Who Can Legally Witness a Last Will and Testament in Mississippi?

Asking a spouse, adult child, or close friend named in your will to sign as a witness at the kitchen table is one of the most destructive mistakes in Mississippi estate planning. While the document itself might still be admitted to probate in Chancery Court, Mississippi enforces a strict purging statute (Miss. Code Ann. § 91-5-9) that automatically strips an attesting witness of their inheritance if the will cannot be proven without their signature.

Even when witnesses have no financial stake in the estate, simple procedural errors-such as failing to tell the witnesses that the document is a will or omitting witness street addresses on the affidavit-can jeopardize probate and trigger costly litigation. This guide explains who can legally witness a Last Will and Testament in Mississippi, the difference between interested and disinterested witnesses, the financial penalties of the purging statute, and the exact role of a notary public.

Legal Requirements for Will Witnesses in Mississippi

Under Miss. Code Ann. § 91-5-1, any non-holographic (typed or printed) Last Will and Testament or codicil in Mississippi must be attested by two or more credible witnesses in the physical presence of the testator. In Mississippi probate law, the term credible means a person who is legally competent to testify in a court of law at the time of the signing.

• Age and Mental Capacity: Witnesses should be legal adults (at least 18 years of age) and of sound mind so they can reliably testify in Chancery Court about the testator's mental capacity and voluntary signature if a will contest arises.
• Conscious Physical Presence: Both witnesses must sign the will in the direct, conscious presence of the testator. As noted in Estate of Willis v. Willis, 207 So. 2d 348 (MS Supreme Court 1968), strict compliance with two-witness attestation is mandatory to establish due execution.
• Mandatory Publication of the Will: Under Griffith v. Griffith (In re Estate of Griffith), 30 So. 3d 1190 (MS Supreme Court 2010), Mississippi law requires that attesting witnesses know they are witnessing a Last Will and Testament. If a testator covers up the text or leads witnesses to believe they are signing a routine medical form or power of attorney, the will is legally invalid.
• Creditors as Competent Witnesses: Under Miss. Code Ann. § 91-5-13, if a will charges land or personal property with the payment of debts, a creditor whose debt is secured by that provision is still legally competent to serve as a subscribing witness.

Interested vs. Disinterested Witnesses Under Mississippi Law

To protect your estate plan from challenges in Chancery Court, estate planning attorneys always use disinterested witnesses-individuals who have no blood or marital relationship to you and receive zero financial benefit under the will.

What Happens If a Beneficiary Signs as a Witness? (The Purging Statute)

An interested witness is someone who is given a devise (real estate) or bequest (money or personal property) in the will they are witnessing. Under Mississippi's purging statute, Miss. Code Ann. § 91-5-9, having a beneficiary sign as one of your witnesses does not void the entire will. Instead, as the Mississippi Supreme Court held in Estate of Crawford v. Crawford, 225 Miss. 208 (MS Supreme Court 1955) and Swanzy v. Kolb, 94 Miss. 10 (MS Supreme Court 1908), the witness remains legally competent (and can be compelled by the court to testify to validate the rest of the will), but the devise or bequest made to that witness is declared void.

There are only two narrow exceptions under Miss. Code Ann. § 91-5-9 that can save all or part of an interested witness's inheritance:

1. Supernumerary (Extra) Disinterested Witnesses: The statute voids the gift only if 'the will cannot otherwise be proven.' If three people witnessed the will-two disinterested witnesses plus one beneficiary-the will can be proven by the two disinterested witnesses alone, preserving the beneficiary's gift.
2. The Intestate Share Cap: If the interested witness is a blood heir or spouse who would have inherited a share of the estate under Mississippi intestacy laws (Miss. Code Ann. § 91-1-7) had no will been written, the witness is allowed to keep so much of their intestate share as does not exceed the value of the gift in the will.

Can Family Members, Spouses, or Executors Witness a Will?

Whether a relative or fiduciary can serve as a witness depends on their exact role in the document and the risk of an undue influence lawsuit:

Financial Consequences When a Beneficiary Signs as a Witness

To see how devastating Miss. Code Ann. § 91-5-9 can be in real dollar terms, consider two common Mississippi probate scenarios:

• Scenario A (Unmarried Partner or Lifelong Friend): You own a $250,000 estate in Gulfport and sign a will leaving $100,000 to your unmarried partner, asking them and a neighbor to sign as your two witnesses. Because an unmarried partner has a $0 intestate share under Miss. Code Ann. § 91-1-7, their entire $100,000 bequest is voided under Miss. Code Ann. § 91-5-9. They are forced to validate the will while walking away with nothing.
• Scenario B (Child Receiving a Larger Share): A widowed mother in Jackson has four children and an estate worth $400,000. Because her youngest daughter cared for her for years, she leaves $250,000 to the youngest daughter and $50,000 each to the other three children, but the youngest daughter signs as one of the two witnesses. Under Miss. Code Ann. § 91-5-9, the daughter's $250,000 gift is purged down to her one-fourth intestate share ($100,000), costing her $150,000 directly due to the witnessing error.

