

  • You sponsor a 401(k), pension, or health plan
  • You have plan assets under management
  • You appoint fiduciaries or committees
  • You want protection from ERISA litigation

It may be less necessary if:

  • No employee benefit plans are sponsored
  • Plan administration is fully outsourced (though fiduciary responsibility may still exist)

For most employers offering retirement plans, fiduciary coverage is prudent.

Key Takeaway

Because ERISA imposes strict standards and litigation risk is rising, this coverage plays a critical role in protecting both corporate and personal assets.
