A $500,000 IRA Went Through Probate Instead of to the Kids, Because of a Beneficiary Form From 1998.

Quick Read

• A retirement account's beneficiary form legally overrides any will, so an outdated 1990s form can send hundreds of thousands of dollars through costly probate.

• Rollovers to new custodians often reset beneficiary designations to the estate default, a pitfall most account holders never notice.

• Under the SECURE Act, an account passing through an estate instead of a named beneficiary can shrink the distribution window from 10 years to 5, costing six figures in taxes.

Attorneys who handle estate work describe versions of the headline scenario every year: a retirement account opened in the late 1990s, a beneficiary form completed once and never revisited, and a family that assumed a more recent will would control the outcome. It does not. Under federal rules, a beneficiary designation on a 401(k) or IRA controls the account, regardless of what a later will says. When the named person has died, cannot be located, or was removed from the family through divorce, the account can default to the estate and land in probate.

That outcome is expensive and slow, and probate typically involves court and attorney fees, as well as a public process that can stretch over many months. It can also collapse the tax planning that makes an inherited IRA useful in the first place, because an estate is generally not a designated beneficiary for tax purposes.

Why the Form Beats the Will

Retirement accounts pass by contract, and the custodian is instructed to distribute the balance to whoever is named on file at the moment of death. A will can direct almost every other asset a person owns, but it cannot override that contract. A 2012 Department of Labor review of beneficiary practices found that the most frequent disputes involved participants who married or divorced and never updated their designations, resulting in assets moving in ways the deceased would not have chosen.

A 1998 form is a common vintage for a reason. Many workers opened IRAs during the late 1990s bull market, filled out paperwork once, rolled the account between custodians, and assumed the beneficiary information carried forward. It often does not. Rollovers can reset the designation to the default, which in many custodial agreements is the estate.

What Is at Stake for the Average Household

A $500,000 IRA is well above average, but the underlying account type is mainstream. Fidelity's Q1 2026 retirement analysis reported average IRA balances in the low six figures, according to industry retirement analyses. That figure reflects tens of millions of accounts, many of them decades old and held by people who no longer remember which form they signed.

Households have less cushion to absorb an estate mistake than they did a year ago. The Bureau of Economic Analysis reported a personal savings rate of 3.9% in Q1 2026, down from the 5.0% rate in Q2 2025. Per capita disposable income is $68,391, leaving little room for heirs to write checks to probate attorneys while waiting for a distribution.

The Mistakes That Create These Situations

Estate attorneys point to a short list of recurring errors on retirement account forms:

1. Naming an ex-spouse and never updating the form after divorce.

2. Naming the estate directly forces the account into probate by design.

3. Naming a primary beneficiary but no contingent beneficiary, so the account defaults to the estate if the primary predeceases the owner.

4. Naming minor children without a trust, which requires court-appointed guardianship of the funds.

5. Assuming a rollover to a new custodian carried the old beneficiary information forward.

A 2025 Caring.com survey found that only about a quarter of Americans have a will. The share of those who have reviewed a retirement account beneficiary form in the past year is smaller still. For accounts opened in the 1990s, the odds that the current form reflects the current family are low.

What the SECURE Act Changed

The stakes have grown since 2020. Under the SECURE Act, most non-spouse beneficiaries must empty an inherited IRA within 10 years of the original owner's death. When an account lands in the estate instead of passing to a named individual, that window can shrink to five years, and the ability to spread distributions across a beneficiary's lifetime disappears. On a $500,000 balance, the difference between a stretched distribution and a compressed one can move the tax bill by six figures.

What the Data Suggests Reviewing

Financial planners generally suggest pulling every retirement account beneficiary form once a year, and again after any marriage, divorce, birth, or death in the family. That includes 401(k) accounts left with former employers, rollover IRAs, Roth IRAs, and any annuities or life insurance policies held alongside them. The Federal Funds Rate sits at 3.75% as of July 30, 2026, which shapes the return environment for these accounts but has no effect on how they transfer at death. That outcome is decided by a single sheet of paper on file with the custodian, whatever year it happens to be from.
