Service of process is the procedure by which a party to a lawsuit gives an 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. Typically, it involves providing the party or entity with court documents, such as summonses, complaints, and subpoenas, ensuring that they are informed and can respond appropriately. The process ensures that everyone has a right to know when they are facing legal actions and is a foundational concept in the justice system to ensure fair proceedings.
