How to Choose Between SDM, Power of Attorney, and Guardianship in Wisconsin
If you're trying to decide between a Supported Decision-Making agreement, Powers of Attorney, and guardianship for your child turning 18 in Wisconsin, start with this principle: Wisconsin circuit courts are required under § 54.10(3)(a)4 to consider less-restrictive alternatives before granting guardianship. The court will ask whether you evaluated SDM and POA options first. So the question isn't "should I get guardianship?" — it's "what level of legal authority does my child actually need, domain by domain?"
The answer depends on your child's functional capabilities in four areas: medical decision-making, financial management, educational choices, and residential decisions. Each area maps to a specific legal tool. Many families need a combination of tools, not a single one.
The Decision Framework: Domain by Domain
The mistake most families make is treating this as a single binary choice — guardianship or not. Wisconsin law offers a spectrum, and the right answer is usually a combination that matches your child's capability profile.
| Decision Domain | Your Child Can Participate With Support | Your Child Cannot Participate Meaningfully |
|---|---|---|
| Medical consent | Healthcare POA (Chapter 155) — agent authority activates only when two physicians (or one physician and one advanced practice clinician) personally examine the principal and sign a written finding of incapacity | Guardianship of the person — guardian consents to treatment on an ongoing basis |
| Financial management | Financial POA (Chapter 244) — agent manages accounts alongside the individual | Guardianship of the estate — guardian has sole financial control |
| Educational decisions | FERPA consent form + SDM agreement — parents access records and attend IEP meetings as supporters | Guardianship of the person — guardian directs educational decisions |
| Residential choices | SDM agreement — supporter helps evaluate options, individual makes final choice | Guardianship of the person (and potentially protective placement under Chapter 55 if safety requires it) |
The key question for each domain: Can your child understand the decision being made and communicate a preference, even with support? If yes — even if their judgment isn't perfect — the less-restrictive tool applies. If no, that specific domain may require guardianship authority.
Option 1: Supported Decision-Making Agreement (Chapter 52)
What it does: Your child names trusted supporters who help gather information, attend meetings, and communicate decisions — but the supporter never makes the decision. Your child retains full legal capacity and all civil rights.
When it's the right choice:
- Your child can understand that they're choosing someone to help them make decisions
- They can communicate preferences (verbally, through AAC, through behavior patterns that supporters can interpret)
- Their challenges are about processing complex information, not about the ability to have preferences at all
- You need help navigating institutions (hospitals, banks, schools) that want to see a formal document before talking to parents
When it's not enough:
- Your child cannot meaningfully participate in the concept of choosing a supporter
- There's a realistic risk of financial exploitation that the supporter can't prevent (because the supporter can't void contracts or block transactions)
- Emergency medical situations where the individual can't communicate and the hospital needs someone with actual decision-making authority, not just a support role
- The individual has signed or would sign harmful financial agreements that an SDM supporter cannot unilaterally undo
Execution: The agreement uses DHS Form F-02377, must be voluntary, written, and signed before either a notary public or two adult witnesses who aren't the designated supporters. It can be modified or revoked at any time. No court involvement.
Option 2: Powers of Attorney (Chapters 155 and 244)
What they do: Your child delegates actual decision-making authority to an agent — for healthcare (Chapter 155), finances (Chapter 244), or both. Unlike an SDM supporter, a POA agent can sign documents, consent to treatment, and manage accounts on your child's behalf.
When they're the right choice:
- Your child has the cognitive capacity right now to understand what they're signing (this is a legal requirement — a POA signed by someone who lacks capacity is voidable)
- You need actual authority, not just a support role — the ability to consent to surgery, manage a bank account, sign a lease
- The Healthcare POA gives you a safety net for medical emergencies without removing your child's day-to-day medical autonomy (it's typically "springing" — the agent's authority activates only when two physicians (or one physician and one advanced practice clinician) personally examine the principal and sign a written finding of incapacity)
- The Financial POA lets you manage benefits applications, bank accounts, and bills while your child retains the legal right to manage their own finances too
When they're not enough:
- Your child does not have the current capacity to understand and sign a POA (you can't execute a POA on behalf of someone who can't consent to it)
- You need residential placement authority that a financial agent doesn't have
- The individual actively resists having an agent and there's no way to obtain voluntary consent
- The risk is so high (severe self-harm, extreme financial vulnerability) that you need the court's supervisory authority, not just a private contract
Execution: Healthcare POA requires the principal to sign in the presence of two adult witnesses or a notary public. Financial POA can be deposited with the county Register in Probate for $8.00. Both are private contracts — no court involvement. Both can be revoked by the principal at any time they have capacity.
The layering strategy: Many Wisconsin families combine an SDM agreement with one or both POAs. The SDM covers daily decision support. The Healthcare POA activates only in incapacity emergencies. The Financial POA handles benefits management and banking. Together, they cover most domains without court involvement.

Option 3: Limited Guardianship
What it does: A circuit court transfers specific, delineated decision-making powers to a guardian while the individual retains all other rights. Under § 54.25(2)(d)1, the court order must specify exactly which powers the guardian holds.
