(65 ILCS 5/11-12-12) (from Ch. 24, par. 11-12-12)
    Sec. 11-12-12. No map or plat of any subdivision presented for record affecting land (1) within the corporate limits of any municipality which has heretofore adopted, or shall hereafter adopt an ordinance including an official map in the manner prescribed in this Division 12, or (2) within contiguous territory which is not more than 1 1/2 miles beyond the corporate limits of an adopting municipality, shall be entitled to record or shall be valid unless the subdivision shown thereon provides for streets, alleys, public ways, ways for public service facilities, storm and flood water run-off channels and basins, and public grounds, in conformity with the applicable requirements of the ordinances including the official map; provided, that a certificate of approval by the corporate authorities, certified by the clerk of the municipality in whose jurisdiction the land is located, or a certified copy of an order of the circuit court directing the recording as provided in Section 11-12-8, shall be sufficient evidence of compliance with this section upon which the recorder may accept the plat for recording.
    The provisions of this Section do not apply to any plat for consolidation of 2 or more contiguous parcels, located within any territory that is outside of the corporate limits of a municipality but within a county that has adopted a subdivision ordinance and that has a population of more than 250,000, into a smaller number of parcels if the sole purpose of the consolidation is to bring a non-conforming parcel into conformance with local zoning requirements. The exemption created by this amendatory Act of the 92nd General Assembly does not apply to a plat for consolidation for an area in excess of 10 acres or to any consolidation that results in a plat of more than 10 individual lots following the consolidation. If the county receives a request to approve a plat for consolidation pursuant to this Section, the county must notify all municipalities located within 1 1/2 miles of the subject property within 10 days after receiving the request.
