When you change beneficiary divorce Iowa rules apply, Iowa Code §598.20A and §598.20B automatically revoke an ex-spouse as beneficiary on life insurance policies, IRAs, payable-on-death accounts, and annuities upon the dissolution decree. However, federal ERISA law preempts these statutes for employer-sponsored 401(k) plans, where the named beneficiary on plan documents controls regardless of divorce. The Iowa divorce filing fee is $265.
Divorce in Iowa does not automatically protect every account you own from passing to your ex-spouse. Iowa's revocation-on-divorce statutes cover some assets automatically, but leave dangerous gaps for the most valuable accounts most people hold: their employer 401(k) and pension. This guide explains exactly which beneficiary designations Iowa law revokes for you, which ones you must change yourself, and the precise steps to protect your life insurance, retirement accounts, and bank accounts during and after an Iowa dissolution of marriage.

Does Iowa Automatically Remove My Ex-Spouse as a Beneficiary After Divorce?
Iowa automatically removes your ex-spouse as beneficiary on life insurance policies, IRAs, annuities, and payable-on-death accounts the moment your dissolution decree is entered, under Iowa Code §598.20A and §598.20B. However, this automatic revocation does NOT apply to employer-sponsored 401(k) plans, pensions, or other ERISA-governed accounts, which require federal-law steps to change.
This split is the single most important fact in Iowa beneficiary law. Iowa Code §598.20A voids any designation naming your former spouse or their relatives as a life insurance beneficiary upon a decree of dissolution, annulment, or separate maintenance. Iowa Code §598.20B, enacted by 2007 Iowa Acts ch. 134 §5, extends the same automatic revocation to individual retirement accounts, stock option plans, transfer-on-death accounts, payable-on-death accounts, and annuities. When a designation is voided, the proceeds pass to the alternate beneficiary, or if none exists, to your estate. Both statutes open with the critical qualifier "except as preempted by federal law" — the gateway through which 401(k) plans escape Iowa's protection.
Why Iowa's Automatic Revocation Does Not Protect Your 401(k)
Iowa's automatic revocation statutes do not protect your 401(k), employer pension, or group life insurance because the federal Employee Retirement Income Security Act of 1974 (ERISA) preempts state revocation laws. Under the U.S. Supreme Court ruling in Egelhoff v. Egelhoff, 532 U.S. 141 (2001), a 401(k) plan administrator must pay the named beneficiary on plan documents even after divorce.
In Egelhoff, the Supreme Court struck down a Washington statute nearly identical to Iowa's §598.20A and §598.20B, holding that ERISA's requirement to administer plans "in accordance with the documents and instruments governing the plan" overrides any state law that automatically revokes a beneficiary. The Court reinforced this in Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009), establishing the "plan documents rule": even a divorce decree in which your ex-spouse explicitly waives all rights to your retirement plan is insufficient. The administrator pays whoever is named on the form. The practical consequence is severe: if you divorce in Iowa but never submit a new beneficiary form to your 401(k) provider, your ex-spouse will legally collect that account when you die, no matter what your decree says.
The Two Exceptions: When ERISA Beneficiaries Actually Change
There are only two reliable ways to change an ERISA-governed beneficiary after an Iowa divorce: file a new beneficiary designation form directly with the plan administrator, or obtain a Qualified Domestic Relations Order (QDRO) as part of your divorce. A QDRO is a specialized court order that ERISA recognizes as a valid exception to the plan documents rule.
The QDRO is the only court mechanism that ERISA accepts for redirecting retirement benefits at divorce. A divorce decree alone — even one stating your spouse waives all interest — does not qualify; the order must contain the specific, objective criteria ERISA requires (the plan name, the participant and alternate payee, and the precise amount or percentage assigned). For dividing a 401(k) or pension between spouses, the QDRO assigns a portion to the ex-spouse as an "alternate payee." For removing an ex-spouse as your death beneficiary going forward, the more reliable step is simply submitting a fresh beneficiary designation form to the plan after the decree. Most plan administrators provide this form online or by mail; the change takes effect once the administrator accepts and records it, not when you sign it.
Changing Your Life Insurance Beneficiary in an Iowa Divorce
Under Iowa Code §598.20A, an individually owned life insurance policy naming your ex-spouse is automatically voided when the dissolution decree is entered, redirecting proceeds to your alternate beneficiary or estate. However, employer-provided group life insurance governed by ERISA is NOT automatically revoked and requires a new beneficiary form filed with the plan administrator.
This distinction trips up thousands of divorced Iowans. A policy you bought yourself from a private insurer falls squarely under §598.20A — the ex-spouse designation dies with the decree. But the life insurance most working Iowans actually carry is group coverage through an employer, which is an ERISA plan. For that policy, life insurance beneficiary divorce protection comes only from filing a new designation form, exactly as with a 401(k). The statute also preserves designations the decree itself orders: if your Iowa divorce decree requires you to maintain life insurance naming your ex-spouse (common when alimony or child support obligations exist), §598.20A honors that court-ordered designation rather than voiding it. Always check whether your decree imposes a life-insurance obligation before assuming the named ex-spouse is removed.
Bank Accounts, POD Designations, and Joint Ownership
Iowa Code §598.20B automatically revokes your ex-spouse as a payable-on-death (POD) or transfer-on-death (TOD) beneficiary on bank and brokerage accounts once the decree is entered. However, joint accounts with right of survivorship are NOT covered by this revocation statute and must be retitled or closed separately during the divorce.
