Contesting a Trust in Michigan: What You Need to Know Before You Act

If you believe a trust was created or changed under circumstances that weren't right — pressure from a caregiver, a parent who wasn't thinking clearly, or paperwork that appeared out of nowhere near the end of someone's life — you may have grounds to contest it. Michigan law gives certain people the right to challenge a trust, but the process has strict requirements and real deadlines. One consultation can tell you whether you have a case worth pursuing.

What Does It Mean to Contest a Trust in Michigan?

Contesting a trust means formally challenging its legal validity — arguing that the trust document itself, or a specific amendment to it, should not be enforced because it was created or modified under circumstances the law does not recognize as valid. A successful trust contest can result in an earlier version of the trust being reinstated, assets being redistributed according to a prior document, or the trust being invalidated entirely.

This is distinct from a dispute about how a trustee is managing a trust. If your concern is mismanagement or a trustee hiding assets, that is a separate legal claim — but one we handle as well.

Grounds for Contesting a Trust in Michigan

Michigan courts will consider a trust contest on several recognized legal grounds. Understanding which ground applies to your situation is the first step in evaluating whether you have a viable claim.

Undue Influence

Undue influence occurs when someone in a position of power or trust — a caregiver, a family member, a romantic partner — pressures or manipulates the trust creator into making changes that reflect the influencer's wishes rather than the creator's own. Courts look at the relationship between the parties, the trust creator's vulnerability, and whether the change benefited the person in a position of control. Last-minute amendments that cut out longtime beneficiaries and favor a single person are among the most common patterns we see.

Lack of Capacity

A trust is only valid if the person who created or amended it had the mental capacity to understand what they were signing. This means they needed to know the nature of their assets, who their natural heirs were, and what the document actually did. If a trust was amended during a period of documented cognitive decline — dementia, a medical crisis, or heavy medication — lack of capacity may be a viable ground for contest.

What Evidence Courts Consider in a Trust Contest

Medical Records and Cognitive History

Medical documentation is often central to a capacity or undue influence claim. Records showing a diagnosis of dementia, a hospitalization, or a prescribed medication that affects judgment — particularly if timed close to when the trust was signed or amended — can be powerful evidence. We work with families to gather and present this documentation in a form Michigan courts recognize.

Witness Testimony and Circumstantial Evidence

Who was present when the trust was signed? Who drafted it, and at whose direction? Who stood to benefit from the change? These questions matter. Testimony from family members, former caregivers, neighbors, or the drafting attorney can all be relevant. Courts also consider patterns of behavior — isolation, financial dependency, sudden changes in relationship dynamics — when evaluating undue influence claims.

Prior Trust Documents and Amendment History

A trust that was amended multiple times in the final months of someone's life, with each amendment shifting more assets toward a single beneficiary, tells a story. Comparing the original trust to subsequent amendments — and documenting who requested those changes and when — is often where a contest case is built or lost.

Revocable Trusts vs. Irrevocable Trusts: Does the Type Matter?

It does. A revocable trust can generally be contested after the trust creator's death, because that is when it becomes irrevocable and its terms go into effect. Challenging a revocable trust while the creator is still alive is rarely possible — they retain the right to change it at any time. An irrevocable trust, by contrast, is locked in from the moment it is signed, which means the window for contesting it on capacity or undue influence grounds begins at execution, not at death.

What Happens If There Is a No-Contest Clause?

Many trusts include a no-contest clause — also called an in terrorem clause — that threatens to disinherit any beneficiary who challenges the trust. Michigan courts do enforce these clauses, but they will not apply them when a beneficiary had probable cause to bring the contest. In plain terms: if you had a reasonable basis to believe the trust was invalid, you will not automatically lose your inheritance for raising the question. An attorney review before you file anything is essential.

What the Contest Process Looks Like

A trust contest in Michigan is filed in probate court. The process typically begins with a petition challenging the validity of the trust or a specific amendment. The court may order discovery — the exchange of documents, depositions, and records — before any hearing. Some cases settle during this process; others proceed to a full evidentiary hearing before a probate judge. The timeline varies significantly based on the complexity of the dispute and whether the trustee contests the claim. Craig Fiederlein has litigated these matters in Genesee County Probate Court and can walk you through what to expect in your specific situation.

Who Can Contest a Trust in Michigan?

Not everyone has the legal standing to challenge a trust. In Michigan, the right to contest a trust is generally limited to interested persons — those who would be directly affected by the outcome. This typically includes:

• Beneficiaries named in the current trust
• Beneficiaries named in a prior version of the trust who were removed or had their share reduced
• Heirs at law who would inherit under Michigan's intestacy statutes if the trust were invalidated
• Creditors of the trust or estate in certain circumstances

If you are unsure whether you qualify as an interested person, that is one of the first questions we address in a consultation.

Deadlines for Contesting a Trust in Michigan

Michigan law imposes strict time limits on trust contests, and missing them can permanently bar your claim regardless of how strong your case may be. Under the Michigan Trust Code, a trust contest must generally be filed within the earlier of:

• Three years after the trust creator's death, or
• 63 days after the trustee delivers a copy of the trust and a notice of the right to contest

The 63-day window is the one that catches most families off guard. If a trustee sends formal notice — and some do so deliberately and quickly — the clock starts immediately. Do not wait to seek legal advice if you have received any communication from a trustee after a loved one's death.
