Can a stepparent adopt if the biological parent has a mental illness in South Dakota?

Yes, a stepparent can ask the South Dakota Circuit Court to approve an adoption when the child's other biological parent has a mental illness. A diagnosis alone is not listed as a bar to adoption. What matters is how the case fits the legal grounds, such as that parent's consent or abandonment.

Where the case is filed: Your adoption petition goes to the Circuit Court in your county under South Dakota Codified Laws Chapter 25-6. South Dakota has no minimum residency period, so you don't have to live in the state for a set time before filing.

Consent and mental illness: How a diagnosis, a guardianship, or a finding of incapacity affects the other parent's consent is a question for the Circuit Court clerk in your county or a South Dakota family law attorney. The same goes for whether a guardian must be notified or someone must be appointed to represent the parent. If you aren't sure the parent can understand and sign a consent, raise that with one of them before you file.

If the parent has been absent: South Dakota's abandonment provision, SDCL § 25-6-4(2), uses a period of 6 months. Whether a particular parent's absence meets that provision, particularly when illness is part of the story, depends on your family's facts. An attorney or the clerk can speak to your specific situation.

Other South Dakota points that apply:

• Child's consent: A child who is 12 or older must consent (SDCL § 25-6-5).
• Home study: It is waived for stepparent adoptions (SDCL § 25-6-10).
• Termination of rights: It is not a separate court proceeding.
• Timeline: A stepparent adoption in South Dakota runs about 3-6 months.
• Filing fee: The Circuit Court clerk in your county can confirm the current amount.

When to get individual legal help: If the other parent is likely to object, can't be located, or has a court-appointed guardian, the outcome may turn on details specific to your family. An attorney can advise you on that one issue, and you can still prepare the rest of your paperwork yourself.
