Kansas Child Custody: A Parent's Guide

In short: Kansas decides legal custody, residency, and parenting time together under the best-interest standard, with joint legal custody generally expected absent specific reasons otherwise. Changing the child's residence, or removing the child from Kansas for more than 90 days, requires 30 days' written notice by restricted mail, and skipping that notice is punishable as contempt.

What Kansas generally provides

Under K.S.A. 23-3201, Kansas courts determine legal custody, residency, and parenting time together, all in accordance with the best interests of the child. An agreed parenting plan submitted by both parents is presumed to serve the child's best interest.

Important terminology

• Legal custody: decision-making authority over the child's upbringing; joint legal custody is generally expected absent a specific reason otherwise.
• Residency: where the child primarily lives, decided separately from legal custody.
• Parenting time: Kansas's term for the actual visitation/residential schedule.

How custody works in Kansas

Legal custody, residency, and parenting time as separate pieces

Unlike states that use a single "custody" determination, Kansas explicitly separates decision-making authority (legal custody) from where the child lives (residency) and the actual schedule (parenting time), all governed by the same best-interest standard but potentially structured differently case by case.

The best-interest factors

Courts weigh each parent's role and involvement with the child before and after separation, the desires of the child's parents as to custody or residency, and the desires of a child old enough and mature enough to express one, among the fuller list of factors in K.S.A. 23-3203. Where the court declines joint legal custody, it must state specific reasons.

Parenting schedules

Once legal custody, residency, and parenting time are set, families commonly build the actual schedule around patterns like 2-2-3 or week on, week off. See what is a parenting plan for what a strong plan generally covers, how to choose a custody schedule for a general framework, and the custody schedule generator to build the actual calendar.

Moving with your child (relocation)

Under K.S.A. 23-3222, a parent entitled to legal custody, residency, or parenting time must give the other parent written notice, sent by restricted mail with return receipt requested, at least 30 days before either changing the child's residence or removing the child from Kansas for a period exceeding 90 days. The notice must state the intended moving date and destination. Failing to give the required notice is indirect civil contempt, and the court may assess attorney fees and other expenses the other parent incurred. Notice generally isn't required where the other parent has been convicted of certain crimes against the child. Courts deciding whether to permit a relocation weigh the effect on the child's best interest, the effect on the other parent's parenting time, and the increased costs the move imposes on the parent exercising parenting time. See moving to another state with shared custody for how relocation standards tend to work more broadly across states.

Common questions

How is child support calculated? Kansas uses the income shares model under guidelines adopted by the Kansas Supreme Court and updated effective July 1, 2025: both parents' incomes are combined and run through the mandatory Child Support Worksheet, with each parent's proportionate share of combined income determining their obligation.

Can a custody order be changed later? Yes, generally on a showing of a material change in circumstances and that a modification serves the child's best interest.

What if my co-parent won't follow the custody order? You can file a motion for contempt with the court. Courts can order makeup parenting time and, in serious or repeated cases, hold a parent in contempt.

Practical considerations

Because Kansas's 30-day, restricted-mail notice requirement is specific and strictly enforced through contempt, don't rely on an informal text or phone call to satisfy it, use the proper method and keep proof of delivery. Whatever the order specifies, the operational part that follows it, keeping both households aligned on the same schedule, logging change requests instead of relying on memory, and keeping a record if an enforcement issue arises, is a separate, ongoing piece worth planning for.
