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 Maryland, both state and federal courts operate under specific local rules of court that govern the details of legal proceedings. These rules cover various aspects such as case assignments, document filing and service, hearing schedules, and communication protocols with opposing parties and court staff. Maryland state courts, including trial and appellate courts, have their own set of local rules that must be followed. Similarly, federal courts within the state, such as the United States district courts and courts of appeals, also have local rules that are consistent with Acts of Congress and the Federal Rules of Practice and Procedure. The federal courts' local rules are established in accordance with statutory authority and procedural rules, including 28 U.S.C. §§ 2071(a)-(b) and various Federal Rules (Appellate Procedure 47, Bankruptcy Procedure 9029, Civil Procedure 83, and Criminal Procedure 57), and are subject to a public comment period before they can be prescribed. Both state and federal courts in Maryland typically make their local rules available to the public on their official websites.
