What is an abandonment affidavit for adoption in Kansas?

An abandonment affidavit in Kansas is a sworn, notarized written statement that lays out the facts about a biological parent's absence from a child's life. It is used in a stepparent adoption when that parent is not part of the process, and it is filed with the District Court in your county. The abandonment period in Kansas is 24 months under K.S.A. § 59-2136.

What it usually covers: The affidavit tells the story of the other parent's absence in plain, specific terms.

• The date of the last known contact between that parent and the child
• What has happened since then, such as visits, calls, letters or messages, or the lack of them
• How long the absence has lasted, measured against the 24-month period in K.S.A. § 59-2136
• Whether any support has been provided
• Any efforts you or your spouse made to keep the parent involved

Who signs it: The person with direct knowledge of the facts, usually your spouse as the child's parent, signs it in front of a notary. Because it is sworn, accuracy matters. Use real dates and concrete details, and be honest about anything that doesn't help your case. Vague or exaggerated statements only create problems. The District Court clerk in your county can tell you about any local form or formatting preferences.

Why it matters: The affidavit is where you put the facts on the record for the judge. Kansas has no fixed residency waiting period for filing (K.S.A. § 59-2126(c)), so the abandonment timeline is the key period to document carefully.

Where it fits in the process: The affidavit is one part of your filing, along with the petition and the other required forms. Court filing fees in Kansas typically run $150-$300, and a stepparent adoption commonly takes 3-6 months from start to finish. Total out-of-pocket cost for a family filing on their own is typically under $1,000, compared with $3,000-$5,000+ for an attorney.

When to get extra help: Some situations depend heavily on the specific facts. If the other parent is likely to object, if you're unsure of the parent's whereabouts, or if there has been any recent contact or support, ask the District Court clerk or a Kansas attorney how the law applies to your case. They can answer that specific question for you.
