Estate Planning in Mississippi
Mississippi's estate planning rules are deceptively different from its neighbors. A will can be entirely revoked by the birth of a child, divorce doesn't automatically remove a former spouse from a will, and the surviving spouse receives only a child's equal share under intestacy — not the priority share most states provide. But Mississippi also offers the nation's shortest creditor claim period and a powerful muniment of title procedure that transfers real estate without full probate.

What most people don't know about Mississippi
In Mississippi, having a child after you make your will can revoke the entire document — not just reduce the shares of other beneficiaries. Under Mississippi Code § 91-5-3, if you had no child at the time you executed your will and your will doesn't provide for future children, the will is completely revoked if you later have a child or your spouse is pregnant at the time of your death. Your entire estate is then distributed under intestacy law, as if you never made a will at all. Most states simply give the after-born child an intestacy share while keeping the rest of the will intact. Mississippi wipes the slate clean. For new parents, this means the will they made before having children may no longer exist.

Plain English Rules
- •Having a child after making a will can revoke the ENTIRE will — if your will doesn't provide for future children and you later have one, Mississippi treats you as if you died without a will
- •The surviving spouse receives only a child's equal share under intestacy — if there are three children, the spouse gets one-fourth, not half or more like in most states
- •Mississippi is one of the few states that recognizes oral (nuncupative) wills — but only during 'last illness,' at the testator's residence, and limited to $100 in personal property unless proved by two witnesses
- •Divorce does NOT automatically revoke will provisions in favor of a former spouse — you must create a new will after divorce to remove your ex
- •Mississippi has the shortest creditor claim period in the nation at 90 days — estates can close faster than in almost any other state
- •No state estate tax or inheritance tax — only the federal estate tax applies to very large estates
What Actually Breaks
Will made before having children, with no provision for future children
Entire will is revoked when a child is born or the spouse is pregnant at death — estate distributes under intestacy as if no will exists
Divorce without making a new will
Former spouse still inherits under the will — Mississippi does NOT automatically revoke provisions for a former spouse upon divorce
Holographic will with some typed or pre-printed material
May be invalid — Mississippi requires the entire will to be in the testator's handwriting for a holographic will
Surviving spouse assumes they receive at least half the estate (intestacy)
With multiple children, the spouse receives only an equal child's share — if there are four children, the spouse gets only one-fifth
Creditors file claims after the 90-day window
Claims are barred — but the executor must have properly published notice; failure to publish notice leaves claims open
No advance directive before incapacity
Medical decisions fall to a statutory surrogate hierarchy; Mississippi requires specific health-care directive formalities
Elective share claimed by spouse with substantial own assets
The elective share is reduced by the value of the spouse's own separate estate — a spouse with significant assets may receive little or nothing additional
If This Is Your Situation
Married with children (intestacy)
Surviving spouse and each child receive equal shares — the spouse does NOT receive a priority or minimum share; with three children, the spouse gets one-fourth
Married with no children (intestacy)
Surviving spouse inherits the entire estate
Will made before having children
If the will doesn't provide for future children, the ENTIRE will is revoked when a child is born — estate passes under intestacy law
Estate primarily consists of real property with under $10,000 in other assets
Muniment of title available — no executor appointed, no creditor notice required; court order serves as deed substitute to transfer real estate
Spouse left out of will
Spouse can renounce the will and claim the elective share — equivalent to the intestacy share, capped at one-half, minus the spouse's own separate estate
Small estate under $75,000
Small estate affidavit available — simplified procedure to transfer assets without full administration
Divorced but didn't update will
Former spouse still inherits — Mississippi does NOT automatically revoke will provisions upon divorce; a new will is required

How Mississippi Actually Works
Mississippi does not follow the Uniform Probate Code and retains several rules that differ sharply from national trends. The most consequential is the will revocation by birth of a child. Under Mississippi Code § 91-5-3, if you had no child when you made your will and the will doesn't provide for future children, the entire will is revoked if you later have a child or your spouse is pregnant at your death. The estate is then distributed under intestacy law. Most states handle this by giving the after-born child an intestacy share while keeping the rest of the will intact. Mississippi eliminates the entire will.
Equally surprising: divorce does NOT automatically revoke provisions in favor of a former spouse. In most states, when you divorce, any gifts to your ex-spouse in the will are automatically revoked. Mississippi does not do this. If you divorce and don't make a new will, your former spouse still inherits.
Mississippi's intestacy rules are also unusual. The surviving spouse receives only a child's equal share — not a priority amount or minimum percentage. If there are three children, the estate is split four ways equally. This gives the surviving spouse less than in virtually any other state.
On the procedural side, Mississippi has genuine advantages. The creditor claim period is 90 days — the shortest in the nation — which means estates can close faster than in most states. The muniment of title procedure allows real property to transfer through a simple court order when non-real-estate assets are under $10,000, without appointing an executor or notifying creditors. And Mississippi's elective share is limited to the probate estate, which means assets in trusts and nonprobate accounts are excluded — making trusts a powerful planning tool for second-marriage situations.
