OPINION
This is an interpleader action in which Willie Lee Tinsley appeals the decision of the U.S. District Court for the Eastern District of Michigan granting summary judgment to third-party defendant-appel-lee Beulah Calloway and awarding the benefits of Edward B. Williams’s ERISA-covered life insurance plan to Calloway. For the reasons set out below, we REVERSE and REMAND for a trial on the merits.
I. BACKGROUND
Edward B. Williams, who died on December 18, 1996, had initially designated his niece, Willie Lee Tinsley, as the beneficiary of the life insurance plan that he maintained under the General Motors Life Insurance and Disability Program. Several days before his death, however, Williams executed a new “Designation of Beneficiary” form, naming his neighbor, Beulah Cаlloway, instead. Calloway had apparently cared for Williams while he was ill and resided with him for a period of time.
Both Calloway and Tinsley attempted to claim benefits from the General Motors plan. Subsequently, Tinsley filed suit agаinst General Motors and its insurer, Metropolitan Life, in the U.S. District-Court for the Middle District of Alabama, the state in which Tinsley fives, claiming that she was lawfully entitled to the insurance proceeds and that Williams was acting under undue influence from Calloway when he changed the beneficiary of his plan. After the case was transferred to the U.S. District Court for the Eastern District of Michigan, GM and Metropolitan Life filed a third-party complaint for inter-pleader, which brought third-pаrty defendant Beulah Calloway into the action. On May 10, 1999, the district court granted summary judgment in favor of GM and Metropolitan Life based on their deposit of $14,077.80 with the Clerk of Court, representing the entire amount of benefits due under the fife insurаnce program, plus interest.
*703 Calloway then moved for summary judgment, claiming that there was no genuine issue of material fact concerning the appropriate beneficiary under the GM Plan and that no competent evidence supported Tinsley’s claim of undue influence. Applying state law, the district court granted Calloway’s motion and dismissed Tinsley’s complaint. The district court found that Tinsley had the burden of proving that Williams’s decision to change thе beneficiary of his life insurance plan was affected by undue influence exerted by Calloway, and that Tinsley had failed to carry that burden. On appeal, Tinsley, acting pro se, argues that the district court erred in its determinatiоn of her undue influence claim. Moreover, she suggests, as she did in the district court, that Williams’s signature on the second beneficiary designation form may have been forged.
II. ANALYSIS
A. Summary Judgment Standard
This court reviews de novo the district court’s grant of summary judgment.
See Equitable Life Assurance Soc’y v. Poe,
Moreover, although the evidence produced by the nonmoving party need not necessarily be “in a form that would be admissible at trial,”
Celotex Corp. v. Catrett,
B. ERISA Preemption
Although the district court, like the parties, looked to Michigan state law in its discussion of Tinsley’s claims, we believe that federal law governs this case, because it involves an employee welfare benefit plan that is governed by the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. § 1001
et seq.
ERISA prеempts any state law that relates to — that is, that “has a connection with or reference to” — an ERISA-covered plan.
Shaw v. Delta Air Lines, Inc.,
*704
In this case, Tinsley’s claim is for payment of ERISA benefits, and it concerns the legitimacy of the beneficiary designation contained in the plan documents. The Supreme Court has explained that a suit by a beneficiary to recover benefits from an ERISA-covered plan “falls directly under § 502(a)(1)(B) of ERISA, [29 U.S.C. § 1132(a)(1)(B),] which provides an exclusive federal cause of action for resolution of such disputes.”
Metropolitan Life Ins. Co. v. Taylor,
C. Undue Influence
Since Tinsley’s claim for thе benefits of Williams’s life insurance plan is preempted by ERISA, this court must “look to either the statutory language or, finding no answer there, to federal common law which, if not clear, may draw guidance from analogous state law.”
McMillan,
Having reviewed the case law regarding undue influence in the various states that comprise this circuit, we can extract some shared general principles to guide our federal-common-law analysis of Tinsley’s undue influence claim. First, undue influence is generally defined as influence that is “sufficient to overpower volition, destroy free agency, and impel the grantor to act against the grantor’s inclination and free will.”
McPeak v. McPeak,
As our summary of the law suggests, the inquiry into the exercise of undue influencе is a highly fact-intensive one.
See
25 Am.Jur.2d
Duress and Undue Influence
§ 31 (1996). Moreover, as a result of the subtle and often covert ways in which undue influence may be exercised, it must often be proven by means of circumstantial evidence.
See, e.g., Rich v. Quinn,
D. Forgery
Tinsley also suggests that Williams’s signature on the beneficiary designation *706 form may have been forged. The district court did not address this contention below. We therefore remand for the district court to consider Tinsley’s forgery claim.
III. CONCLUSION
For the foregoing reasons, we REVERSE the district court’s grant of summary judgment and REMAND for further proceedings consistent with this opinion.
Notes
. Several cases in this circuit have read ERISA's mandate that fiduciaries administer plans "in accordance with the documents and instruments governing the plan,” 29 U.S.C. § 1104(a)(1)(D), to mean that courts need not look beyond the beneficiary designation form to determine the appropriate beneficiary.
