Your will represents your final wishes for how your property gets distributed after death. But here’s what many people don’t realize: not every document labeled as a will actually holds up in probate court. Michigan law sets specific requirements that must be met. Fail any of them, and the entire document can be tossed out. Understanding what makes a will unenforceable helps you avoid costly mistakes that could leave your estate in chaos and your family fighting in court.
Basic Legal Requirements Under Michigan Law
Michigan doesn’t mess around with will formalities. The state follows strict rules. According to Michigan Compiled Laws Section 700.2502, a valid will must meet these conditions:
- The testator (person making the will) must be at least 18 years old
- The testator must be of sound mind when signing
- The will must be in writing
- The testator must sign the document or direct someone else to sign in their presence
- At least two people must witness the signing
Miss even one element? The entire will can fail. Handwritten wills without witnesses face additional scrutiny. These are called holographic wills, and they often don’t survive probate challenges.
Mental Capacity Questions
A sound mind doesn’t mean what you might think. It means the testator understands what property they own, who their natural heirs are, and what happens when they sign the will. That’s it. The bar is actually pretty low. Someone can have dementia or other cognitive issues and still possess sufficient capacity. But if they lacked mental capacity at the exact moment of signing, the will fails. Period. Medical records become critical evidence in these disputes. So does witness testimony. The complexity of the estate plan matters too. Challenges often pop up when a will gets signed shortly after an Alzheimer’s diagnosis, during a hospital stay, or while someone’s under heavy medication.
Undue Influence and Coercion
A will signed under pressure or manipulation won’t stand. Undue influence happens when someone in a position of power over the testator uses that relationship to change the will’s terms for their own benefit. You see this with caregivers who isolate elderly individuals. Family members who threaten abandonment. Advisors who exploit trust. Courts look for warning signs like sudden changes to long-standing estate plans, unusual secrecy during the signing, or the beneficiary being heavily involved in preparing the will. The person contesting the will typically has to prove undue influence. That can be tough without clear evidence.
Fraud and Forgery Problems
Fraud invalidates a will when someone tricks the testator about what they’re signing or lies about material facts that affect the will’s contents. Think you’re signing a power of attorney, but it’s actually a will? That’s fraud. Forgery is more straightforward. If the signature isn’t genuine, the will fails completely. Handwriting experts and witness testimony usually determine these cases.
Improper Execution and Witness Issues
The witnessing process matters more than most people realize. Both witnesses must see the testator sign or acknowledge their signature. Then the witnesses sign in the testator’s presence.
A Troy will lawyer sees these problems all the time. Witnesses who stand to inherit under the will create conflicts. Michigan allows interested witnesses, but their bequests may be void if they were necessary to meet the two-witness requirement. Signatures added later cause problems. So do witnesses who didn’t actually see the signing. Incomplete witness information can sink a will too.
Revocation of Previous Wills
Sometimes a will is perfectly valid when signed, but later becomes invalid through proper revocation. You can revoke a will in several ways. Create a new one that explicitly revokes prior versions. Physically destroy the document with the intent to revoke it. Or go through certain life changes that trigger automatic revocation. Marriage after executing a will doesn’t automatically revoke it in Michigan. Divorce does, though. It revokes provisions favoring the former spouse.
How Invalid Wills Affect Your Estate
When a will gets thrown out, your estate passes under Michigan’s intestacy laws. The state decides who inherits based on a statutory formula. Not your wishes. Spouses and children receive priority, but the distribution may look nothing like what you intended. Previous valid wills may be reinstated if they weren’t properly revoked. If no prior valid will exists? The estate goes through intestate succession, and the courts take over.
