Illinois Code § 7-1-32

§ 7-1-32.

If the specified authorities agree as to the amount to be paid by the enlarged annexing municipality, each of the authorities concerned shall pass an ordinance or a resolution reciting the amount to be paid. A certified copy of the ordinance or resolution shall be filed by the clerk of the annexing municipality with the county clerk of the county in which the annexing municipality is situated. The county clerk shall send a certified copy to the State Auditor of Public Accounts. This ordinance or resolution shall be conclusive as to the amount of indebtedness and liabilities to be assumed and paid by the enlarged annexing municipality. If the authorities cannot agree, the matter shall be determined by the circuit court of the county in which the annexing municipality is situated, upon a petition of either municipality or of any taxpayer of either municipality. The court shall hear the controversy without further pleadings, and without a jury, and then shall pronounce a judgment in accordance with the rule of apportionment stated in Section 7-1-31. A certified copy of the judgment shall be filed with the clerk of each municipality and with the county clerk of the county in which the annexing municipality is situated. The county clerk shall send a certified copy of the judgment to the State Auditor of Public Accounts. The judgment shall be final and conclusive as to the indebtedness and liabilities to be assumed and paid by the enlarged annexing municipality. The State Auditor shall not thereafter certify any tax rate to the county clerk, nor shall the county clerk extend any tax rate upon the taxable property of the annexed part for the payment of any of the bonds, or interest thereon, issued by the municipality from which the part was disconnected.
