Updating Your Will and Estate Plan After Divorce in Mississippi: Complete 2026 Guide

Mississippi automatically revokes provisions benefiting a former spouse in wills and trusts under Miss. Code Ann. § 91-29-1, enacted July 1, 2020. However, this automatic revocation does not apply to ERISA-governed employer benefits, which require manual beneficiary changes within 30 days of divorce finalization. Estate planning after divorce Mississippi requires updating at least 7-12 separate documents to ensure your assets pass to intended beneficiaries, protect minor children through proper guardianship designations, and prevent your former spouse from retaining control over healthcare or financial decisions.

Key Facts: Mississippi Estate Planning After Divorce

How Mississippi's Revocation Upon Divorce Statute Works

Mississippi's automatic revocation law treats your former spouse as having predeceased you for purposes of all estate planning documents executed before divorce. Under Miss. Code Ann. § 91-29-1, when a testator's marriage is dissolved by divorce, annulled, or declared void, all provisions in the will benefiting the former spouse are revoked by operation of law, including fiduciary appointments naming the former spouse as executor, trustee, or guardian. This statute applies to wills, revocable trusts, beneficiary designations on non-ERISA accounts, and powers of attorney executed before the divorce was finalized.

The revocation statute covers three primary categories under Miss. Code Ann. § 91-29-7. First, it revokes all revocable dispositions or appointments of property made to the former spouse. Second, it revokes any general or special power of appointment conferred on the former spouse. Third, it revokes any nomination of the former spouse to serve as personal representative, trustee, conservator, agent, or guardian. Mississippi also extends this revocation to relatives of the former spouse who are not your own relatives by blood or adoption.

Exceptions to Automatic Revocation

The automatic revocation does not apply in two circumstances specified by the statute. If the express terms of a trust instrument or will provide that the former spouse should remain a beneficiary despite divorce, the document controls over the automatic revocation. Additionally, if a contract relating to the division of the marital estate specifically requires that the former spouse remain a beneficiary, that agreement supersedes the revocation statute. This exception commonly appears in divorce settlement agreements where one spouse agrees to maintain life insurance naming the former spouse as beneficiary to secure alimony or child support obligations.

The revocation also does not apply if the former spouses remarry each other. Under Miss. Code Ann. § 91-29-9, a subsequent remarriage defeats the revocation and restores the former spouse's rights as though the divorce never occurred.

Joint Trusts and Division After Divorce

Mississippi law provides specific rules for handling joint revocable trusts created during marriage. Under the revocation upon divorce statute, a joint trust must be divided into two separate shares upon divorce. Each share consists of the respective former spouse's property contributions, and each share is subsequently disposed of as if the other former spouse had not survived the settlor. This means your half of the trust assets will pass according to your designated contingent beneficiaries rather than to your former spouse.

For joint trusts valued above $250,000, courts typically require formal trust division proceedings through the chancery court. The average cost for trust division ranges from $2,500 to $7,500 in attorney fees, depending on asset complexity. Trust assets must be properly retitled in the name of each spouse's separate successor trust, which requires coordination with financial institutions holding the underlying accounts.

Documents Requiring Manual Updates After Divorce

Despite Mississippi's automatic revocation statute, you must manually update several critical documents that fall outside the statute's protection. Relying solely on automatic revocation creates unnecessary ambiguity and potential litigation risk for your beneficiaries.

Wills and Codicils

Executing a new will within 30-60 days of divorce finalization eliminates any ambiguity about your testamentary intent. While the automatic revocation statute would treat your former spouse as having predeceased you, your will may not contain adequate contingent beneficiary provisions. If your original will left everything to your spouse without naming alternates, your estate would pass under Mississippi's intestacy laws to your children, parents, or siblings. A new will allows you to name specific beneficiaries, designate guardians for minor children, and appoint an executor who is not your former spouse.

Mississippi requires two witnesses for will execution under Miss. Code Ann. § 91-5-1. Notarization is not required but is recommended to create a self-proving will that expedites probate. The average cost for drafting a new will through a Mississippi attorney ranges from $300 to $800 for simple estates and $1,500 to $3,500 for estates involving trusts or complex asset structures.

Revocable Living Trusts

If you created a revocable living trust during marriage, you should amend or restate the entire trust document after divorce. Trust amendments typically cost $200 to $500, while a complete trust restatement ranges from $800 to $2,000. The amendment should remove your former spouse as beneficiary, trustee, and successor trustee. You must also update the trust to reflect any property division from the divorce, removing assets awarded to your former spouse and adding any new property you received.

