How to Make a Valid Will in Michigan
Michigan has specific rules about who can make a will, how it must be signed, how many witnesses are needed, and whether notarization is required. Here's everything you need to know about creating a valid last will and testament in MI.
Michigan Will Requirements at a Glance
Michigan in depth
Michigan is one of the more forgiving states about how a will is made: it recognizes handwritten wills, it does not require a notary for validity, and a court can even rescue a document that was never executed as a will at all if the intent is clear enough. A widely-cited Michigan case even admitted a will typed on a phone through that rule. But that flexibility breeds its own traps — people write an undated "holographic" will that fails, or count on the harmless-error rescue as if it were a plan.
The statute facts above give you the rules. This section covers where Michigan wills actually go wrong, and the protections built into Michigan's Estates and Protected Individuals Code (EPIC) that you cannot draft around.
Five ways a Michigan will goes wrong
Most Michigan wills that fail, fail on how they were made — not on what they say. These are the recurring ones.
- 1
A handwritten will that isn't dated
Michigan recognizes holographic (handwritten) wills, but only if the document is dated and the testator's signature and material portions are in the testator's own handwriting (MCL 700.2502(2)). The date is a hard requirement, not a nicety — leave it off and the document is not a valid holographic will. If it also has no two witnesses, it is not a valid attested will either. Write the date in your own hand, every time.
- 2
Treating the harmless-error rule as a plan
Michigan's harmless-error statute lets a court honor a document that wasn't executed correctly if the proponent proves by clear and convincing evidence that the decedent intended it as a will (MCL 700.2503). It is a genuine safety valve — it is how a Michigan court admitted a will typed on a phone. But it is an expensive courtroom fight argued after you are gone, with no guarantee. Sign a proper witnessed will; don't build your plan on a rescue.

Assuming a notary makes the will valid — or self-proving by itself
Notarization is not required to make a Michigan will valid; two witnesses are what matter (MCL 700.2502(1)). A notary's separate job is to turn a properly witnessed will into a self-proved will, so the witnesses never have to testify later (MCL 700.2504). Notarizing a will that lacks two valid witnesses does not save it. Get the two witnesses first; add the notarized self-proving affidavit second.

Witnesses who don't sign within a reasonable time
Each of your two witnesses must sign within a reasonable time after witnessing either your signing of the will or your acknowledgment of your signature (MCL 700.2502(1)). Mailing the will around to collect signatures long after the fact invites a challenge. The safe move is to get the testator and both witnesses in one room and have everyone sign together.

