Supported Decision Making in Wisconsin: How It Works Under Chapter 52
What Supported Decision-Making Actually Means in Wisconsin
When a young adult with a disability turns 18, Wisconsin law presumes them competent to manage their own affairs — regardless of their cognitive abilities. Parents lose the legal authority to make medical, financial, or educational decisions overnight.
Many families immediately think about guardianship. But guardianship can limit the adult's legal rights, requires a court proceeding, costs thousands of dollars, and may not be necessary.
Wisconsin offers a middle ground under Chapter 52 of the state statutes: the Supported Decision-Making Agreement. This document lets an adult with a disability choose one or more trusted "supporters" to help them gather information, understand options, and communicate their own decisions — without surrendering their legal autonomy.
How the Agreement Works
The SDM Agreement uses DHS Form F-02377. The adult (called the "principal") designates one or more supporters and specifies the areas of life where they want help — healthcare, finances, housing, employment, or any combination.
The supporter does not make decisions for the principal. They help the principal access information, weigh options, and express choices. The supporter has no legal authority to sign contracts, consent to medical treatment, or manage bank accounts on the principal's behalf.
Two requirements: the agreement must be signed voluntarily by both the principal and each supporter, and witnessed by two adults or a notary public.
SDM vs. Guardianship: What Families Should Consider
Full guardianship in Wisconsin requires a circuit court petition, medical documentation, a hearing, and often attorney fees ranging from $2,000 to $4,000 or more. Once granted, the guardian makes decisions in place of the individual — the adult's own legal capacity is formally limited.
An SDM Agreement uses a state form, requires no court involvement, and leaves the adult's legal rights fully intact. It can be revoked by the principal at any time.
The trade-off: an SDM Agreement does not force third parties to comply. A bank, hospital, or landlord is not required to consult with the supporter before interacting with the principal. Guardianship, by contrast, gives the guardian legal standing that institutions must recognize.
For many adults with intellectual or developmental disabilities, the SDM Agreement handles the day-to-day reality — helping them understand a lease, navigate a medical appointment, or manage their SSI — without the legal overhead of guardianship. If a specific situation requires binding authority (a complex medical procedure, a legal dispute), families can pursue limited guardianship for that domain while leaving the rest under SDM.

SDM and Representative Payee: Different Roles
A common point of confusion: an SSI representative payee and an SDM supporter serve different functions, and one does not replace the other.
The representative payee is appointed by the Social Security Administration to manage SSI cash benefits — ensuring the money covers food, shelter, clothing, and medical care. The payee has authority over SSA funds specifically, but no power of attorney over other finances or legal matters.
An SDM supporter helps the adult make decisions broadly but has no authority to manage money or sign on their behalf.
A parent can serve as both representative payee and SDM supporter. But the roles are separate — being named in the SDM Agreement does not grant payee authority, and being appointed representative payee does not give the parent decision-making support rights outside of SSA benefits.
When to Set This Up
Execute the SDM Agreement close to or on the 18th birthday. Do not wait for a crisis to decide between SDM and guardianship.
The IEP transition team should be discussing legal decision-making starting at age 17. Family Voices of Wisconsin and the Wisconsin Board for People with Developmental Disabilities both publish plain-language guides to SDM that can be shared at IEP meetings.
The Wisconsin SSI at 18 & Adult Disability Benefits Guide covers both SDM setup and representative payee appointment as part of the age-18 transition timeline, with checklists for each.
