You spent months negotiating the divorce. You divided the house, split the bank accounts, argued over who gets the furniture. Your attorney filed the decree. It's done.

Except it isn't. Because sitting in a filing cabinet at your employer's HR department — or in an insurance company's database — is a form you signed years ago that still names your ex-spouse as the person who gets everything when you die.

Your will doesn't fix this. Your divorce decree doesn't fix this. And in most cases, your state's law doesn't fix it either.

The Override Problem

Here's the part that catches people off guard: beneficiary designations on retirement accounts, life insurance policies, and payable-on-death (POD) bank accounts operate outside your will. They are contract-level instructions that tell a financial institution exactly who to pay, and they supersede whatever your estate plan says.

Think of it as two separate tracks running in parallel. Track one is your will and trust — the documents your estate attorney drafted. Track two is a collection of beneficiary forms you filled out years ago at your job, your bank, and your insurance company. When you die, track two wins every time there's a conflict.

This isn't a technicality. It's the single most common post-divorce financial landmine in America. The assets governed by beneficiary designations — 401(k)s, IRAs, life insurance, annuities, POD accounts — often represent the majority of a person's wealth. If those forms still name your ex, your current spouse and children may inherit nothing from those accounts, regardless of what your will says.

Why Federal Law Makes This Worse

You might assume your state has your back. Many states have "revocation upon divorce" statutes that automatically void an ex-spouse's beneficiary designation when a marriage ends. Virginia, Washington, and roughly half the states have some version of this law on the books.

But here's the problem: federal law doesn't care.

The Employee Retirement Income Security Act of 1974 (ERISA) governs most employer-sponsored retirement plans — your 401(k), 403(b), pension, and employer-provided life insurance.[1] ERISA includes a preemption clause that overrides state law whenever the two conflict. And the Supreme Court has made it clear, repeatedly, that ERISA means what it says.

In Egelhoff v. Egelhoff (2001), David Egelhoff designated his wife as the beneficiary of his Boeing pension and life insurance. They divorced. Two months later, he died. Washington state law would have automatically revoked the ex-wife's designation — but the Supreme Court ruled that ERISA preempted Washington's statute. The ex-wife received the proceeds. His children from a prior relationship got nothing.[2]

The Court's reasoning was straightforward: ERISA was designed to create uniform national rules for employee benefit plans. Allowing 50 different state laws to alter who receives plan benefits would undermine that uniformity. The plan administrator's job is simple — look at the beneficiary form and pay whoever is named on it.

Eight years later, the Court doubled down. In Kennedy v. Plan Administrator for DuPont Savings and Investment Plan (2009), William Kennedy's divorce decree explicitly stated that his ex-wife, Liv, waived all rights to his retirement benefits. William never updated his beneficiary form. When he died, the plan administrator paid Liv anyway — and the Supreme Court unanimously agreed that the plan was right to do so.[3]

Read that again. Even when a divorce decree specifically says an ex-spouse has no claim to the retirement account, the plan administrator still pays whoever the form names.

“"The plan administrator must distribute benefits in accordance with the plan documents. A divorce decree, standing alone, is not a plan document." — Kennedy v. Plan Administrator for DuPont Sav. and Inv. Plan, 555 U.S. 285 (2009)”

It's Not Just Retirement Accounts

The same logic applies to federal employee life insurance. In Hillman v. Maretta (2013), Warren Hillman named his first wife, Judy Maretta, as the beneficiary of his Federal Employees' Group Life Insurance (FEGLI) policy in 1996. They divorced in 1998. Hillman remarried in 2002 but never updated the form. When he died in 2008, Maretta received $124,558. Hillman's widow, Jacqueline, sued under a Virginia statute that would have revoked the designation — but the Supreme Court held that federal law preempted Virginia's statute entirely.[4]

Three Supreme Court cases. Three deceased individuals who assumed the divorce took care of everything. Three ex-spouses who walked away with the money.

These aren't edge cases. This is how the law works by default.