Joint trusts require formal division as described above. Each spouse should create a new individual trust to hold their separate property. The successor trustee provisions are particularly important because the automatic revocation statute only removes your former spouse from fiduciary roles. You need to affirmatively name who will manage your trust if you become incapacitated or upon your death.

Healthcare Power of Attorney and Advance Directives

Mississippi automatically revokes your former spouse's authority under a healthcare power of attorney upon divorce. Under Miss. Code Ann. § 41-41-207, a decree of divorce, dissolution of marriage, or legal separation revokes a previous designation of a spouse as healthcare agent unless the divorce decree or the healthcare directive specifically provides otherwise.

However, you must execute a new healthcare power of attorney naming a replacement agent. Without a valid healthcare POA, Mississippi law designates a surrogate decision-maker in a specific priority order: guardian, spouse, adult child, parent, adult sibling, then any other adult who has exhibited special care and concern for the patient. After divorce, if you have no spouse and your adult children are unavailable, decisions may fall to your parents or siblings rather than the person you would actually prefer.

You may revoke a healthcare directive at any time by either a signed writing or by personally informing your supervising healthcare provider. However, oral revocation only removes treatment preferences. To remove your former spouse as healthcare agent, you must either execute a signed written revocation or directly inform the supervising healthcare provider.

Financial Power of Attorney

Unlike healthcare powers of attorney, Mississippi does not automatically revoke financial powers of attorney upon divorce. You must manually revoke any financial POA naming your former spouse. If you filed your original POA with the chancery clerk's office, you must file a written revocation with that same office under Miss. Code Ann. §§ 87-3-17, 87-3-107, and 87-3-111.

Provide written notice of revocation to any financial institutions, title companies, or other entities that may have copies of the original POA. Banks typically require both the revocation document and a new POA naming your replacement agent. The revocation should clearly identify the original POA by date and state that all authority granted thereunder is terminated.

ERISA Benefits: The Critical Exception to Automatic Revocation

Mississippi's automatic revocation statute does not apply to employer-sponsored retirement plans, life insurance, or other benefits governed by the federal Employee Retirement Income Security Act (ERISA). The U.S. Supreme Court ruled in Egelhoff v. Egelhoff (2001) that ERISA preempts state laws that automatically revoke a former spouse's beneficiary status. This means plan administrators must pay benefits to the named beneficiary on file, even if that beneficiary is your former spouse whom you divorced years ago.

Employer Life Insurance

For employer-provided group life insurance under ERISA, divorce alone does not change your beneficiary designation. You must submit a new beneficiary designation form to your employer's HR department or plan administrator. Without this change, your former spouse will receive the life insurance proceeds regardless of your divorce decree, any state automatic revocation laws, or even express provisions in your will leaving everything to someone else.

Many divorcing individuals assume their divorce decree waiving the former spouse's rights to benefits automatically changes the beneficiary designation. This assumption is legally incorrect for ERISA plans. Even if your divorce decree states that your former spouse waives all rights to your employer life insurance, the plan administrator must pay the named beneficiary on file. Your estate may have a claim against your former spouse for the proceeds, but the insurer will not redirect payment based on the divorce decree.

401(k), 403(b), and Pension Plans

Employer-sponsored retirement accounts require a Qualified Domestic Relations Order (QDRO) to divide the account in divorce and to change beneficiary designations. Under Miss. Code Ann. § 93-5-2 and federal ERISA requirements, a QDRO must contain at least 11 specific legal elements including the participant's name and address, the alternate payee's name and address, and the exact percentage or dollar amount to be distributed.

After your divorce is finalized and any QDRO has been processed, you must submit a new beneficiary designation form to your plan administrator. The QDRO only addresses division of account values. It does not automatically change your death beneficiary. Contact your HR department within 30 days of divorce finalization to request beneficiary change forms for all employer retirement accounts.

Mississippi PERS (Public Employees' Retirement System) covering state workers, teachers, and municipal employees requires a domestic relations order meeting both state law and plan-specific requirements. Contact PERS directly at 800-444-7377 for required forms.

IRAs and Non-ERISA Accounts

Individual Retirement Accounts (IRAs) are not governed by ERISA and may be subject to Mississippi's automatic revocation statute. However, to avoid ambiguity and potential delays in distribution, you should submit new beneficiary designation forms to your IRA custodian after divorce. IRAs transfer between spouses during divorce under IRC § 408(d)(6) as a transfer incident to divorce, which does not require a QDRO.