Mississippi is also one of the very few states that still recognizes nuncupative (oral) wills, though their use is extremely limited: only during 'last illness,' at the testator's residence, and limited to $100 in personal property unless proved by two witnesses specifically called by the testator.
Without a Will: How Mississippi Distributes Your Estate
Mississippi follows common law property rules. When someone dies without a will, state intestacy law determines who inherits — and the result depends on your family structure.
Mississippi's intestacy rules stand alone nationally in how they treat the surviving spouse. While most states give the spouse at least a priority share — often the first $50,000 to $100,000 plus a percentage of the remainder — Mississippi does not.
If there are children, the surviving spouse receives only a child's equal share. With one child, the estate is split 50/50. With two children, it's split three ways. With four children, the spouse receives one-fifth. If there are no children, the spouse inherits everything. There is no priority, no minimum, and no first-dollar preference for the surviving spouse.
Married with children (same marriage)
Surviving spouse and children share equally — the spouse receives only a child's equal share. With two children, the spouse gets one-third; with three children, one-fourth. The spouse does NOT receive a priority or minimum share.
Married with children from a prior relationship
Same rule — equal shares among spouse and all children regardless of parentage.
Married, no children
Surviving spouse inherits the entire estate.
Single with children
Children inherit the entire estate equally. Descendants of a deceased child inherit that child's share by representation.
Single, no children
Parents inherit equally. If no parents, siblings inherit. If a sibling predeceased but left children, those children (nieces/nephews) inherit the sibling's share. If no parents or siblings, grandparents, aunts, uncles, and cousins inherit based on degree of kinship.
Survival period: Not specified by statute for general intestacy
Mississippi is unique in treating the surviving spouse as just another equal share alongside children. Most states give the spouse at least a priority share or a minimum amount. Mississippi does not. Half-blood relatives inherit only AFTER whole-blood relatives — unusual among states that typically treat them equally. Adopted children can inherit from BOTH adoptive AND natural parents — also unusual. The homestead is exempt from creditor claims when the decedent is survived by a spouse and/or descendants.
Wills in Mississippi
What makes a will valid
A written will signed by the testator and attested by at least two credible witnesses who sign in the testator's presence. The testator must 'publish' the will (declare it is their will). Alternatively: a holographic will entirely in the testator's handwriting, dated, and signed.
What people think
That a will made before having children remains valid, or that divorce automatically revokes provisions for a former spouse.
What actually happens
Mississippi has two major traps. First: if you had no children when you made your will and the will doesn't provide for future children, the entire will is revoked when a child is born. Second: divorce does NOT automatically revoke provisions for a former spouse — your ex still inherits unless you make a new will. Both of these rules are different from most other states.
Common failure
Wills made before having children that are entirely revoked by the birth, and wills not updated after divorce that still leave everything to a former spouse. Also: holographic wills where portions are typed or pre-printed.
When a trust is better
When you want to avoid probate (especially since Mississippi generally requires an attorney), when managing distributions to minors, when privacy matters, or when you want to limit the surviving spouse's elective share (which is limited to the probate estate in Mississippi).
Execution checklist
- Ensure the testator is 18+ and of sound mind
- Put the will in writing — electronic wills are not valid
- Sign the will
- Declare to two witnesses that the instrument is your will ('publication')
- Have both witnesses sign in the testator's presence
- Include provisions for future children to prevent will revocation by birth
- Execute a self-proving affidavit (notarized) — strongly recommended
- Update the will after any divorce — Mississippi does NOT auto-revoke
- For holographic wills: entire document must be in your handwriting, dated, and signed
Power of Attorney in Mississippi
What it does
Grants authority to a named agent to manage financial and legal affairs on behalf of the principal. Healthcare decisions require a separate advance health-care directive.
Key rule
Mississippi follows the Uniform Power of Attorney Act. The POA must include specific durability language to survive incapacity.
Real-world friction
Financial institutions may require their own POA forms in addition to or instead of the statutory form. Having the POA recorded with the county may help when dealing with real estate.
Common mistake
Assuming a financial POA covers healthcare decisions. Mississippi separates these authorities — you need both a durable financial POA and an advance health-care directive.
Healthcare Directive in Mississippi
What it covers
Your preferences for life-sustaining treatment and the designation of a healthcare agent to make medical decisions if you cannot communicate your wishes.
What's different
Mississippi's advance health-care directive combines the living will and healthcare agent designation in one document. The state adopted the Uniform Health-Care Decisions Act.
Execution requirements
Two witnesses required. The healthcare agent and employees of the treating facility should not serve as witnesses.
Common misunderstanding
Confusing a financial POA with a healthcare advance directive. They are separate documents with different legal authority. Without an advance directive, medical decisions fall to a statutory surrogate hierarchy.
Probate in Mississippi
When required
When assets are held solely in the decedent's name without a beneficiary designation, joint ownership, or trust — and the estate exceeds $75,000 (or $10,000 for non-real-estate assets with real property using muniment of title).
What makes Mississippi different
Mississippi probate is handled by chancery courts and generally requires an attorney. The state has the shortest creditor claim period in the nation at 90 days. The muniment of title procedure is uniquely powerful for real property estates with minimal other assets — no executor is appointed and no creditors are notified. The elective share is limited to the probate estate, which means trusts and nonprobate assets are excluded from the calculation.
