Illinois Code § 9-2-132

§ 9-2-132.

Any property owner may pay his assessment wholly or in part, either before or after it is due, and whether or not the assessment has been withdrawn from collection or the property assessed has been sold to any municipality or forfeited to the State for nonpayment of that assessment, with the bonds or vouchers heretofore or hereafter issued under this Division 2 on account of that assessment, applying, however, bonds issued under Section 9-2-119 and vouchers of each series only to the payment of the installments to which they relate. If bonds issued under Section 9-2-127 are used to make such payments, such bonds may be applied to the payment of any and all installments, but only such of those bonds may be used as are next in numerical order of redemption at the time of making such payments. In making such payments, the vouchers and bonds shall be taken at their par value and interest accrued to the date of making the payment. All vouchers and bonds received in payment of such an assessment shall be cancelled by the officer receiving the vouchers, or bonds, as of the date of their receipt, and then deposited with the treasurer or the comptroller, as the case may be, of the municipality issuing the vouchers or bonds. However, when the amount of the assessment is less than that of a bond or voucher, the officer receiving the same shall issue a receipt for the balance which shall entitle the owner to the same rights, except as to negotiability, as if the receipt were the original bond or voucher in the amount of the balance. Any such indorsement on any such bond or voucher shall be made by writing or stamping across the face thereof the words "payments upon this bond (or voucher) are listed upon the back."
