Post-Divorce Beneficiary Updates: 401(k), IRA, Insurance, Wills

Your divorce decree divides the marital estate. It specifies who gets the house, how the 401(k) is split, and what happens to the brokerage account. What it does not do — and what federal law prevents it from doing — is automatically update the beneficiary designations on your retirement accounts, life insurance policies, and transfer-on-death registrations. Those designations are separate legal instruments, governed by their own rules, and they override your divorce decree, your will, and your intentions if you fail to update them.

This is not a theoretical risk. In Egelhoff v. Egelhoff, 532 U.S. 141 (2001), the Supreme Court held that ERISA preempted a Washington state revocation-on-divorce statute, awarding the entire proceeds of an employer life insurance plan and pension to the deceased's ex-wife — even though the couple had been divorced for two months and the decedent had two children from the marriage who received nothing from those accounts. The plan documents named the ex-wife; that was the end of the analysis.

The four-account beneficiary audit

After a divorce is finalized, you need to review and update beneficiary designations on four categories of accounts. Each category operates under different legal rules, and the urgency varies:

1. Employer-sponsored retirement plans: 401(k), 403(b), 457(b), pension

Governing law: ERISA (federal) — preempts all state law, including divorce decrees and revocation-on-divorce statutes.

Rule: the beneficiary designation form on file with the plan administrator controls. Period. If your ex-spouse is named, your ex-spouse receives the benefit at your death. The divorce decree is irrelevant. A state revocation-on-divorce statute is irrelevant. Your will is irrelevant.

During marriage: IRC §401(a)(11) requires that a married participant's surviving spouse is the default beneficiary of a 401(k) or pension plan. To name someone other than the spouse, the spouse must provide written, notarized consent. This spousal consent requirement exists because Congress wanted to ensure retirement security for surviving spouses — it is a federal protection that cannot be waived by state law.

After divorce: the spousal consent requirement no longer applies because you are no longer married. You can submit a new beneficiary designation form naming anyone — children, a trust, a new partner, a charity — without your ex-spouse's signature. If a QDRO assigned a portion of the account to your ex-spouse as alternate payee, that portion is already legally your ex-spouse's money and is unaffected by the beneficiary designation change. The beneficiary update applies only to your remaining share.

Action: contact your plan administrator (HR department or the plan recordkeeper like Fidelity, Vanguard, or Schwab) and request a new beneficiary designation form. Complete and return it. Confirm in writing that the new designation is on file. Do this within 30 days of the divorce being finalized — there is no legal deadline, but every day of delay is a day your ex-spouse is the named beneficiary on a federally protected account.

2. IRAs (Traditional, Roth, SEP, SIMPLE)

Governing law: IRC §408 (federal tax law), but IRAs are not ERISA-governed plans because they are individual accounts, not employer-sponsored plans. This means state law is not preempted in the same way.

Rule: the beneficiary designation form on file with the IRA custodian generally controls, but state revocation-on-divorce statutes may apply to IRAs because ERISA preemption does not reach them. In the approximately 28 states that follow UPC §2-804, a divorce may automatically revoke an ex-spouse's IRA beneficiary designation — but enforcement is inconsistent. Some IRA custodians honor state revocation statutes; others follow the designation form on file and let the parties litigate.

SECURE Act impact: if you name your adult children as IRA beneficiaries (the most common post-divorce choice), they are subject to the 10-year distribution rule under the SECURE Act. A $500,000 IRA inherited by two children requires full distribution within 10 years — roughly $25,000 per year per child in mandatory withdrawals, taxed as ordinary income. For children in their peak earning years, this can push them into the 32% or 35% marginal bracket. Consider whether a Roth conversion of some IRA assets before naming new beneficiaries makes sense — the conversion triggers tax now at your rate, but distributions to your children from an inherited Roth IRA within the 10-year window are tax-free.

Action: contact your IRA custodian and submit a new beneficiary designation. Do not rely on state revocation-on-divorce statutes, even if your state has one.

3. Life insurance policies

Governing law: state insurance law — unless the policy is an employer-provided group policy governed by ERISA (many employer group life policies are ERISA plans).

