Idaho: Beneficiary Disputes and Interpleader Under Idaho Law

Community property comes first

Two things can be true at once in Idaho: a person can be the named beneficiary and still have to share. “Idaho is a community property state. Idaho Code § 32-903.”¹ When a married insured names someone other than the spouse, the spouse may claim a community interest in the proceeds.

How much depends on classification. “The Idaho Supreme Court has adopted the risk payment theory to classify such policies as either separate or community property.”² Under that approach, the source of the money used for the premiums matters, so bank records and payroll deductions often decide these cases.

In Darney, an estranged wife claimed half of a policy naming the insured’s adult daughter. The court granted partial summary judgment but left a fact issue about where the premium funds came from.

Divorce revocation and the timing question

Idaho adopted the uniform-code revocation section. As quoted in a District of Idaho opinion, § 15-2-804(b) begins: “Except as provided by the express terms of a governing instrument, a court order or a contract relating to the division of the marital estate made between the divorced individuals before or after the marriage, divorce or annulment, a divorce or annulment of a marriage: (1) Revokes any revocable: (i) Disposition or appointment of property made by a divorced individual to his or her former spouse in a governing instrument”.³

Barnett shows the problem with older policies. The policy was bought in 1984 and named the insured’s then-wife. They divorced in 1999, he remarried in 2006, and he died in 2020 while living in New Mexico. The widow asked the court to certify to the Idaho Supreme Court whether § 15-2-804 revokes a designation when the death came after the statute’s enactment. The court declined: “certifying the question seems like the most expeditious way to prolong the case, not resolve it.”⁴ It expressly left the statute’s interpretation for a later, fully briefed motion.⁵

Changing a beneficiary: substantial compliance

Idaho follows the general rule that “[w]here the policy, as a matter of contract, specifies the method of changing beneficiaries, [] a change of beneficiary can be accomplished only in the manner pointed out in the policy.” A change can still take effect without complete compliance if the insured “substantially compli[ed],” which, as the District of Idaho described the Idaho Supreme Court’s test, means proof by a preponderance of the evidence that the insured intended the change and attempted it “to the best of his abilities.”⁶ On intent, the court looks to “(1) the completeness to which the forms were filled out, (2) testimony of witnesses which established the insured intended to make a change of beneficiary, and (3) the length of time between completing and signing the change form and forwarding it to the insurance company.”⁷

In Anderson, the insured’s girlfriend filled in the first page of a change form naming herself. The insured had the signature page notarized weeks later without the first page, and the insurer received both pages in April 2019, with the insured’s name, policy number and date missing. The insurer mailed a letter asking him to complete the form; he died five weeks later without doing so. After a bench trial, the court found that any intent to name the girlfriend “was abandoned prior to his death,” and that the mailbox rule raised a presumption he received the insurer’s letter. Evidence that he was disorganized with his mail did not rebut it.⁸ Because his former wife was still the named beneficiary, the divorce-revocation statute meant the proceeds went to his estate.⁹

Slayer rule

Idaho Code § 15-2-803 is Idaho’s homicide section.¹⁰ Editors confirmed its heading on the official site but did not rely on its text for this page.

Fees for the insurer

In Barnett, the court found that the insurer had acted in good faith in interpleading the $640,000 death benefit, noting that the good-faith requirement is “not an onerous requirement” and “is necessarily low”.¹¹ It still denied the insurer’s fee request for now because the request lacked the detail Local Rule 54.2(b) requires, while allowing a renewed request at final judgment.¹²
