What We Help Wisconsin Families Accomplish
What is Stepparent Adoption?
Stepparent adoption is the legal process by which a stepparent becomes the legal parent of their spouse's child in Wisconsin. This permanently establishes parental rights including inheritance, medical decision-making, and the full parent-child relationship under Wisconsin Statutes Chapter 48. If the other biological parent is absent or won't cooperate, the adoption can still proceed—over 80% of adoptions we help with are completed without the other parent's consent.
Timeline: Typically 3-6 months from filing to finalization in Wisconsin Circuit Court
What is Adult Adoption?
Adult adoption in Wisconsin is the legal process of adopting someone who is 18 years or older. It's commonly used by stepparents to formally adopt adult stepchildren, creating legal inheritance rights and official family recognition. Adult adoption in Wisconsin is simpler than minor adoption—typically not requiring home studies or biological parent consent, only the adult adoptee's written consent.
Timeline: Much faster than minor adoption—typically just 4-8 weeks in Wisconsin
Who Can Adopt in Wisconsin?
Under Wisconsin adoption law, any adult living and working in Wisconsin may petition for adoption if it is in the best interest of the adoptee. For stepparent adoption specifically, you must be:
- Legally married to the child's biological parent
- A Wisconsin resident for at least 6 months
- Able to provide for the child's welfare
- Pass required background checks
Since 2001, StepParent Adoption 360 has helped over 385 Wisconsin families complete their adoptions — saving an average of $4,600 compared to hiring an attorney.

Adult Adoption in Wisconsin
A simpler, faster path to making your family official
Adult adoptions in Wisconsin are usually simpler and faster than adopting a minor. If your stepchild is 18 or older and you want to formalize your parent-child relationship, adult adoption creates full legal recognition including inheritance rights.
Why Adult Adoption is Simpler:
No Termination
Typically no need to terminate another parent's rights
Adult Consent Only
The adult adoptee simply provides written consent
Simplified Process
No home study, no background check—typically completed in just 4-8 weeks
The Process: Submit a Petition for Adult Adoption to your county's Circuit Court, attend a brief hearing, and receive the Final Judgment of Adoption. You can then request a revised birth certificate for the adoptee if desired.
