 (from Ch. 38, par. 1005-9-3)Sec. 5-9-3. Default.(a) An offender who defaults in the payment of a fine or  any  installment of that fine may be held in contempt and imprisoned for nonpayment. The  court may issue a summons for his appearance or a warrant of arrest.(b) Unless the offender shows that his default was not due to his  intentional refusal to pay, or not due to a failure on his part to make a  good faith effort to pay, the court may order the offender imprisoned for a  term not to exceed 6 months if the fine was for a felony, or 30 days if the  fine was for a misdemeanor, a petty offense or a business offense. Payment  of the fine at any time will entitle the offender to be released, but  imprisonment under this Section shall not satisfy the payment of the fine.(c) If it appears that the default in the payment of a fine is not  intentional under paragraph (b) of this Section, the court may enter an  order allowing the offender additional time for payment, reducing the  amount of the fine or of each installment, or revoking the fine or the  unpaid portion.(d) When a fine is imposed on a corporation or unincorporated  organization or association, it is the duty of the person or persons  authorized to make disbursement of assets, and their superiors, to pay the  fine from assets of the corporation or unincorporated organization or  association. The failure of such persons to do so shall render them subject  to proceedings under paragraphs (a) and (b) of this Section.(e) A default in the payment of a fine, fee, cost, order of restitution, judgment of bond forfeiture, judgment order of forfeiture, or any installment thereof  may be  collected by any and all means authorized for the collection of money judgments. The State's Attorney of the county in which the fine, fee, cost, order of restitution, judgment of bond forfeiture, or judgment order of forfeiture was imposed may retain  attorneys and private collection agents for the purpose of collecting any  default in payment of any fine, fee, cost, order of restitution, judgment of bond forfeiture, judgment order of forfeiture, or installment thereof.  An additional fee of 30% of the delinquent amount  and  each taxable court cost including,  without limitation, costs of service of process, shall be charged to the offender for any amount of the fine, fee, cost, restitution, or judgment of bond forfeiture or installment of   the fine, fee, cost, restitution, or judgment of bond forfeiture that remains unpaid after the time fixed for payment of the fine, fee, cost, restitution, or judgment of bond forfeiture   by the court. The additional  fee shall be payable to the State's Attorney in order to compensate the State's Attorney for costs incurred in collecting the delinquent amount.  The State's Attorney may enter into agreements assigning any portion of the fee to the retained attorneys or the private collection agent retained by the State's Attorney. Any agreement between the State's Attorney and the retained attorneys or collection agents shall require the approval of the Circuit Clerk of that county.  A default in payment of a fine, fee, cost, restitution, or judgment of bond forfeiture shall draw interest at the rate of 9% per annum.  (Source: P.A. 98-373, eff. 1-1-14.)
