In South Dakota, you are generally in a good position to adopt your stepchild if you are an adult married to the child's parent, and the child's other legal parent consents or the court finds the other parent has abandoned the child. Here is how the main points work.
Who can adopt: South Dakota law says any minor child may be adopted by any adult person (SDCL 25-6-2). The adopter must be at least 10 years older than the child unless the court finds that adoption by that adult is in the child's best interest (SDCL 25-6-2). Because you are an adult stepparent, your age is the starting point, and the court looks at the age gap too.
Residency: South Dakota has no minimum residency period for you before you can file. Older checklists that mention a set number of months of residence are not accurate.
Spouse's consent: SDCL 25-6-3 requires a married person to have the spouse's consent to adopt a child, unless the couple is lawfully separated or the spouse cannot consent. In a stepparent adoption, that spouse is usually the child's parent.
Consent of the other parent: In most cases, the other biological parent either signs consent or has abandoned the child. South Dakota uses a six-month abandonment period (SDCL § 25-6-4(2)). If the other parent is deceased, cannot be found, or will contest the adoption, the details depend on your facts. Ask the Circuit Court clerk in your county or an attorney about that specific situation.
Your child's consent: A child who is 12 or older has to consent to the adoption (SDCL § 25-6-5). For a younger child, there is no child-consent requirement.
Home study: A home study is waived in South Dakota (SDCL § 25-6-10), so you do not have to plan for one.
Court and timeline: Your adoption is filed in the Circuit Court in your county. South Dakota has 66 counties, including Sioux Falls, Rapid City, Aberdeen, Brookings and Watertown. A stepparent adoption typically takes 3-6 months. The clerk can tell you about filing fees, which vary, and any local procedures. Your amended birth certificate is handled through South Dakota Vital Records after the court finalizes the adoption.
If your stepchild is an adult: An adult may adopt another adult (SDCL 25-6-18). The adoptee must have lived in the adopter's home for at least 6 months while under age 21, and this must appear in the petition. That requirement is waived if the adoptee is the adopter's biological child. The petition must also include a written agreement that the adoptee will be treated in all respects as the petitioner's natural child, and the adoptee must give written consent. These adoptions typically take 4-8 weeks. Whether the spouse-consent rule in SDCL 25-6-3 applies to adult adoptions is not spelled out, so confirm that with the cl
