How do I adopt my stepchild if the biological mother won't sign in Kansas?

In Kansas, you can still file a stepparent adoption in your county's District Court when the biological mother won't sign, and the main legal question is whether her rights can be ended, most often by abandonment under K.S.A. § 59-2136. Whether that applies depends on the facts of your family's situation.

If she has been absent: Kansas sets an abandonment period of 24 months in K.S.A. § 59-2136. If she has been out of the child's life for that long, abandonment may be the basis for your petition. How the court weighs particular facts, such as occasional calls, cards or payments, is something the District Court clerk or an attorney should confirm for your situation.

If she is involved but refuses: This is more complicated. The outcome depends on the details of her relationship with the child, so talk with an attorney about that specific issue before you file. The court clerk in your county can answer procedural questions, but not legal strategy.

What the process looks like:

• Filing: You file a Petition for Adoption in the District Court, along with a background information form and your spouse's consent to the adoption. Your spouse is the child's parent, so their consent is part of the packet.
• Notice to the mother: She needs to be formally told about the case. Kansas allows personal service by a sheriff or process server, or service by publication if you truly don't know where she is.
• Termination: In Kansas, ending her rights can be handled within the adoption case itself rather than as a separate lawsuit.
• Waiting and the hearing: Stepparent adoptions in Kansas typically take 3-6 months.

Other Kansas points that help:

• Residency: There is no minimum residency period under K.S.A. § 59-2126(c).
• Home study: It is waived for stepparent adoptions under K.S.A. § 59-2132.
• Your child's consent: If your child is 14 or older, their consent is required under K.S.A. § 59-2129.
• Spouse's consent: Kansas allows it to be signed any time after the child's birth.

Cost: Court filing fees run about $150-$300, and the total typically comes to under $1,000. Attorney-handled adoptions commonly run $3,000-$5,000+. If the mother contests, legal help may be worth the added expense, and an attorney can tell you what to expect.
