Beneficiary Designations vs. Will: Which Controls (2026)

Does a Beneficiary Designation Override a Will?

Yes — and by a wide margin. A beneficiary designation is a direct contractual instruction to a financial institution; it transfers the named account to the named person immediately upon your death, completely outside of probate, regardless of anything your will says. Your will only governs assets that have no surviving joint owner and no named beneficiary. For most Americans, retirement accounts and life insurance — often their two largest assets — never touch the will at all.

Key takeaways

• A beneficiary designation legally overrides your will for every account that has one: IRAs, 401(k)s, life insurance, annuities, and payable-on-death bank accounts.
• Your will controls only probate assets — property with no surviving joint owner and no named beneficiary.
• ERISA (29 U.S.C. § 1144) makes federal law supreme over state law for employer-sponsored retirement plans; divorce does not automatically remove an ex-spouse from a 401(k).
• The SECURE Act of 2019 introduced a 10-year withdrawal deadline for most non-spouse inherited IRAs, with IRS final regulations taking full effect in January 2025 — making a misnamed IRA beneficiary significantly more costly than it was before.
• Updating your will after a life event without also updating your beneficiary designations leaves the designations in place, ready to override whatever your will says.

Which Assets Does Your Will Control vs. a Beneficiary Designation?

Most estates split into two tracks the moment the account owner dies. Understanding the split is the foundation of coordinated estate planning.

Asset type	Governed by	Probate required?	Will can control it?
401(k), 403(b), pension (employer-sponsored)	ERISA / plan documents	No	No
Traditional IRA, Roth IRA	IRA custodian agreement + state law	No	No
Life insurance (individual policy)	Insurance contract + state law	No	No
Life insurance (employer group plan)	ERISA / plan documents	No	No
Payable-on-death (POD) bank account	State law	No	No
Transfer-on-death (TOD) brokerage account	State law	No	No
Annuity with named beneficiary	Contract + state law	No	No
Real estate (joint tenancy / right of survivorship)	State property law	No	No
Real estate (sole ownership, no trust)	Will / intestacy	Yes	Yes
Personal property (furniture, jewelry, vehicles)	Will / intestacy	Yes	Yes
Bank/investment account (no POD/TOD)	Will / intestacy	Yes	Yes

The pattern is consistent: any asset governed by a contract with a financial institution bypasses your will. Any asset you hold outright, with no such contract, goes through probate and falls under your will — or, if you die without a will, under your state's intestacy statute.

The practical implication: for many middle-class households, the retirement account and life insurance together represent 60–80% of net worth — and both sit entirely outside the will.

The Two-Track Problem: A Worked Example

Meet Maya, 58, divorced in 2022 and remarried to David in 2024. She has a freshly updated will signed in early 2025 that leaves everything to David and her two adult children, Sofia and Lucas, equally. Here is her actual asset picture:

Asset	Value	Title / Designation	Who gets it if Maya dies today?
Primary home	$540,000	Joint tenancy with David	David (survivorship — will irrelevant)
401(k) at current employer	$320,000	Names Carlos (ex-husband), set at 2018 enrollment	Carlos — ERISA controls; state divorce law preempted
Traditional IRA (rollover)	$95,000	Names Carlos; Maya lives in California	Likely fails under Cal. Prob. Code § 5040 — falls to contingent or estate
Individual term life insurance	$500,000	Updated in 2023 — names Sofia 50%, Lucas 50%	Sofia and Lucas (correct)
Checking account (no POD)	$18,000	Sole ownership, no designation	Probate → split per will among David, Sofia, Lucas
Jewelry, furniture, car	$22,000	Personal property	Probate → split per will

Maya's well-drafted will does exactly nothing for the 401(k). Carlos — her ex-husband — receives $320,000 because Maya never filed a new beneficiary designation form with her plan administrator after the divorce. ERISA requires the plan to follow "the documents and instruments governing the plan," per 29 U.S.C. § 1104(a)(1)(D), confirmed by the Supreme Court in Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009). David and the children inherit the probate assets and the life insurance — the much smaller pile.

Had Maya spent 15 minutes submitting a new 401(k) beneficiary form after her 2022 divorce, the outcome would have matched her will. The fix is free and takes one form. The failure cost her family $320,000.

The SECURE Act Just Made Getting This Wrong More Expensive

Before 2020, a non-spouse who inherited an IRA could "stretch" withdrawals over their own life expectancy — a 45-year-old child inheriting a parent's $400,000 IRA could spread distributions over decades, keeping most of the money growing tax-deferred. The SECURE Act of 2019 eliminated that option for most non-spouse beneficiaries.

Under the SECURE Act's 10-year rule, a non-spouse designated beneficiary who inherits an IRA from someone who died after December 31, 2019, must withdraw the entire balance by the end of the tenth calendar year after the owner's death. IRS final regulations issued July 19, 2024 — and taking effect in January 2025 — further clarified that if the original owner had already begun taking required minimum distributions (RMDs), the beneficiary must also take annual RMDs during years one through nine, with the remaining balance cleared by year ten.

This compounds the cost of a misnamed beneficiary in two ways:

1. Wrong person gets the account. Carlos, an ex-spouse with no intended inheritance, receives $320,000.
2. Right people face compressed taxation. Even when the correct beneficiaries inherit, they now face mandatory distributions that can push them into higher tax brackets. A child who inherits a $400,000 traditional IRA must pull out all of it — and pay ordinary income tax on every dollar — within ten years. If that child is in their peak earning years, the tax hit is substantial.

