6 Fiduciary-Breach Mistakes That Cause Claimants to Miss Broader ERISA Claims

Many ERISA disputes start the same way: a benefits claim gets denied, the appeal feels stacked against the participant, and the conversation quickly narrows to whether the denial itself was “right” or “wrong.” But in some cases, the larger issue is not just the denial. It may be how the plan was administered, whether conflicts affected decision-making, whether disclosures were misleading, or whether fiduciaries failed to monitor the plan at all.
That distinction matters. ERISA imposes fiduciary duties of loyalty and prudence on people who exercise discretionary authority over plan management or administration, and federal law provides separate avenues for relief when those duties are breached, beyond a simple claim for benefits under the plan terms. The U.S. Department of Labor describes fiduciaries as people with discretionary control over plan management, plan assets, or plan administration, and notes that courts may take action against fiduciaries who breach those duties. The Department also explains that ERISA’s fiduciary rules are designed to protect participants and beneficiaries. The Supreme Court has likewise recognized ongoing fiduciary duties, including a continuing duty to monitor plan investments in retirement-plan cases. See Tibble v. Edison International and Hughes v. Northwestern University.
In this post you’ll learn six common mistakes that can cause claimants to overlook broader ERISA fiduciary-breach theories, why those mistakes happen, and what facts often signal that a case may involve more than a one-time denial. If you want broader background on how plan mismanagement, conflicts, and administrative failures fit into ERISA’s fiduciary framework, it may help to start with this overview of how fiduciary duty issues can arise in plan administration.

Why A Denial-Only View Can Miss The Bigger ERISA Picture

ERISA benefit disputes often get framed as contract-style disagreements: the participant asks for benefits, the plan says no, and the fight becomes whether the plan terms support payment. That is one type of ERISA case. But it is not the only type.
Under ERISA, fiduciaries generally are expected to act solely in the interest of participants and beneficiaries and with the care, skill, prudence, and diligence of a prudent person familiar with such matters. The statute’s civil-enforcement scheme also allows different kinds of claims, including claims for benefits and claims seeking relief for fiduciary misconduct. You can see the basic enforcement structure in 29 U.S.C. § 1132, and the fiduciary-duty provisions in 29 U.S.C. § 1104 and 29 U.S.C. § 1109.
That means a denied claim may sometimes be evidence of a broader administration problem, not just an isolated bad call. For example:
  • a plan representative may have made misleading statements about coverage or eligibility;
  • the plan’s procedures may have been inconsistent with ERISA claims regulations;
  • the same structural conflict may have affected repeated decisions;
  • disclosures may have been incomplete, confusing, or inaccurate;
  • decision-makers may have ignored information they were required to consider;
  • a retirement plan committee may have failed to monitor fees, service providers, or investment options over time.
The Supreme Court’s decision in Varity Corp. v. Howe is a well-known example showing that misleading participants while acting in a fiduciary capacity can support fiduciary-breach relief under ERISA. In the retirement-plan context, LaRue v. DeWolff, Boberg & Associates recognized that fiduciary-breach claims can reach losses affecting an individual participant’s defined-contribution account, rather than only losses to an entire plan.
With that backdrop, here are six mistakes that often cause claimants to miss the broader claim.

1. Treating Every ERISA Problem As Only A Benefit Denial

The first mistake is assuming that if benefits were denied, the only possible case is a wrongful-denial case.
That framing is common because the denial letter is usually the first formal event in the dispute. It feels concrete. It names a plan provision. It gives an appeal deadline. It often becomes the center of gravity.
But a denial letter may be just the visible endpoint of a longer fiduciary problem.
For health, disability, and other welfare plans, the Department of Labor’s claims-procedure regulation sets minimum standards for how claims are processed, including requirements for notices and appeals. The agency describes 29 C.F.R. § 2560.503-1 as establishing minimum procedural requirements for ERISA-covered benefit claims. If the issue is not merely “the plan interpreted the terms differently,” but instead “the process was skewed, incomplete, or administered through conflicted or misleading practices,” the case may point beyond denial alone.
This often comes up when a claimant says things like:
  • “They never really evaluated the evidence.”
  • “The explanation changed every time we asked questions.”
  • “The plan told me one thing before I enrolled and another after I filed.”
  • “They kept asking for more records without addressing the records already submitted.”
  • “This keeps happening to many people in the same plan.”
Those are not automatic fiduciary-breach claims. But they are often clues that a lawyer may want to look past the denial itself and examine administration, discretion, and plan conduct more broadly.

