Michigan Will Witness Requirements: Who Can Sign, Who Should Not

The two witnesses you pick to watch you sign your will matter more than most Michigan DIYers realize. Under MCL 700.2502, a witnessed will is one of the two ways to create a valid Michigan will (holographic is the other, rare option). Get the witnessing wrong and your will can be admitted to probate but successfully contested; get it right and even a highly-motivated challenger will lose. This guide explains exactly who can serve as a Michigan will witness, who technically can but never should, the five mistakes that get DIY wills challenged, and the safe signing ceremony playbook that Michigan attorneys use.

The 30-Second Answer

Michigan requires two witnesses to sign a typed or printed will under MCL 700.2502(1). Each witness must (a) be generally competent, meaning they can truthfully recall what they saw, (b) sign within a reasonable time after seeing the testator sign or hearing the testator acknowledge the signature, and (c) preferably be at least 18 and not receive anything under the will. Michigan does NOT invalidate a will signed by an "interested" (beneficiary) witness under MCL 700.2505 -- but you should never use a beneficiary as a witness anyway. A notary is not required but strongly recommended (a self-proving affidavit under MCL 700.2504 creates a conclusive presumption of proper execution).

What MCL 700.2502 Actually Requires

Michigan's will execution statute is short and specific. Per MCL 700.2502(1), a valid attested Michigan will must be:

1. In writing. Typed, printed, or handwritten -- but never oral. Voice recordings and video wills are not valid in Michigan.
2. Signed by the testator (or by another individual in the testator's conscious presence and at the testator's direction, if the testator is physically unable). This is why "the person the testator directs to sign" cannot also be a witness -- they've already served their signing role.
3. Signed by at least two individuals, each of whom signed within a reasonable time after they (a) witnessed the testator sign, or (b) heard the testator acknowledge their signature, or (c) heard the testator acknowledge the will.

Two things Michigan does NOT require, contrary to popular belief:

• The witnesses do NOT need to be in the same room at the same time as each other. Michigan's dual-presence rule was eliminated when EPIC took effect on April 1, 2000. Under current law, the witnesses need only sign in a "reasonable time" after witnessing (or hearing the acknowledgment of) the testator's signature. Best practice is still to have everyone sign at once, but it is not a statutory requirement.
• The will does not need to be dated. Michigan has no dating requirement for attested wills under MCL 700.2502(1). (Holographic wills DO have a dating requirement -- see below.) Best practice is to date every will anyway.

The testator must also be 18 or older with "sufficient mental capacity" under MCL 700.2501. This means the testator understands (a) that they are directing disposition of their property after death, (b) the nature and extent of their property, (c) the natural objects of their bounty (the family members who would ordinarily inherit), and (d) the general effect of signing the will.

The Interested-Witness Rule (and Why You Should Still Avoid It)

Michigan is one of the states that has abolished the "interested witness" rule. Under MCL 700.2505, a will is not invalidated because one of the witnesses is also a beneficiary. Nor does the beneficiary-witness forfeit their gift under the will (as they would in some other states).

Per the Michigan Bar analysis of MCL 700.2505: "The purpose of this change was not to foster use of interested witnesses, as attorneys routinely prefer using disinterested witnesses in execution of wills. Rather, this change recognized that interested witness penalties did more harm than good."

Practically translated: you technically can use your daughter as a witness to a will that names her as a beneficiary. You should never actually do this.

Why not? Because "not invalidating the will" is a very different thing from "not being challenged." Per the analysis at BBA Law's Michigan wills page: "A beneficiary who watched you sign is Exhibit A in an undue influence challenge. When the person who inherits is the same person who witnessed the signing, every disappointed heir's attorney sees an opening."

The whole point of witnesses is that they can testify years later, if needed, that you were of sound mind and not being manipulated when you signed. If your witnesses are the exact people who benefit from your decisions, that testimony has no independent value. Use disinterested witnesses. Every time.

Who Qualifies as a Michigan Witness

Michigan requires witnesses to be "generally competent" -- per Michigan Rules of Evidence, this means they must be able to truthfully recall the circumstances under which the will was signed. No formal age is stated in the will-execution statute, but every Michigan attorney recommends witnesses be at least 18.

