Beneficiary designations: why they can override your will

Mark got married to his second wife, Elena, in 2011. He updated his will, they bought a house together, and he told her more than once that she'd be taken care of. When he died suddenly at 58, Elena learned that the $400,000 life insurance policy through his job still listed his first wife, a woman he'd divorced fourteen years earlier. The will didn't matter. The form did.

Stories like this are common enough that estate attorneys tell them at dinner parties. Beneficiary designations are the short forms attached to your retirement accounts, life insurance, and many bank and brokerage accounts that say who gets the money when you die. They are often worth more than everything your will controls, and most people fill them out once, on their first day at a new job, and never look at them again. This guide explains how beneficiary designations work, why they usually beat your will, and the mistakes that send money to the wrong person. It's general information, so for your specific situation, an estate planning attorney is worth the call.

What is a beneficiary designation?

A beneficiary designation is an instruction you give a financial institution naming who should receive an account or policy when you die. It's a contract between you and that company, and it works independently of your will.

You've probably filled out more of these than you remember. They show up on:

Employer retirement plans like a 401(k) or 403(b), plus IRAs and Roth IRAs
Life insurance policies, including group coverage through work
Annuities
Bank accounts set up as "payable on death" (POD)
Brokerage accounts registered as "transfer on death" (TOD)

Some states also allow transfer-on-death deeds for real estate and TOD registration for cars, which work on the same principle.

When you die, your beneficiary contacts the institution with a death certificate and a claim form, and the money goes to them directly. There's no judge involved and no waiting for the estate to settle. That speed is the whole point, and it's a good one. It's also why a stale form can do so much damage.

Why beneficiary designations override your will

Your will only controls property that passes through probate. Anything with a named beneficiary skips probate entirely, so the will never touches it.

That catches a lot of people off guard. If your will says "everything to my three children equally" but your IRA names only your oldest daughter, your oldest daughter gets the IRA. Your other two kids split whatever is left in the probate estate, which might be a car and a checking account. Your daughter may choose to share, and plenty of people do, but she has no legal obligation to. (If you want the full picture of what goes through court and what doesn't, our explainer on what probate is and how long it takes covers it.)

Divorce makes this messier. Many states have laws that automatically cancel an ex-spouse as beneficiary after a divorce, but those laws don't always apply. Employer-sponsored plans like Mark's group life insurance and most 401(k)s fall under a federal law called ERISA, and in Egelhoff v. Egelhoff, the U.S. Supreme Court held in 2001 that ERISA overrides those state revocation laws. The plan administrator pays whoever is named on the form. In a later case, the Court sided with an ex-wife who had even waived her rights in the divorce decree, because the plan documents still listed her.

I find that ruling hard to read without wincing, but the logic is simple. Plan administrators handle millions of accounts and can't investigate every family's history. They follow the paperwork. So you have to make sure the paperwork says what you mean.

Primary vs. contingent beneficiaries

Most forms ask for two tiers. Your primary beneficiary gets the account first. Your contingent beneficiary is the backup, and only inherits if no primary beneficiary is alive to claim it.

Leaving the contingent line blank is one of the most common mistakes, and it's easy to see why. When you're 31 and naming your spouse, it doesn't feel urgent to name anyone else. But couples sometimes die in the same accident, and people outlive the person they named. If there's no living beneficiary on the form, the account usually defaults to your estate. That pulls it back into probate, delays it by months, and can strip away some of the tax advantages your heirs would otherwise have.

You can also split each tier by percentage. A typical setup might be 100% to a spouse as primary, then 50% each to two children as contingents. Just make sure the percentages add up to 100, because forms that don't get rejected or, worse, quietly misread.

Per stirpes and per capita

These two Latin phrases matter more than they look. Say you name your three kids equally and one of them dies before you, leaving two children of her own.

"Per stirpes" means her share flows down to her kids. Your grandchildren split her third.

"Per capita" (in the version most forms use) means her share is divided among the surviving beneficiaries you named. Your other two kids each get half, and her children get nothing from that account.

