Can a step-grandparent adopt a grandchild in Kansas?

Yes, Kansas law allows an adult, or a married adult couple together, to adopt a minor or an adult as their child, but a step-grandparent adoption is not the same as a stepparent adoption, so the details depend on your family's facts. Kansas Statutes Annotated Chapter 59, Article 21 says "any adult, or married adult couple jointly, may adopt any minor or adult as their child" (K.S.A. 59-2113). No numeric minimum age is stated beyond being an adult.

Why it differs from stepparent adoption: A stepparent adoption is for someone married to the child's parent. A step-grandparent is married to the child's grandparent, so shortcuts built for stepparents may not apply to you. Whose consent is needed, and whether a parent's rights must be addressed, turns on your facts. That is especially true if a parent is absent, unknown, or might object. Please confirm those points with the District Court clerk in your county or with a Kansas adoption attorney.

If your grandchild is a minor, these Kansas points are relevant:

• Court: The petition goes to the District Court. Kansas has 105 counties.
• Residency: Kansas sets no minimum residency period (K.S.A. § 59-2126(c)).
• Child's consent: A child who is 14 or older must consent (K.S.A. § 59-2129).
• Abandonment: The abandonment period is 24 months (K.S.A. § 59-2136). Whether it has any role in your case depends on the facts.
• Home study: Kansas waives it in stepparent adoptions (K.S.A. § 59-2132). Ask the clerk how a step-grandparent case is handled.
• Cost and timeline: Stepparent adoptions in Kansas typically take 3-6 months. Court filing fees run $150-$300, and the total is typically under $1,000. Ask the clerk whether your case would look different.

If your grandchild is an adult (18 or older): Kansas places no relationship, disability, or age-gap condition on adult adoption, so being a step-grandparent is not a barrier. The petition must state the facts showing the reasons for the adoption.

• Consents: The adult being adopted must consent, and so must your spouse. The adoptee's parents do not consent, though the court may order notice to them.
• Home study: Not required for an adult adoption (K.S.A. 59-2137).
• Residency and venue: Jurisdiction exists if you or the adult grandchild lives in Kansas. Venue is the county where either of you lives.
• Hearing: A hearing is required before the District Court.
• Timeline: Adult adoptions typically take 4-8 weeks.