Naming a trust as the IRA beneficiary can provide more control over distribution timing, but trust-as-beneficiary rules are complex — conduit trusts must pass RMDs directly to beneficiaries each year, while accumulation trusts face the highest federal income tax bracket at very low income levels. Either way, a will vs. living trust analysis should account for how the SECURE Act treats trust beneficiaries before that decision is made.

The Divorce Trap: Why Changing Your Will Is Not Enough

After a divorce, most people update their will. Far fewer update their beneficiary designation forms — and the legal consequences of that gap depend sharply on what type of account is involved.

Account type	ERISA applies?	State divorce auto-revocation statute?	What actually happens if you don't update?
401(k), 403(b), employer pension	Yes	Preempted — state law has no effect	Ex-spouse receives the account
Employer group life insurance	Yes	Preempted — state law has no effect	Ex-spouse receives the payout
Traditional / Roth IRA	No	Applies in ~26 states	Varies: ex-spouse may be automatically removed (in auto-revocation states) or may inherit
Individual life insurance	No	Applies in ~26 states	Varies by state
POD bank account	No	Applies in ~26 states	Varies by state

The Supreme Court settled the ERISA question definitively in Egelhoff v. Egelhoff, 532 U.S. 141 (2001), holding that a Washington state revocation-on-divorce statute was preempted because it "interfered with nationally uniform plan administration." ERISA's preemption clause, 29 U.S.C. § 1144, means the plan must follow its own documents — not state family law, not a divorce decree, and not your will.

For non-ERISA accounts, state law does the work in roughly half the country. California automatically revokes a non-probate transfer to a former spouse on dissolution of marriage under Probate Code § 5040 (covering POD accounts, TOD designations, and similar instruments — but note the statute explicitly excludes life insurance policy provisions by its own terms). Pennsylvania automatically revokes former-spouse designations on state-governed accounts under 20 Pa.C.S. § 6111.2. Virginia does the same under Va. Code § 20-111.1. The other roughly 24 states have no automatic-revocation statute — meaning an ex-spouse remains the named beneficiary on an IRA or individual life policy until you change it yourself.

Residents of community property states like California and Texas face additional complexity: a surviving spouse may have community property rights in retirement assets even when someone else is named, and ERISA's spousal consent rules (29 U.S.C. § 1055) require a current spouse to sign off in writing before a non-spouse can be named as primary 401(k) beneficiary.

Never assume your divorce attorney handled this. Changing a 401(k) beneficiary requires a new form submitted directly to your plan administrator — and that form cannot be changed by a court order, a divorce decree, or a will.

How to Coordinate Your Will and Beneficiary Designations

A coordinated estate plan treats both the will track and the designation track as equally important. Here is a concrete process:

1. Make a complete account inventory. List every retirement account, life insurance policy, annuity, bank account, and brokerage account you own. Note the institution, account number, and the name(s) currently on the beneficiary designation.

2. Request copies of your current designations. Call or log into each institution. Many people find designations that name a parent who died decades ago, an ex-spouse, or simply "my estate" — which triggers probate unnecessarily.

3. Draft or update your will. Your will sets the plan for probate assets — personal property, real estate in your name alone, and accounts without designations. Create your will online before tackling designations so you have a clear distribution framework to match against.

4. Align designations to your will's intent. If your will divides your estate equally among three children, your designations should reflect the same allocation. Decide whether to use per stirpes or per capita distribution — per stirpes passes a deceased beneficiary's share to that beneficiary's descendants, which most families intend but rarely specify.

5. Name contingent beneficiaries on every account. A primary beneficiary who predeceases you leaves a designation blank — and a blank designation means probate. Every account should have at least one contingent beneficiary.

6. Decide whether a trust should receive retirement accounts. If you have a beneficiary with special needs, a minor child, or a beneficiary you don't trust to manage a lump sum responsibly, naming a trust can add control. However, given the SECURE Act's 10-year rule, get specific tax advice before doing this.

7. Set a review calendar. Estate planning is not a one-time event. Review every designation immediately after marriage, divorce, the birth of a child, the death of a named beneficiary, or a significant change in the value of any account.

Common Mistakes to Avoid

• Updating only your will after a divorce and assuming that fixes everything. It fixes the probate assets. The 401(k) and life insurance remain unchanged until you file new forms.
• Leaving the primary beneficiary field blank. The account falls into your probate estate — defeating the purpose of a designation and adding delay and expense.
• Naming a minor child directly as beneficiary. A court will appoint a guardian of the property to manage the funds, adding court oversight and fees until the child reaches majority. A trust or UTMA custodianship is almost always better.
• Naming "my estate" as beneficiary of an IRA or 401(k). This drags the account into probate and, for IRAs, eliminates the 10-year stretch under the SECURE Act in favor of a five-year or accelerated payout.
• Forgetting accounts from old jobs. A forgotten 401(k) from a job held twenty years ago still has whatever beneficiary designation you filed at hire.
• Assuming your most recent will controls your most recent beneficiary designation. It does not. A designation filed decades ago will legally override a will signed yesterday for every account that carries it.
