(810 ILCS 5/3-806) (from Ch. 26, par. 3-806)
    Sec. 3-806. Any person who issues a check or other draft that is not honored upon presentment because the drawer does not have an account with the drawee, or because the drawer does not have sufficient funds in his account, or because the drawer does not have sufficient credit with the drawee, shall be liable in the amount of $25, or for all costs and expenses, including reasonable attorney's fees, incurred by any person in connection with the collection of the amount for which the check or other draft was written, whichever is greater, and shall be liable for interest upon the amount of the check or other draft at the rate provided in subsection (1) of Section 4 of the Interest Act. Costs and expenses shall include reasonable costs and expenses incurred in the nonlitigated collection of the check or other draft.
    A person who undertakes a nonlitigated collection against the person who issued a check or other draft that is not honored upon presentment shall make a written demand by certified mail, return receipt requested, delivered to the last known address of that person in order to become eligible for any costs and expenses in excess of $25. The written demand shall demand payment within 30 days of the mailing of the demand and shall include notice of liability for the costs and expenses.
    A fee or charge not to exceed $4.50 may be assessed to any person or owner of a commercial checking account or other similar commercial account where a check or other draft that is deposited into the account is dishonored upon presentment because of insufficient funds or because the drawer does not have an account with the drawee; provided, however, that, the limitation on the fee or charge specified in this paragraph does not apply to any fee or charge assessed to any bank or other depository institution or to any non-commercial checking account or other similar non-commercial account.
