The owner or owners of record of any area of land consisting of one or more tracts, lying within the corporate limits of any fire protection district, which (1) is located on the border of the fire protection district; (2) if disconnected will not result in the isolation of any part of the fire protection district from the remainder of the district; and (3) is adjacent to another fire protection district may, with the consent of the boards of trustees of the disconnecting and annexing district, have such area disconnected from the district and added to the adjacent district as follows:
The owner or owners of record of any such area of land shall file a petition in the court in which the fire protection district from which disconnection is sought was organized, alleging facts showing that such area meets the requirements of this Section. If the court finds that the allegations of the petition are true, that the area of land meets the requirements of this Section, and that the boards of trustees of the disconnecting and annexing districts consent to the transfer of such area, the court shall order the specified land disconnected from the one district and transferred to the other, and such land shall thenceforth cease to be a part of the fire protection district of which it was a part and shall become an integral part of the fire protection district to which transfer was sought and shall be subject to all the enjoyments and responsibilities of the latter district. In each case in which a transfer is effected under this Section, the circuit clerk in whose court the transfer proceedings were conducted shall certify copies of the transfer order and file or send them to the proper county clerk or clerks for filing and to the Office of the State Fire Marshal.
