Process service, also known as "service of process,” is the procedure employed to give appropriate notice of initial legal action to another party (such as a defendant), court, or administrative body in an effort to exercise jurisdiction over that person so as to enable that person to respond to the proceeding before the court, body, or other tribunal. Notice is furnished by delivering a set of court documents (called "process") to the person to be served.
