How do I adopt my stepchild if the biological mother won't sign in Wisconsin?

In Wisconsin, if the biological mother won't sign, you can ask the Circuit Court to move forward without her signature by showing grounds such as abandonment under Wis. Stat. § 48.415, and that request is handled within your adoption case. Termination of her rights is not a separate court case in Wisconsin.

Abandonment and the 6-month period. Wisconsin sets an abandonment period of 6 months under Wis. Stat. § 48.415. If the mother has been absent from your stepchild's life, the length of that absence matters. What counts as abandonment on your specific facts, such as occasional calls, texts, or support payments, is for the judge to decide. For that question, ask the Circuit Court clerk in your county or an attorney.

If she is in the child's life but still refuses. This is a harder situation, and the outcome depends on the facts. If she actively opposes the adoption, the court may need to hold a hearing and decide. An attorney can advise you on a contested case like this. A document service cannot predict how a judge will rule.

What else Wisconsin requires:

• Court: Your case is filed in the Circuit Court. Wisconsin has 72 counties, and you file in the county where your family's case belongs. The clerk can confirm local filing steps and the current filing fee.
• Residency: Wis. Stat. § 48.82 sets no minimum residency period. The adopting stepparent must be a Wisconsin resident, and the spouse who is the child's parent is part of that picture.
• Child's consent: Wisconsin does not require your stepchild's consent. A child 14 or older attends the hearing unless the court orders otherwise.
• Home study: It is waived for stepparent adoptions under Wis. Stat. § 48.88.
• Timeline: Stepparent adoptions in Wisconsin typically take 3-6 months. A case where the mother contests could take longer, and the clerk or an attorney can tell you more about what to expect.

Practical steps if she won't sign:

• Write down the last time she had contact with your stepchild and what that contact was.
• Gather any records that show her involvement or absence, such as messages, school or medical records, and support history.
• Ask the Circuit Court clerk in your county how they handle an adoption where one parent has not consented.
• If she says she will fight the adoption, talk to a family law attorney about that issue before you file.

You are not alone in this. Many stepparents face a parent who will not cooperate, and the law has a path for these situations. The key is to put the facts clearly in front of the court.
