Kansas Custody Laws & Parenting Plans

Kansas child custody law centers on one principle: the best interests of the child. Under K.S.A. 23-3203, courts evaluate a nonexclusive list of factors when deciding legal custody, residency, and parenting time. Whether you're filing for divorce through an uncontested or contested process, understanding how Kansas structures custody decisions is the first step toward building a parenting plan that works for your family.

This guide explains the types of custody recognized in Kansas, the statutory best-interest factors courts weigh, parenting plan requirements, the income-shares child support model, and the modification standards that apply after a decree is entered.

Types of Custody in Kansas

Kansas law distinguishes between legal custody and residency (physical custody). Legal custody grants the authority to make major decisions about a child's health, education, and welfare. Residency determines where the child lives on a day-to-day basis. These two concepts can be awarded independently under K.S.A. 23-3206.

Joint Legal Custody

When parents share joint legal custody, both have equal decision-making authority over major life decisions including:

• Medical, dental, and surgical treatment
• Educational choices (school selection, special services)
• Religious upbringing
• Extracurricular activities

Joint legal custody does not require equal parenting time. One parent may have primary residency while both retain decision-making rights. Kansas courts do not apply a statutory presumption favoring joint custody, but the arrangement is common when both parents are fit and willing to cooperate.

Sole Legal Custody

A court may award sole legal custody to one parent when joint custody would not serve the child's best interests. Common reasons include domestic violence, substance abuse, a parent's inability to cooperate on decisions, or a history of neglect. The non-custodial parent retains the right to parenting time unless the court finds that contact would endanger the child.

Residency (Physical Custody)

Residency determines the child's primary home. Kansas courts may designate one parent as the residential custodian or establish a shared residency schedule. The parenting plan must specify the residential arrangement and a detailed schedule for each parent's time with the child.

Best Interest of the Child Factors

Under K.S.A. 23-3203, the court considers a nonexclusive list of factors to determine custody, residency, and parenting time. No single factor is dispositive, and the court may weigh additional considerations relevant to the child's welfare:

1. Parental roles: The responsibilities each parent has assumed in raising the child before and after separation
2. Child's needs: The physical, emotional, educational, and developmental needs of the child
3. Parent-child relationships: The strength and quality of the bond between the child and each parent
4. Adjustment: The child's ties to home, school, siblings, extended family, and community
5. Willingness to foster the other parent's relationship: Each parent's ability and willingness to support the child's ongoing relationship with the other parent
6. Domestic abuse history: Evidence of spousal abuse, child abuse, or neglect by either party
7. Parental fitness: Each parent's physical and mental health, work schedule, and ability to provide stable care
8. Geographic proximity: The distance between the parents' residences and its impact on the child's ability to spend time with each parent
9. Child's preference: The wishes of a child of sufficient age and maturity (Kansas does not set a specific age threshold)

Kansas courts give significant weight to the willingness to foster factor. A parent who interferes with the other parent's relationship or attempts to alienate the child may face an unfavorable custody outcome.

Parenting Plan Requirements

Kansas law requires a parenting plan in every case involving minor children. Under K.S.A. 23-3212, the plan must address at minimum:

• Legal custody designation: Which parent (or both) makes major decisions about the child
• Parenting time schedule: A detailed calendar appropriate to the child's age covering regular weeks, weekends, holidays, school breaks, and summer
• Dispute resolution method: How parents will resolve disagreements about parenting time (mediation, arbitration, or return to court)

Most Kansas courts also expect the plan to address:

• Exchange procedures (times, locations, transportation responsibilities)
• Communication norms (phone calls, video contact, email)
• Information sharing (school records, medical updates, extracurricular schedules)
• Relocation notice procedures (K.S.A. 23-3222 requires 30 days' written notice before a move)
• Special provisions for military deployment, extended travel, or other circumstances

If parents agree on a plan, the court presumes the agreement serves the child's best interests under K.S.A. 23-3202. The court may reject the agreement only by making specific findings explaining why it does not serve the child's welfare.

