How do I request a modification in Kansas?

Within three years of the most recent order, you must show a material change in circumstances. If more than three years have passed since the last order, no material change needs to be shown at all.

What does filing cost, and how long does it take?

Kansas district courts charge a $62 filing fee as of January 2026, with a fee waiver available for income-qualified parents. Modification typically takes 4-6 weeks from motion filing to hearing, with the new amount retroactive to the first of the month following the filing date.

In short: Kansas's income shares guidelines were most recently updated effective July 1, 2025. Modification requires a material change within three years of the last order, or no showing at all once three years have passed, with a modest $62 filing fee and a 4-6 week timeline, plus a free DCF review option for enforcement-system cases.

What Kansas generally provides

The Kansas Child Support Guidelines, adopted by the Kansas Supreme Court and most recently updated effective July 1, 2025, use an income shares approach through the mandatory Child Support Worksheet, the same worksheet described in Kansas's custody guide for its role in the legal custody/residency/parenting-time framework.

Important terminology

Kansas Payment Center: the destination for withheld support under K.S.A. 23-3101.
3-year automatic eligibility: the point after which a modification doesn't require showing a material change at all.
DCF free review: a modification review path available at no cost for cases already in the state enforcement system.

How the calculation works

The mandatory worksheet, updated for 2025

Both parents' income runs through the Child Support Worksheet, following the guidelines the Kansas Supreme Court adopted and updated effective July 1, 2025, reflecting current economic data for the calculation.

Requesting or defending a modification

Within three years of the most recent order, a parent seeking a modification must show a material change in circumstances. Once more than three years have passed since the last order, no material change needs to be shown at all, a straightforward periodic reset. Kansas district courts charge a $62 filing fee as of January 2026, with a fee waiver available for income-qualified parents. The process typically takes 4-6 weeks from motion filing to a hearing date, and the modified amount is generally retroactive to the first of the month following the filing date. Separately, Kansas DCF Child Support Services offers free modification reviews for cases already in the state enforcement system, reachable through the Child Support Call Center at 1-888-757-2445. See the child support calculator and guideline finder for jurisdiction-specific calculation sources and guidance.

How enforcement works

Income withholding orders are mandatory for all new and modified child support orders under K.S.A. 23-3101, directing employers to withhold support directly from wages and send it to the Kansas Payment Center. Garnishment limits: up to 50% of disposable earnings if the paying parent currently supports another spouse or child, up to 60% if not, with an additional 5% for parents more than 12 weeks behind, and Kansas can also suspend or revoke driver's licenses for delinquent parents.

Common questions

Do I need to prove anything if it's been more than 3 years since my order? No, once three years have passed, Kansas doesn't require showing a material change at all, you can request a fresh calculation on that basis alone.

Is there a free way to get my order reviewed? Yes, if your case is in the state enforcement system, DCF Child Support Services offers free modification reviews without the district court filing fee.

What if my co-parent isn't paying? Contact the Kansas Payment Center or DCF Child Support Services, which can pursue income withholding and license suspension for delinquent parents.

Practical considerations

Because Kansas ties the modification standard so directly to whether three years have passed, mark that date on your order and use it as a natural checkpoint, especially if pursuing DCF's free review process rather than a district court filing. For the custody, residency, and parenting-time rules that intersect with this worksheet, see the Kansas custody guide.
