Answer
Child support in Kansas ends when a child turns 18 years old under K.S.A. § 23-3001. Kansas law provides two exceptions that extend the obligation: support continues automatically through June 30 of the school year in which the child turns 18 if still enrolled in high school, and a court may extend support through age 19 if both parents participated in a decision that delayed high school completion. Filing a motion to terminate child support costs approximately $62 in Kansas district courts as of early 2026.

Kansas Child Support Termination Age: The 18-Year-Old Rule
Kansas child support terminates when a child reaches the age of 18 under K.S.A. § 23-3001(a). Kansas defines 18 as the age of majority, making it one of the straightforward states for determining when child support ends. Unlike states such as Missouri (which allows extensions to age 21 for college) or Indiana (which permits support to age 19 for high school students and age 21 for certain college attendance), Kansas keeps its default cutoff at 18. The termination is not automatic in all cases, however, because the court trustee in each county tracks school enrollment status before releasing the paying parent from the obligation.
The Kansas school year runs from July 1 through June 30. When a child turns 18 during the school year, the county court trustee mails a Certification of School Attendance Form to verify whether the child is still enrolled. If the child has already graduated or is not attending school, child support ends at the conclusion of that payment cycle following the 18th birthday. If there are multiple children on a single child support order, the obligation does not end entirely when one child emancipates. Instead, the total support amount decreases proportionally based on the remaining minor children, and any arrears owed at the time of emancipation remain enforceable as a judgment.
High School Extension: When Child Support Continues Past 18
Kansas child support automatically extends beyond age 18 when the child is still a bona fide high school student at the time of their 18th birthday, continuing through June 30 of that school year under K.S.A. § 23-3001(b). This extension requires no court motion and no additional filing fee. The Court Trustee handles verification through the school attendance certification process. For example, a child born in October 2008 who turns 18 in October 2026 while still enrolled as a high school senior would continue receiving support through June 30, 2027, when the school year concludes.
A second, more limited extension applies under K.S.A. § 23-3001(b)(3). If the child remains a bona fide high school student after June 30 of the year they turned 18, a court may order support to continue through the school year in which the child turns 19. This extension requires a court order and applies only when both parents jointly participated in, or knowingly acquiesced to, a decision that delayed the child's completion of high school. Examples include parents who held a child back a grade, allowed the child to transfer schools resulting in lost credits, or approved a gap year abroad. The requesting parent must file a motion and demonstrate the parental role in the delay. A bona fide high school student means a student enrolled full-time in an accredited Kansas high school, actively pursuing a diploma or GED equivalent.
Early Termination: Emancipation Before Age 18
Kansas child support can end before the child turns 18 through emancipation events recognized under Kansas law. Marriage terminates the child support obligation immediately because a married minor is legally emancipated. Active-duty military service also triggers emancipation regardless of age. A court decree of emancipation under K.S.A. § 38-108 and K.S.A. § 38-109 provides the third pathway, requiring the minor to be at least 14 years old, though courts generally expect the minor to demonstrate financial self-sufficiency.
The Kansas emancipation process requires a next friend (any person over age 21) to file the petition in the district court of the county where the minor has lived for at least 1 year. The court requires public notice published in a newspaper for 3 consecutive weeks. The hearing cannot occur until at least 30 days after the first publication. The court must find that the minor is of sound mind, capable of managing their own affairs, and that emancipation serves the minor's best interests. Once a court grants emancipation, the child support obligation terminates as of the date of the order.
Death of either the child or the paying parent also terminates the child support obligation. However, any arrears that accumulated before the date of death remain enforceable against the deceased parent's estate under Kansas law.
College and Post-Secondary Education: Kansas Does Not Require Support
Kansas courts cannot order parents to pay child support or college expenses after the child turns 18 and completes high school. K.S.A. § 23-3001 caps the mandatory obligation at age 18 (or 19 in the limited high school completion scenario described above). This places Kansas among the majority of states that do not mandate post-secondary education support, in contrast to states like Indiana (support to age 21 for college under certain conditions), Missouri (support to age 21 for higher education), and Iowa (post-secondary education subsidy available through age 22).
However, divorcing parents in Kansas frequently include voluntary provisions for college expenses in their separation agreements. Once a judge incorporates these contractual terms into a court order, they become enforceable. Common provisions include splitting tuition at a Kansas public university, covering room and board for a set number of semesters (typically 8), and specifying GPA requirements (commonly 2.0 or higher) for continued support. Parents negotiating a divorce settlement should consider including these provisions because Kansas courts will not impose college obligations retroactively.
Child Support for Disabled Adult Children in Kansas
Kansas does not require parents to continue child support for a disabled adult child past age 18, which distinguishes the state from jurisdictions like Missouri, Indiana, and Illinois that permit extended support for adult children with severe physical or mental disabilities. Under K.S.A. § 59-2006(a), Kansas parents have no statutory duty to support a child with disabilities beyond the age of majority. The only mechanism for extending support for a disabled child past 18 is a voluntary written agreement between both parents, approved by the court, under K.S.A. § 23-3001(b)(1).