Beyond that, the pool of acceptable witnesses is broad. Michigan does NOT require witnesses to be:

• Residents of Michigan (out-of-state witnesses are fine)
• U.S. citizens
• Family members or unrelated -- either works, though disinterested is strongly preferred
• Attorneys, notaries, or professionally credentialed
• Physically present in the same room as each other

The ideal Michigan witness is: (a) at least 25 years old and reasonably likely to outlive you, (b) not a beneficiary or the spouse of a beneficiary, (c) not the personal representative you named in the will, (d) able to be located in the future if needed, and (e) willing to sign a self-proving affidavit before a notary.

Common good choices: coworkers, neighbors, friends who are not in the will, bank tellers (many Michigan banks will supply two employees as witnesses if you bring the will in with the notary), lawyers or paralegals in an office, or adult non-family friends.

Common bad choices: your spouse, your children, your siblings if they are in the will, anyone under 18, close family friends who might be named in future revisions, an employee whose employment depends on you, or anyone with early-stage cognitive impairment.

Five Mistakes That Invalidate Michigan Wills

Mistake 1: One Witness, Not Two

The number-one DIY failure. Some Michigan testators sign in front of only one witness, or think a notary counts as a witness. A notary does NOT count. Two separate individuals must witness the signing OR acknowledge the signature. If only one witness signs, the will fails MCL 700.2502(1) and is invalid (though Michigan's harmless-error statute, MCL 700.2503, gives courts limited authority to save such wills on clear and convincing evidence of intent).

Mistake 2: Witnesses Sign Days or Weeks Later

MCL 700.2502(1)(c) requires witnesses to sign "within a reasonable time" after witnessing the signing or the acknowledgment. Michigan case law suggests "reasonable" means days, not months. Best practice: all three signatures happen the same day. If a witness cannot sign that day, do a fresh signing ceremony with different witnesses.

Mistake 3: Beneficiary as Witness

Legally survivable but practically fatal. See the interested-witness section above. Any Michigan probate contest brought by a disappointed heir will start with "the beneficiary who witnessed the will influenced the testator" -- and even if you win, you spend thousands of dollars proving something obvious.

Mistake 4: Witnesses Not in Testator's Presence

Michigan eliminated the dual-witness-presence rule but preserved the testator-presence rule: witnesses must sign within a reasonable time after they either watched you sign or heard you acknowledge the signature. If you sign your will alone at your kitchen table, then hand it to two people separately over the next week saying "sign this," the witnesses have not properly attested. The testator's acknowledgment must be to each witness.

Mistake 5: Witness Signs in the Wrong Place

The will must be signed by the witnesses -- ideally in the attestation block at the end. Witnesses initialing pages of the will is not a substitute for a signature. Every proper Michigan will includes a clearly-marked "Witness" signature line with a printed name and address block. If your template does not have this, use one.

The Safe Signing Ceremony Playbook

1. Recruit two disinterested witnesses in advance. Not the day of. Give them a heads-up so they clear time.
2. Schedule a notary appointment if you want the self-proving affidavit (strongly recommended). Bank branches (free if you have an account), UPS Stores, AAA offices, and Michigan Secretary of State offices all offer notaries. Bring both witnesses.
3. Assemble the will and the self-proving affidavit in a folder. Do not staple or bind -- the notary needs to see original signatures.
4. Read the attestation clause aloud (something like "This is my will, and I am asking you to witness my signature"). This creates a clean acknowledgment for MCL 700.2502(1)(c) purposes.
5. Sign the will in front of both witnesses. Sign the same way you sign everything else -- consistency matters if challenged.
6. Each witness signs the will in the attestation block, prints their name, and adds their address. This ensures locatability years later.
7. Move to the self-proving affidavit. All three of you sign it in front of the notary, who then notarizes.
8. Store the original will safely. A fireproof home safe, a safe deposit box, or with the probate court under MCL 600.880c ($25 filing fee).
9. Notify your personal representative that the will exists and where it is located.

