55 ILCS 5/3-5046
Upon the recording or filing of a quitclaim deed on any property within a county with a population of 3,000,000 or more, the recorder of deeds must mail a notification postcard to the previous owner of record at the address listed on the property record in the recorder's office.
The postcard must state that a newly recorded quitclaim deed has been filed on the property, and must state the date of the new recording, the address of the recorder's office, and any other information deemed necessary by the recorder.
No county, including a home rule county, may act in a manner inconsistent with this Section. This Section is a denial and limitation of home rule powers under subsection (i) of Section 6 of Article VII of the Illinois Constitution.
