ERISA Death Benefits: Reasonable Proof-of-Loss Requirements Support Denial of Prejudgment Interest

1. Introduction

This appeal concerns the financial consequences of delayed payment of accidental-death benefits when an insured person disappears at sea and official investigations do not formally establish his death. Although Life Insurance Company of North America (LINA) ultimately paid $200,000, the estate sought prejudgment interest and attorney’s fees under the Employee Retirement Income Security Act (ERISA).

Robert C. Williamson, Jr., acting as curator of the estate of Larry D. Henning, brought the claim. LINA issued the accidental-death policy to American Maritime Officers Plans (AMOP), the group policyholder. Ana Maria Lunar, who claimed to be Henning’s widow, was also a defendant in the underlying litigation. Her asserted entitlement complicated the claim, but this appeal centered on LINA’s handling of proof of death and the estate’s entitlement to additional monetary relief.

The principal questions were whether the policy conferred discretion on LINA, whether requiring formal proof of death was a permissible exercise of that discretion, and whether the eventual benefits payment required an accompanying award of interest or fees.

2. Factual and Procedural Background

• Disappearance in 2013: Henning and three others departed Charleston, South Carolina, aboard a fishing vessel. The Coast Guard later found debris approximately 22 nautical miles east of Florida. Searches did not locate Henning.
• Official reports: The Florida Fish and Wildlife Conservation Commission listed Henning as “missing.” The Coast Guard declined to issue a Letter of Presumed Death because it lacked authority to do so, instead reporting that he remained missing.
• Estate administration and competing claim: Williamson became curator in August 2014 and supplied AMOP with investigative materials. Lunar subsequently asserted a claim as Henning’s widow. AMOP rejected her marriage certificate, which was later determined to be forged.
• Submission to LINA: Approximately two years later, the estate sought available life-insurance benefits. AMOP forwarded a completed claim form and supporting documentation to LINA.
• Request for further proof: LINA requested a finalized death certificate “or other formal document indicating the death of Larry Henning.” After two unanswered follow-up efforts, it closed the claim without denying it and explained that the estate could reopen it by providing the requested information.
• Litigation: The estate sued in 2018. LINA ultimately paid $200,000, but the estate continued to pursue interest and attorney’s fees.
• District court rulings: The district court denied the estate’s summary-judgment motion and fee request, then granted LINA summary judgment on prejudgment interest. It concluded that LINA permissibly required additional proof and had not breached the policy.

The appellate opinion does not specify the eventual payment date or identify the precise documentation that finally satisfied LINA. Its holding therefore should not be treated as establishing a generally permissible waiting period for missing-person claims.

3. Summary of the Opinion

The Sixth Circuit affirmed the district court’s judgment.

1. The policy granted discretion. Its requirement that proof of loss be “satisfactory to Us” gave LINA discretion to determine whether the submitted evidence was sufficient.
2. Deferential review applied to LINA’s proof-of-loss decision. The district court properly examined that decision under the arbitrary-and-capricious standard.
3. The district court did not apply that standard directly to interest. Instead, its conclusion that LINA had permissibly deferred payment informed the separate equitable decision whether interest was warranted.
4. The benefits were not wrongfully withheld. Given the unresolved proof of death and the policy’s allocation of evidentiary responsibility to the claimant, the district court reasonably found that payment was not due earlier.
5. The conditional fee request failed. Because the estate did not prevail on prejudgment interest, the court declined its request to remand for reconsideration of attorney’s fees.

4. Analysis: Precedents Cited

A. Standards of appellate review

• Fortney & Weygandt, Inc. v. Am. Mfrs. Mut. Ins. Co., 595 F.3d 308, 310 (6th Cir. 2010). The court cited this decision for de novo review of summary judgment. That framework required independent appellate examination of whether judgment could properly be entered without a trial; it did not itself determine how much discretion LINA possessed under the policy.

• Hunt v. Sycamore Cmty. Sch. Dist. Bd. of Educ., 542 F.3d 529, 534 (6th Cir. 2008). This case supplied additional authority for the same summary-judgment standard. Together, these two decisions established the procedural lens through which the appeal reached the court.

• Schumacher v. AK Steel Corp., 711 F.3d 675, 681, 686 (6th Cir. 2013). This precedent played two roles. First, it established abuse-of-discretion review of prejudgment-interest decisions, including errors of fact, legal standards, or judgment. Second, it required consideration of case-specific factors and competing interests to reach an equitable result. It therefore supported both the appellate standard and the individualized nature of the interest inquiry.

