Beneficiary Designations: The Detail People Forget

You can spend hours getting your will exactly right, then have it quietly overruled by a form you filled out years ago and forgot. Beneficiary designations are the most overlooked piece of estate planning, and in New York City we see the consequences constantly. Here’s what worries clients most.

Wait, a form can override my will?

Yes, and this is the part that shocks people. Your will controls assets that pass through probate. But your 401(k), IRA, life insurance, and payable-on-death bank or brokerage accounts pass by beneficiary designation, completely outside your will and outside Surrogate’s Court. If your will leaves everything to your spouse but your old life insurance policy still names an ex, the ex wins. The contract beats the will.

What’s the most common mistake you see?

Outdated names. A Brooklyn client names a sibling on a retirement account in their twenties, marries, has kids, and never updates the form. Decades later, the sibling inherits a six-figure account while the spouse and children are left out. Divorce is another classic trap, an ex-spouse may stay on a 401(k) for years after the marriage ends. These aren’t rare; they’re the rule when nobody reviews the paperwork.

What happens if I leave a designation blank?

Then the asset usually goes to your estate by default, which drags it into probate, the very thing many of these accounts are designed to avoid. Naming no one, or naming “my estate,” can also create income tax disadvantages on retirement accounts and slow everything down in a NYC Surrogate’s Court. Filling out the form, and naming a contingent beneficiary too, keeps the asset moving directly to the people you intend.

Should I ever name a minor child directly?

Be careful here. If you name your young child as the direct beneficiary of a large life insurance policy, the money can’t simply be handed to a kid; a court-supervised guardianship of the property may be required, with oversight until age 18. Many NYC parents instead name a trust as the beneficiary, so a trustee manages the funds on the child’s terms. Coordinating designations with your will and any trust is where plans either hold together or fall apart.

How do designations affect New York estate tax?

People assume these assets are “off the books.” They’re not. Life insurance and retirement accounts are still part of your taxable estate for New York purposes. With New York’s 2026 estate tax exclusion at $7,350,000, and a cliff at $7,717,500 where exceeding the threshold can tax the entire estate, large designations matter. Ignoring them while planning around the cliff is a real risk for higher-net-worth city households.

How often should I check these?

At least every few years, and immediately after any marriage, divorce, birth, death, or job change, since a new employer means a new 401(k) with its own form. Pull up each account, confirm the primary and contingent beneficiaries, and make sure they match the rest of your plan. It takes an afternoon and prevents a tragedy.

A note before you file anything

Beneficiary designations have to be coordinated with your will, your trusts, and New York’s tax rules, not filled out in isolation. A qualified New York estate planning attorney can review every account alongside your plan so one stale form doesn’t undo everything else you’ve built.
