735 ILCS 5/2-1305
A party intending to move to set aside any judgment, bond or other proceeding may apply to the court or to the judge in chamber for a certificate (which the judge may, in his or her discretion, grant) that there is probable cause for staying further proceedings until the order of the court on the motion. Service of a copy of the certificate at the time of or after the service of the notice of the motion stays all further proceedings accordingly. In no case shall the judge grant the certificate if the error complained of may, by the direction of the judge to the clerk issuing the process, be corrected, but the judge shall order and the clerk shall make the correction in the process, nor unless the applicant has given notice of the motion to the opposite party, or his or her attorney of record, if they or either of them can be found in the county where the judgment was entered.