Retirement Account Beneficiary Change Checklist

Guardian Designations for Minor Children

Divorce often changes guardianship considerations for minor children. Your will should name a guardian to care for your children if you die while they are still minors. In Mississippi, the chancery court has exclusive jurisdiction over guardianship appointments and is not legally bound by your will's designation. However, courts give significant weight to parental preferences expressed in properly executed wills.

After divorce, the surviving parent typically retains custody unless there are grounds to appoint a third-party guardian. You should still name a guardian in your will for two scenarios: if both parents die simultaneously, or if the surviving parent is unable or unwilling to care for the children. Common reasons for naming a non-parent guardian include concerns about the other parent's substance abuse, history of abuse or neglect, or unstable living situation.

Mississippi law provides that if the guardianship involves a minor child, immediate preference is usually given to the parent unless the court appoints another person who is more qualified. If there has been evidence of abuse or neglect from either parent within a home, preference will usually be given to another guardian. You may petition for guardianship through the chancery court in the county where the child resides.

Successor Guardian Provisions

Your will should name both a primary guardian and one or two successor guardians in case your first choice cannot serve. Include a brief statement explaining your choices and explicitly stating that your former spouse should not serve as guardian under any circumstances if that reflects your intent. While the court makes final guardianship determinations, documented reasoning supports your preferred appointment.

Life Insurance Policy Updates

Non-ERISA Individual Policies

For individual life insurance policies not provided through an employer, Mississippi's automatic revocation statute likely applies. However, insurance companies maintain their own beneficiary records and may dispute or delay payment if the beneficiary designation on file conflicts with the automatic revocation. To eliminate uncertainty, submit new beneficiary designation forms directly to each insurance company within 30 days of divorce.

Policies Required by Divorce Decree

Many divorce decrees require one or both spouses to maintain life insurance naming the former spouse as beneficiary to secure alimony or child support obligations. If your divorce decree contains such a requirement, you must maintain the policy and beneficiary designation as ordered. Failing to maintain required coverage may constitute contempt of court and could result in penalties including jail time, fines, or modification of support obligations.

Typical life insurance requirements in Mississippi divorce decrees include maintaining coverage equal to the present value of remaining support obligations, which decreases over time as payments are made. For example, if you owe $2,000 monthly in alimony for 10 years, you might be required to maintain approximately $200,000 in coverage initially, decreasing annually.

Transfer-on-Death and Payable-on-Death Accounts

Beneficiary designations on bank accounts (payable-on-death), brokerage accounts (transfer-on-death), and real property (transfer-on-death deeds) may or may not be covered by Mississippi's automatic revocation statute depending on how they are characterized. The safest approach is to update all TOD and POD designations after divorce.

Mississippi enacted the Uniform Real Property Transfer on Death Act, codified at Miss. Code Ann. §§ 91-27-1 through 91-27-31, allowing real property to pass outside probate through a transfer-on-death deed. Under Miss. Code Ann. § 91-27-27, a properly recorded TOD deed transfers property to the designated beneficiary upon the owner's death. If your former spouse is named as beneficiary on a TOD deed, you should record a new TOD deed naming a different beneficiary or record a revocation of the original deed.

Mississippi Probate Considerations

Updating your estate plan helps your beneficiaries avoid probate complications. Mississippi probate is administered through the state's chancery courts, which have exclusive jurisdiction over estate matters, wills, and executor appointments. Probate in Mississippi typically takes 6-12 months, with a mandatory 90-day creditor period.

Small Estate Threshold

Mississippi allows a small estate affidavit for estates with personal property valued at $75,000 or less, excluding liens and encumbrances. This threshold was raised from $50,000 by S.B. 2850, effective July 1, 2020. The small estate affidavit can be used 30 days after death and does not require a court filing. However, it applies to personal property only, not real estate.

If your estate exceeds $75,000 in personal property or includes real estate not covered by a transfer-on-death deed, full probate will be required. The probate petition filing fee is approximately $140. Executors must file an inventory within 90 days of receiving letters testamentary.

Muniment of Title

Mississippi offers a muniment of title proceeding when the primary asset is real property and all non-real-estate property is worth $10,000 or less. No executor is appointed, no creditor notice is required, and the court order acts as a deed substitute to transfer real estate. This option is only available when the decedent left a valid will.