Families with disabled children approaching age 18 should explore alternative support mechanisms. Kansas Medicaid provides services for adults with disabilities through the Home and Community Based Services (HCBS) waiver programs. Supplemental Security Income (SSI) may provide monthly payments of up to $943 per month in 2026 for qualifying individuals. Parents may also establish an ABLE (Achieving a Better Life Experience) account under the Kansas ABLE Savings Plan, allowing tax-advantaged savings of up to $18,000 per year (2026 limit) without jeopardizing means-tested benefits.
How to Modify or Terminate a Kansas Child Support Order
Filing a motion to modify or terminate child support in Kansas costs approximately $62 ($40 docket fee plus a $22 surcharge) as of early 2026, though some counties assess small additional surcharges (Johnson County adds $1.50; Sedgwick County adds $2.00). Verify fees with your local district court clerk before filing. A parent seeking termination must file a Motion to Terminate Child Support in the district court that issued the original order. Kansas allows fee waivers for parents who cannot afford filing costs through a Poverty Affidavit.
The modification process follows these steps:
- Obtain the required forms from the Kansas Judicial Council at kjc.ks.gov or the Kansas Self-Help Center at self-help.kscourts.gov
- Complete the Motion to Modify/Terminate Child Support, including the reason for termination (child turned 18, emancipation, marriage, or other qualifying event)
- File the motion with the district court clerk and pay the approximately $62 filing fee
- Serve the other parent with a copy of the motion following Kansas service of process rules
- Attend the hearing, where a judge will review the evidence and enter an order
Alternatively, the Kansas Department for Children and Families (DCF) Child Support Services can assist with modifications at no cost for cases where DCF is already involved in enforcement. Parents can request a review through dcf.ks.gov. DCF will review the existing order against current income and the Kansas Child Support Guidelines, and if a material change in circumstances exists (generally a 10% or greater change in the calculated amount), DCF will file the modification on the parent's behalf.
Child support does not terminate automatically on the child's 18th birthday in most Kansas counties. The paying parent must either wait for the Court Trustee to verify emancipation through the school attendance certification process or proactively file a motion to terminate. Continuing to pay without filing can create overpayment issues, while stopping payments without a court order can result in contempt charges and wage garnishment.
2024-2026 Kansas Child Support Guidelines Updates
Kansas enacted significant changes to child support calculations effective August 1, 2024, under Kansas Supreme Court Administrative Order 2024-RL-068. The updated Kansas Child Support Guidelines expanded income tables from $15,500 to $18,000 in monthly gross income and implemented across-the-board increases in support amounts, with families having 1 or 2 children seeing the largest percentage increases. The guidelines were restructured from 68 to 63 pages, reorganizing Section D into six separate sections (D through I) covering computation, parenting time adjustments, health insurance, work-related child care costs, proportionate obligations, and the basic child support obligation.
A further revision took effect May 1, 2025, under Administrative Order 2025-RL-037, clarifying the Direct Expense Formula used to calculate support when parents share roughly equal parenting time. The Kansas Supreme Court released the latest version under Administrative Order 2025-RL-121 on October 3, 2025, incorporating all prior corrections retroactive to July 1, 2025.
Kansas uses an income shares model under K.S.A. § 23-3002, meaning both parents' incomes are combined to determine the total child support obligation, which is then divided proportionally. The guidelines carry the force of a rebuttable presumption under K.S.A. § 23-3003, meaning a court must follow them unless a parent demonstrates that applying the guidelines would be unjust or inappropriate in a specific case. The Court Trustee in each county collects a 5% fee on the support amount, split equally between both parents at 2.5% each.
| Factor | Pre-August 2024 | Post-August 2024 |
|---|---|---|
| Maximum Income Table | $15,500/month | $18,000/month |
| Guidelines Length | 68 pages | 63 pages |
| Section D Structure | Single section | Six sections (D through I) |
| Direct Expense Formula | Original language | Clarified (May 2025) |
| Federal Update Cycle | Every 4 years (45 C.F.R. 302.56) | Every 4 years (45 C.F.R. 302.56) |
Kansas Residency and Jurisdiction Requirements
Kansas requires at least one spouse to be a bona fide resident of the state for a minimum of 60 days before filing for divorce under K.S.A. § 60-1603. For child custody and support jurisdiction, the child must have lived in Kansas for at least 6 consecutive months before filing, as required by the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA). Military personnel stationed in Kansas qualify as residents for filing purposes even if their home of record is another state.
Kansas imposes a 60-day waiting period between filing a divorce petition and finalizing the divorce, separate from the 60-day residency requirement. This means the absolute minimum timeline from establishing Kansas residency to obtaining a final divorce decree is approximately 120 days (60 days residency plus 60 days waiting period), though contested cases with child support disputes typically take 6 to 12 months.