The Self-Proving Affidavit (MCL 700.2504)

Michigan's self-proving affidavit is technically optional but universally recommended. It is a separate sworn statement, signed by you and the two witnesses before a notary, that certifies the will was executed with proper formalities. Under MCL 700.2504, a properly self-proved will creates a "conclusive presumption" of proper signature at probate -- meaning the witnesses never have to testify.

Why does this matter? Because 20 years from now, when your will is offered for probate, your two witnesses may be dead, retired, out of state, or hard to locate. Without the self-proving affidavit, someone has to track them down and put them on the stand. With it, probate proceeds without witness testimony.

The self-proving affidavit is short -- one page. It states substantially: "The testator declared this document to be their will, signed it in our presence, and we signed it in a reasonable time after witnessing." The notary acknowledges all three signatures. Total added time at the signing ceremony: about 5 minutes.

The No-Witness Exception: Holographic Wills

MCL 700.2502(2) allows a Michigan will to be valid without witnesses if it is (a) dated, (b) signed by the testator, and (c) the material portions are in the testator's own handwriting. This is called a "holographic will" -- a fully handwritten will.

Holographic wills are useful for emergencies (deathbed situations, last-minute changes) but are risky as a primary tool. Per Leydorf Law's analysis, "if the material portions are not in the person's handwriting, additional evidence is required to show that those parts were meant to be included." Michigan courts have thrown out holographic wills that were partially typed, mixed with printed forms, or lacked clear testamentary intent.

If you are healthy and not in an emergency, use a witnessed attested will. If you are in a genuine emergency, a signed handwritten dated statement can serve until you get to a proper signing ceremony. See our Michigan will revocation guide for the mechanics of superseding a holographic emergency will with a proper witnessed will.

Frequently Asked Questions

Can my spouse be a witness to my Michigan will?

Technically yes if they are not a beneficiary. But most Michigan wills leave the residuary estate to the surviving spouse, making the spouse an interested witness. In that case, having the spouse witness the will opens you to challenges. Use a disinterested witness instead.

Can my adult child witness my will if I named them as personal representative but did not give them any money?

Being named as personal representative alone does not make them an "interested witness" under Michigan law -- the interested-witness rule concerns beneficiaries. That said, using your own child as a witness invites the same challenges as an interested witness. Pick someone else.

Do witnesses need to read my will?

No. Michigan witnesses attest to the fact that you signed, not to the contents of the will. They should NOT read the will unless you explicitly want them to. In fact, keeping witnesses ignorant of the will's contents protects your privacy.

Can witnesses be under 18 in Michigan?

The statute does not set a minimum witness age, but Michigan attorneys uniformly recommend witnesses be 18 or older. A minor's testimony is weaker if the will is later challenged. See Michigan Legal Help's Making a Will in Michigan guide: "Witnesses must be 18 or older."

Can I use my neighbors as witnesses if they barely know me?

Yes. Michigan does not require witnesses to know the testator well. Any adult "generally competent to be a witness" qualifies. Neighbors, coworkers, and casual acquaintances are common Michigan witness choices.

What if I can only find one willing witness?

Do not sign the will. Michigan requires two. Ask a bank branch to supply the second witness at your notary appointment -- most banks and UPS Stores routinely do this if you bring the will in for notarization.

Can the notary who acknowledges my self-proving affidavit also count as a witness?

Yes, if the notary also signed the will as a witness. The two roles are separate but can be performed by the same person. However, the safer path is to have two lay witnesses PLUS the notary.

Does Michigan recognize a will signed by a witness who has since died?

Yes. The death of a witness does not invalidate the will. If the will has a self-proving affidavit, no witness testimony is needed at probate. If it does not, alternative proofs (handwriting authentication, other testimony) may be used.

Can I sign my Michigan will over Zoom with remote witnesses?

Michigan enacted temporary remote signing rules during the COVID-19 pandemic under Executive Order 2020-41. Those rules expired. As of 2026, Michigan does NOT allow remote-witnessed wills. All witnesses must be physically present with the testator (or with the acknowledged signed will).

What happens if my will has three witnesses instead of two?

Nothing bad -- extra witnesses are welcome. Michigan requires "at least" two under MCL 700.2502(1)(c). Some Michigan attorneys routinely use three witnesses when they can, on the theory that redundancy helps if one witness later becomes unavailable.