Signing electronically and assuming it counts
Michigan has not enacted a dedicated electronic-wills statute as of 2026. Electronic documents have been admitted only through the harmless-error rule (MCL 700.2503), after a contested court fight — not because e-signatures are formally valid. A scanned PDF or an e-signed file is not a reliably valid Michigan will. The valid route remains a physical document signed in wet ink before two witnesses.
You can't fully disinherit a spouse in Michigan
Even if your will leaves a surviving spouse nothing, Michigan gives them a right to elect against the will. A spouse who elects takes one-half of the share they would have received had you died intestate, reduced by one-half of the value of property they received from you by other means such as joint accounts or beneficiary designations (MCL 700.2202). Michigan is not a community-property state, so this elective share — not automatic ownership of half the marital estate — is the spouse's core protection.
On top of the elective share, a surviving spouse is entitled to a homestead allowance of $15,000 (MCL 700.2402) and exempt property up to $10,000 (MCL 700.2404), both adjusted for inflation, plus a reasonable family allowance during administration (MCL 700.2403). These come off the top before general devises. If your plan depends on leaving a spouse less than these amounts, build them into the plan — the court applies them regardless of what the will says.
The spouse or child you forgot: Michigan's omitted-heir rules
If you marry after signing your will and never update it, your new spouse is entitled to an intestate share — what they would have received had you died without a will — unless the will was made in contemplation of the marriage, says it survives a later marriage, or you provided for the spouse outside the will intending to substitute for a testamentary gift (MCL 700.2301).
The same idea protects a child born or adopted after the will who is left unprovided for: they generally take what they would have received had you died intestate (MCL 700.2302). Both rules fall away if the omission was clearly intentional or you provided for the person outside the will. The safe move is simple — revisit the will after any marriage, divorce, or new child.
Handwritten wills are valid — but date them and write the key terms yourself
A Michigan holographic will needs no witnesses and no notary. What it needs is a date, plus your signature and the material portions — who gets what — in your own handwriting (MCL 700.2502(2)). A printed or store-bought form with the key terms typed in is not a valid holographic will, and without two witnesses it is not a valid attested will either.
The most common way a Michigan handwritten will fails is the missing date. It is a hard statutory requirement here. A handwritten will is a genuine emergency option in Michigan, but a witnessed, typed will is far easier to prove and far harder to attack.
Interested witnesses don't void the will — and Michigan doesn't purge the gift
In many states, a gift to someone who also served as a witness is automatically cut down or voided. Michigan takes the opposite approach: an individual generally competent to be a witness may witness a will, and the signing of a will by an interested witness does not invalidate the will or any provision of it (MCL 700.2505). There is no purging statute that strips the witness-beneficiary's gift.
That is more forgiving than New York or California, but it is not a license to be careless. A beneficiary who serves as a witness still hands a will contestant an argument about undue influence. The cleanest practice is still to use two disinterested witnesses who inherit nothing.
Michigan gives you a fill-in-the-blank statutory will
Michigan is one of a handful of states that publishes a statutory will — a standardized, fill-in-the-blank form written into the code itself (MCL 700.2519). A will executed on that form and otherwise in compliance with it is a valid will, and anyone who prints and distributes the form must reproduce it verbatim, with the notice provisions in 10-point boldface type.
The statutory will lets you name beneficiaries, leave specific cash gifts, give everything else to your spouse or children, and nominate a personal representative and a guardian for minor children — but it is deliberately basic and cannot be customized beyond its blanks. It still must be signed and witnessed by two people like any other attested will. For a simple estate it is a legitimate option; for anything with trusts, blended families, or tax planning, it will not be enough.
Common questions about Michigan wills
Does a will need to be notarized in Michigan?
No. A Michigan will is valid when you sign it and at least two witnesses sign within a reasonable time after witnessing your signing or your acknowledgment of it (MCL 700.2502(1)). Notarization is not required for validity. A notary's separate role is to make the will "self-proved" through a self-proving affidavit (MCL 700.2504), so your witnesses never have to testify in probate. Notarizing adds convenience later but never replaces the two witnesses.
Are handwritten wills legal in Michigan?
Yes. Michigan recognizes holographic (handwritten) wills with no witnesses and no notary, but only if the document is dated and your signature and its material provisions are in your own handwriting (MCL 700.2502(2)). The date is a strict requirement — an undated handwritten will is not a valid holographic will. If you use a printed form with the key terms typed, it is not a valid holographic will and, without two witnesses, not a valid attested will either.
How many witnesses does a will need in Michigan?
Two. A standard Michigan will must be in writing, signed by you (or by someone else at your direction in your conscious presence), and signed by at least two witnesses, each of whom signs within a reasonable time after witnessing you sign the will or acknowledge your signature (MCL 700.2502(1)). The one exception is a holographic will, which needs no witnesses if it is dated and handwritten (MCL 700.2502(2)).
Can my spouse be left out of a Michigan will?
Not entirely. A surviving spouse can elect against the will and take one-half of the share they would have received had you died intestate, reduced by one-half of property they received from you by other means (MCL 700.2202). Michigan is not a community-property state, so this elective share is the spouse's main protection, along with a $15,000 homestead allowance (MCL 700.2402) and exempt property up to $10,000 (MCL 700.2404). A spouse you marry after signing the will can also claim an intestate share (MCL 700.2301).
Does Michigan have a statutory will form?
Yes. Michigan publishes a fill-in-the-blank statutory will directly in the code (MCL 700.2519). A will executed on that form and otherwise in compliance with it is valid, and printers must reproduce it verbatim with the notice in 10-point boldface type. It lets you make cash gifts, leave the residue to your spouse or children, and name a personal representative and guardian — but it is deliberately basic, cannot be customized beyond its blanks, and still must be signed before two witnesses.
