You need to sit down with a probate attorney who can listen to the facts of your case and then explain how the laws of Michigan will impact your situation. It really depends on your circumstances. Feel free to call me to discuss the costs involved.
Wills may be challenged for a number of reasons, including lack of testamentary capacity, undue influence, fraud, mistake, among others. Here's a link to a short article I wrote a few years ago that explains this in more detail. http://www.probatelitigationmi.com/lawyer-attorney-1393406.html

Challenging a will is difficult, but it can be done. You can challenge a will if facts indicate that the will was not properly made or was the result of fraud, mistake, or improper influence on the person who made the will - referred to as the "decedent" after death. Each state has probate courts where any challenges to a will must be filed. Whether a challenge is in your best interests depends on the laws of the state where it will be filed.
