Kan. Stat. § 60-2611
In any civil action to enforce payment of or to collect upon a check, order or draft on any bank, credit union, savings and loan association or depository for the payment of money or its equivalent, payment upon which such instrument has been refused because of insufficient funds or no account, the party prevailing on such cause of action shall be awarded reasonable attorney fees. Such fees shall be assessed by the court as costs against the losing party. The fees shall not be allowed unless the plaintiff offers proof during the trial of such action that prior to the filing of the petition in the action demand for payment of the check, order or draft had been made upon the defendant by first class mail not less than 14 days prior to the filing of such suit.
