From or on one side only, with the other side absent or unrepresented.

Duhaime Legal Dictionary

Latin: for one party only.

Ex parte refers to those proceedings where one of the parties has not received notice and, therefore, is neither present nor represented.

If a person received notice of a hearing and chose not to attend, then the hearing would not be called ex parte.

Some jurisdictions expand the definition to include any proceeding that goes undefended, even though proper notice has been given.

On behalf of or involving only one party to a legal matter and in the absence of and usu. without notice to the other party.

Law.com Dictionary

Latin meaning "for one party," referring to motions, hearings or orders granted on the request of and for the benefit of one party only. This is an exception to the basic rule of court procedure that both parties must be present at any argument before a judge, and to the otherwise strict rule that an attorney may not notify a judge without previously notifying the opposition. Ex parte matters are usually temporary orders (like a restraining order or temporary custody) pending a formal hearing or an emergency request for a continuance. Most jurisdictions require at least a diligent attempt to contact the other party's lawyer of the time and place of any ex parte hearing.

Lat. 'By or for one party' or 'by one side.'

Refers to situations in which only one party (and not the adversary) appears before a judge. Such meetings are often forbidden.

Although a judge is normally required to meet with all parties in a case and not with just one, there are circumstances where this rule does not apply and the judge is allowed to meet with just one side (ex parte) such as where a plaintiff requests an order (say to extend time for service of a summons) or dismissal before the answer or appearance of the defendant(s).

In addition, sometimes judges will issue temporary orders ex parte (that is, based on one party's request without hearing from the other side) when time is limited or it would do no apparent good to hear the other side of the dispute. For example, if a wife claims domestic violence, a court may immediately issue an ex parte order telling her husband to stay away. Once he's out of the house, the court holds a hearing, where he can tell his side and the court can decide whether the ex parte order should be made permanent.

The Free (Legal) Dictionary

An ex parte judicial proceeding is conducted for the benefit of only one party. Ex parte may also describe contact with a person represented by an attorney, outside the presence of the attorney. The term ex parte is used in a case name to signify that the suit was brought by the person whose name follows the term.

Under the Fifth Amendment to the U.S. Constitution, "No person shall … be deprived of life, liberty, or property, without due process of law." A bedrock feature of due process is fair notice to parties who may be affected by legal proceedings. An ex parte judicial proceeding, conducted without notice to, and outside the presence of, affected parties, would appear to violate the Constitution. However, adequate notice of judicial proceedings to concerned parties may at times work irreparable harm to one or more of those parties. In such a case, the threatened party or parties may receive an ex parte court hearing to request temporary judicial relief without notice to, and outside the presence of, other persons affected by the hearing.

Ex parte judicial proceedings are usually reserved for urgent matters where requiring notice would subject one party to irreparable harm. For example, a person suffering abuse at the hands of a spouse or significant other may seek ex parte a Temporary Restraining Order from a court, directing the alleged abuser to stay away from him or her. Ex parte judicial proceedings are also used to stop irreparable injury to property. For example, if two neighbors, Reggie and Veronica, disagree over whose property a tree stands on, and Reggie wants to cut down the tree whereas Veronica wants to save it, Veronica can seek an ex parte hearing before a judge. At the hearing, she will ask the judge for a temporary Restraining Order preventing Reggie from felling the tree. She will have to show the judge that she had no reasonable opportunity to provide Reggie with formal notice of the hearing, and that she might win the case. The court will then balance the potential hardships to Reggie and Veronica, in considering whether to grant Veronica's request.
