Yes. If you are married to your stepchild's parent and you live in Wisconsin, you can pursue a stepparent adoption of a newborn or infant through the Circuit Court in your county. Wisconsin's adoption law (Wisconsin Statutes Chapter 48) lets a spouse adopt when the other spouse is the child's parent (Wis. Stat. § 48.82).

Who can file:

  • You must be a Wisconsin resident and married to the child's parent (Wis. Stat. § 48.82).
  • Wisconsin sets no minimum length of residency, so you do not have to wait months before filing.
  • The case is filed in the Circuit Court. Wisconsin has 72 counties, and each clerk's office can tell you its local filing steps and fees.

The other parent:

For a newborn, the biggest question is usually the other legal parent. If that parent is involved, the usual route is for them to agree to the adoption. If they are not involved, Wisconsin law on abandonment is in Wis. Stat. § 48.415, which uses a 6-month period. Whether that period, or any other ground, applies to your baby depends on your family's facts. If the other parent is unknown, unwilling to agree, or contesting the adoption, talk to the Circuit Court clerk in your county or an attorney about your specific situation. Wisconsin does not treat this as a separate termination case in the stepparent process.

Wisconsin does not require the child's consent. A child 14 or older attends the hearing unless the court orders otherwise. That won't matter for an infant, but it explains why your baby's adoption is simpler in this respect than an older child's.

Home study:

Wisconsin waives the home study for stepparent adoptions (Wis. Stat. § 48.88). That removes a step that can add time in other types of adoption.

Timeline:

Stepparent adoptions in Wisconsin typically take about 3-6 months. The exact timing depends on your county's court calendar and on whether the other parent's rights are settled. The clerk can tell you the current filing fee.

Why families adopt early:

  • Your child is legally yours from infancy, which can matter for medical decisions and insurance.
  • Your child grows up with a clear legal relationship to you.
  • After the adoption is final, you can ask the Wisconsin Vital Records Office how to update the birth record. The clerk or vital records can confirm the steps and any fees.

Things to check before you start:

  • Whether the other parent will sign, or whether you need to address their rights another way.
  • Whether you and your spouse are
