In Missouri, divorce automatically revokes most beneficiary designations naming your former spouse under Mo. Rev. Stat. § 461.051, effective the date your dissolution judgment is entered. However, ERISA-governed 401(k)s and employer life insurance are preempted by federal law, so you must manually change those designations directly with the plan administrator to make the change legally binding.

What Does Missouri Law Say About Changing Beneficiaries After Divorce?
Missouri law automatically revokes any beneficiary designation in favor of your former spouse when your divorce is finalized, under Mo. Rev. Stat. § 461.051. This automatic revocation took effect on the dissolution date and applies to nonprobate transfers, including transfer-on-death accounts, payable-on-death bank accounts, and TOD deeds, whether or not the designation mentions marital status.
The statute treats the revoked provision as if the former spouse had disclaimed it, meaning the asset passes to your contingent beneficiary or your estate. This automatic protection also extends to relatives of your former spouse, so a designation naming your ex's sibling or parent is revoked along with the spouse's designation. The revocation applies only at dissolution, not during the pending divorce, which is a critical distinction. To change a beneficiary divorce Missouri residents must understand that the statute does not cover every asset class equally, and federal preemption creates major exceptions for employer-sponsored plans that override Missouri law entirely.
Which Assets Are Automatically Revoked vs. Which Require Manual Changes?
Missouri's automatic revocation under Mo. Rev. Stat. § 461.051 covers most state-governed nonprobate assets, but ERISA-governed accounts like 401(k)s, pensions, and employer life insurance are exempt because federal law preempts the state statute. For those assets, the plan administrator must pay the named beneficiary even if that person is your ex-spouse.
This distinction matters enormously. The U.S. Supreme Court ruled in Egelhoff v. Egelhoff, 532 U.S. 141 (2001), that ERISA preempts state revocation statutes for employer-sponsored plans. In Kennedy v. DuPont, 555 U.S. 285 (2009), the Court confirmed that plan administrators must follow the beneficiary form on file, not a divorce decree. The table below shows how different assets are treated for a 401k beneficiary divorce, life insurance beneficiary divorce, and bank account beneficiary divorce in Missouri.
| Asset Type | Auto-Revoked Under § 461.051? | Action Required |
|---|---|---|
| Employer 401(k) / pension (ERISA) | No — federally preempted | Submit new beneficiary form to plan administrator |
| Employer group life insurance (ERISA) | No — federally preempted | Submit new beneficiary form to plan administrator |
| Individual IRA (non-ERISA) | Yes, generally | Confirm with custodian; file new form to be safe |
| Private life insurance policy | Yes, generally | File new designation with insurer |
| Payable-on-death bank account | Yes | Update with bank to be safe |
| Transfer-on-death investment account | Yes | Update with brokerage |
| Transfer-on-death deed | Yes | Record new deed or revocation |
How Does ERISA Override Missouri's Beneficiary Revocation Statute?
ERISA, the federal Employee Retirement Income Security Act, requires plan administrators to pay benefits to the beneficiary named in plan documents, completely overriding Missouri's automatic revocation statute for a 401k beneficiary divorce. The Supreme Court established this rule in two cases, holding that the named form controls regardless of divorce or state law.
In Egelhoff v. Egelhoff, 532 U.S. 141 (2001), David Egelhoff divorced but failed to remove his ex-wife from his Boeing pension and life insurance. He died weeks later, and the Court ruled ERISA preempted Washington's revocation statute, paying the ex-wife. In Kennedy v. DuPont, 555 U.S. 285 (2009), the Court ruled that even a divorce decree waiving retirement benefits could not override the plan's beneficiary form. The practical lesson is unambiguous: for any employer-sponsored plan, you must submit a new beneficiary designation directly to the plan administrator. Relying on Missouri's § 461.051 revocation or your divorce decree will fail, and your ex-spouse will collect the money. This is the single most common and costly mistake in divorce beneficiary planning.
Can You Change Beneficiaries While a Missouri Divorce Is Pending?
During a pending Missouri divorce, either spouse generally remains free to change beneficiary designations unless a court issues a restraining order under Mo. Rev. Stat. § 452.315. Missouri has no automatic statewide restraining order that triggers at filing, so protection requires an affirmative motion with a supporting affidavit demonstrating irreparable injury.
This is a significant gap that surprises many divorcing spouses. Unlike California, which imposes Automatic Temporary Restraining Orders the moment a petition is served, Missouri requires you to file a motion under § 452.315 to prevent your spouse from transferring assets or changing beneficiaries. The court may issue the order, including ex parte relief, if it finds irreparable injury would result. The restraining order terminates when final judgment is entered or the petition is voluntarily dismissed. Missouri also separately prohibits terminating certain insurance under Mo. Rev. Stat. § 452.317. If you worry your spouse may remove you as beneficiary of a life insurance beneficiary divorce policy or drain a bank account beneficiary divorce designation, ask your attorney to seek a restraining order early in the case.
