735 ILCS 5/12-101
With respect to the creation of liens on real estate by judgments, all real estate in the State of Illinois is divided into 2 classes.
The first class consists of all real property, the title to which is registered under "An Act concerning land titles", approved May 1, 1897, as amended.
The second class consists of all real property not registered under "An Act concerning land titles".
As to real estate in class one, a judgment is a lien on the real estate of the person against whom it is entered for the same period as in class two, when Section 85 of "An Act concerning land titles", has been complied with.
As to real estate included within class two, a judgment is a lien on the real estate of the person against whom it is entered in any county in this State, including the county in which it is entered, only from the time a transcript, certified copy or memorandum of the judgment is filed in the office of the recorder in the county in which the real estate is located. The lien may be foreclosed by an action brought in the name of the judgment creditor or its assignee of record under XV in the same manner as a mortgage of real property, except that the redemption period shall be 6 months from the date of sale and the real estate homestead exemption under Section 12-901 shall apply. A judgment resulting from the entry of an order requiring child support payments shall be a lien upon the real estate of the person obligated to make the child support payments, but shall not be enforceable in any county of this State until a transcript, certified copy, or memorandum of the lien is filed in the office of the recorder in the county in which the real estate is located. Any lien hereunder arising out of an order for support shall be a lien only as to and from the time that an installment or payment is due under the terms of the order. Further, the order for support shall not be a lien on real estate to the extent of payments made as evidenced by the records of the Clerk of the Circuit Court or State agency receiving payments pursuant to the order. In the event payments made pursuant to that order are not paid to the Clerk of the Circuit Court or a State agency, then each lien imposed by this Section may be released in the following manner:
YOU ARE HEREBY NOTIFIED THAT ON (insert date) THE ATTACHED AFFIDAVIT WAS FILED IN THE OFFICE OF THE RECORDER OF.... COUNTY, ILLINOIS, WHOSE ADDRESS IS........ , ILLINOIS. IF, WITHIN 28 DAYS OF THE DATE OF THIS NOTICE, YOU FAIL TO FILE AN AFFIDAVIT OBJECTING TO THE RELEASE OF THE STATED JUDGMENT LIEN OR LIENS, IN THE ABOVE OFFICE, SUCH JUDGMENT LIEN WILL BE DEEMED TO BE RELEASED AND NO LONGER SUBJECT TO FORECLOSURE. THIS RELEASE OF LIEN WILL NOT ACT AS A SATISFACTION OF SUCH JUDGMENT.
A judgment is not a lien on real estate for longer than 7 years from the time it is entered or revived, unless the judgment is revived within 7 years after its entry or last revival and a new memorandum of judgment is recorded prior to the judgment and its recorded memorandum of judgment becoming dormant.
When a judgment is revived it is a lien on the real estate of the person against whom it was entered in any county in this State from the time a transcript, certified copy or memorandum of the order of revival is filed in the office of the recorder in the county in which the real estate is located.
A foreign judgment registered or filed pursuant to Sections 12-630 through 12-672 of this Act is a lien upon the real estate of the person against whom it was entered only from the time (1) a copy of the affidavit required by Section 12-653 with a copy of the foreign judgment attached showing the filing in a court of this State or (2) a transcript, certified copy or memorandum of a final judgment of the court of this State entered on an action to enforce a foreign judgment is filed in the office of the recorder in the county in which the real estate is located. However, no such judgment shall be a lien on any real estate registered under "An Act concerning land titles", as amended, until Section 85 of that Act has been complied with.
The release of any transcript, certified copy or memorandum of judgment or order of revival which has been recorded shall be filed by the person receiving the release in the office of the recorder in which such judgment or order has been recorded.
Such release shall contain in legible letters a statement as follows:
FOR THE PROTECTION OF THE OWNER, THIS RELEASE SHALL BE FILED WITH THE RECORDER OR THE REGISTRAR OF TITLES IN WHOSE OFFICE THE LIEN WAS FILED.
The term "memorandum" as used in this Section means a memorandum or copy of the judgment signed by a judge or a copy attested by the clerk of the court entering it and showing the court in which entered, date, amount, number of the case in which it was entered, name of the party in whose favor and name and last known address of the party against whom entered. If the address of the party against whom the judgment was entered is not known, the memorandum or copy of judgment shall so state.
The term "memorandum" as used in this Section also means a memorandum or copy of a child support order signed by a judge or a copy attested by the clerk of the court entering it or a copy attested by the administrative body entering it.
This Section shall not be construed as showing an intention of the legislature to create a new classification of real estate, but shall be construed as showing an intention of the legislature to continue a classification already existing.
