Raising a Grandchild in Wisconsin Without Custody: The Paperwork You Actually Need

You took in your grandchild because someone had to, and now you're finding out that "just being grandma" doesn't open doors at the school office or the pediatrician. Wisconsin gives you more options than most people realize — without going to court.

The Three Things You Need to Handle Right Away

When a grandchild comes to live with you, three needs are immediate: school, medical care, and health insurance. Each has its own paperwork path in Wisconsin, and none of them requires a custody order.

School enrollment is the easiest. Under Wis. Stat. § 121.77, your grandchild generally has the right to attend the public school in the district where they live, unless they live there solely to attend that district's schools. That's your district now. You bring proof of your address (utility bill, lease), the child's immunization records if you have them, and prior school records if available. No court order. No power of attorney. No guardianship. The Thayer doctrine — a Wisconsin Supreme Court precedent — confirms that a child's educational residence is where the child actually lives, unless the child lives there solely to attend that district's schools.

Medical consent is where you need parental cooperation. Wisconsin does not have a self-executing caregiver affidavit. To consent to routine medical and dental care, you need Form GF-223 — a Power of Attorney Delegating Parental Power under Wis. Stat. § 48.979 — signed by every parent who holds legal custody. If the child's parent is willing to sign, this form gives you authority for doctor visits, dental care, prescriptions, immunizations, and school health permissions for up to one year (renewable, with no year limit for relatives).

Health insurance through BadgerCare Plus evaluates only the child's financial circumstances, not yours. Many children in kinship care qualify for child-only Medicaid regardless of your income. Apply through your county's Income Maintenance agency or online at access.wisconsin.gov.

What Form GF-223 Covers (and Doesn't)

A signed GF-223 lets you handle the daily operations of raising the child: doctor appointments, dental visits, school enrollment decisions, field trip permissions, emergency contacts, IEP and Section 504 meetings, and medication authorization at school. A relative caregiver who lives with the minor may qualify to sign as a Wisconsin DMV sponsor; parental delegation of driver sponsorship uses the separate DMV Form MV 3627.

It does not give you legal custody. The parent still holds their parental rights and can override your decisions or revoke the delegation at any time. It also cannot authorize consent to marriage, adoption, abortion, military enlistment, or placement in a foster or group home.

For relatives (grandparents, aunts, uncles, siblings, first cousins, step-parents), a GF-223 can run longer than one year without court approval unless a filing trigger applies, such as juvenile court jurisdiction or the child's status as an Indian child under applicable law. Non-relatives face a stricter one-year limit and must petition the court to extend.

Financial Help You Might Not Know About

Wisconsin's Kinship Care program pays a monthly rate to eligible relatives under voluntary or court-ordered Kinship Care. As of January 2026, the base rate is $384 per month per child. This is separate from foster care — it's specifically for relatives. Contact your county Department of Human Services to ask whether the child's situation qualifies for voluntary or court-ordered Kinship Care.

Even without a formal placement, you can apply for:

• BadgerCare Plus for the child's health coverage
• FoodShare (Wisconsin's SNAP program); whether the child is included in your assistance group or evaluated separately depends on household meal-preparation arrangements
• Wisconsin Shares child care subsidy if you're working and need care for a younger child
• Free or reduced-price school meals through the National School Lunch Program, subject to program eligibility

When You Might Need Court Guardianship

A GF-223 works well when the parent cooperates. When they don't — or can't be found — you'll eventually need more. If the parent refuses to sign, if the medical needs escalate beyond what a GF-223 covers, or if you need long-term legal authority over education, health, and placement, court guardianship under Wis. Stat. § 48.9795 becomes the right path.

Court guardianship doesn't require the parent's consent. It does require proving that the parent is unfit, unable, or unwilling to care for the child. Legal Action of Wisconsin and Judicare Legal Aid offer free representation to income-eligible caregivers for guardianship petitions.