The Accounts You Need to Audit

If you've been through a divorce, here's every account type where a stale beneficiary designation could redirect your wealth to the wrong person:

ERISA-governed accounts (federal law controls):

  • 401(k) and 403(b) plans
  • Defined benefit pension plans
  • Employer-provided life insurance (group policies)
  • Employer-provided accidental death & dismemberment (AD&D) insurance

Non-ERISA accounts (state law may help, but don't count on it):

  • Individual life insurance policies
  • Traditional and Roth IRAs
  • Annuities
  • Payable-on-death (POD) bank accounts
  • Transfer-on-death (TOD) brokerage accounts
  • Health Savings Accounts (HSAs)

For ERISA-governed accounts, the beneficiary form is the only document that matters. For non-ERISA accounts, some states do have revocation-upon-divorce statutes that might protect you — but relying on a state statute when you could simply update a form is a gamble with your family's financial future.

The Blended Family Multiplier

Divorce doesn't just create a beneficiary problem. It creates a compounding beneficiary problem once you remarry and build a blended family.

Consider a common scenario: you have two children from your first marriage and a new spouse. You assume your current spouse will inherit your 401(k) and take care of the kids. But if your beneficiary form still lists your ex, your current spouse gets nothing from that account. Your children from the first marriage also get nothing. The only person who benefits is the one you divorced.

Even if you do update your 401(k) to name your current spouse, ERISA requires spousal consent before you can name anyone other than your current spouse as the primary beneficiary. That's a protection for current spouses — but it also means your children from a prior marriage can't be named as primary beneficiaries without your current spouse signing a waiver.

Blended families face a web of these conflicts. If your situation involves stepchildren, children from multiple marriages, or assets in multiple states, the stakes are exponentially higher. We wrote a dedicated guide on this: Blended Family Estate Planning: The Step-Child Blind Spot.

The QDRO: The One Tool Most People Forget

There is one mechanism that can override an ERISA beneficiary designation during a divorce: a Qualified Domestic Relations Order, or QDRO.[5]

A QDRO is a court order that directs a retirement plan administrator to pay a specific portion of plan benefits to an alternate payee — typically an ex-spouse or child. Unlike a regular divorce decree, a QDRO is recognized by ERISA as a valid plan document. It's the only way to legally divide ERISA-governed retirement assets as part of a divorce settlement.

But here's the catch: a QDRO only addresses the division of existing benefits at the time of divorce. It doesn't automatically change the beneficiary designation going forward. After the QDRO splits the account, you still need to file a new beneficiary form naming whoever you want to inherit your remaining share.

Many divorce attorneys handle the QDRO but don't follow up on the beneficiary designation. And many newly divorced individuals assume the QDRO took care of everything. It didn't.

What You Can Do This Week

You don't need a financial planner or an attorney to start fixing this. Most of these steps take less than an hour.

1. Pull every beneficiary form you have on file. Call your employer's HR department and ask for copies of your current beneficiary designations on your 401(k), pension, and group life insurance. Log into your IRA custodian's website and check those designations too. Check any POD or TOD registrations at your bank and brokerage. Make a list.

2. Update every form that still names your ex-spouse. For ERISA-governed plans, submit a new beneficiary designation form to your plan administrator. For IRAs and other non-ERISA accounts, update the designation through your custodian's website or by submitting a new form. Keep copies of everything you submit.

3. Coordinate your beneficiary designations with your will and trust. Your estate attorney should see the full picture — not just the documents they drafted, but every beneficiary form across every account. The goal is alignment: your will, your trust, and your beneficiary designations should all tell the same story about where your assets go. If you're navigating a complicated family situation, this coordination becomes even more critical.

4. Set a calendar reminder to review beneficiaries annually. Life changes — remarriage, new children, deaths in the family — happen between estate planning updates. A once-a-year review ensures your forms stay current. Tools like Heirloom can help you keep all of your designations, documents, and family details organized in one place so nothing falls through the cracks.

5. If you have a blended family, get professional help. The intersection of ERISA rules, state law, QDROs, and multiple sets of children is genuinely complex. A fee-only financial planner or estate attorney who specializes in blended families can spot conflicts you'll miss on your own.

None of this is glamorous work. Updating a beneficiary form doesn't feel like protecting your family. But the families in Egelhoff, Kennedy, and Hillman would tell you otherwise — if the right people had received the money, they never would have ended up in court at all.

The form takes five minutes. The consequences of not updating it last forever.