2. Ignoring Who Was Acting As A Fiduciary And When

A second mistake is assuming that every employer, claims handler, consultant, or administrator is automatically acting as an ERISA fiduciary at all times.
ERISA fiduciary status is functional. In general terms, the question is whether the person or entity exercised discretionary authority or control over plan management, plan assets, or plan administration. The Department of Labor’s fiduciary-responsibilities guidance explains this functional approach.
That cuts both ways.
Sometimes claimants overlook a viable fiduciary issue because they focus only on the insurer or only on the employer’s name on the paperwork, instead of asking who actually exercised discretion. In other cases, they assume every bad act is fiduciary conduct when some acts may be settlor, business, or ministerial decisions instead.
Why does this matter? Because broader ERISA claims often turn on identifying:
  • who had discretionary authority;
  • who communicated with participants about benefits;
  • who made or influenced the final decision;
  • who controlled plan assets, fees, or investment options;
  • who had the duty to monitor another fiduciary or service provider.
The Supreme Court in Varity focused closely on whether the company was acting in a fiduciary capacity when it communicated with employees. In retirement-plan litigation, Tibble emphasized that fiduciaries may have an ongoing duty to monitor investments after initial selection.
If the wrong actors are identified too early, an otherwise broader case can get boxed into a narrower theory.

3. Overlooking Misrepresentations And Disclosure Failures

A third mistake is focusing only on the final denial and not on what participants were told before the dispute began.
ERISA plans are heavily disclosure-driven. Participants are entitled to important plan documents, including a summary plan description, and the Department of Labor explains that the SPD is one of the main ways participants learn how the plan works, what benefits exist, and how claims are filed. See DOL plan information guidance and the agency’s reporting and disclosure guide.
That matters because some fiduciary-breach issues arise before a denial ever happens:
  • enrollment materials may describe benefits in a materially incomplete way;
  • the SPD may not match the actual administrative practice;
  • representatives may give inaccurate guidance about eligibility, deadlines, or coverage;
  • plan communications may minimize exclusions, offsets, or discretionary standards;
  • participants may rely on plan statements that later turn out to be misleading.
The classic Supreme Court example is Varity, where deliberate deception directed at participants supported fiduciary-breach relief. Not every inaccurate statement rises to that level. But where the dispute involves fiduciary communications, participant reliance, and harm tied to misleading information, limiting the case to “my claim was denied” can leave out a major part of the story.
This is one reason experienced ERISA counsel often want to review more than the denial letter. Enrollment materials, SPDs, summary of material modifications, committee records, emails, call logs, and written explanations can all matter in understanding whether the issue is administrative misconduct rather than only an adverse benefits determination.

4. Assuming Procedural Violations Are Technicalities Instead Of Evidence

A fourth mistake is treating claims-handling defects as minor paperwork problems rather than possible evidence of a broader fiduciary or administrative breakdown.
The Department of Labor’s claims-procedure rules require adverse determinations to include specific information, such as the reasons for the denial, the plan provisions relied on, and information about appeal procedures. The DOL’s disclosure guide and claims-procedure materials outline these requirements.
When a plan repeatedly fails to provide a coherent explanation, fails to identify the governing plan language, fails to describe what information is missing, or uses appeal procedures in a confusing or inconsistent way, that may be more than sloppiness. It can suggest:
  • the decision was not reasoned;
  • the process may have been outcome-driven;
  • the participant lacked a fair opportunity to respond;
  • the plan may be handling many claims through the same flawed system.
This issue comes up often in disability and health-benefit disputes, but the broader concept applies elsewhere too: procedure can reveal substance. A badly handled claim file may reflect a larger failure of oversight, training, monitoring, or conflicted administration.
Some claimants see these defects and assume they are too technical to matter. In practice, procedure often becomes the roadmap to a wider theory of fiduciary misconduct.