B. Policy language conferring administrative discretion

• Shelby Cnty. Health Care Corp. v. Majestic Star Casino, LLC, 581 F.3d 355, 365, 376 (6th Cir. 2009). The court relied on this case for the rule that an express grant of administrative discretion triggers arbitrary-and-capricious review of benefit decisions. Equally importantly, it cited the case for the principle that ERISA prejudgment interest is compensatory, not punitive, and does not require wrongdoing. Thus, the opinion did not make insurer misconduct a prerequisite to interest.

• Frazier v. Life Ins. Co. of N. Am., 725 F.3d 560, 566 (6th Cir. 2013). This decision explained that no particular “magic words” are necessary to confer discretion, but the policy must contain a clear grant. It directed attention to the substance of the policy language rather than a required drafting formula.

• Perez v. Aetna Life Ins. Co., 150 F.3d 550, 556 (6th Cir. 1998). This was the central authority on policy interpretation. It recognized that a requirement for proof satisfactory to the insurer or administrator can confer discretion. Applying that principle, the panel treated LINA’s “satisfactory to Us” language as sufficient. The estate acknowledged that existing precedent supported the district court’s approach but asked the panel to reconsider Perez; the panel held that it could not do so.

C. The binding force of earlier published decisions

• Zurich Am. Ins. Grp. v. Duncan ex rel. Duncan, 889 F.3d 293, 301 (6th Cir. 2018). The court quoted this decision for the rule that a later panel cannot overrule an earlier published panel decision. This prevented reconsideration of Perez within the ordinary three-judge appeal.

• United States v. Lee, 793 F.3d 680, 684 (6th Cir. 2015). This decision reinforced the same prior-panel constraint. Its relevance was institutional rather than specific to insurance law.

• Bennett v. MIS Corp., 607 F.3d 1076, 1095 (6th Cir. 2010). This case provided further support for adherence to existing circuit precedent. Along with Sixth Circuit Rule 32.1(b), these authorities explained why the estate’s disagreement with Perez could not alter the governing standard in this appeal.

D. Interest, evidentiary responsibility, and reasonable benefit decisions

• Ford v. Uniroyal Pension Plan, 154 F.3d 613, 616, 620 (6th Cir. 1998). The court used this precedent to establish that prejudgment interest is governed by equitable discretion. It also relied on Ford when concluding that benefits paid when due did not justify interest. The relevant question was not simply how much time had elapsed, but whether payment had been improperly deferred.

• Wells v. U.S. Steel, 76 F.3d 731, 737 (6th Cir. 1996). This decision supplied the general proposition that pension beneficiaries have a right to interest on benefits wrongly withheld. The panel treated wrongful withholding as the critical premise missing from the estate’s argument, rather than treating eventual recovery of benefits as automatically sufficient.

• Williamson v. Life Ins. Co. of N. Am., No. 3:18-CV-100-CRS, 2025 WL 283226, at *6 (W.D. Ky. Jan. 23, 2025). This was the district court’s own decision in the litigation, not an independent appellate precedent. The Sixth Circuit endorsed its reasoning that the policy placed responsibility for satisfactory proof on the claimant and did not require LINA to undertake the additional investigation demanded by the estate.

• Miller v. Metro. Life Ins. Co., 925 F.2d 979, 984 (6th Cir. 1991). The district court cited this case in support of the claimant’s evidentiary burden, and the appellate opinion incorporated that reasoning. Its role was to support the allocation of responsibility under the policy—not to establish that administrators never have investigative obligations under ERISA.

• Spangler v. Lockheed Martin Energy Sys., Inc., 313 F.3d 356, 361 (6th Cir. 2002). This decision provided the substantive test for deferential review: an eligibility decision is not arbitrary and capricious when rational in light of the plan’s provisions. It supported the conclusion that requiring formal death documentation was reasonable under this policy and these circumstances.

E. Attorney’s fees

• Hardt v. Reliance Standard Life Ins. Co., 560 U.S. 242, 255 (2010). The Supreme Court’s requirement of “some degree of success on the merits” supplied the threshold for an ERISA fee award. Here, the estate conditioned its requested fee remand on success concerning interest. Because that challenge failed, the panel rejected the requested remand. The opinion did not separately analyze whether the eventual $200,000 payment could independently satisfy the threshold in a differently framed fee claim.

5. Analysis: Legal Reasoning

A. Three distinct standards must not be conflated

The estate’s principal objection depended on an asserted misuse of arbitrary-and-capricious review. The panel answered by distinguishing three inquiries:

The district court used deferential review to assess LINA’s conduct, not as the direct standard governing the interest award. That antecedent assessment nevertheless mattered: a permissible decision to await adequate proof supported the conclusion that no compensable delay had occurred.

B. The policy made satisfactory proof a condition of payment

The operative provision required written or electronic proof of loss “satisfactory to Us.” Under Perez, that language delegated judgment to LINA concerning evidentiary sufficiency.