The POD and TOD revocation under §598.20B handles death-beneficiary designations cleanly, but it does nothing about ownership. Bank account beneficiary divorce planning therefore has two separate tasks. First, the death designation: if you named your spouse as POD beneficiary on a checking, savings, or brokerage account, the decree voids that automatically — though updating the form yourself avoids any dispute with the institution. Second, ownership: a jointly held account with right of survivorship is a current-ownership arrangement, not a beneficiary designation, so §598.20B does not touch it. Either spouse can typically withdraw the full balance of a joint account at any time. During an Iowa divorce, joint accounts should be addressed in the property settlement, then closed or retitled to a single owner once the court divides the funds equitably under §598.21.
IRA and 401(k) Beneficiaries: The Critical Difference
Iowa Code §598.20B automatically revokes an ex-spouse as beneficiary on a traditional or Roth IRA upon divorce, but the same protection does NOT extend to a 401(k), which is an ERISA plan governed by federal law. This means IRA beneficiary divorce protection is automatic in Iowa, while 401(k) beneficiary divorce protection requires affirmative action.
The IRA-versus-401(k) divide confuses even careful planners because both are "retirement accounts." The legal difference is the source of governing law. An IRA is a personal account established under the Internal Revenue Code and falls within §598.20B's list of covered instruments — the Iowa decree automatically voids an ex-spouse designation. A 401(k), 403(b), or defined-benefit pension is an employer-sponsored ERISA plan, and under Egelhoff and Kennedy, Iowa's revocation statute is preempted. For your IRA, the law removes your ex-spouse for you; for your 401(k) beneficiary divorce situation, you must file a new designation form with the plan or secure a QDRO. The safest universal rule: treat every retirement account as if Iowa law does nothing, and affirmatively re-file every beneficiary designation after your decree.
Wills, Trusts, and Powers of Attorney After an Iowa Divorce
Iowa Code §633.271 automatically revokes any provision in your will that names your ex-spouse as a beneficiary or appoints them as executor or trustee upon divorce. Separately, Iowa Code §633B.10 terminates a former spouse's financial power of attorney when the dissolution petition is filed, and §144B.12 revokes their medical power of attorney upon divorce.
Iowa's estate-planning revocation rules are broader than the beneficiary statutes but still leave gaps. Under §633.271, divorce treats your ex-spouse as having predeceased you for purposes of your will, nullifying gifts and fiduciary appointments to them. The financial power of attorney terminates earlier than most people realize — under §633B.10, it ends when the petition is filed, not when the decree is entered, removing your spouse's authority over your finances during the divorce itself. The medical power of attorney under §144B.12 ends at the decree. Revocable living trusts, however, are not clearly covered by these automatic-revocation statutes, so trust provisions naming an ex-spouse should be amended directly. Iowa attorneys uniformly advise updating all estate documents after divorce rather than relying solely on automatic revocation, because federal preemption and document-specific gaps can still leave an ex-spouse in control.
Step-by-Step: Updating Beneficiaries During Your Iowa Divorce
To fully protect your assets in an Iowa divorce, contact each financial institution directly and file a new beneficiary designation form for every account, rather than relying on Iowa Code §598.20A or §598.20B. The dissolution decree takes a minimum of 90 days from service under Iowa Code §598.19, giving you time to inventory and update accounts.
Follow this sequence to close every gap left by Iowa's partial automatic revocation:
- Inventory every account with a beneficiary: life insurance (private and group), 401(k)/403(b), pension, IRA, Roth IRA, HSA, annuities, POD bank accounts, and TOD brokerage accounts.
- Request a current beneficiary designation form from each institution and confirm who is presently named.
- For ERISA plans (401(k), pension, group life), understand that you may need spousal consent to change a beneficiary while still legally married — many plans require the current spouse's notarized consent until the divorce is final.
- After the decree is entered, immediately file new beneficiary forms naming your chosen replacement (children, trust, or other person).
- Address 401(k) and pension division through a QDRO drafted as part of the decree, then re-designate the death beneficiary.
- Retitle or close joint accounts under the property settlement governed by §598.21.
- Update your will, trust, and powers of attorney with an Iowa estate attorney.
Iowa Divorce Filing Basics: Fees, Residency, and Timeline
The Iowa divorce filing fee is $265 under Iowa Code §602.8105, paid electronically when filing the Petition for Dissolution of Marriage. Iowa requires the petitioner to have resided in the state for one year unless the respondent is personally served in Iowa, and imposes a mandatory 90-day waiting period from service before a decree can be entered.
Iowa is a no-fault divorce state. The only ground under Iowa Code §598.17 is that the marriage has suffered an "irretrievable breakdown" with no reasonable likelihood of preservation. The $265 fee set by §602.8105 applies whether your case is contested or uncontested, and is filed through Iowa's mandatory eFiling system. Expect additional costs: service of process is typically under $100, mediation runs roughly $200–$250 per party where required, and parenting classes for cases with children cost approximately $25–$75 per parent. If you cannot afford the fee, file Form 109 (no children) or Form 209 (with children) — the Application to Defer Payment of Costs — and a judge may waive prepayment. The 90-day waiting period under §598.19 runs from the date of service, not filing, and can extend to roughly 150 days if conciliation is ordered under §598.16. As of January 2026, the $265 fee is current — verify with your local clerk of court.