When it's the right choice:
- Your child cannot sign a POA due to capacity limitations
- SDM is insufficient because the individual cannot meaningfully participate in choosing a supporter
- But your child has real capabilities in some domains — they can make daily choices, express preferences about where to live, participate in their community — and stripping all rights through full guardianship would remove autonomy they actually exercise
- You want court oversight to protect against exploitation, but you want the court to preserve every right your child can exercise
When it's not the right choice:
- Your child can sign a POA (use the less-restrictive option)
- Your child functions independently in all domains with SDM support (no court needed)
- Your child has no meaningful decision-making capability in any domain (full guardianship may be more appropriate)
Execution: File Form GN-3100 in probate court (can be filed at age 17 years, 9 months). Obtain the Examining Physician's Report (GN-3130) filed 96 hours before the hearing. Complete the mandatory UW-Green Bay training (free, self-paced). The court appoints a Guardian ad Litem. If uncontested, the process typically takes 30–90 days. GAL deposits vary by county: $200 in smaller counties, $2,000 in Waukesha County.
Option 4: Full Guardianship
What it does: Transfers comprehensive decision-making authority to the guardian across all domains — medical, financial, educational, residential. The individual loses the legal right to make independent decisions unless the court specifically preserves certain rights.
When it's the right choice:
- Your child has profound cognitive disabilities that prevent meaningful participation in any decision-making domain
- Less-restrictive alternatives have been evaluated and genuinely don't fit (the court will ask)
- There's a serious and documented risk of harm, exploitation, or inability to meet basic needs without full guardian authority
- The situation requires the court's ongoing supervisory framework (annual reporting, inventory filing, modification procedures)
When it's more than what's needed:
- Your child functions independently in some domains — even one area of capability argues for limited guardianship
- The primary concern is medical consent or financial management, which POAs can address
- The family wants the "security" of guardianship without a specific, documented need that can't be met by a less-restrictive tool
The rights reality: Full guardianship can strip the right to vote (only with a specific individualized court finding under § 54.25(2)(c)1), the right to marry, and the right to make any independent legal decisions. Advocacy organizations report that courts sometimes check the box to remove voting rights without conducting a rigorous evaluation. If you pursue full guardianship, explicitly request that the court preserve every right your child can exercise.
The Decision Sequence
Start with capability evaluation. Assess your child's functional decision-making in each of the four domains. Use the school's transition assessment data, medical evaluations, and your own observations.
Try the least restrictive tool first. If your child can participate in decisions with support, draft an SDM agreement. If they can sign a POA, execute POAs for the domains that need delegated authority.
Layer tools where needed. SDM for daily support + Healthcare POA for medical emergencies + Financial POA for benefits management covers most situations without court involvement.
Go to court only when the non-court tools don't fit. If your child can't sign a POA, can't meaningfully participate in an SDM, or faces risks that private contracts can't address, petition for the most limited guardianship that meets the documented need.
Document everything. The court will want to see that you evaluated alternatives. The capability evaluation worksheets in the Wisconsin Adult Guardianship & Alternatives Guide create this documentation systematically.
Who This Is For
- Parents who received the DPI Forms M-7/M-8 transfer-of-rights notice and need a structured way to evaluate their child's options
- Families whose child has capabilities in some domains but not others, making a single-tool answer inadequate
- Parents being told by schools, doctors, or family members to "just get guardianship" who suspect that's more restriction than their child needs
- Families approaching the 18th birthday who need to decide and execute within months
Who This Is NOT For
- Families whose child has full decision-making capacity — no legal framework is needed beyond the normal transfer of adult rights
- Situations where a court has already appointed a guardian and the question is modification or termination (that's a different process under § 54.64)
- Cases involving active abuse or neglect — contact Adult Protective Services, not a planning guide
Frequently Asked Questions
Can I combine an SDM agreement with Powers of Attorney?
Yes, and this is the most common layered approach. The SDM agreement covers daily decision support, the Healthcare POA activates only during incapacity emergencies, and the Financial POA handles benefits management and banking. Each tool addresses a different gap, and together they often eliminate the need for court involvement.
What if my child can sign a POA now but might lose capacity later?
Execute the POA while your child has capacity. A properly drafted Healthcare POA is typically "springing" — the agent's authority activates only when two physicians (or one physician and one advanced practice clinician) personally examine the principal and sign a written finding of incapacity. The Financial POA can be structured to activate upon a defined trigger, typically a clinical incapacity determination. If capacity declines further, the POAs remain in effect. If it declines to the point where the POAs are insufficient, you can petition for guardianship at any time — there's no age deadline after 18.
Does the court really require evidence that I considered alternatives?
Yes. Under § 54.10(3)(a)4, the circuit court must consider less-restrictive alternatives before appointing a guardian. The Guardian ad Litem's report typically addresses whether alternatives were explored. Coming to court with documentation that you evaluated SDM, POA options, and other tools — and specific reasons they don't fit — strengthens your petition significantly.
My child has autism and is very capable in some areas but not others. Which option fits?
This is exactly the profile where a domain-by-domain evaluation matters most. An autistic young adult who manages daily routines independently but struggles with financial exploitation might need only a Financial POA — not guardianship. One who communicates preferences clearly but can't evaluate complex medical options might need a Healthcare POA layered with an SDM. The guide's capability evaluation worksheets walk through each domain separately rather than treating capability as all-or-nothing.
How quickly can I set up SDM and POA if the 18th birthday is close?
SDM agreements and Powers of Attorney can be executed in days — they're private contracts that need a notary or two witnesses, not court approval. If the 18th birthday is weeks away and your child has capacity to sign, these are the fastest options. Guardianship petitions, by contrast, typically take 30–90 days for the court process.
What happens if I choose wrong?
Every option on this spectrum is modifiable. An SDM agreement can be revoked and replaced. Powers of Attorney can be revoked (by the principal, if they have capacity). Guardianship can be modified or terminated under § 54.64 when the individual's abilities develop. The real risk isn't choosing wrong — it's choosing more restriction than necessary, because courts are more willing to grant guardianship than to terminate it later.
