Mississippi law automatically revokes most ex-spouse beneficiary designations the moment a divorce is final under Miss. Code § 91-29-7, but this protection does NOT cover ERISA-governed 401(k)s, pensions, or employer life insurance. To change a beneficiary during divorce in Mississippi, file paperwork directly with each plan administrator — automatic revocation only applies to non-ERISA assets after the final decree.

Does Mississippi Automatically Remove an Ex-Spouse as Beneficiary?
Yes, Mississippi automatically revokes most ex-spouse beneficiary designations upon a final divorce judgment under Miss. Code § 91-29-7, enacted July 1, 2020. The dissolution of marriage revokes any revocable disposition to a former spouse made before the divorce. This covers wills, trusts, transfer-on-death deeds, payable-on-death bank accounts, and many beneficiary designations made under state law.
Mississippi joined roughly 26 states with revocation-upon-divorce statutes when the Legislature passed Senate Bill 2851 in 2020. Before that reform, Mississippi had no comprehensive automatic-revocation rule, leaving ex-spouses on policies indefinitely. Under Miss. Code § 91-29-5, a "divorced individual" means a person whose marriage was dissolved by divorce, annulment, or a declaration that the marriage is void. The statute treats the former spouse as if they predeceased the divorced individual, redirecting assets to contingent beneficiaries. Two critical limitations apply: the law only covers designations made BEFORE the divorce, and a subsequent remarriage to the same person undoes the revocation entirely. Federal ERISA plans remain a major exception, discussed below.
Why ERISA 401(k) Beneficiary Changes Require Direct Action
Mississippi's automatic revocation statute does NOT apply to 401(k) accounts, pensions, or employer-provided life insurance because federal ERISA law preempts state revocation statutes. The plan administrator pays whoever is named on the form on file, regardless of divorce. If you do not submit a new 401(k) beneficiary divorce form, your ex-spouse will likely receive the entire account balance.
The U.S. Supreme Court settled this in Egelhoff v. Egelhoff, 532 U.S. 141 (2001), holding that ERISA preempts state automatic-revocation statutes. The Court ruled administrators must follow "the documents and instruments governing the plan," not state law. In that case, the participant divorced, died two months later without updating his Boeing pension and life insurance forms, and his ex-wife collected both. In Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009), the Court confirmed that even a waiver written into a divorce decree does not override the beneficiary form — only filing a new form does. For any 401(k) beneficiary divorce update, request the change-of-beneficiary form directly from your plan administrator and submit it. Note that ERISA requires written spousal consent before you can name anyone other than your current spouse as primary 401(k) beneficiary, so timing relative to your final decree matters.
How a QDRO Differs From a Beneficiary Change
A Qualified Domestic Relations Order (QDRO) divides retirement assets between spouses during divorce, but it does NOT automatically remove your ex-spouse as the death beneficiary. These are two separate legal actions. Even after a QDRO splits a 401(k) 50/50, the death-beneficiary line still names whoever appears on the plan's beneficiary form.
This distinction causes some of the most expensive divorce mistakes. A QDRO is a court order recognizing a former spouse's right to a portion of retirement benefits accrued under an ERISA plan. It assigns a present-value share of the account. The death beneficiary, by contrast, controls who receives the remaining balance if the participant dies. Family law attorneys regularly report six-figure 401(k) balances paid to ex-spouses who had not spoken to the participant in years, simply because the beneficiary form was never changed. To fully protect your retirement assets in a Mississippi divorce, you need both: (1) a QDRO to divide the account if the decree requires it, and (2) a new beneficiary designation filed with the plan administrator. The QDRO handles division; only the new form handles inheritance. Treat the IRA beneficiary divorce update separately too, since IRAs follow different custodian rules than employer 401(k)s.
Can You Change Beneficiaries While the Divorce Is Pending?
Mississippi has no statewide automatic temporary restraining order (ATRO) freezing beneficiary changes during divorce, unlike California. However, a chancery court can issue a specific temporary injunction restricting changes, so you should verify whether one applies before acting. Without such an order, Mississippi spouses generally may change non-ERISA beneficiaries while the case is pending.
