Before You Retire: Update Your 401(k) Beneficiary or Watch $600,000 Go to Your Ex-Spouse

A Georgia attorney described the scene to clients more than once: adult children sitting across the desk after a parent’s funeral, learning that a large six-figure sum in their father’s 401(k) was about to be wired to his first wife, whom he divorced in 1998. The will named the kids. The trust named the kids. The 401(k) beneficiary form, untouched since the Clinton administration, named her. The form won.

This is the most expensive paperwork error in retirement planning, and it is almost entirely preventable. Estate attorneys see it constantly. As one veteran consumer advocate put it, “the money ends up going to the former spouse instead of the current one because they never changed the beneficiary designation on an account set up long ago.”

Why the Form Beats the Will

A 401(k) is governed by ERISA, the federal law that runs employer retirement plans. ERISA tells the plan administrator to pay whoever is named on the beneficiary form. Period. State probate courts cannot override it. Your revocable trust cannot override it. The handwritten letter in your safe deposit box cannot override it. Suze Orman has hammered this point on her podcast for years: “the beneficiary that you have designated on any retirement account will override the wishes of your trust or will.”

The second wrinkle is ERISA’s spousal consent rule. If you are currently married, your spouse is automatically the beneficiary of your 401(k) unless they sign a notarized waiver. Divorce does not undo what you signed years ago. “Just by divorcing your spouse doesn’t mean you’ve divorced their rights to the money that’s in that account.” The form has to be physically changed and re-signed with the new plan administrator on file.

The $620,000 Math

The average 401(k) balance for participants aged 65 to 69 is $251,400, and long-term continuous savers average $613,200 after 15 years of steady contributions. A $620,000 balance is exactly where a disciplined Gen X or Boomer saver lands at retirement. It is also large enough that the tax cascade on the inheriting party matters as much as who gets it.

Under the SECURE Act, a non-spouse adult beneficiary, an adult child, for example, must drain an inherited 401(k) within 10 years. Spread evenly, that is roughly $62,000 a year of additional ordinary income stacked on top of whatever the child already earns. For a 55-year-old child in the 24% federal bracket, that one inheritance pushes them toward the 32% bracket and can trigger IRMAA Medicare surcharges later. An ex-spouse who inherits, by contrast, can roll the balance into her own IRA and stretch withdrawals across her remaining lifetime. The wrong beneficiary does not just get the wrong money. They get the most tax-efficient version of the money.

Three Things to Do Before Monday

Beneficiary audits take about 20 minutes per account and almost no one does them. Here is the short list that actually moves the needle:

1. Pull the primary and contingent beneficiary forms for every retirement account. Log into your 401(k) plan portal, your old employer’s plan if you left a balance behind, and any IRA. Print the current designations. If the contingent line is blank and your primary beneficiary predeceases you, the money falls into probate and the tax stretch disappears.
2. If you remarried, get the spousal consent form notarized. Naming adult children as primary beneficiaries while you are currently married requires your spouse’s signed, notarized waiver on the plan administrator’s form. A waiver buried in a prenup does not satisfy ERISA. The plan needs its own document.
3. Re-confirm after every life event. Divorce, remarriage, the death of a named beneficiary, the birth of a grandchild, or a job change that rolls your 401(k) into a new plan all reset the clock. Old rollovers frequently lose beneficiary data in transit and default to “estate,” which is the worst possible designation for tax purposes.

The will controls the house, the cars, and the brokerage account. The 401(k) form controls the 401(k). Treat it that way.