Probate paths
Small estate affidavit· Weeks to a few months
For estates under $75,000. Simplified procedure to transfer assets.
Muniment of title· Weeks
For estates with real property where non-real-estate assets don't exceed $10,000. No executor appointed, no creditor notice. Court order serves as deed substitute.
Standard administration· 6–12 months
Full chancery court process. 90-day creditor claim period. Attorney generally required.
What people get wrong
Not knowing about the muniment of title option — families with a home and minimal other assets can transfer the real estate through a streamlined court order without full probate. Also: not realizing the 90-day creditor period is one of the shortest in the country, which means Mississippi estates can close faster than most.
Trusts in Mississippi
When a trust is useful
Avoiding probate and the attorney requirement, maintaining privacy, managing distributions to minors or spendthrift beneficiaries, or limiting the surviving spouse's elective share (which is limited to the probate estate in Mississippi). Trusts effectively reduce the elective share calculation.
When a trust is unnecessary
Small estates under $75,000 (which can use the simplified affidavit), or estates consisting primarily of real property with minimal other assets (which can use muniment of title).
Key mistake
Not funding the trust — an unfunded trust doesn't avoid probate. Also: not understanding that Mississippi's elective share is limited to the probate estate. Moving assets into a trust reduces what the surviving spouse can claim through the elective share — a significant planning consideration for second marriages.
Common Mistakes
Not providing for future children in a will
Mississippi revokes the ENTIRE will if you had no child when you made it and later have one (or your spouse is pregnant at death) without providing for future children. Most states just give the after-born child an intestacy share. Mississippi wipes out the whole will.
Not updating a will after divorce
Mississippi does NOT automatically revoke provisions in favor of a former spouse upon divorce — unlike most states. If you don't make a new will, your ex still inherits under the old one.
Assuming the surviving spouse gets at least half under intestacy
In Mississippi, the spouse receives only a child's equal share. With three children, the spouse gets one-fourth. Most states give the spouse at least the first $50,000–$100,000 or half the estate.
Not knowing about muniment of title
If the primary asset is real property and other assets are under $10,000, the muniment of title procedure transfers real estate without full probate — no executor, no creditor notice, just a court order that serves as a deed.
Assuming the elective share reaches into trusts
Mississippi's elective share is limited to the probate estate. Assets in a revocable trust, life insurance, and joint accounts are NOT included. This makes trusts a powerful tool for limiting the surviving spouse's claim in second-marriage situations.
Half-blood siblings expecting equal shares
Mississippi gives preference to whole-blood relatives over half-blood relatives — your half-sibling won't inherit if a whole-blood sibling is alive. This is different from most states that treat half-blood and whole-blood equally.
Missing the 90-day creditor claim deadline
Mississippi has the shortest creditor claim period in the nation. If the executor properly publishes notice, creditors who fail to file within 90 days are barred. This is an advantage for fast estate administration.
What Most People Actually Need
Most people don't need a trust. They need a valid will, a durable power of attorney, and a healthcare directive — executed correctly under Mississippi law. The most common mistakes are ones of execution, not planning.
Check your situation →Frequently Asked Questions
Does Mississippi have an estate tax or inheritance tax?›
No. Mississippi does not impose a state estate tax or inheritance tax. Only the federal estate tax applies, which currently affects estates exceeding $15 million (2026 threshold).
What happens to a will when a child is born in Mississippi?›
If you had no child when you made your will and the will doesn't provide for future children, the entire will is revoked when a child is born or your spouse is pregnant at death. Your estate is distributed under intestacy law as if no will existed. This is far more drastic than most states, which typically just give the after-born child an intestacy share.
Does divorce revoke a will in Mississippi?›
No. Unlike most states, Mississippi does NOT automatically revoke provisions in favor of a former spouse upon divorce. If you divorce and don't make a new will, your ex-spouse still inherits. This is a critical planning issue.
How does the surviving spouse share under intestacy in Mississippi?›
The spouse receives only a child's equal share. If there are two children, the estate is split three ways equally. With no children, the spouse inherits everything. Mississippi is unique in not giving the spouse a priority or minimum amount.
What is muniment of title in Mississippi?›
A streamlined procedure for estates whose primary asset is real property and non-real-estate assets don't exceed $10,000. No executor is appointed, no creditors are notified, and the court's order serves as a deed substitute to transfer real estate. Much faster and cheaper than full probate.
Does Mississippi recognize oral wills?›
Yes — Mississippi is one of the very few states that still recognizes nuncupative (oral) wills. However, they are limited to $100 in personal property unless proved by two witnesses called by the testator, and must be made during the testator's 'last illness' at their residence.
Can the elective share reach into a trust in Mississippi?›
No. Mississippi's elective share is limited to the probate estate. Assets in revocable trusts, life insurance, retirement accounts, and joint accounts are not included. This means trusts can be used to limit what the surviving spouse can claim.
How long do creditors have to file claims?›
90 days from the first publication of notice to creditors — the shortest creditor claim period in the nation. Claims not filed within this window are barred.