5. Missing The Difference Between Individual Relief And Plan-Level Relief

A fifth mistake is not recognizing that some ERISA fiduciary-breach theories involve harm to the plan, to a participant account, or to multiple participants, not just the claimant’s unpaid benefit.
That distinction can be especially important in retirement-plan cases. In LaRue, the Supreme Court explained that ERISA fiduciary-breach claims under § 502(a)(2) can address losses to an individual participant’s account in a defined-contribution plan. In Tibble and Hughes, the Court addressed fiduciary duties related to investment monitoring and excessive-fee allegations in participant-directed plans.
Why do claimants miss this? Because many people understandably look only at their own immediate loss:
  • denied LTD payments;
  • denied medical treatment;
  • reduced pension benefits;
  • depleted 401(k) account value.
But the legal theory may turn on broader conduct such as:
  • imprudent investment selection or retention;
  • failure to monitor service providers or recordkeeping costs;
  • conflicts affecting plan-wide administration;
  • systemic claim practices affecting multiple participants;
  • misuse or imprudent handling of plan assets.
If a claimant and counsel look only for a benefits payment, they may not fully evaluate whether the facts also suggest plan-level fiduciary misconduct, account-level losses, or injunctive and equitable relief.

6. Waiting Too Long To Investigate The Full Administrative Record And Plan Documents

The sixth mistake is delay.
ERISA cases are document-heavy. Many of the facts that help distinguish a pure denial case from a broader fiduciary-breach case live in plan materials, internal procedures, committee structures, fee arrangements, communications, and the administrative record. The Department of Labor explains that participants are entitled to important plan documents, including SPDs, and that these materials describe rights, benefits, and claim procedures. See Plan Information and How to Obtain Employee Benefit Plan Documents.
Delay can narrow options in several ways:
  • appeal deadlines may pass before the right arguments are framed;
  • relevant communications may be harder to locate;
  • the claimant may focus too narrowly in the internal appeal;
  • broader patterns involving other participants may go unnoticed;
  • limitations issues may become harder to evaluate.
This does not mean every ERISA claimant has a broader fiduciary case. It means time often affects how completely the case can be understood.
That is especially true where the facts involve repeated plan-administration issues, inconsistent disclosures, fee structures, committee oversight, or conflicts between what the plan said and what it did. A lawyer with relevant ERISA litigation experience may be able to compare those facts against known fiduciary theories and identify whether the case appears limited to benefits or potentially reaches further.

What Facts Often Suggest A Broader Fiduciary-Breach Theory

A few patterns tend to raise that possibility:
  • the plan gave inconsistent explanations over time;
  • communications to participants appear misleading or incomplete;
  • claim reviewers ignored categories of evidence without explanation;
  • the same issue appears to affect multiple participants;
  • plan fees, investment options, or service-provider arrangements seem poorly monitored;
  • the SPD or enrollment materials do not line up with actual administration;
  • there are signs of structural conflicts or self-interested decision-making;
  • the decision-making process looks less like a neutral review and more like a closed loop.
None of those facts automatically establish liability. But they often justify looking beyond a single denial letter and asking a broader question: Was this really just a denied claim, or was it part of a larger fiduciary failure?

Why Attorney Fit Matters In These Cases

ERISA litigation can be unusually specialized. A lawyer handling these matters may need to identify the correct defendants, analyze fiduciary status, understand the claims-procedure regulations, separate settlor conduct from fiduciary conduct, and evaluate which ERISA remedies may fit the facts.
That is one reason many claimants lose time when they search only for a general employee-benefits lawyer or only for someone who handles denials in a narrow sense. In some situations, the more useful question is whether the attorney has documented experience with highly similar ERISA fiduciary issues, such as misrepresentation, monitoring failures, excessive fees, administrative conflicts, or broader plan-governance disputes based on court records and case similarity.

Final Takeaway

A denied ERISA claim is not always just a denied ERISA claim. Sometimes it is. Sometimes it also reflects misleading disclosures, conflicted administration, procedural irregularities, plan-wide monitoring failures, or other fiduciary problems that call for a broader legal analysis.
The six mistakes above often have one thing in common: they cause claimants to accept the plan’s framing of the dispute too early. When that happens, important theories may never get investigated.
If your situation involves more than a simple “yes or no” benefits decision, you may want to consider whether the facts point toward fiduciary conduct, plan administration failures, or broader ERISA claims beyond denial alone.
