If you and your child’s other parent were never married, you may be wondering how custody, parenting time, and child support are handled under Kansas law. Many parents assume that being listed on a birth certificate automatically creates custody rights, but that is not always the case.
For unmarried parents, establishing legal parentage is often the first step toward securing parenting rights and responsibilities. Whether you are a mother seeking child support or a father pursuing parenting time, understanding Kansas custody laws can help protect your relationship with your child.
At The Bright Family Law Center, our Kansas family law attorneys help parents establish paternity, create parenting plans, and resolve custody disputes with their children’s best interests in mind.
Determining Child Custody for Unmarried Parents in Kansas
The Kansas court does not make custody distinctions based on the marital status of the parents. Kansas Family Court’s principal concerns are what is in the best interests of the child, the bond between child and parent, each parent’s capacity to meet the child’s needs, and the child’s adjustment to their home, school, and community. For unmarried parents, it’s imperative to establish paternity before claiming custody rights.
Unmarried Custody Laws In Kansas
Whenever children are born to unmarried mothers, they are granted sole custodianship under Kansas Law. However, an unmarried father must establish paternity as the first step in making court orders for child support and parenting time arrangements. Kansas courts believe that the parent-child relationship with both mother and father is beneficial to the child’s welfare.
Unmarried Parents’ Rights
Unmarried parents in Kansas are expected to provide the following to their child:
- Financial support
- Healthcare
- Education
- Emotional well-being
- Upbringing and childcare
- Stable and loving environment

Does Kansas Favor Mothers in Unmarried Custody Cases?
Kansas courts do not automatically favor mothers or fathers when determining custody. Once legal parentage has been established, both parents generally have equal standing before the court. Judges focus on what arrangement serves the child’s best interests, including:
- The child’s physical and emotional needs
- Each parent’s ability to provide care
- The relationship between the child and each parent
- The child’s adjustment to home, school, and community
- Each parent’s willingness to support the child’s relationship with the other parent
While an unmarried mother initially has sole legal custody before paternity is established, courts do not presume that one parent is inherently better suited for long-term custody.
Can an Unmarried Father Get Custody in Kansas?
Yes. Once paternity is established, an unmarried father may seek:
- Joint legal custody
- Shared parenting time
- Primary residential custody
- Child support when appropriate
Kansas courts recognize the importance of maintaining meaningful relationships between children and both parents whenever possible.
Paternity Actions in Establishing Custody Rights
Paternity actions are legal steps or a court determination taken to establish the biological and legal father of a child. In Kansas, this can be initiated by all parties involved. Determining paternity is paramount for gaining custody and visitation rights for unmarried fathers. Clearing up paternity matters affirms a father’s rights, and gives access to family medical history, child support rights and obligations, and the comprehensive guidance that comes with knowing both parents.
Kansas’s custody laws offer proper guidance on establishing paternity for unmarried parents in Kansas when the following apply:
- A child is born to unmarried parents and the mother is seeking child support
- A child is born to unmarried parents and the state is seeking past due or current child support or reimbursement for medical bills
- A child is born to unmarried parents and the father is seeking to prove he’s the biological father to establish parenting rights
Kansas law legally obligates the care, shelter, and support of a child to its legal parents. For an unmarried mother, establishing paternity is necessary to order the other parent to participate in raising the child. Paternity may be established voluntarily or involuntarily. If you need assistance, sit down with a Kansas family law attorney because they serve clients and can answer questions in a custody consultation.
Voluntary and Involuntary Paternity in Kansas
The Kansas Parentage Act governs establishing paternity to determine a child’s legal parents in Kansas. Paternity may be voluntary if both parents agree on the biological father. This requires both parents to sign and file a “Voluntary Acknowledgement of Paternity (VAP)” form when the baby is born. Once this is completed, the name of the biological father will be added to the child’s birth certificate.
Involuntary paternity establishes paternity through the judicial process and may be “forced,” through a court order. The court may order genetic testing to confirm paternity in disputed cases. When paternity is unknown or denied, the court will order genetic testing. Typically, the first step for unmarried parents is to file a case under the Uniform Parentage Act.
The Importance of Establishing Paternity
There are many benefits to paternity determination, including:
- Establishing relationships with both parents
- Access to family history and information
- Access to medical insurance
- Opportunities to learn medical history and health risks
- Establishing rights to inherit the father’s estate
- Ability to sue on behalf of the father in cases of wrongful death and more
- The mother can share parental responsibilities and custody with the father
- The father can establish a relationship with the child, participate in the child’s life, request custody or parenting time, and show how much they care for their child.
Once paternity is established, the parent-and-child relationship extends equally to every child and every parent. The legal obligations on the child’s behalf are extended to the other parent as well.
What About Child Support and Custody?
Unmarried fathers have zero enforceable custody rights until they’ve established paternity. Once a successful paternity suit is made, a judge can decide on a custody schedule, whether joint custody is allowed, who has to pay child support, and how much that amount will be. They do this by considering factors such as your financial commitments and the child’s requirements. Legally, a portion of both parents’ income must be set aside for each child born.
Kansas child support obligations are calculated using the following:
- Both parents’ incomes
- The needs of the child
- The time each parent spends with the child.
Custody arrangements can also influence tax benefits, including exemptions, child tax credits, and dependent care credits, which can be significant during tax season. If you’re the other parent and want access to the benefits of supporting your child, speak with a legal professional.
Creating a Parenting Plan
A thorough parenting plan helps unmarried parents in Kansas share custody. The parenting plans detail daily routines, living arrangements, decision-making responsibilities, and how disputes will be resolved by considering the child’s age, needs, and the geographical location of each parent to minimize disruption in the child’s life.
If you are involved in a custody dispute or need help establishing parental rights, working with an experienced child custody attorney can help you protect your relationship with your child and pursue a parenting arrangement that serves your family’s best interests.
