Guardianship vs. Power of Attorney in Michigan: What Families Need to Know

There's a moment a lot of families don't see coming until it's already on top of them. A parent has a stroke, or dementia crosses a line, and suddenly there are decisions to make (about money, about medical care, about where they'll live) and no one is quite sure who has the legal right to make them.

In Michigan, the answer to "who decides" comes down to one thing more than any other: what was put in place before that moment arrived. Get it set up early, and a family handles things quietly around the kitchen table. Miss the window, and the same decisions can require a judge.

We're not attorneys, and this isn't legal advice. But we've watched enough families go through both versions to know how much smoother one is than the other. Here's the difference.

Two Ways Someone Can Act for Another Adult

When an adult can no longer make sound decisions for themselves, Michigan law offers two broad paths for someone else to step in.

The first is planned ahead of time, by the person themselves, through power of attorney documents. The second is ordered by a court, after the fact, through guardianship and conservatorship. The first is private, inexpensive, and entirely in your family's control. The second is public, slower, costs more, and puts a probate judge in the middle of your decisions.

That contrast is the whole point of this article.

Power of Attorney: Deciding in Advance

A power of attorney is a document your parent signs while they still have the capacity to understand it, naming someone they trust to act for them. There are two kinds that matter most for senior care.

A durable power of attorney handles financial and legal matters: paying bills, managing accounts, dealing with property. The word "durable" is the important part: an ordinary power of attorney ends the moment a person becomes incapacitated, which is exactly when you need it most. A durable one keeps working. In Michigan this is governed by the Estates and Protected Individuals Code (EPIC, MCL 700.5501 and following), and the state replaced those rules under the Uniform Power of Attorney Act, which took effect in 2024.

The second is the Patient Advocate Designation, which is Michigan's name for a healthcare power of attorney (MCL 700.5506 and following). This names the person who can make medical decisions if your parent can't speak for themselves. We've written a separate post on the Patient Advocate Designation and the related MI POST form, because medical decision-making deserves its own walk-through, but know that it pairs with the financial document. You generally want both.

Here's the key feature of all of this: your parent stays in charge. Signing a power of attorney doesn't take anyone's rights away. It simply names a backup who can act when needed. And because your parent chose that person and signed willingly, there's no court, no hearing, no judge: just the documents, ready when the family needs them.

Guardianship: When the Court Has to Step In

Now the other path. If a parent loses the ability to make decisions and there's no valid power of attorney in place, the family can't simply take over. No one, not even a spouse or an adult child, has automatic legal authority over another adult's affairs.

To get that authority, someone has to petition the probate court. A judge then has to find that the person is a "legally incapacitated individual" under Michigan law, and only then appoint a guardian to make decisions about the person: where they live, their medical care, their daily welfare. If there's property and money to manage, that's a separate appointment, a conservator, over the person's finances.

Michigan treats guardianship as a last resort, used only when there's no less-restrictive alternative available, which is precisely why having powers of attorney in place usually avoids it. The court process takes time, often involves a hearing and a court-appointed evaluator, costs money, and doesn't end at the appointment. A guardian and conservator typically answer to the court with ongoing reports for as long as the arrangement lasts.

None of that means guardianship is bad. Sometimes it's genuinely necessary: when no documents were ever signed, when there's family conflict, when someone is being financially exploited. The probate court exists to protect vulnerable people, and it does. It's just a heavier, slower, more public tool than the one most families would choose if they'd had the chance to choose.

Why Timing Is Everything (Especially with Dementia)

Here's the part we most want families to take away. A power of attorney can only be signed by someone who still understands what they're signing. Once dementia advances past a certain point, that window closes. After that, the power of attorney is off the table, and guardianship through the court becomes the only road left.

That's why the early stage of a dementia diagnosis, while your parent can still take part, is the time to get these documents done. We've written before about the stages of dementia and how the early stage is the planning window for exactly this reason. Families who use that window get to keep these decisions at home. Families who wait often find themselves in a probate courtroom a year or two later, doing the hard way what could have been done with a signature.

If your parent is healthy, this is the boring, easy version: sit down with an estate planning or elder law attorney and get a durable power of attorney and a Patient Advocate Designation in place. It's not expensive, and it's one of the kindest things a family can set up before it's needed.

The Bottom Line

A power of attorney is something your parent gives, in advance, to someone they trust. Guardianship is something a court imposes, after the fact, when nothing was given. Both end up serving the same purpose, letting someone make decisions for a person who no longer can, but the difference in cost, control, and stress between them is enormous, and it all turns on timing.
