Parent Has Dementia No Power of Attorney Michigan: What to Do Next

Your parent has dementia. No one set up a power of attorney. Now you can't access their bank accounts, can't authorize medical treatment, and the nursing home wants a deposit you have no legal authority to pay. The situation feels impossible.

It may not be. Michigan law provides a narrow window — and a backup plan when that window closes.

A Dementia Diagnosis Does Not Automatically Disqualify Your Parent

This is the most common misconception families face. Under Michigan law, a diagnosis of Alzheimer's disease, vascular dementia, or any other cognitive condition does not automatically strip a person of the legal capacity to sign documents.

Capacity is evaluated functionally, at the moment of execution. Your parent can sign a valid Durable Power of Attorney if, at the time of signing, they understand:

• Who they are appointing as their agent
• What powers they are granting
• The consequences of that delegation

Many people with mild to moderate dementia experience "lucid intervals" — periods of relative cognitive clarity. If your parent has a lucid interval where they can demonstrate understanding, a POA signed during that window is legally valid.

How to Protect a Lucid Interval Signing

A POA signed during a lucid interval is vulnerable to challenge — from siblings, banks, or courts. Protect the document with these steps:

Get a contemporaneous physician's letter. Before the signing, have the parent's physician or a neuropsychologist evaluate them and document in writing that the parent understood the nature, scope, and consequences of the POA at the time of examination. Date and time-stamp the letter.

Use a notary public. Under the UPOAA (MCL 556.205), a notarized POA triggers mandatory bank acceptance within 7 business days. Notarization also creates an independent witness to the parent's apparent capacity at the time of signing.

Record video of the signing. While not legally required, video documentation of the parent demonstrating understanding provides powerful evidence against future challenges. Record them explaining who they're appointing and why.

Have the Agent's Acknowledgment signed immediately. Under MCL 556.213, the agent must sign a written acknowledgment of fiduciary duties. Completing this alongside the POA signing demonstrates a complete, orderly execution.

When Capacity Is Truly Gone

If a physician evaluates your parent and determines they can no longer understand what a POA does — even during their best moments — the voluntary path is closed. A POA signed without capacity is legally void, and attempting to execute one when the parent doesn't understand the document could trigger an Adult Protective Services investigation for financial exploitation.

When capacity is gone, your only option is petitioning the Michigan probate court for:

• Guardianship (SCAO Form PC 625) — for personal and medical decision-making authority
• Conservatorship (SCAO Form PC 639) — for financial and property management authority

The Guardianship Process for Dementia

Filing for guardianship requires clear and convincing evidence that the parent is incapacitated. For a parent with advanced dementia, this typically includes:

• A Report of Physician (SCAO Form PC 630) documenting the diagnosis and functional limitations
• Neuropsychological evaluation results if available
• Testimony from treating physicians and caregivers

The court appoints a Guardian Ad Litem to visit the parent, evaluate their condition, and file a recommendation. Total cost: $175 filing fee per petition (guardianship and conservatorship are separate petitions), plus $150–$300 for the GAL fee.

If the situation is an emergency — the parent needs immediate medical treatment no one can authorize, or their finances are at risk — request emergency temporary guardianship at the time of filing. The court can conduct an ex parte hearing within 24–48 hours, granting temporary Letters of Guardianship that last 28 days while the full process proceeds.

The Path Forward

The worst thing you can do is wait. Dementia is progressive. Every day of delay:

• Narrows the window for a lucid interval signing
• Leaves your parent's bank accounts and home unprotected
• Exposes the family to the full cost and complexity of probate court

If your parent still has any periods of lucidity, act now. A physician evaluation and a properly witnessed POA signing can prevent months of court proceedings and thousands of dollars in legal fees.

The Michigan Power of Attorney & Guardianship Kit includes both pathways: the lucid interval POA signing protocol with physician letter templates and witness screening checklists, plus the full guardianship filing sequence with form-by-form instructions for when court intervention is the only option.
