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 Washington State, both trial and appellate courts have established local rules of court that dictate the specifics of conducting legal proceedings within their jurisdiction. These rules cover a range of procedural aspects such as case assignment to judges, the filing and service of documents, scheduling of hearings, and communication protocols with opposing parties and court personnel. Similarly, federal courts, including United States district courts and courts of appeals, have their own set of local rules that must align with Acts of Congress and the Federal Rules of Practice and Procedure. The creation of these local rules is subject to public notice and comment, ensuring transparency and consistency with overarching legal frameworks. The authority for federal courts to establish local rules is found in various statutes and rules, including 28 U.S.C. §§ 2071(a)-(b) and the Federal Rules of Appellate, Bankruptcy, Civil, and Criminal Procedure. Both state and federal courts in Washington typically make their local rules available to the public on their official websites, providing attorneys and litigants with necessary guidance for legal practice in each court system.