Rule for non-ERISA policies (individual policies, policies owned outside of employment): state revocation-on-divorce statutes apply in approximately 28 states. In those states, the divorce automatically revokes the ex-spouse's designation, and the proceeds pass to contingent beneficiaries or the estate. However, many divorce settlements require one or both spouses to maintain life insurance naming the ex-spouse as beneficiary to secure alimony or child support obligations — this contractual obligation overrides the automatic revocation.

Rule for ERISA policies (employer group life): ERISA preempts state law, and Egelhoff applies. The named beneficiary on the plan form controls. Update it.

Dollar stakes: life insurance is often the largest single beneficiary-designation asset. A $750,000 term policy with an ex-spouse still named as beneficiary will pay $750,000 to that ex-spouse. Your children, your estate, and your divorce decree are all irrelevant if the form says otherwise.

Action: for individual policies, contact the insurance carrier. For employer group policies, contact HR. For policies required by the divorce decree to name the ex-spouse, confirm the obligation and coverage amount — and set a calendar reminder to update the beneficiary when the obligation terminates (e.g., when alimony ends or the youngest child turns 18).

4. Wills, trusts, and transfer-on-death registrations

Governing law: state probate and trust law.

Revocation-on-divorce statutes: in states following UPC §2-804, a divorce automatically revokes any provision in a will or revocable trust that benefits the ex-spouse. The will is read as if the ex-spouse predeceased the testator. This is a safety net — but it only works in states that have adopted this rule, and it does not apply to irrevocable trusts.

Transfer-on-death (TOD) and payable-on-death (POD) registrations: brokerage accounts, bank accounts, and real property (in states allowing TOD deeds) can have beneficiary designations that pass assets outside of probate. These are governed by state law, and revocation-on-divorce statutes generally apply — but again, do not rely on automatic revocation. Update them explicitly.

Action: execute a new will. If you have a revocable trust, amend or restate it. Update all TOD and POD designations on brokerage and bank accounts. Review any irrevocable trusts (irrevocable life insurance trusts, GRATs, etc.) with an estate planning attorney — these may not be modifiable without court action or the consent of all beneficiaries.

Community property states: additional complexity

In the 9 community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin), beneficiary designations interact with the community property presumption in ways that do not arise in equitable-distribution states.

During the marriage, community property retirement accounts are presumed to be owned 50/50 by both spouses — regardless of whose name is on the account. ERISA's spousal consent requirement under IRC §401(a)(11) reinforces this: you cannot remove your spouse as 401(k) beneficiary during the marriage without the spouse's written, notarized consent.

After divorce, the community property interest has been divided (ideally by QDRO for employer plans, or by transfer incident to divorce for IRAs under IRC §408(d)(6)). But if the QDRO was never filed — or if it was filed but the beneficiary designation was never updated — the ex-spouse may retain both a community property claim and a beneficiary designation claim. In community property states, this creates a double-exposure scenario that does not exist in equitable-distribution states: the ex-spouse may argue entitlement under both the community property regime and the plan beneficiary form.

Worked example: the cost of one missed update

David and Maria divorce in Texas after 22 years of marriage. Their settlement divides $1.6M in marital assets. David retains:

• His 401(k): $480,000 (after Maria's share was transferred via QDRO)
• A $750,000 term life insurance policy through his employer (ERISA-governed group plan)
• A Traditional IRA: $220,000 (rollover from a prior employer plan)
• A brokerage account with TOD designation: $150,000

David updates the beneficiary on his 401(k), IRA, and brokerage TOD — naming his two adult children, ages 24 and 26, as equal beneficiaries. He forgets to update the employer group life insurance policy. Maria is still the named beneficiary.

Three years later, David dies unexpectedly. His children receive the 401(k) ($480,000), the IRA ($220,000), and the brokerage account ($150,000) — a total of $850,000. But the $750,000 life insurance policy pays to Maria because she is the named beneficiary on the ERISA-governed plan form.

David's children sue, arguing that the divorce decree awarded the policy to David and that Texas's revocation-on-divorce statute (Texas Family Code §9.301) should apply. The court follows Egelhoff: ERISA preempts the Texas statute. The plan form controls. Maria receives $750,000.

