How can you contest a will in Michigan?

Understanding the Grounds for Contesting a Will in Michigan

Contesting a will is a legal process where an individual challenges the validity of a deceased person's last will and testament. In Michigan, like in other states, there are specific grounds upon which a will may be contested, and understanding these is crucial for anyone considering such action.

Common grounds for contesting a will include undue influence, lack of testamentary capacity, fraud, improper execution, and the existence of a more recent will. Undue influence occurs when the testator is manipulated by someone with power or influence over them, resulting in a will that does not reflect their true intentions. Lack of testamentary capacity involves the testator not having the mental ability to understand the implications of their will when it was executed. Fraud arises when the will is forged or the testator is deceived into signing it. Improper execution refers to the failure to comply with Michigan's legal formalities for signing a will. Lastly, if there is evidence of a later valid will, it supersedes any previous versions.

It is important to note that only 'interested persons' as defined under Michigan law—typically beneficiaries or would-be beneficiaries—have standing to contest a will. The process begins with filing a petition in the probate court where the estate is being administered. This must occur within a specific timeframe after receiving notice of the probate proceedings.

A historical example that illuminates the importance of proper execution comes from the case In re Estate of Attia, where the Michigan Court of Appeals ruled on disputed holographic (handwritten) wills. The courts scrutinized whether the documents met statutory requirements and illustrated how contesting parties might argue over seemingly clear expressions of intent when formalities are in question.

The process can be complex and emotionally taxing, often requiring legal assistance from an attorney experienced in probate litigation.


Contesting a will in Michigan requires thorough knowledge of legal procedures and grounds for contestation. The process can be lengthy and challenging, but understanding one's rights and how to enforce them through the courts is essential for any interested party who believes that the deceased's true intentions are not reflected in their will. As always, seeking professional legal advice early on can provide critical guidance through this difficult process.
