Kinship and Grandparent Adoption in Wisconsin: Securing Permanent Legal Parentage

Current as of: October 6, 2026 Adoption Law Wisconsin
Adopting a relative in Wisconsin provides a child with permanent stability when biological parents are unfit or unavailable. Relatives, such as grandparents and aunts, often qualify for a waiver of the rigorous home study requirement, making the process smoother and more affordable.

When a family is struck by tragedy-whether it is due to severe addiction, incarceration, unfitness, or the sudden death of a parent-grandparents, aunts, and uncles often step in to raise the children. While taking in a relative is an act of deep love, simply having the child live in your home does not give you legal authority. Without permanent legal status, you cannot make major medical decisions, enroll the child in certain schools, or protect them if an unfit parent suddenly demands them back.

Wisconsin law provides a structured pathway for relatives to adopt, transforming temporary care into permanent legal parentage. Navigating the family courts, particularly when terminating biological rights, is emotionally and procedurally exhausting. We highly encourage you to find a compassionate family law attorney in our directory to guide your family through this delicate transition.

Step-by-Step Process in Wisconsin

A kinship adoption involves permanently severing the legal ties of the biological parents and transferring those rights entirely to the relative. The courts take this incredibly seriously.

Step 1: Terminating Biological Parental Rights (TPR)

Before any adoption can happen, the child must be legally free to be adopted. This means the biological parents must either voluntarily surrender their rights or have them involuntarily terminated by a judge. You must file Form JC-1630, Wisconsin, Circuit Court, Petition for Termination of Parental Rights. Under Wis. Stat. § 48.42, involuntary TPR can be granted if the parent has abandoned the child, failed to assume parental responsibility, or suffers from severe, ongoing unfitness. The Wisconsin courts have upheld strict standards for TPR, as seen in In re Interest of Brandon S.S., 179 Wis. 2d 114 (WI Supreme Court 1993), which emphasizes that termination must strictly align with the child's best interests.

Step 2: Grandparents vs. Aunts/Uncles Adopting

The state has specific rules regarding who is considered a relative. Under Wis. Stat. § 48.02, relatives include grandparents, great-grandparents, aunts, uncles, and adult siblings. Whether you are a grandparent or an aunt, your legal standing to file a relative adoption petition is the same, though the court will closely examine your age, health, and ability to provide long-term care for the child.

Step 3: Waiving the Standard Home Study

Typically, anyone adopting a child must undergo an expensive and invasive six-month home study process. However, Wisconsin law offers a massive advantage for kinship adoptions. Under Wis. Stat. § 48.835, the court has the authority to waive the standard agency home study requirement for qualifying relatives. Instead, the court may order a much simpler, faster background screening, saving you significant time and money.

Step 4: Filing for Adoption

Once TPR is granted, you will file Form JC-1645, Wisconsin, Circuit Court, Petition for Minor Child Adoption at your local courthouse, such as the Brown County Circuit Court, Green Bay or the Waukesha County Circuit Court, Waukesha. The judge will schedule a final hearing to ensure the placement is safe, secure, and permanent.

Contested Kinship Adoptions vs. Subsidized Guardianship

If a biological parent fiercely contests the TPR, litigation can become brutal and expensive. If terminating their rights proves too difficult or emotionally damaging, you may opt for guardianship instead. A legal guardianship grants you the authority to raise the child and make legal decisions, but it does not permanently sever the biological parent's rights. Additionally, if the child was placed with you through the foster care system via the Wisconsin Department of Children and Families, Madison, you might qualify for Subsidized Guardianship, providing you with monthly financial assistance to help care for the child.

How Much Does it Cost in Wisconsin?

Costs vary widely depending on whether the biological parents fight the process.

  • Court Fees: Under Wis. Stat. § 814.61(1)(c)4 and Wis. Stat. § 814.61(1)(c)5, Wisconsin waives statutory court filing fees ($0) for petitions to terminate parental rights and adopt a minor child. Petitioners are typically only responsible for a mandatory $35 eFiling fee under Wis. Stat. § 758.19(4m) and Wis. Stat. § 801.18(7).
  • Background Screenings: If the full home study is waived, a basic screening fee usually ranges from $300 to $500.
  • Lawyer Fees: An uncontested relative adoption typically costs $2,000 to $4,000. However, if you must litigate a contested TPR trial, legal fees can easily exceed $10,000.
Uncontested (Parents Consent)$2,000 - $4,000
Contested TPR Trial$10,000+
Subsidized GuardianshipOften state-funded if via foster care

How Long Does the Process Take?

If the biological parents voluntarily sign their consents, a kinship adoption can be finalized in as little as 4 to 6 months. If a parent contests the termination of their rights, the required court hearings, depositions, and trials can drag the process out for 12 to 18 months or more.

Do we need to become licensed foster parents first?

No. If you are doing a private relative adoption directly through the family courts, you do not need to become state-licensed foster parents. However, if the child is already in state custody, getting licensed can provide you with financial stipends.

Can the biological parent pay child support after adoption?

No. Once an adoption is finalized, the biological parent's rights and responsibilities-including the duty to pay child support-are permanently severed.

Will the child's last name change?

Yes, if you choose. During the final adoption hearing, you can petition the judge to legally change the child's last name to match your family's name.

What if we do not know who the father is?

The court requires you to make a diligent effort to identify and locate the father. If he remains unknown, you will publish a legal notice in a local newspaper to terminate the rights of any 'John Doe' father.
