A carefully written will can spell out exactly who should inherit a family’s retirement accounts and insurance — and be completely powerless to make it happen. On those particular assets, a separate form filed years earlier, often forgotten, controls where the money goes. For older Americans whose largest holdings sit in retirement plans and insurance policies, an outdated line on that form can quietly route a lifetime of savings to the wrong person.
Why the beneficiary form beats the will
Certain assets do not pass through a will at all. Retirement accounts such as 401(k)s and IRAs, life insurance policies, and annuities transfer directly to whoever is listed on the account’s beneficiary designation form. That designation is a binding contract between the account holder and the institution, and it legally overrides the instructions in a will — even a newer, professionally drafted one.
The practical consequence surprises many families. A will might leave “all my assets equally to my children,” yet if an IRA still names a different person as beneficiary, that IRA goes to the named person, full stop. The executor cannot redirect it, and the heirs named in the will have little recourse. Because retirement and insurance assets often represent the bulk of an older household’s wealth, this is not a technicality — it can determine who receives the largest share of an estate.

The costly mistakes FINRA sees most
The Financial Industry Regulatory Authority warns that a stale or forgotten beneficiary designation is one of the most common and expensive estate-planning errors. The classic example is an ex-spouse who was never removed from a retirement account or life insurance policy after a divorce; unless the form is updated, that former spouse can legally inherit the money regardless of what the will or a divorce decree says. FINRA’s guidance on checking beneficiary designations lays out how often these oversights derail a family’s intentions.
Other mistakes are subtler. If the named beneficiary has died and no contingent, or backup, beneficiary was listed, the asset can be forced into probate — the court process the account was meant to avoid — adding delay, cost, and public exposure. Children and grandchildren born or adopted after the form was last signed can be left out entirely, simply because no one went back to add them. In each case the money still follows the paperwork, not the family’s wishes.
The stakes are magnified by how much of a retiree’s wealth these accounts can hold. For many older households, the balances in IRAs, 401(k)s, and life insurance dwarf what sits in a checking account or passes through the will, so a single outdated form can misdirect a larger sum than any other part of the estate. A designation that made perfect sense when a policy was opened decades earlier may point to a person who is no longer part of the picture, or split the money in proportions the account holder would never choose today. Because the transfer happens automatically and quickly after death, there is rarely a chance to catch and correct the error once it takes effect.
Naming primary and contingent beneficiaries
FINRA points to a straightforward safeguard: name both a primary beneficiary and at least one contingent beneficiary on every account that uses a designation. The primary beneficiary is first in line; the contingent inherits only if the primary cannot, such as when the primary has already died. That second layer keeps an asset from defaulting into probate when the unexpected happens, and it preserves the account’s chief advantage — a direct, private transfer to a chosen heir.
Consistency across the whole plan matters just as much as filling in the blanks. Beneficiary designations should line up with the overall estate plan so the will and the account forms are telling the same story rather than contradicting one another. When they conflict, the designation wins on the assets it covers, which can unravel an otherwise thoughtful plan. Keeping the two in agreement is what ensures the money actually reaches the people the account holder intended.
Reviewing forms after every major life event
The reason these errors persist is that beneficiary forms are set once and rarely revisited, while life keeps changing around them. FINRA advises reviewing designations after any major life event — a marriage, a divorce, the birth or adoption of a child or grandchild, or the death of a spouse or another named beneficiary. Each of those moments is a signal to pull up every retirement account, insurance policy, and annuity and confirm the names still reflect current wishes.
The review itself is usually quick and free. Most institutions allow a beneficiary update through an online account or a simple form, and there is no cost to confirm that the right people are listed. For a retiree, that modest effort protects the assets that make up the largest part of many estates, and it spares heirs the expense, delay, and family friction that follow when the money lands with the wrong person. Checking the forms is far easier than untangling the consequences of leaving them stale.