Mediation and Parent Education

Kansas courts encourage and often require alternative dispute resolution before custody issues reach trial:

Mandatory Mediation

Under Kansas Supreme Court Rule 907, most judicial districts require mediation before a contested custody hearing. The court appoints an approved mediator, and discussions are confidential. If the parents reach agreement in mediation, the terms are incorporated into the parenting plan. Courts may waive mediation when domestic violence or safety concerns make it inappropriate.

Parent Education Programs

K.S.A. 23-3214 requires courts to inform parents about the impact of divorce on children. Many Kansas judicial districts have implemented mandatory parent education courses that must be completed before the court finalizes custody orders. Programs typically cost $50 to $75 per parent and cover co-parenting strategies, child development, and conflict reduction techniques. The Kansas Judicial Branch parenting planning page provides additional resources.

Relocation Rules Under K.S.A. 23-3222

Kansas imposes strict notice requirements when a parent with custody or parenting time wants to move. Under K.S.A. 23-3222:

• 30-day written notice must be sent by restricted mail (return receipt requested) before changing the child's residence or removing the child from Kansas for more than 90 days
• The non-moving parent may file a motion to modify custody based on the proposed relocation
• The court evaluates the move against the best interests of the child, the effect on the other parent's rights, and the increased cost the move imposes on the non-moving parent's ability to exercise parenting time

Failing to provide proper notice can result in contempt of court and may weigh against the moving parent in any subsequent custody modification proceeding.

How Custody Affects Child Support in Kansas

Kansas uses an income shares model for child support. Both parents' incomes are combined, and each parent bears a proportional share of the child's basic support obligation. The parenting time schedule directly affects the calculation:

• Under 35% parenting time: Standard calculation applies
• 35–39% parenting time: 10% reduction to the obligor's share
• 40–44% parenting time: 20% reduction
• 45–49% parenting time: 30% reduction
• 50% or near-equal time: Kansas applies a Direct Expense Formula where one parent pays direct child expenses and the other makes a balancing transfer

The current Kansas Child Support Guidelines (Administrative Order 2025-RL-037, effective May 1, 2025) set a combined income cap of $18,000 per month. For income above the cap, courts have discretion to extrapolate. For a detailed breakdown, see our Kansas child support calculations guide.

Modifying Custody and Parenting Time

Kansas allows modification of custody and parenting time when circumstances change and modification serves the child's best interests. Under K.S.A. 23-3218 and K.S.A. 23-3219:

Custody Modification

Either parent may petition to modify legal custody or residency at any time by demonstrating that the modification is in the child's best interests. Courts may require renewed mediation or case management before scheduling a contested hearing. The petitioner must specify the factual allegations supporting the requested change.

Child Support Modification

Under K.S.A. 23-3005, child support modification follows a tiered system:

• Within 36 months of the last order: The requesting parent must show a material change in circumstances. A 10% or greater change in the presumptive guideline amount generally establishes materiality.
• After 36 months: Either parent may seek modification without showing material change. The court recalculates support using current incomes and the latest guidelines.
• Retroactivity: Modifications are retroactive only to the first day of the month after the motion is filed. Delayed filings lose retroactive relief.

Temporary Orders During Divorce

Under K.S.A. 23-2707, the court may issue temporary orders governing custody, parenting time, and support while the divorce is pending. These orders establish stability during litigation and typically include:

• Temporary legal custody designation
• A proposed parenting time schedule
• Temporary child support calculated under the current guidelines
• Payment routed through the Kansas Payment Center (KPC)

The 60-day waiting period under K.S.A. 23-2708 means that no divorce can be finalized sooner than 60 days after the petition is filed. For a complete overview of the Kansas divorce process, see our Kansas divorce timeline.

Interstate Custody and the UCCJEA

Kansas adopted the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) under K.S.A. 23-37,101 through 23-37,405. When filing, parties must disclose:

• Any prior or pending custody proceedings in other states
• A five-year address history for the child
• The names and addresses of anyone with whom the child has lived

This information helps the court determine whether Kansas has jurisdiction. Confidentiality protections are available when disclosure would pose a safety risk.
