Find a Pensions & Retirement Plans Expert →Overview
A pensions and retirement plan expert decides whether the people running a plan did their job with the care ERISA requires: how they selected and monitored investments and vendors, what the plan paid, and whether the process would satisfy a prudent person familiar with such matters. Most cases are class actions over 401(k) fees and fund choices, along with disputes over plan administration and employer stock. This page covers plan governance and administration. Retail investment advice belongs to an investment management expert, pension funding math to an actuary, and individual health benefits to a health insurance expert.
ERISA's definition is functional. A person is a fiduciary to the extent they exercise discretionary control over plan management or assets, give investment advice for a fee, or have discretionary responsibility in administration 1. An employer can wear two hats, since a design decision may differ from an administrative one. So the first job is mapping who did what: the committee, the recordkeeper, the consultant and the investment manager. The plan document, committee charter and service agreements show the assignment, and the minutes show what happened.
The duty of prudence asks for the care, skill, prudence and diligence that a prudent man acting in a like capacity and familiar with such matters would use, and the plan must diversify to minimize the risk of large losses unless clearly not prudent 2. Hughes v. Northwestern (2022) ties the inquiry to context and to an ongoing duty to watch plan investments and drop the imprudent ones, while telling courts to respect the range of reasonable judgments a fiduciary can make 3. A fiduciary who breaches is personally liable to make good losses to the plan and to restore profits 4.
So a report tests the process. Did the committee meet regularly, review fund performance against a stated benchmark and watch fees? Did it obtain competing bids for recordkeeping? Did it use the cheapest share class available? Did it follow its investment policy statement? What did the consultant say, and did anyone read it? A bad result does not prove a bad process, and a good result does not cure a missing one, so the expert keeps those questions apart.
Comparators are the current fight. Anderson v. Intel, argued at the Supreme Court on October 6, 2026, asks whether a plaintiff must name a similar fund as a "meaningful benchmark" to get past the pleadings 8. Whatever the result, an expert needs to explain why a comparison fund or fee is truly similar in strategy, risk and service.
Fee claims often run through the prohibited transaction rules. Section 1106 bars a fiduciary from causing the plan to engage in listed transactions with a party in interest, including the furnishing of services 5. In Cunningham v. Cornell (2025), the Supreme Court held that the Section 1108 exemptions are affirmative defenses, so defendant fiduciaries bear the burden of pleading and proving them 6. That moves the fight to evidence sooner: was the arrangement necessary, and was no more than reasonable compensation paid?
Vendor disclosure supplies the record. The service provider regulation at 29 CFR 2550.408b-2 requires covered providers to disclose services and direct and indirect compensation to the responsible plan fiduciary 7. The expert reads those disclosures, annual plan filings, recordkeeping contracts and revenue sharing records, then works out what the plan really paid per participant and what comparable plans paid for comparable service. Reasonable compensation is a market question, so plan size and service scope matter.
Advice to participants raises a separate question. Who counts as an investment advice fiduciary has changed over time, and the expert should confirm the rule in force on the date of the advice and recommendation.
No license exists for plan fiduciaries or committee members. Look for someone who has served as a plan fiduciary or independent fiduciary, advised retirement plan committees, or run retirement services at a recordkeeper or consultant, in plans of similar size. Fee experts need market data and a clear method. A defined benefit funding dispute calls for an actuary, and investment performance measurement may call for a finance specialist. Whether a duty was breached is the ultimate legal question, so the expert should stay on prudent practice and what the record shows.
Under ERISA, a fiduciary who breaches its duties is personally liable to make good to the plan any losses resulting from the breach and to restore any profits made through use of plan assets.

FAQ
Look for service as a plan fiduciary, or years advising plan committees or running retirement services at a recordkeeper or consultant, in plans of similar size. No license exists for fiduciaries. Pension funding disputes need an actuary.
Not by itself. ERISA focuses on the process, including monitoring, and Hughes says courts must give due regard to the range of reasonable judgments a fiduciary may make. Performance can still be evidence that a fund should have been reviewed or removed.
The Supreme Court held that a plaintiff need not plead that the statutory exemptions do not apply to a prohibited transaction claim. The defendant raises those. The focus can then move sooner to evidence on what was paid and whether it was reasonable.
By what the plan paid against the services received, compared with similar plans. An expert uses 408b-2 disclosures, annual filings and contracts, and needs to show that comparisons are truly alike in size and service.
The definition is functional. A person is a fiduciary to the extent they exercise discretionary control over the plan or its assets, render investment advice for a fee, or hold discretionary responsibility in administration. A single person can be a fiduciary for one act and not for another.
In general, retirement plan expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, industry certifications, regulatory knowledge, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
