A beneficiary designation form can be filled out in about two minutes. It also overrides a will, a trust, and any subsequent instruction the account holder gave verbally or in writing. When one is left blank, outdated, or names a person who has since died, the account it governs can be forced into probate.
That is what reportedly happened to a $500,000 IRA whose owner had filled out a paper form in 1998 naming a spouse who predeceased him, never updated it, and assumed his will would send the money to his children, which it did not.
The mechanics here are governed by contract law. Retirement accounts pass by contract rather than by will. Whoever’s name is on the custodian’s beneficiary form at the time of death is the one who receives the money. If that name is a deceased person, a former spouse, or no one at all, the account typically defaults to the estate, which drops it into probate.
Probate exposes the balance to creditors, court fees, and delays that can run a year or longer, and it strips out the tax deferral that makes an IRA valuable in the first place. An inherited IRA passing to named individuals can often be stretched over ten years. An IRA passing through an estate generally must be drained within 5 years.
What Is Actually at Stake
The dollar figure in this case is not unusual for older account holders. Fidelity’s Q3 2025 Retirement Analysis puts the average IRA balance for Baby Boomers at $257,002, and their average 401(k) balance at $267,900. Households with both, plus decades of continuous saving, routinely clear the $500,000 mark. Fidelity counted 559,181 IRA millionaires and 654,000 401(k) millionaires as of Q3 2025. Every one of those accounts is governed by a beneficiary form that most owners have not looked at in years.
The broader retirement picture makes the stakes clearer. Total U.S. retirement assets stood at $48.1 trillion in Q3 2025, roughly 34% of all household financial assets. A large share of that wealth is set to change hands over the next two decades, and the paperwork controlling the transfer was, in many cases, filled out on carbon-copy forms before the account custodian’s current computer systems existed.
Why Outdated Forms Are So Common
The 1998 scenario tends to emerge from three common patterns. Custodians are acquired, or change recordkeepers, and older paper forms are often reimaged but rarely re-solicited. Life events like marriage, divorce, remarriage, the birth of children, or the death of a named beneficiary tend to prompt updates to wills but not to plan paperwork. And plan participants who roll over a 401(k) into an IRA frequently assume the rollover carries their old designations, though that is typically not the case.
The new IRA starts with a blank slate unless the owner completes a fresh form. The consequences get magnified by how little cushion the average household has to absorb an unexpected legal bill or delay. The personal savings rate dropped from 6.2% in the first quarter of 2024 to 2.8% in the second quarter of 2026. Per capita disposable income has risen to $68,958, yet average annual household expenditures hit $78,535 in 2024. Heirs counting on an inherited IRA to close that gap can end up waiting a long time for probate to release the funds.
What the Data Points To
A beneficiary review is one of the few estate-planning tasks that cost nothing and take minutes. Three specific checks match the failure modes above:
A current beneficiary form exists for every IRA, 401(k), 403(b), pension, life insurance policy, and annuity. Primary and contingent beneficiaries are listed by name, and any named person is still alive and still the intended recipient.
After any rollover, remarriage, divorce, or death in the family, a fresh form is typically required rather than a carryover of the old one. Custodians treat rollovers as new accounts.
Where minor children are the intended heirs, a trust or a custodian under the state’s Uniform Transfers to Minors Act is often used rather than naming the children directly, since custodians will not pay IRA proceeds to a minor without court involvement.
The IRA in the opening example did eventually reach the children. It arrived smaller, later, and taxed more heavily than a two-minute form update in any year between 1998 and the account holder’s death would have allowed.
