A Mississippi last will and testament must meet three requirements to hold up in court: the person making it has to be at least 18, has to be of sound mind, and has to sign a written document at the end in the presence of two credible witnesses who then sign it themselves.1Justia Law. Mississippi Code 91-5-1 – Who May Execute Get any of those three wrong and a chancery court can throw the document out, sending your estate through Mississippi’s default intestacy rules instead of your wishes. The rest is detail, but the details matter: who your witnesses are, whether you add a self-proving affidavit, and how your will interacts with beneficiary designations and spousal protections all shape whether the document does what you think it does.
The Three Core Requirements
Mississippi Code 91-5-1 sets the bar. You must be at least 18 years old. You must be of sound mind at the moment you sign, which means you understand what property you own, who your natural heirs are, and what signing a will actually does. And the will must be in writing and signed at the end of the document, either by you or by someone else at your direction and in your presence.1Justia Law. Mississippi Code 91-5-1 – Who May Execute
Sound mind is judged at the moment of signing, not before or after. Someone with early dementia can still make a valid will during a lucid interval; someone who was sharp last year but confused on the day they signed may not have made a valid one. If capacity is ever going to be questioned, documentation from around the signing date is what a court will look at.
Mississippi does not recognize oral wills except in very limited circumstances. If it isn’t written down and signed at the end, it isn’t a will.
Witnesses and the Interested-Witness Problem
Your two witnesses need to be competent adults who watch you sign and then sign the document themselves in your presence. Their role is to confirm you signed voluntarily and appeared to understand what you were doing.
Here’s where people trip up: a witness who also inherits under the will is called an “interested witness,” and it creates a problem. Mississippi won’t automatically void the whole will, but the bequest to that witness can be struck unless at least two disinterested witnesses also signed.1Justia Law. Mississippi Code 91-5-1 – Who May Execute The cleanest fix is to pick witnesses who are not named anywhere in the will. Neighbors, coworkers, and friends who aren’t inheriting anything are ideal.
Adding a Self-Proving Affidavit
A self-proving affidavit is optional, but skipping it is usually a mistake. It’s a sworn statement, signed by you and your witnesses in front of a notary, confirming the will was properly executed. Without one, your witnesses may have to appear in chancery court during probate to verify their signatures. If a witness has died, moved, or simply can’t be tracked down years later, that becomes a real problem.
With a self-proving affidavit attached, the court can accept the will on the affidavit alone.2Justia Law. Mississippi Code 91-7-7 – Proof of Due Execution of Will Mississippi caps notary fees at $5.00 per signature, so the cost is negligible compared with what your executor could spend chasing down witnesses later.
Handwritten Wills in Mississippi
Mississippi recognizes holographic wills. If the document is written entirely in your own handwriting and signed by you, it’s valid without the two-witness requirement.1Justia Law. Mississippi Code 91-5-1 – Who May Execute The entire text has to be in your hand, though. A partly typed, partly handwritten document doesn’t qualify as holographic and would need the standard witness formalities to be valid.
Holographic wills work in a pinch, but they invite disputes. Handwriting must be proved at probate, the terms are often ambiguous, and there’s no self-proving affidavit protecting the document. A typed will with two disinterested witnesses and a notarized affidavit is the safer path when you have time to plan.
Changing or Revoking Your Will
You can modify a Mississippi will any time you’re alive and competent. Small changes go into a codicil, which is an amendment that has to be signed and witnessed the same way as the original. Bigger changes are usually cleaner in a new will that explicitly revokes all prior wills and codicils.
You can also revoke a will by physically destroying it — tearing, burning, or otherwise obliterating it with the intent to cancel it.1Justia Law. Mississippi Code 91-5-1 – Who May Execute Accidental destruction doesn’t count. If your will can’t be found after your death and you were the last person known to have it, Mississippi courts presume you destroyed it on purpose. Probating a copy of a lost will requires clear and convincing evidence that the original existed, was lost or destroyed without any intent to revoke, and had the contents claimed.
