Beneficiary Designations: The Estate Planning Step Most People Forget

Quick answer: Beneficiary designations on life insurance policies, retirement accounts (401(k), IRA, 403(b)), and bank accounts directly override your will. They pass assets immediately outside of probate to whomever is named — even if that's your ex-spouse, a deceased parent, or someone you haven't spoken to in decades. Reviewing and updating your beneficiary designations is one of the highest-impact, lowest-cost steps in estate planning — yet most people never do it after major life events.

I've seen it more times than I can count in my 20 years of practice: a client spends $2,000 drafting a careful will, then dies with a 20-year-old beneficiary designation that routes their largest asset — a $400,000 IRA — directly to an ex-spouse. The will is irrelevant. The designation controls. Don't let this happen to you.

What Is a Beneficiary Designation?

A beneficiary designation is a direct instruction to a financial institution or insurance company about who should receive the assets in a specific account when you die. You fill out a beneficiary form when you open the account — and it controls the outcome entirely, regardless of what your will says.

Accounts that use beneficiary designations include:

• Life insurance policies
• 401(k), 403(b), 457(b) plans
• Traditional and Roth IRAs
• Pension plans
• Annuities
• Health Savings Accounts (HSAs)
• Payable-on-Death (POD) bank accounts
• Transfer-on-Death (TOD) brokerage accounts

In aggregate, these "non-probate" assets often represent the majority of a person's wealth — far more than the assets covered by a will. Yet they're frequently ignored after initial setup.

Why Beneficiary Designations Override Your Will

This is the most important concept in this entire guide: beneficiary designations are a separate legal contract between you and the financial institution. They operate independently of your will or trust.

When you die, the financial institution pays directly to whoever is named. The probate court has no jurisdiction. Your will has no power. The money does not pass through your estate — it goes directly to the designated beneficiary.

Primary vs. Contingent Beneficiaries

Every beneficiary designation form has at least two tiers:

Primary Beneficiary

The first person or entity in line to receive the asset. If your primary beneficiary is alive and able to receive the inheritance when you die, they get it — period.

Contingent Beneficiary

Also called a "secondary beneficiary," this person receives the asset only if the primary beneficiary has died before you, declines the inheritance, or cannot otherwise receive it. If there's no living contingent beneficiary, the asset typically falls into your estate and goes through probate.

Always name at least one contingent beneficiary. The failure to do so is one of the most common and costly estate planning mistakes. If your primary beneficiary dies in a car accident two weeks before you, and there's no contingent, a substantial asset may go through probate — subject to delays, costs, and the default rules of intestacy.

Per Stirpes vs. Per Capita Distributions

When naming beneficiaries, you'll often see two distribution options:

Per Stirpes ("By Branch")

If a named beneficiary dies before you, their share passes to their descendants (children, grandchildren). Example: You name your three children equally. One child predeceases you. With per stirpes, that child's one-third share passes to their children (your grandchildren), not split between your surviving children.

Per Capita ("By Head")

If a named beneficiary dies before you, their share is redistributed equally among the surviving named beneficiaries. Example: With per capita, the predeceased child's share would be divided between your two surviving children, and their children (your grandchildren) receive nothing.

Per stirpes is almost always preferable for families — it ensures your intended bloodline receives your assets even if a named beneficiary dies first.

Accounts That Require Beneficiary Designations

Life Insurance

Life insurance is the most familiar beneficiary designation. Key rules:

• The insurer pays the death benefit directly to named beneficiaries — no probate, no delays
• Name both primary and contingent beneficiaries
• If you name your estate as beneficiary, the proceeds go through probate (usually a mistake)
• If you have a living trust, consider naming your trust as the beneficiary (especially if minor children are involved)
• Update after marriage, divorce, birth of children, and death of any named beneficiary

401(k) and Employer Retirement Plans

Federal law (ERISA) governs retirement plan beneficiaries. Key rules:

• Married participants must name their spouse as primary beneficiary unless the spouse signs a written waiver. This is federal law — your will cannot override it.
• If you want to name someone other than your spouse (even a trust for your children), your spouse must consent in writing with a notary present
• After divorce, some states automatically revoke ex-spouse designations — but federal ERISA preempts state law for 401(k)s, meaning the designation may still be valid until you update it
• Beneficiaries who are not spouses (non-spouse beneficiaries) must follow the 10-year rule under the SECURE Act 2.0: they must withdraw all funds within 10 years of your death

IRAs (Traditional, Roth, SEP, SIMPLE)

IRA beneficiary rules are more flexible than 401(k)s but equally important:

• Spouses who inherit an IRA can treat it as their own — delaying RMDs, stretching tax deferral over their lifetime
• Non-spouse beneficiaries must withdraw everything within 10 years (SECURE Act 2.0)
• Naming a trust as IRA beneficiary can work but requires careful drafting (a "see-through" or "conduit" trust) — otherwise the 10-year rule applies to the trust, not individual beneficiaries
• Never name your estate as IRA beneficiary if avoidable — you lose all stretch benefits and force probate

Payable-on-Death (POD) Bank Accounts

Any bank account can be converted to a POD account by submitting a simple form to your bank. The named beneficiary receives the balance immediately upon your death, without probate. Key points:

• Free to set up — just ask your bank
• The beneficiary has zero access during your lifetime
• Unlike a joint account, a POD beneficiary can't drain your account while you're alive
• Works alongside (not instead of) a will or trust

Transfer-on-Death (TOD) Brokerage Accounts

Brokerage accounts (stocks, bonds, ETFs outside of retirement accounts) can be set up as TOD accounts. The named beneficiary inherits the securities directly, with a stepped-up cost basis (usually), avoiding capital gains taxes on appreciation during your lifetime. TOD designations are available at most major brokerages including Fidelity, Schwab, Vanguard, and Merrill Lynch.

Common Beneficiary Designation Mistakes

1. Naming a Minor Child Directly

Minor children cannot legally manage large sums of money. If a minor is named as beneficiary, a court will appoint a guardian of the property — not necessarily the person you'd choose — to manage the funds until the child turns 18. At 18, the full amount is distributed outright, regardless of maturity. Better approach: name a trust as beneficiary and name the child as a trust beneficiary with distributions at ages you specify (25, 30, etc.).

2. Forgetting to Update After Divorce

This is the single most common catastrophic mistake. Divorce does not automatically revoke beneficiary designations on federal accounts like 401(k)s and life insurance (state laws may revoke them for state-governed accounts, but federal ERISA preempts this for retirement plans). Update every beneficiary designation on the day your divorce is finalized — or as soon as legally permitted.

3. Naming Your Estate as Beneficiary

Assets that pass through your estate are subject to probate — court-supervised distribution that can take months or years, costs 3–8% of the estate value in fees, and becomes public record. Name individuals or a trust, not your estate.

4. Not Naming a Contingent Beneficiary

If your primary beneficiary dies before you and there's no contingent, the asset goes to your estate. Always name a contingent.

5. Not Coordinating With Your Trust

If you have a living trust, your beneficiary designations should coordinate with it. In many cases, naming your trust as beneficiary (for life insurance, bank accounts) ensures assets flow into the trust and are distributed under its terms — which may include minor child protections, spendthrift provisions, or staggered distributions.

6. Stale Designations From Decades Ago

People change jobs and roll over 401(k)s, open new IRAs, get new life insurance policies — and forget to name beneficiaries on new accounts. A beneficiary designation that was never filled out defaults to your estate, or sometimes to a default hierarchy defined by the plan (spouse first, then children).

How to Name a Trust as Beneficiary

Naming your trust as beneficiary can be the right choice in several situations:

• You have minor children and want the trustee (not a court-appointed guardian) to manage money until children reach adulthood
• You have a beneficiary with special needs who can't receive assets directly without losing government benefits
• You want staggered distributions at certain ages rather than a lump sum at 18 or 21
• You want asset protection for the inheritance (spendthrift provisions)

When naming a trust as beneficiary, provide the full legal name of the trust: "The [Your Name] Revocable Living Trust, dated [Date], [Your Name] as Trustee."

For IRA beneficiaries specifically, ensure the trust qualifies as a "see-through trust" — meaning trust beneficiaries are identifiable — so the 10-year distribution window applies to individual beneficiaries rather than forcing immediate distribution to the trust.

Your Beneficiary Designation Audit: What to Do Right Now

Take these steps within the next 30 days:

1. Make a complete list of all accounts with beneficiary designations: all life insurance policies, all retirement accounts (including old employer 401(k)s you may have forgotten), all IRAs, all annuities, all bank accounts, all brokerage accounts
2. Request current beneficiary designations from each institution — call, log in online, or visit a branch
3. Compare against your current intentions — does each designation reflect who you actually want to receive the asset? Are any ex-spouses, deceased people, or estranged relatives still named?
4. Update as needed — most updates can be done online in minutes. Life insurance may require a paper form mailed to the insurer.
5. Confirm receipt and processing — follow up to ensure the new designation was recorded, not just submitted
6. Repeat every 3–5 years and after any major life event

Beneficiary Designations and Estate Taxes

Even assets that pass outside of probate via beneficiary designations are generally included in your taxable estate for federal estate tax purposes. The federal estate tax exemption in 2026 is $13.99 million per individual ($27.98 million for married couples using portability). If your estate is under these thresholds, estate taxes are not a concern. But for larger estates, the way beneficiary designations interact with trusts (particularly AB trusts or QTIP trusts) can significantly affect the tax bill.
