Can a stepparent adopt without the father's permission in South Dakota?

Yes, in some situations. In South Dakota, a stepparent may be able to adopt without the father's permission when the father has abandoned the child, and the abandonment period South Dakota uses is 6 months (SDCL § 25-6-4(2)). Whether your situation fits depends on your facts.

How the abandonment route works: The adoption is filed in the Circuit Court. South Dakota does not treat ending the father's rights as a separate case, so the question of his rights is handled as part of the adoption process. The Circuit Court judge decides whether the facts meet the legal standard.

What the 6 months means for you: The period is the starting point, not a guarantee. Exactly what the court counts as abandonment, and what proof it expects, is something to confirm with the Circuit Court clerk in your county or with an attorney. Gather what you have, such as dates of the last contact, messages, and any records of visits or support. Then ask about your specific situation.

Other South Dakota points that affect a stepparent adoption:

• Child's consent: South Dakota sets the child consent age at 12 (SDCL § 25-6-5). If your child is 12 or older, plan to talk with them about the adoption.
• Residency: South Dakota has no minimum residency period before you can file.
• Home study: It is waived for stepparent adoptions (SDCL § 25-6-10), so you do not have to go through that step.
• Timeline: Stepparent adoptions in South Dakota typically take 3-6 months.

When to get individual help: Some situations turn on the details of your family, and you should get guidance on those specifically.

• The father objects or contests the adoption. An attorney can explain how the court may view your case.
• You do not know where the father is. The Circuit Court clerk or an attorney can tell you what South Dakota expects for notifying him.
• You are unsure whether your facts meet the abandonment standard. An attorney can review your circumstances.

If the father is willing to sign, that is often the more straightforward path. If he is not, you still have options to explore.