Enforcement When a Parent Stops Paying
Kansas enforces child support obligations through multiple mechanisms when a paying parent fails to meet their court-ordered obligation. The Kansas DCF Child Support Services division can pursue income withholding (wage garnishment) under K.S.A. § 23-3005, intercepting up to 50% of disposable earnings for parents supporting another family and up to 60% for those without another family to support, with an additional 5% allowed if arrears exceed 12 weeks. Kansas can also intercept federal and state tax refunds, suspend driver's licenses and professional licenses, deny or revoke passports for arrears exceeding $2,500, and place liens on real and personal property.
Contempt of court is the most serious enforcement tool. A Kansas judge can impose a jail sentence of up to 6 months for willful failure to pay child support. The Kansas Crime Victims Compensation Board can also refer cases involving arrears exceeding $10,000 to the county attorney for criminal prosecution under K.S.A. § 21-5606, which classifies willful failure to pay support as a severity level 9 nonperson felony, carrying a potential prison sentence of 5 to 17 months.
Frequently Asked Questions
At what age does child support end in Kansas?
Child support in Kansas ends at age 18 under K.S.A. § 23-3001. If the child is still attending high school at 18, support continues automatically through June 30 of that school year. In rare cases where parents caused a delay in high school completion, a court may extend support through the school year in which the child turns 19. Kansas does not extend child support for college attendance.
Does child support automatically stop at 18 in Kansas?
Child support does not automatically stop on the child's 18th birthday in most Kansas counties. The County Court Trustee sends a Certification of School Attendance Form before the child turns 18 to verify enrollment status. If the child has graduated or is not enrolled, support terminates at the end of that payment cycle. Parents should not unilaterally stop payments without a court order or Court Trustee confirmation, as doing so can result in contempt of court charges.
Can Kansas courts order parents to pay for college?
Kansas courts cannot order parents to pay for college or any post-secondary education expenses. K.S.A. § 23-3001 limits mandatory child support to age 18 (or 19 in limited high school extension cases). However, parents can voluntarily agree to college support provisions in their divorce settlement, and once incorporated into a court order, those contractual obligations become enforceable.
How do I file to terminate child support in Kansas?
File a Motion to Terminate Child Support with the district court that issued the original order. The filing fee is approximately $62 as of early 2026 ($40 docket fee plus $22 surcharge). Forms are available at the Kansas Judicial Council website (kjc.ks.gov) or the Kansas Self-Help Center (self-help.kscourts.gov). After filing and serving the other parent, a judge will schedule a hearing to review the motion.
Does Kansas require child support for disabled adult children?
Kansas does not require parents to pay child support for disabled adult children past age 18. Under K.S.A. § 59-2006(a), there is no statutory duty to support a child with disabilities beyond the age of majority. Parents may voluntarily agree to extended support under K.S.A. § 23-3001(b)(1), and families should explore SSI benefits (up to $943/month in 2026) and Kansas HCBS Medicaid waivers as alternative support.
What happens to child support arrears when the child turns 18 in Kansas?
Child support arrears do not disappear when the child turns 18 or when the current support obligation ends. Back support owed at the time of emancipation becomes a judgment that remains enforceable under Kansas law. The custodial parent can pursue collection through wage garnishment, tax refund interception, property liens, and contempt of court proceedings until the full arrearage is paid.
Can a child be emancipated before 18 in Kansas to end child support?
Yes, Kansas allows minors age 14 and older to petition for emancipation under K.S.A. § 38-108. A next friend (someone over 21) must file the petition in district court after the minor has resided in the county for at least 1 year. The process requires 3 weeks of published notice and a hearing at least 30 days after first publication. Marriage and active-duty military service also trigger automatic emancipation before age 18.
How were the 2024 Kansas child support guidelines changed?
The August 2024 Kansas Child Support Guidelines (Administrative Order 2024-RL-068) expanded income tables from $15,500 to $18,000 monthly gross income and increased support amounts across all family sizes, with 1-child and 2-child families seeing the largest percentage increases. The guidelines were condensed from 68 to 63 pages, and Section D was split into six sections (D through I). Further revisions in May and October 2025 clarified the Direct Expense Formula.
What is the Court Trustee's role in Kansas child support?
The County Court Trustee in Kansas manages child support collection and disbursement under K.S.A. § 23-3004. The Trustee collects a 5% fee on the support amount (2.5% from each parent), processes payments, tracks school enrollment for emancipation verification, and enforces orders through wage garnishment. The Trustee also mails the Certification of School Attendance Form before a child turns 18 to determine whether support should continue.
Can I modify the child support amount before the obligation ends?
Yes, either parent can file a Motion to Modify Child Support under K.S.A. § 23-3007 when a material change in circumstances exists. Kansas generally considers a 10% or greater change in the calculated support amount as material. The filing fee is approximately $62. The Kansas DCF Child Support Services division can also initiate modifications at no cost for cases in the state enforcement system. Common grounds include job loss, significant income change, change in parenting time, or a child's changed needs.
