Modifying Maintenance in Kansas
In Kansas, the court may modify maintenance not yet due, retroactive to a date at least one month after the motion was filed, but it cannot increase or accelerate the paying spouse’s liability beyond the original decree without his or her consent.
Amounts not yet due
At any time, on a hearing with reasonable notice to the party affected, the court may modify the amounts or other conditions for the payment of any portion of the maintenance originally awarded that has not already become due (K.S.A. 23-2903). Payments that are already due cannot be changed.
The consent rule
No modification may be made without the consent of the party liable for the maintenance if it has the effect of increasing or accelerating the liability for the unpaid maintenance beyond what the original decree prescribed. A recipient can therefore ask for a reduction or a longer schedule, but cannot force an increase on the payor.
Retroactive modification
The court may make a modification retroactive to a date at least one month after the date the motion to modify was filed (23-2904). File promptly: a change cannot reach back before that point.
Terms in the decree
The decree may make payments modifiable or terminable under circumstances it prescribes (23-2902(c)), so the first question is always what your decree says. A decree that makes maintenance non-modifiable cannot be changed under this section.
Evidence to gather
The decree, before-and-after income and expense records, proof of the changed circumstances and the date the motion was filed and served.
Documents to gather
The decree, proof of the change in circumstances with dates and the date the motion was filed and served.
