Michigan Supported Decision-Making vs Guardianship

Guardianship strips your adult child of the legal capacity to make fundamental choices about their residence, healthcare, relationships, and finances. It's court-ordered, it's expensive, and Michigan law explicitly requires it to be a last resort for individuals with developmental disabilities. Yet many families still pursue full guardianship as a reflexive "turning 18" step — often because they don't know the alternatives exist.

Michigan's SDM Legislation: Where Things Stand

House Bills 4676 and 4677 were introduced in June 2025 to formally recognize Supported Decision-Making as a legal alternative to guardianship in Michigan. The bills would amend both the Mental Health Code and the Estates and Protected Individuals Code (EPIC), requiring probate courts to evaluate less-restrictive alternatives — SDM, powers of attorney, representative payees, trusts — before appointing a guardian.

On August 13, 2025, the House Families and Veterans Committee reported both bills with a unanimous 10-0 recommendation. As of early 2026, they're pending floor votes in the full legislature.

What SDM Looks Like in Practice

Under Supported Decision-Making, your adult child retains full legal authority. They choose a network of trusted supporters — parents, siblings, advocates, service coordinators — who help them gather information, understand options, and communicate decisions. The individual makes the final call.

Michigan has no enacted SDM statute yet, but probate courts have increasingly recognized SDM agreements on a case-by-case basis. The landmark VanWormer rulings demonstrated that courts will approve SDM as a less restrictive alternative when the supporting documentation is well-structured.

To implement SDM without a statute, draft a detailed Supported Decision-Making Agreement specifying who the supporters are, what domains they help with (medical, financial, housing, daily life), and how the process works. Because many Michigan financial institutions and medical providers aren't familiar with SDM, have the agreement signed before a licensed notary public to improve institutional acceptance.

The Full Decision-Making Spectrum

SDM sits at the least-restrictive end of a continuum:

Supported Decision-Making — the individual retains all legal rights; supporters assist but don't substitute. No court involvement required.

Durable Financial Power of Attorney — the individual (principal) designates a trusted person (agent) to manage financial transactions. Can be revoked anytime. Requires signing capacity at the time of execution.

Designation of Patient Advocate — Michigan's medical power of attorney, granting a designated advocate authority to make medical decisions if the individual is unable to provide informed consent. Also requires signing capacity.

Representative Payee — the SSA designates a parent or caregiver to receive and manage SSI or DAC checks directly. Administrative designation through SSA, not a probate court proceeding.

Guardianship — court-ordered removal of legal rights. Under Michigan's Mental Health Code, guardianship for individuals with developmental disabilities must be utilized only as necessary, must account for the individual's specific abilities, and must promote maximum self-reliance and independence.

When Guardianship Is Still Appropriate

SDM works when your adult child can participate meaningfully in decision-making with support. If guardianship is necessary, its scope should be tailored to the individual's specific abilities and limited to the authority that is necessary.

Consult a special needs attorney about the appropriate probate petition under the Mental Health Code.
