What is the term for all writs and official documents issued by courts in connection with pending lawsuits?

The term that refers to all writs and official documents issued by courts in connection with pending lawsuits is "process." This encompasses a variety of legal documents such as summonses, subpoenas, and other court orders that facilitate the judicial proceedings. "Process" is a broader term that captures the essential function of these documents in notifying parties, ensuring compliance, and managing the flow of a case through the court system.

In contrast, "summons" refers specifically to a document that notifies a defendant about a lawsuit being filed against them, requiring their appearance in court. "Pleadings" are formal written statements submitted by parties in a case which outline their respective claims or defenses. "Journals" typically refer to official court records documenting proceedings and decisions, but they do not encompass all types of documents generated in the course of a lawsuit. Therefore, "process" effectively represents the comprehensive nature of the court-issued documents required to facilitate legal proceedings.
