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 Nevada, ex parte hearings or ex parte relief are legal proceedings where the court hears and decides on an urgent matter 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 that could occur if immediate action is not taken by the court. Examples of situations that may warrant ex parte relief include, but are not limited to, the imminent threat of a child being removed from the state, instances of domestic violence, or the theft of trade secrets. Nevada law requires that the party seeking ex parte relief demonstrate the urgency and necessity of such an order, and typically, the affected party must be given notice and an opportunity to be heard as soon as possible after the ex parte order is issued. The standards and procedures for ex parte relief are governed by the Nevada Revised Statutes and the rules of the specific court in which the matter is being heard.
