An Illinois Injunction Bond is a type of surety bond required by the state of Illinois when a party seeks an injunction from the court. An injunction is a court order that requires a party to either stop a certain action or to take a certain action. The purpose of an injunction bond is to protect the other party from any losses or damages resulting from the injunction. The two types of Illinois Injunction Bonds are Mandatory Injunction Bonds and Prohibitory Injunction Bonds. A Mandatory Injunction Bond is required when the court orders the defendant to take action, and the bond guarantees that the defendant will comply with the court’s order. A Prohibitory Injunction Bond is required when the court orders the defendant to refrain from taking a certain action, and the bond guarantees that the defendant will not take the proscribed action.
