How to Get Legal Authority Over a Grandchild in Wisconsin After Providing Informal Care

If you have been raising your grandchild informally in Wisconsin — the child lives with you, you feed them, get them to school, take them to the doctor — and you have reached the point where a school, hospital, or benefits office is telling you they need something official, you have three paths to legal authority. Which one fits depends on whether the parent is available and willing to sign paperwork, how long you need the authority, and whether you need it recognized by a court.

The fastest option is a Parental Power of Attorney (Form GF-223), which a parent with legal custody can sign without going to court; both parents must sign if they share legal custody. If the parent is unavailable, uncooperative, or you need permanent authority, you can petition for guardianship under Wis. Stat. § 48.9795 in the proper county's circuit court. A parent's consent or absence does not by itself guarantee appointment; the court must find the statutory grounds and best interests of the child. Chapter 767 allows custody to be decided as part of an action affecting the family or in an independent custody action.

Wisconsin does not have a "de facto custodian" statute. Unlike Kentucky, Indiana, or South Carolina, you cannot establish automatic legal standing simply by proving you have been the child's primary caregiver for a specific period. No matter how long the child has lived with you, you must go through one of the formal routes below.

Three Paths to Legal Authority

Path 1: Parental Power of Attorney — No Court Required

If the child's parent is reachable and willing to sign, Form GF-223 (Power of Attorney Delegating Parental Power under § 48.979) can delegate educational and medical decision-making authority. It lasts one year by default; a relative agent can receive a longer term without court approval. A parent with legal custody can revoke it in writing at any time; both parents must sign if they share legal custody.

This works when:

• The parent is going into treatment, deploying, or temporarily unable to care for the child
• You need the school to accept enrollment or the pediatrician to treat the child without delay
• The arrangement is genuinely temporary and the parent is cooperating

Court approval is required if: the child is under juvenile court jurisdiction, the child is an Indian child under ICWA/WICWA, or a non-relative agent will serve longer than one year.

The Power of Attorney does not give you authority to consent to termination of parental rights, and it does not qualify you for Kinship Care financial benefits that require a court order or county placement.

Path 2: Guardianship — The Court Route

When a parent is not available to sign a GF-223, or you need authority that a parent cannot revoke on a whim, guardianship under § 48.9795 is one court route. You file a petition (Form JN-1501) in the circuit court of the child's county of residence or physical presence, or, if the child is a nonresident, the county where you propose the child will reside.

Types of guardianship available:

• Full guardianship — when parents are unfit, unwilling, or unable to provide care, custody, and control, or other compelling facts and circumstances show full guardianship is necessary. The petition's allegations must be proven by clear and convincing evidence. It lasts until age 18.
• Limited guardianship — when parents need help with specific aspects of care. The court order spells out exactly what authority you have; everything else stays with the parents.
• Temporary guardianship — for short-term situations. Up to 180 days, extendable once for another 180 days (360 days maximum).
• Emergency guardianship — when the child's welfare requires immediate appointment. Filed on Form JN-1504. Up to 60 days. For good cause, the court may issue a temporary order without a hearing until it holds the petition hearing; notice is given as soon as possible by the most practical means.

What the filing involves:

1. File the petition (JN-1501) with the UCCJEA declaration (GF-150)
2. File the Statement by Proposed Guardian (JN-1514) at least 96 hours before the initial hearing
3. Serve every parent and other required parties at least 7 days before the hearing (for full, limited, or temporary guardianship)
4. The court appoints a Guardian ad Litem to represent the child's interests
5. Attend the hearing, where the judge evaluates the child's best interests
6. If granted, obtain certified copies of the Letters of Guardianship (JN-1530) and notify schools, medical providers, and benefit agencies

Background checks: Wisconsin requires a background check for the proposed guardian. The court or GAL typically initiates this through the Department of Justice Criminal Background Check (Form DJ-LE-250) or the county's process.

