An Illinois Complaint in Repletion is a type of civil lawsuit, brought in Illinois state court, in which a plaintiff seeks the return of personal property that has allegedly been wrongfully taken or detained by the defendant. The plaintiff must allege facts to show that the property in question is his/hers, and that the defendant has wrongfully taken it or is wrongfully withholding it. If the court determines that the plaintiff has established these facts, it may order that the property be returned to the plaintiff. There are two types of Illinois Complaint in Repletion: a standard complaint and a motion for a writ of repletion. A standard complaint is a civil action filed in an Illinois state court, which is usually the first step in seeking the return of property wrongfully taken or detained. A motion for a writ of repletion is a more urgent type of complaint, in which the plaintiff asks the court to issue an immediate order requiring the defendant to return the property.
