735 ILCS 5/16-104
No relief by ne exeat shall be granted but upon complaint or petition filed, and affidavit to the truth of the allegation therein contained. Upon the granting of such relief the court shall enter an order stating in what penalty bond and security shall be required of the defendant or respondent. The court shall also require the plaintiff or petitioner, before a certified copy of the ne exeat order is issued by the clerk, bond with good and sufficient surety, in such sum as the court shall deem proper, conditioned that the plaintiff or petitioner will prosecute the complaint or petition with effect, and will reimburse to the defendant or respondent such damages and costs as shall be wrongfully sustained by occasion of the granting of the relief by ne exeat. If any defendant or respondent to any such relief by ne exeat is damaged, he or she may bring an action on such bond; and, if, on trial, it is determined by the court that such relief by ne exeat was applied for without just cause, the person affected shall recover damages, to be assessed as in other cases on penal bonds.