Path 3: Third-Party Custody — Narrow but Powerful

Chapter 767 allows custody to be determined as part of an action affecting the family or in an independent custody action. When a nonparent seeks custody over a parent's objection, the Barstad v. Frazier standard requires parental unfitness or inability, or compelling reasons, as well as the child's best interests. You cannot win simply by showing the child would be better off with you.

A guardianship petition under § 48.9795 is another route for kinship caregivers. An existing divorce or paternity case is not required for every independent custody action.

Who This Is For

• Grandparents or relatives who have been caring for a child informally — days, weeks, or years — and now face an institutional demand for legal documentation
• Caregivers told by a school that they cannot enroll the child, or by a doctor that they cannot authorize treatment, without legal authority
• Relatives whose benefits applications (Kinship Care, BadgerCare Plus, FoodShare) are stalled because the county requires a court order or formal placement documentation
• Informal caregivers who are not sure whether they need a court order or whether a Power of Attorney would be enough

Who This Is NOT For

• Parents seeking to designate a temporary caregiver — you are the signer of Form GF-223, not the recipient of this guidance
• Foster parents or kinship foster parents placed through DCF or a county child welfare agency — your authority comes through the agency and CHIPS proceedings, not a private guardianship petition
• Anyone trying to remove a child from a parent's home over the parent's objection without court involvement — that requires a court order

Common Mistakes Informal Caregivers Make

Waiting too long. Many grandparents provide care informally for years, hoping the parent will stabilize. By the time the school or doctor forces the issue, the situation is urgent and the filing feels overwhelming. Starting the process while things are stable gives you more options and less pressure.

Assuming CPS involvement equals a court order. Contacting child protective services or the Department of Children and Families does not automatically give you legal custody or guardianship. CPS investigates child safety; the circuit court grants guardianship. They are separate systems.

Filing the wrong type of guardianship. Temporary guardianship maxes out at 360 days. If the parent's situation is not going to resolve in that window, you may need full guardianship from the start. Conversely, if the parent is in a 90-day treatment program and expects to resume care, temporary guardianship addresses the parent's temporary inability to provide care. The petition's allegations still must be proven by clear and convincing evidence.

Skipping the UCCJEA declaration. Every guardianship petition must include Form GF-150, even if the child has lived in Wisconsin their entire life. Courts reject petitions that omit it.

Frequently Asked Questions

How long does it take to get guardianship of a grandchild in Wisconsin?

For full, limited, or temporary guardianship, the initial hearing must be held within 45 days after filing. If the petition is uncontested, the court proceeds to fact-finding and disposition at that hearing unless an adjournment is requested. Emergency petitions are heard as soon as possible; for good cause, the court may issue a temporary order without a hearing until the petition hearing.

Can I enroll my grandchild in school without guardianship in Wisconsin?

If the parent signs a Parental Power of Attorney (Form GF-223), that may be enough for school enrollment and medical consent. If no parent is available to sign, some school districts accept a caregiver affidavit for temporary enrollment under the McKinney-Vento Act if the child qualifies as homeless or in transition. For lasting enrollment authority, guardianship provides the clearest legal basis.

Does Wisconsin recognize informal custody arrangements?

No. Wisconsin has no de facto custodian statute and does not grant legal rights based on duration of informal care alone. You must obtain legal authority through one of the three formal routes: Power of Attorney, guardianship, or third-party custody.

What if I cannot find the child's parent to serve the guardianship papers?

Document your search efforts, including checks of known addresses, relatives and friends, public records, and Department of Corrections records if the parent may be incarcerated. For a non-Indian child, the petition and hearing notice must be sent by certified mail to the parent's last-known address unless the court waives notice for good cause; the court may require publication when no address is known. Indian-child cases have separate notice rules.

Can I get Kinship Care payments without a court order?

Wisconsin's Kinship Care program has specific eligibility criteria administered by county human services departments. Some benefits require a court order or formal county placement, while others may be available to informal caregivers who meet other criteria. The companion Wisconsin financial help guide covers the full program-by-program details.