The Exact Role of a Notary Public and Self-Proving Affidavits

In Mississippi, a notary public and a subscribing witness perform two completely different legal functions, and confusing them can derail probate.

Role and Disqualifications of a Mississippi Notary Public

Notarization is not required to make a will legally valid under Miss. Code Ann. § 91-5-1; rather, the notary public administers the oath and certifies the signatures on the Self-Proving Affidavit. Under the Revised Mississippi Law on Notarial Acts (Miss. Code Ann. § 25-34-7), regulated by the Mississippi Secretary of State, Business Services Division, Jackson (where notaries are commissioned via Form NP-001, Mississippi, Secretary of State, Application for Notary Public Commission), a notary is strictly prohibited from notarizing a document if the notary is a party to the record, receives a direct beneficial interest, or is a spouse, child, sibling, parent, grandparent, grandchild, aunt, uncle, niece, nephew, stepchild, or in-law of the person signing. Any notarial act performed in violation of Miss. Code Ann. § 25-34-7 is voidable. By statute (Miss. Code Ann. § 25-34-9), a Mississippi notary may charge up to $5.00 per notarial act.

How to Use a Self-Proving Affidavit Properly Under Section 91-7-7

Under Miss. Code Ann. § 91-7-7, a will must be proven in Chancery Court by at least one subscribing witness unless a valid Self-Proving Affidavit is attached to or integrated into the will at execution. To ensure a Self-Proving Affidavit is effective in Mississippi Chancery Court, you must follow two strict statutory and evidentiary rules:

1. Include Every Witness's Residential Address: Miss. Code Ann. § 91-7-7 explicitly requires that the affidavit 'shall state the address of each subscribing witness.' Omitting witness addresses deprives the affidavit of its self-proving status; while the will remains valid under Miss. Code Ann. § 91-5-1, the estate is burdened with locating witnesses for live testimony or submitting handwriting proof under Miss. Code Ann. § 91-7-9.
2. Avoid the Deceased-Witness Trap: If you fail to execute a compliant Self-Proving Affidavit and both witnesses pass away or cannot be located when the will is offered for probate, Christmas v. Christmas (In re Will of Beard), 334 So. 3d 1154 (MS Supreme Court 2022) requires the estate to prove the handwriting of the testator and both subscribing witnesses-a hurdle that frequently causes older wills to be rejected.

Step-by-Step Procedure for Properly Witnessing a Will in Mississippi

Whether your will will eventually be probated in the Hinds County Chancery Court, Jackson, the Harrison County Chancery Court, Gulfport, the DeSoto County Chancery Court, Hernando, or the Forrest County Chancery Court, Hattiesburg, follow this six-step protocol:

Step 1: Screen Two or Three Disinterested Adult Witnesses

Choose at least two (and ideally three, as an extra cushion) competent adults aged 18 or older who are not named in the will and are not related to you or your beneficiaries.

Step 2: Assemble Testator, Witnesses, and Notary in One Room

Bring the testator, the witnesses, and an impartial Mississippi notary public together in the same physical room with valid government-issued photo identification. Do not let anyone leave the room until all signatures are completed.

Step 3: Formally Publish the Will to the Witnesses

Before signing, the testator must clearly state to the witnesses that the document is their Last Will and Testament and ask them to serve as attesting witnesses, satisfying Griffith v. Griffith (In re Estate of Griffith), 30 So. 3d 1190 (MS Supreme Court 2010).

Step 4: Sign the Will and Attestation Clause in Physical Presence

The testator signs the bottom of the will (and initials each prior page) while both witnesses watch. Immediately afterward, both witnesses sign the attestation clause in the presence of the testator and each other under Miss. Code Ann. § 91-5-1.

Step 5: Execute the Self-Proving Affidavit with Full Witness Addresses

The notary public places the testator and both witnesses under oath. The witnesses sign the Self-Proving Affidavit and print their full residential street addresses (Miss. Code Ann. § 91-7-7), and the notary affixes their official ink stamp and signature.

Step 6: Store the Original Will for Future Chancery Court Filing

Place the original stapled document in a secure location. Do not remove the staples to make copies, as unstapling a will raises tampering presumptions when your probate lawyer files the original with the Chancery Clerk alongside Form AOC/01, Mississippi, Administrative Office of Courts, Civil Case Filing Form Cover Sheet.

Cost and Timeline of Proper Execution vs. Witness Litigation

Conducting a proper will signing ceremony takes 20 to 30 minutes. When included in a Mississippi attorney's flat-rate will package ($300 to $600), the law firm provides disinterested staff witnesses and an in-house notary at no extra charge. Conversely, if a will is executed with interested witnesses or a defective affidavit, proving the will or litigating a Miss. Code Ann. § 91-5-9 purging dispute in Chancery Court can delay estate distribution by 6 to 18 months and cost the estate $3,500 to $15,000+ in legal fees and handwriting expert testimony.