The tax layer adds insult: the 401(k) and IRA inherited by David's children are subject to the SECURE Act's 10-year rule. The children must withdraw $700,000 from tax-deferred accounts over 10 years — $70,000 per year combined, taxed as ordinary income. At a blended 24% federal rate plus 0% Texas state income tax, that is approximately $168,000 in total income tax on the inherited retirement accounts. Meanwhile, the $750,000 life insurance proceeds received by Maria are income-tax-free under IRC §101(a)(1).

Net result: David's children receive $850,000 in gross assets but owe approximately $168,000 in income tax over 10 years, netting roughly $682,000 in after-tax value. Maria receives $750,000 tax-free. One missed beneficiary designation form — a single page of paperwork — shifted $750,000 away from David's intended beneficiaries.

The 30-day post-divorce beneficiary checklist

Within 30 days of the divorce decree being entered, complete these steps. There is no legal requirement to act within 30 days — but every day of delay is unnecessary risk:

• Week 1: request new beneficiary designation forms from every employer plan administrator (401(k), 403(b), pension, group life insurance). Contact your IRA custodian(s). Contact each individual life insurance carrier.
• Week 2: complete and submit the forms. For 401(k) and pension plans, confirm that the QDRO has been processed and your ex-spouse's share has been transferred — do not update the beneficiary until the QDRO transfer is complete, or the new designation may apply to the full pre-transfer balance.
• Week 3: update TOD and POD registrations on brokerage and bank accounts. Execute a new will and update or restate your revocable trust. If you have an irrevocable trust, schedule a consultation with an estate planning attorney.
• Week 4: confirm in writing with every institution that the new designations are on file. Request written confirmation or access your account online to verify the updated beneficiary appears in the system. File these confirmations with your other estate planning documents.

If you remarry, ERISA's spousal consent rules re-engage: your new spouse automatically becomes the default beneficiary of your 401(k) and pension plan, and you will need the new spouse's notarized consent to name anyone else.

When not to remove the ex-spouse

Some divorce settlements intentionally require one or both ex-spouses to remain as beneficiaries on specific accounts:

• Life insurance securing alimony: if the divorce decree requires you to maintain a $500,000 life insurance policy with your ex-spouse as beneficiary to secure spousal support payments, removing the ex-spouse violates the court order. The obligation typically terminates when alimony ends (remarriage, cohabitation, death, or the specified termination date).
• Life insurance securing child support: similar to alimony — the policy ensures that child support obligations are funded if the paying spouse dies. The obligation usually terminates when the youngest child reaches the age of majority (18 or 21 depending on the state).
• QDRO-assigned retirement benefits: if a QDRO assigns a portion of your 401(k) to your ex-spouse, that portion belongs to your ex-spouse as alternate payee. You cannot override a QDRO by changing the beneficiary designation — the QDRO has independent legal force under ERISA §206(d)(3).

Review your divorce decree and settlement agreement carefully before making changes. Update everything you are permitted to update; leave untouched anything the decree requires you to maintain.

The ERISA preemption hierarchy: what overrides what

Understanding the legal hierarchy prevents costly assumptions:

• ERISA plan documents + beneficiary designation: override everything below for employer-sponsored plans. (Egelhoff v. Egelhoff, 532 U.S. 141 (2001))
• QDROs: override beneficiary designations for the specific portion of the account assigned to the alternate payee. (ERISA §206(d)(3), IRC §414(p))
• Divorce decree: binding between the spouses but does not bind the plan administrator. Cannot override an ERISA beneficiary designation.
• State revocation-on-divorce statute: applies to non-ERISA assets (individual life insurance, bank TOD/POD, wills, trusts, potentially IRAs) but is preempted by ERISA for employer plans.
• Will: governs only assets passing through probate. Does not override beneficiary designations on any account type.

The practical lesson: your will is the least powerful document in your estate plan. Beneficiary designations, QDROs, and plan documents all override it. After divorce, the beneficiary designation form — not the will, not the divorce decree — is the document that determines who receives your retirement accounts and life insurance proceeds.
