Kan. Stat. § 23-3111
If an obligor derives income from self-employment, receives income from some source not subject to the jurisdiction of the court or receives income by any other method which makes the application of this act impracticable, the court may require the obligor to post security or bond or give some other guarantee to secure the payment of current and overdue support. If the obligor fails to pay support as ordered, the court may collect on the bond or may declare a forfeiture of all or a portion of the security or other guarantee and apply the amounts collected as payment on the support arrearage. An obligor who derives income from self-employment shall be subject to the provisions of this act as a payor of income to the obligor's self.
