Civil procedure includes the procedures and rules that govern civil (non-criminal) litigation in state and federal courts. Many states have rules of civil procedure written by the state supreme court, for example, and other states include their rules of procedure in state statutes enacted by the state legislature.
In New Hampshire, civil procedure is governed by the New Hampshire Rules of Civil Procedure, which are promulgated by the New Hampshire Supreme Court. These rules outline the procedures for conducting civil litigation in the state's courts and cover various aspects of the legal process, including filing complaints, serving documents, conducting discovery, and trial procedures. Additionally, certain aspects of civil procedure may also be addressed in state statutes enacted by the New Hampshire Legislature. These statutes can provide additional details or modifications to the procedural rules. It's important to note that federal courts have their own set of rules, known as the Federal Rules of Civil Procedure, which govern civil litigation in federal courts. These federal rules apply when a case is brought under federal jurisdiction, either due to federal law or a diversity of citizenship among the parties involved.