Life Events That Affect a Will You Already Signed
Divorce does not revoke your entire will in Mississippi, but it neutralizes any provisions benefiting your former spouse. The law treats an ex-spouse as though they died before you, so bequests and appointments naming them become void unless the will explicitly says otherwise.3Justia Law. Mississippi Code 91-5-3 Marriage doesn’t revoke a prior will either, though a new spouse left out of one has separate rights described below. If you have a child after signing your will and don’t mention that child anywhere, the child may be entitled to a share under Mississippi’s rules for pretermitted heirs.
The practical rule: review the will after any marriage, divorce, birth, death in the family, or significant change in assets.
What Your Will Cannot Override
A valid will isn’t the last word on everything you own. Two categories of rules override its terms.
Your Spouse’s Right to Renounce
Mississippi limits how completely you can disinherit a husband or wife. If your will makes no provision for your surviving spouse, or the provision is unsatisfactory to them, they can renounce the will and take the share they would have received under intestacy law instead.4Justia Law. Mississippi Code 91-5-27 – Effect of No Provision for Husband or Wife If the will leaves the spouse nothing at all, no renunciation is even required; the law treats the will as renounced automatically. The elective share is capped at one-half of the probate estate, but that cap doesn’t help you plan around it — a spouse who wants their share will get it.
Homestead protections work the same way. The family home generally can’t be reached by the deceased’s creditors while a surviving spouse or minor children occupy it, regardless of what the will says.
Assets That Skip the Will Entirely
Several types of property pass by contract or registration, not by will:
- Life insurance proceeds go to the beneficiary named on the policy.5Justia Law. Mississippi Code 83-7-7 – Policy Beneficiary Designations of Trustees
- Retirement accounts like 401(k)s and IRAs go to the beneficiary on file with the plan administrator.
- Payable-on-death bank accounts transfer directly to the named beneficiary.
- Transfer-on-death securities registrations count as contractual transfers, not testamentary ones.6Justia Law. Mississippi Code 91-21-19 – Nontestamentary Transfer on Death
- Transfer-on-death deeds for real estate, allowed in Mississippi since 2020, transfer real property to a named beneficiary at death, provided the deed is recorded with the county chancery clerk before you die.7Justia Law. Mississippi Code 91-27-17 – Requirements
- Jointly held property with right of survivorship passes automatically to the surviving owner.
Beneficiary designations win over inconsistent will language. If your will leaves your house to your sister but you’ve recorded a transfer-on-death deed naming your brother, your brother gets the house. This is the most common way estate plans quietly fall apart: people update the will and forget the beneficiary forms. Every time you touch the will, review the designations too.
After You Sign: What the Will Sets in Motion
Naming an executor in the will lets you choose who handles the estate, but the appointment isn’t automatic. The person you name has to be formally appointed by the chancery court, take an oath, and typically post a surety bond equal to the full value of the estate.8Justia Law. Mississippi Code 91-7-41 – Oath and Bond of Executor or Administrator With Will Annexed Wills commonly include a clause waiving the bond, which spares the executor the premium.
Probate itself begins when someone — usually the named executor — files the original will and a death certificate in the chancery court of the county where you lived.9Justia Law. Mississippi Code 91-7-3 – By Whom Presented10Justia Law. Mississippi Code 91-7-93 – Inventory of Money and Property Owned by Decedent at Time of Death11Justia Law. Mississippi Code 91-7-145 – Notice to Creditors of Estate Straightforward Mississippi probates run roughly six months to a year.
Two boundaries worth knowing before you finish drafting. Mississippi doesn’t impose a state estate tax or inheritance tax; for deaths after 2004, no Mississippi estate tax return is due.12Mississippi Department of Revenue. Estate And anyone who wants to challenge your will has two years from the date it’s admitted to probate to file that contest, after which the probate is final.13Justia Law. Mississippi Code 91-7-23 – Validity Contested Within Two Years A properly executed will with a self-proving affidavit and disinterested witnesses is what makes a contest hard to win.
