An ex parte hearing or ex parte relief refers to a situation in which the judge only hears from one party to a dispute before making a decision on some limited issue being presented to the court. Because fairness and due process of law generally require both sides of a dispute to receive notice of a hearing and the opportunity to be heard at the hearing, there must be an emergency situation in which harm that cannot be undone (irreparable harm) will occur if the court does not act immediately—without giving the other party notice and the opportunity to be heard on the disputed issue.

Emergency matters that justify ex parte relief might include the theft of trade secrets by a former employee, or, in a child custody dispute, removing the child from the state, domestic violence, drug and alcohol abuse, sexual abuse of the child, and other situations that put the child in immediate danger.

In Ohio, ex parte hearings or ex parte relief are legal proceedings where the court hears and decides on an urgent issue presented by one party without the presence or participation of the other party. This type of relief is granted only in exceptional circumstances where there is a substantial risk of irreparable harm if immediate action is not taken. Ohio law recognizes the importance of due process, which typically requires that both parties are given notice and the opportunity to be heard. However, in emergency situations such as the risk of a child being removed from the state, domestic violence, theft of trade secrets, or any scenario where a delay could result in significant harm, the court may issue ex parte orders. These orders are temporary and are typically followed by a full hearing where both parties can present their case. The Ohio Rules of Civil Procedure and relevant statutes outline the specific requirements and procedures for obtaining ex parte relief.
