FORMULA How Kansas Calculates Child Support
Kansas Statutes Section 38-2346 and Kansas Supreme Court Administrative Order 128 govern child support. Kansas publishes a Child Support Schedule table updated periodically.
AGE When Does Child Support End in Kansas?
Child support in Kansas ends when the child turns 18 — Support ends at 18 or high school graduation. Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.
INTEREST Arrears Interest in Kansas
Kansas charges 4% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.
ENFORCEMENT Kansas Child Support Enforcement
Kansas has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.
MODIFY Modifying Child Support in Kansas
Child support can be modified in Kansas when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