Neither is wrong. Plenty of people want per stirpes because it keeps each branch of the family whole, and some forms default to per capita without asking. Check which one yours uses.

Common beneficiary designation mistakes

These are the situations that come up again and again when families try to settle an estate.

Never updating after a life change. Marriage, divorce, a new baby, or a death in the family should all trigger a review. Mark's form was filled out in 1998.
Naming a minor child directly. Insurers and plan custodians generally won't hand $250,000 to a nine-year-old, so a court may need to appoint a guardian of the estate to manage it until the child turns 18. Then the child gets it all at once. Naming a trust, or a custodian under your state's Uniform Transfers to Minors Act, gives you more control.
Naming someone who receives disability benefits. A direct inheritance can push a person over the asset limits for SSI or Medicaid. A special needs trust can receive the money instead, but it needs to be set up properly by an attorney.
Naming "my estate." This forces the money through probate, the exact thing beneficiary designations are designed to avoid, and for retirement accounts it can shorten how long heirs have to withdraw the money.
Forgetting accounts exist. That old 401(k) from a job you left in 2006 still has a beneficiary form, and it may still name a college girlfriend.

The last one is more common than people expect. The National Association of Insurance Commissioners runs a free Life Insurance Policy Locator because so many families don't know which policies a parent had. You can save your family that search by writing it all down now.

Retirement accounts and the 10-year rule

Retirement accounts come with their own tax rules, and those rules affect who you might want to name.

A surviving spouse who inherits an IRA or 401(k) has the most flexibility, including the option to treat the account as their own. Most other beneficiaries, including adult children, now have to empty an inherited account within 10 years under the SECURE Act, which took effect in 2020. Some people get exceptions, such as minor children of the account owner (until they reach adulthood), people who are disabled or chronically ill, and beneficiaries not more than 10 years younger than you. The IRS page on retirement plan beneficiaries lays out the details.

For 401(k)s and other ERISA plans, there's another wrinkle. If you're married, your spouse is generally entitled to the account unless they sign a written, notarized or witnessed waiver. You can't just write in your kids' names and be done. IRAs don't have that federal requirement, though some community property states have their own rules.

You don't need a spreadsheet of tax projections for this. But "who should get my 401(k)?" and "who should get my house?" might have different answers, and a financial advisor or tax preparer can help you think it through.

How to review your beneficiary designations

Reviewing beneficiary designations takes about an hour for most people, and you can do it from your couch.

Start by making a list of every account that might have one. Think about your current and past employers' retirement plans, any IRAs, every life insurance policy (including the small one that came with your credit union membership), annuities, and bank and brokerage accounts. If you have a letter of instruction or an account inventory already, that's your starting list.

Then log into each one, or call, and look at who's actually named, which may be different from who you remember naming. Rosa, a retired teacher in Ohio, did this after her husband died and found that her pension listed him as sole beneficiary with no contingent. Her two sons were on nothing. It took her one afternoon and four forms to fix, and she said the relief afterward was bigger than she expected.

While you're there, check that names are spelled correctly and that you've used full legal names rather than "my kids." Adding birthdates or the last four digits of a Social Security number, if the form allows, helps the institution find the right person years from now.

Finally, compare the whole picture against your will. If your will splits things one way and your beneficiary forms split them another, decide which version you actually want and make them agree. If you've set up a living trust, ask your attorney whether some accounts should name the trust. Our guide to will vs trust explains how those pieces fit together.

The form that does the quiet work

Elena eventually got some help. Mark's ex-wife, to her real credit, gave back part of the money, and the house was in both their names. But she spent most of the first year after his death in lawyers' offices instead of grieving, and she told a friend that the hardest part was that he had meant to do it. He just never got around to the form.

That's what makes this one worth an hour of your weekend. Your will gets the attention and the signing ceremony, but these small forms often move more money, and they move it to exactly whoever is written down. If you'd like somewhere to keep a list of every account and who it goes to, When I Die Files can hold that alongside a note explaining your choices, so the person who inherits your IRA also knows why you set it up the way you did. Even just pulling up your 401(k) beneficiary tonight is a fine place to start.
