How to Process a Stepparent Adoption in Kentucky When the Biological Father Abandons the Child

Current as of: September 28, 2026 Adoption Law Kentucky
👨‍👩‍👧‍👦
In Kentucky, you can adopt your stepchild without the biological father's consent if you prove he abandoned the child for at least 90 days or failed to pay support for six months. Court filing fees are typically around $150 to $175.

When a stepparent steps up to raise a child, they often take on the financial and emotional responsibilities that an absent biological father left behind. If you are ready to make your parent-child relationship official, the biggest hurdle is usually dealing with an absentee biological parent who refuses to sign a consent form-or who simply cannot be found. Kentucky law provides a clear path to adopt your stepchild without their consent through the involuntary termination of parental rights (TPR). Whether you are filing in Owensboro, Richmond, or Louisville, the courts require strict proof of abandonment. Because terminating parental rights is one of the most serious actions a court can take, we strongly advise you to hire a skilled Kentucky family lawyer from our catalog to handle your case.

Step-by-Step Process in Kentucky

Adopting a child without the biological father's consent combines two legal actions: terminating his rights and granting your adoption. This process is governed by KRS Β§ 199.502.

Step 1: Gathering Evidence of Abandonment

Before filing, you must compile evidence that the biological father has abandoned his duties. Collect text messages, emails, child support payment histories, and witness testimonies proving he has not visited or financially supported the child for the required statutory period.

Step 2: Filing the Adoption Petition

Your attorney will file a Petition for Adoption in your local court, such as the Warren County Family Court, Bowling Green or the Daviess County Family Court, Owensboro. The petition must explicitly allege the legal grounds for why the biological father's consent is not required under Kentucky law.

Step 3: Serving the Biological Father

You must formally serve the biological father with the lawsuit, giving him a chance to respond. If he lives in Kentucky, this is usually done via a sheriff's deputy or certified mail. If he ignores the summons, the court can proceed by default.

Step 4: The Evidentiary Hearing

If the father contests the adoption, or even if he does not show up, the judge will hold an evidentiary hearing. Your lawyer will present your evidence of abandonment. The precedent set in R.M. v. R.B., 281 S.W.3d 293 (KY Court of Appeals 2009) highlights that the court will strictly evaluate whether the statutory grounds for abandonment have been met by clear and convincing evidence before terminating rights.

Proving 90-Day Abandonment in Kentucky

Under KRS Β§ 199.502(1), a Kentucky judge can grant a stepparent adoption without the biological parent's consent under specific conditions. The two most common grounds for a stepparent to use are:

  • 90-Day Abandonment: The parent has abandoned the child for a period of not less than ninety (90) days. This means absolutely no contact, no phone calls, and no visits.
  • Six-Month Failure to Support: The parent has continuously or repeatedly failed or refused to provide essential parental care and protection for the child for a period of not less than six (6) months, and there is no reasonable expectation of improvement.

If the father occasionally sends a $20 birthday gift but pays no regular child support and rarely visits, an experienced attorney can argue that he has failed to provide essential care for six months, allowing the adoption to move forward.

Filing for TPR Without a Known Address for the Father

A common problem in stepparent adoptions is that the biological father has been gone so long that no one knows where he lives. You cannot simply tell the judge you don't know his address; you must make a diligent effort to find him. If he cannot be found, your attorney will file a Form AOC-110, Kentucky, Administrative Office of the Courts, Appointment of Warning Order Attorney. The court will then appoint a 'Warning Order Attorney'-a local lawyer whose sole job is to try and locate the absent father by searching public records and sending letters to his last known addresses. If the Warning Order Attorney cannot find him after 50 days, they file a report with the court, and the judge can legally proceed with terminating his rights without his physical presence.

How Much Does it Cost in Kentucky?

Filing an adoption without consent involves additional legal mechanisms that increase the overall cost.

Expense CategoryEstimated Cost in Kentucky
Court Filing Fees$150 - $175
Warning Order Attorney Fee$150 - $300
Guardian ad Litem (GAL) Fee$500 - $1,500
Lawyer Retainer (Contested)$3,500 - $7,500+

How Long Does the Process Take?

Terminating a parent's rights involuntarily takes time. If you have to use a Warning Order Attorney to search for the father, expect a mandatory 50-day delay. Overall, a stepparent adoption based on abandonment can take anywhere from 6 to 12 months to reach a final judgment in a busy court like the Jefferson County Family Court, Louisville.

Frequently Asked Questions (FAQ)

What if the biological father is in prison?

Incarceration alone does not automatically terminate parental rights. However, if his prison sentence prevents him from providing care for the child for a prolonged period, the court can factor his incarceration into the decision to grant the adoption without his consent.

Will terminating his rights erase his back child support debt?

Typically, terminating parental rights stops any future child support obligations. However, the biological father is still legally responsible for paying any past-due child support (arrears) that accumulated before the adoption was finalized, unless you agree to waive it.

Does the state appoint a lawyer for the child?

Yes. In cases where you are terminating a biological parent's rights involuntarily, the judge will often appoint a Guardian ad Litem (GAL) to represent the best interests of the child during the court proceedings.

What if the father shows up at the last minute to object?

If he appears in court and formally objects, the judge will hold a full trial. Your attorney will need to present overwhelming evidence of his abandonment and failure to support the child to convince the judge to terminate his rights anyway.