What Happens to Life Insurance Beneficiaries in a Missouri Divorce?
For a private life insurance beneficiary divorce in Missouri, Mo. Rev. Stat. § 461.051 automatically revokes a designation naming your former spouse on the dissolution date. However, employer-provided group life insurance governed by ERISA is exempt, so you must file a new beneficiary form with the plan administrator to remove your ex.
Missouri divorce courts also frequently order one spouse to maintain a life insurance policy naming the children or the other spouse as security for child support or maintenance obligations. If your settlement or judgment requires you to keep an ex-spouse as beneficiary for support purposes, that court-ordered designation overrides the automatic revocation. Read your dissolution judgment carefully. For private term or whole-life policies you personally own, contact your insurer directly to submit a new beneficiary form even though the law revokes the ex automatically, because insurers process claims based on the form on file and a clean updated record prevents costly delays, interpleader actions, or litigation after your death. Always keep dated copies confirming the insurer received and recorded your change.
How Do You Change a 401(k) or IRA Beneficiary in a Missouri Divorce?
To change a 401(k) beneficiary in a Missouri divorce, you must submit a new designation form directly to your plan administrator, because ERISA preempts Missouri's automatic revocation statute. For an IRA beneficiary divorce, contact your IRA custodian to file a new form, since individual IRAs are typically not ERISA plans and are subject to Missouri revocation.
The distinction between employer plans and individual retirement accounts is crucial. Employer 401(k)s and pensions are ERISA-governed, so the named beneficiary controls regardless of divorce. Individual IRAs you opened independently are generally not ERISA plans, so Missouri's § 461.051 revocation should apply, but custodian practices vary and many follow the form on file. To avoid any ambiguity in an IRA beneficiary divorce, file a fresh designation form with every custodian. If your divorce settlement awards a portion of a 401(k) or pension to your ex-spouse, that transfer requires a Qualified Domestic Relations Order (QDRO), a separate court order that directs the plan to pay an alternate payee. A QDRO is distinct from a beneficiary change and must satisfy specific federal requirements to be valid.
What Is the Process and Cost to File for Divorce in Missouri?
Filing for divorce in Missouri costs between $130 and $250 depending on your county, with at least one spouse meeting the 90-day residency requirement under Mo. Rev. Stat. § 452.305. A mandatory 30-day waiting period applies from filing to judgment, and Missouri is a no-fault state requiring only that the marriage is irretrievably broken.
Filing fees vary across Missouri's 45 judicial circuits. St. Louis County charges approximately $140, while Jackson County charges around $177.50. Counties with minor children typically add $75 to $100. Jefferson County, for example, charges $131 without children and $231 with children. As of June 2026, verify the exact fee with your local circuit clerk before filing, because each circuit sets its own schedule. Low-income filers may request a fee waiver by filing a Motion and Affidavit in Support of Request to Proceed as a Poor Person; judges generally grant waivers for incomes near or below 125% of the federal poverty level. Uncontested divorces typically finalize in 45 to 90 days, while contested cases involving property, custody, or support disputes may take 6 to 18 months.
What Steps Should You Take to Update Beneficiaries After a Missouri Divorce?
After a Missouri divorce, immediately submit new beneficiary forms for all ERISA-governed assets, confirm Missouri's automatic revocation under Mo. Rev. Stat. § 461.051 applies to your other accounts, and update your estate planning documents. Acting within 30 days of your dissolution judgment prevents your ex-spouse from inadvertently collecting assets.
Follow this checklist to protect your assets comprehensively:
- Contact every employer 401(k), pension, and group life insurance plan administrator and file new beneficiary forms in writing.
- File new designations for private life insurance policies, even though the law revokes the ex automatically.
- Update IRA beneficiary forms with every custodian to eliminate ambiguity.
- Update payable-on-death bank accounts and transfer-on-death brokerage accounts.
- Record a new transfer-on-death deed if you previously named your spouse.
- Revise your will, revocable trust, and powers of attorney with a Missouri estate attorney.
- Review any court-ordered beneficiary requirements in your dissolution judgment for support security.
- Keep dated confirmations from each institution proving your changes were received and recorded.
Missouri's automatic revocation protects you in many cases, but relying on it alone leaves dangerous gaps with ERISA assets, court-ordered designations, and institutions that follow the form on file. A complete manual update is the only reliable strategy.
