William Kennedy divorced his wife, Liv, in a decree that waived her interest in his retirement savings plan, but the account still held over $400,000 when he died five years later. He never got around to filing a new beneficiary form. The plan administrator paid the full account to Liv anyway, because her name was still on the form. His daughter fought it all the way to the Supreme Court, and lost.

That case, Kennedy v. Plan Administrator for DuPont Savings and Investment Plan, decided in 2009, is not a rare edge case. It is the rule. A divorce decree changes what a court says you are entitled to. It does not change what a retirement plan’s paperwork says.

The first 30 days after the decree

Within the first week, request a current beneficiary designation form from every institution that could pay out on your death: your employer’s 401(k) or pension administrator, every individual life insurance carrier, and every individual retirement account (IRA) custodian. Do not assume one update covers all of them. Each institution keeps its own separate form.

Within the first two weeks, file the new form with each institution and get written confirmation that it was received and processed, not just mailed. A form sitting in a drawer protects no one.

If your divorce decree specifically addresses a Qualified Domestic Relations Order (QDRO), a special court order that tells a retirement plan how to divide the account between spouses, understand that the QDRO is a different document from a beneficiary designation. A QDRO governs how the marital portion of the account is split during the divorce. It does not, on its own, name who receives the remaining balance if you die afterward. That still requires the separate beneficiary form.

Why the decree alone does not change anything

Employer-sponsored 401(k)s, pensions, and group life insurance policies are almost always governed by the Employee Retirement Income Security Act (ERISA), the 1974 federal law setting minimum standards for most employer benefit plans. ERISA requires plan administrators to pay strictly according to “the documents and instruments governing the plan,” under 29 U.S.C. Section 1104(a)(1)(D), and a separate provision, Section 1144(a), makes ERISA override conflicting state laws.

In Kennedy, the Supreme Court ruled that even a signed divorce-decree waiver did not change who the plan had to pay, because “ERISA provides no exception to the plan administrator’s duty to act in accordance with plan documents.” The plan’s own form controlled, full stop.

Many states have “revocation on divorce” statutes that automatically strip an ex-spouse’s beneficiary status on a life insurance policy the moment a divorce is finalized. These can work well for a policy you bought yourself, outside of any employer plan. But in Egelhoff v. Egelhoff, decided in 2001, the Supreme Court ruled that these state laws are preempted, meaning overridden, when the policy is part of an employer-sponsored ERISA plan. An employer group life insurance policy gets no automatic protection from your state’s revocation law.

What the law actually protects, and what it does not

Account type	Governed by ERISA?	Does divorce automatically change the beneficiary?	What actually changes it
Employer 401(k) or pension	Yes	No	A new beneficiary form filed with the plan administrator
Employer group life insurance	Yes	No, even in a “revocation on divorce” state	A new beneficiary form filed with the plan or insurer
Individually purchased life insurance	No	Sometimes, if your state has a revocation-on-divorce statute	Check your specific state law, then file a new form regardless
Individual retirement account (IRA)	No	No automatic federal rule; state law may apply	A new beneficiary form filed with the IRA custodian

What is actually at stake

The median retirement account balance among account-holding households was $86,900 in 2022, with a mean of $334,000, according to the Federal Reserve’s Survey of Consumer Finances. That is the range of what can go to an unintended beneficiary, in full, with no court able to reverse it after the fact, the way the Kennedy family learned when their case reached the Supreme Court and still failed.

Add a life insurance death benefit, often $250,000 or more on a standard employer group policy, and the exposure on an unchanged beneficiary form after divorce can run into six figures on a single form nobody thought to update.

The next 30 days

At day 7, confirm you have identified every account: every current employer’s retirement plan, every past employer’s retirement plan you have not rolled over, every life insurance policy, and every IRA. Old 401(k)s from a prior job are the ones people forget.

At day 14, confirm each new beneficiary form has been received and processed, not just submitted. Ask for a written confirmation number or a copy of the updated form on file.

At day 30, if a QDRO is also part of your divorce, confirm it has been “qualified,” meaning formally accepted, by the plan administrator, since an unqualified QDRO does not yet divide anything. This is a separate step from the beneficiary form, covered fully in the 90 days after a divorce decree when a retirement plan is split by QDRO. And if you are managing this alongside becoming a single parent, the first 30 days as a newly single parent after divorce covers the parallel deadlines running the same month.

Frequently asked questions

Does my divorce decree automatically remove my ex-spouse as my 401(k) beneficiary? No. The plan pays according to the beneficiary designation form on file, not the divorce decree. The Supreme Court confirmed this in Kennedy v. Plan Administrator for DuPont Savings and Investment Plan, 555 U.S. 285 (2009), even where the ex-spouse had signed a waiver in the decree itself.

My state has a law that removes an ex-spouse as a beneficiary automatically. Does that protect my 401(k)? No, if the account is an employer-sponsored plan governed by ERISA. In Egelhoff v. Egelhoff, 532 U.S. 141 (2001), the Supreme Court ruled that state revocation-on-divorce laws do not apply to ERISA plans. It may still apply to an individually purchased life insurance policy, depending on your state.

Is a QDRO the same thing as updating my beneficiary form? No. A Qualified Domestic Relations Order (QDRO) divides the marital portion of a retirement account during the divorce itself. It does not name who receives the remaining balance if you die later. That requires a separate beneficiary designation form filed with the plan.

Do IRA beneficiary rules work the same way as 401(k) rules? Not exactly. IRAs are not governed by ERISA, so a state’s revocation-on-divorce law may apply to one, depending on your state and custodian. Regardless, the custodian will default to the beneficiary on file until you submit a new form, so filing one is still the safest step.

What happens if I die before updating the beneficiary form? The plan or insurer pays the beneficiary named on the form on file at the time of death, regardless of what your divorce decree, will, or any other document says. This was the exact outcome in the Kennedy case, and there is no exception for proven intent after the fact.