This did not give LINA unrestricted power to withhold benefits. Its decision still had to be rational under the policy. But the court was not free simply to substitute its preferred assessment of the evidence for the administrator’s reasonable assessment.

C. Evidence of a probable death was not necessarily satisfactory formal proof

The estate emphasized the shipwreck, unsuccessful searches, and investigative reports. Those circumstances strongly supported its position that Henning had died. Nevertheless, the reports continued to describe him as missing, and the Coast Guard expressly lacked authority to issue the requested presumption-of-death document.

Against that background, the court upheld LINA’s request for formal documentation. Importantly, LINA’s original request allowed either a finalized death certificate or another formal document indicating death. The decision therefore does not establish that a conventional death certificate is invariably indispensable.

The unanswered follow-up requests and closure without denial also contextualized LINA’s conduct. The claim remained capable of reopening when the estate supplied the requested proof.

D. The policy did not shift the proof-gathering burden to LINA

The estate argued that LINA should have investigated further or approved the claim on the existing record. The court rejected both propositions because this policy placed the burden of supplying satisfactory proof on the claimant.

The narrowness of that conclusion matters. The opinion does not announce a universal exemption from investigative responsibilities. It holds that the additional investigation demanded here was not required by this policy in these circumstances.

E. Interest compensates for lost use of money that should have been paid

The court expressly recognized that wrongdoing is unnecessary for prejudgment interest. An insurer may owe compensatory interest even without bad faith or punitive-worthy conduct.

Nevertheless, compensation requires a relevant deprivation. The district court concluded that the estate had received benefits when entitled to them, rather than after an improper withholding period. The Sixth Circuit found no abuse of discretion in declining interest on that basis.

Thus, the court did not equate innocence with immunity from interest. It distinguished the absence of misconduct from the separate absence of benefits owed earlier. Nor did it establish an automatic statutory interest rate or accrual date; those questions were unnecessary after entitlement to interest failed.

6. Potential Impact and Limits

For claimants and estate representatives

The decision underscores the importance of promptly responding to documentation requests. Evidence that makes death highly probable may not satisfy a policy’s formal proof requirements, particularly where official reports still classify the insured as missing. Representatives should identify what alternative formal documentation the insurer will accept rather than assume that investigative reports alone complete the claim.

For insurers and administrators

Clear discretionary language, documented requests, reasonable opportunities to supplement the record, and an explanation of how to reopen a claim can support a defensible decision to defer payment. The opinion does not, however, authorize impossible evidentiary demands or indefinite delay. A requirement must remain rational under the particular policy and record.

For future ERISA litigation

The decision illustrates how a dispute over documentation can determine a later interest claim even after the principal benefits have been paid. Litigants must address when payment became due, not merely the length of the interval between loss and payment.

Its reach is limited by the discretionary policy language, unresolved formal proof of death, unanswered requests, and the estate’s conditional fee argument. Different plan terms or a record showing sufficient proof at an earlier date could support a different outcome. Its nonpublication designation further counsels against treating it as a broad new rule governing every missing-person insurance claim.

7. Complex Concepts Simplified

Curator

A court-appointed representative who administers or protects an estate. Williamson acted for Henning’s estate, not personally.

Proof of loss

Documentation establishing that an insured event occurred and that the policy’s payment conditions are met.

Arbitrary-and-capricious review

A deferential test asking whether the administrator’s decision was rational under the plan, rather than whether the court would have made the same decision independently.

De novo review

Independent appellate examination without deference to the district court’s legal conclusion.

Abuse of discretion

Review for an improper exercise of judicial judgment, including reliance on incorrect law, erroneous facts, or a clear error of judgment.

Prejudgment interest

Interest compensating a claimant for being deprived of money before judgment. Under the authorities applied here, it is not punishment.

En banc reconsideration

Reconsideration by the court sitting en banc rather than an ordinary three-judge panel. The panel could not itself overrule the published precedent controlling the policy-language issue.

Some degree of success on the merits

The threshold substantive success required before an ERISA attorney’s-fee award may be considered; satisfying that threshold does not automatically require an award.

8. Conclusion

The Sixth Circuit affirmed because LINA reasonably exercised policy-based discretion to require satisfactory formal proof of death, and the estate did not establish that benefits should have been paid earlier. That conclusion supported denial of prejudgment interest and defeated the estate’s conditional request for renewed consideration of attorney’s fees.

The opinion’s broader significance lies in separating three matters that are easily confused: discretion over proof, equitable compensation for delayed payment, and eligibility for fees. Eventual payment does not itself establish wrongful delay, while the absence of insurer wrongdoing does not itself foreclose interest. The decisive inquiry remains whether, under the governing policy and evidence, payment was due sooner.
