How to revoke a power of attorney in Michigan
What Michigan law says about revoking a power of attorney, and a free letter you can fill in and print.
Checked against official sources: October 31, 2026.
Short answer
You can revoke the power of attorney, or one agent's authority, while you have capacity. The act does not prescribe a method; a signed written revocation sent to the agent and to anyone who has the power of attorney is the clearest record.
Words used in Michigan
In Michigan you name an agent for money and property in a power of attorney, and a patient advocate for medical and mental health decisions in a separate patient advocate designation. Michigan has no statute for living wills; written wishes can be put in the patient advocate designation. If an adult cannot decide and has no documents, the probate court can appoint a guardian (for personal decisions) or a conservator (for money).
An agent (also called an attorney-in-fact) is the person you choose to act for you. You are the principal.

What Michigan law says about revoking a power of attorney
- How to revoke
You can revoke the power of attorney, or one agent's authority, while you have capacity. The act does not prescribe a method; a signed written revocation sent to the agent and to anyone who has the power of attorney is the clearest record. Signing a new power of attorney does not revoke an older one unless the new one says so.
- Telling others
Tell the agent and give copies to banks and others who have the power of attorney. An agent or other person who acts in good faith without actual knowledge of the revocation is protected, and those acts bind you.

A person asked to accept a notarized (acknowledged) power of attorney must accept it, or ask for the agent's acknowledgment, a certification, a translation or a lawyer's opinion, within 7 business days, and then accept within 5 business days after getting what they asked for. They cannot demand their own form. They may refuse only for listed reasons, for example a good faith belief the power is invalid, a report to adult protective services, or a freeze under the Financial Exploitation Prevention Act. A wrongful refusal can lead to a court order and payment of attorney fees and costs.