Unlike states such as California — where filing a divorce petition triggers automatic restraining orders prohibiting any change to insurance beneficiaries — Mississippi imposes no such automatic financial freeze. The "restraining orders" referenced in Mississippi statute, Miss. Code § 93-21-15, address domestic abuse protection, not financial or beneficiary restrictions, and last only 10 to 20 days. That said, chancery courts can issue temporary orders restricting asset transfers when a party requests one. Before changing any beneficiary mid-divorce, confirm with your attorney whether your specific chancery court district has entered a standing or temporary order. Changing an ERISA 401(k) beneficiary while married also typically requires spousal consent until the divorce is final. For a life insurance beneficiary divorce change on a private policy, contact the insurer directly, but document the change and keep your attorney informed to avoid violating any pending court directive.
Step-by-Step: Updating Each Beneficiary Type in Mississippi
Updating beneficiaries in a Mississippi divorce requires contacting each financial institution separately because no single form covers all assets. Plan to update at least six categories: life insurance, 401(k)/pension, IRA, bank accounts, your will, and any transfer-on-death deeds. Each has a distinct process and timeline ranging from same-day to several weeks.
Follow this sequence after your divorce is final:
- Life insurance (private policies): Request a change-of-beneficiary form from your insurer. Private life insurance beneficiary divorce changes are governed by state law and may be auto-revoked under § 91-29-7, but file a new form anyway for certainty.
- 401(k) and employer pension: Obtain the ERISA change form from your plan administrator. These are NOT auto-revoked. Confirm whether spousal consent is still required.
- IRA accounts: Submit a new beneficiary form to your IRA custodian. IRA beneficiary divorce rules vary by custodian; some impose their own consent rules.
- Bank accounts (POD/TOD): Update payable-on-death and transfer-on-death designations at your bank. A bank account beneficiary divorce change typically takes effect immediately.
- Will and trusts: Execute a new will or codicil. While § 91-29-7 revokes ex-spouse provisions, a fresh document prevents disputes.
- Transfer-on-death deeds: Under Miss. Code § 91-27-21, divorce revokes a TOD deed naming the former spouse, but recording a new deed confirms your intent.
Mississippi Divorce Cost and Filing Overview
Filing for divorce in Mississippi costs $148 for a no-fault (irreconcilable differences) case and $158 for a fault-based case, though fees vary by county and commonly range $150-$200. Mississippi is among the most affordable states for filing — California charges $435 and Florida charges $409 by comparison. You file in chancery court, which operates in all 82 counties.
As of March 2026, verify current fees with your local chancery clerk before filing. Mississippi has 82 chancery courts handling all divorce matters. Under Miss. Code § 93-5-5, at least one spouse must have been a bona fide Mississippi resident for six months before filing. The statute strictly bars forum-shopping: if a party acquired residence solely to secure a divorce, the court dismisses the complaint at the filing party's cost. Mississippi is unusual in requiring mutual consent for no-fault divorce — if your spouse refuses to cooperate, you must pursue one of the 12 fault grounds or wait. The 60-day waiting period under Miss. Code § 93-5-2 applies to irreconcilable differences cases, meaning the complaint must be on file 60 days before a hearing. If you cannot afford the fee, file a Motion to Proceed In Forma Pauperis with a Pauper's Affidavit to request a waiver.
Common Beneficiary Mistakes That Cost Mississippi Families
The most expensive beneficiary mistake in a Mississippi divorce is assuming the automatic revocation statute covers everything — it does not cover ERISA 401(k)s, pensions, or employer life insurance. A second costly error is believing a QDRO removes the ex-spouse as death beneficiary. Both mistakes have sent six-figure sums to unintended recipients.
Mississippi families repeatedly make several avoidable errors. First, they rely entirely on Miss. Code § 91-29-7 and never update employer-plan forms, leaving ex-spouses on 401(k)s the statute cannot touch. Second, they confuse account division (QDRO) with death-beneficiary designation, treating one as if it accomplishes both. Third, they forget that remarriage to the former spouse automatically undoes the revocation, restoring the ex as beneficiary. Fourth, they overlook contingent beneficiaries — if you named your spouse as primary and your sister as contingent, revocation may redirect assets to your sister, which may or may not match your post-divorce wishes. Fifth, they fail to update IRA beneficiary divorce designations, wrongly assuming IRAs follow the same rules as 401(k)s. The reliable fix for all six categories is direct action: file new forms with every institution and execute a new will after your divorce is final.
