State courts (both trial and appellate courts) usually have local rules of court that include detailed requirements for proceedings in the court—including the assignment of cases to judges, filing and serving documents, securing hearings before the court, and communicating with opposing parties and court personnel.

And federal courts (United States district courts and courts of appeals) also frequently prescribe local rules governing practice and procedure in their courts. Such rules must be consistent with both Acts of Congress and the Federal Rules of Practice and Procedure, and may only be prescribed after notice and an opportunity for public comment. A federal court's authority to prescribe local rules is governed by both statute and the Federal Rules of Practice and Procedure. See 28 U.S.C. §§ 2071(a)-(b); Fed. R. App. P. 47; Fed. R. Bankr. P. 9029; Fed. R. Civ. P. 83; Fed. R. Crim. P. 57.

State and federal courts usually post local rules on their websites.

In New York, both state and federal courts have established local rules of court that govern the procedural aspects of legal proceedings. For state courts, including trial and appellate courts, these local rules cover a range of topics such as case assignment to judges, the filing and serving of documents, scheduling hearings, and communication protocols with opposing parties and court personnel. These rules are designed to ensure the smooth operation of the court system and may vary from one jurisdiction to another within the state. On the federal level, the United States district courts and courts of appeals in New York also have their own set of local rules. These rules must align with Acts of Congress and the Federal Rules of Practice and Procedure. The authority to create these local rules is provided by statute (28 U.S.C. §§ 2071(a)-(b)) and various Federal Rules (Appellate Procedure 47, Bankruptcy Procedure 9029, Civil Procedure 83, and Criminal Procedure 57). The process of establishing or amending local rules includes a period of public notice and the opportunity for public comment. Both state and federal courts in New York typically make their local rules available to the public on their official websites.
