How Federal Cases Are Filed and Initiated

Federal case initiation is a formally structured process governed by the Federal Rules of Civil Procedure (FRCP) for civil matters and the Federal Rules of Criminal Procedure (FRCrP) for criminal matters — both administered under the authority of the Supreme Court and codified through Title 28 of the United States Code. This page explains the mechanisms by which civil complaints, criminal indictments, and other initiating documents are filed in U.S. District Courts, the procedural steps that follow initial filing, and the decision boundaries that determine which court, which division, and which procedural track applies to a given case.

Definition and Scope

Case initiation in federal court refers to the formal act of submitting a legally sufficient document — most commonly a complaint, indictment, information, or petition — that opens a docket, assigns a case number, and triggers the court's jurisdiction over the matter. The U.S. District Courts serve as the primary trial-level entry point for nearly all federal litigation, handling both original civil filings and the initial stages of federal criminal prosecutions.

Federal jurisdiction must exist before any case can proceed. Under 28 U.S.C. § 1331, district courts have original jurisdiction over all civil actions arising under the Constitution, federal laws, or treaties — commonly called federal question jurisdiction. Under 28 U.S.C. § 1332, diversity jurisdiction applies when the parties are citizens of different states and the amount in controversy exceeds $75,000. A case filed without a valid jurisdictional basis faces dismissal under Federal Rule of Civil Procedure 12(b)(1).

The broader landscape of federal court jurisdiction, including the categories of cases courts may hear, directly shapes which initiation path applies.

How It Works

Civil and criminal initiations follow distinct procedural tracks, though both converge on the same district court clerk's office as the filing gateway.

Civil case initiation proceeds through the following steps:

1. Complaint drafting — The plaintiff prepares a complaint meeting the pleading standards of FRCP Rule 8, which requires a short and plain statement of the claim showing entitlement to relief.
2. Filing with the clerk — The complaint is submitted to the district court clerk, either in person or through the Electronic Case Filing (ECF) system, which the federal judiciary operates through the PACER platform (Public Access to Court Electronic Records).
3. Payment of filing fee — As of the fee schedule maintained by the U.S. Courts, the standard civil filing fee in U.S. District Court is $405. Indigent plaintiffs may seek a fee waiver under 28 U.S.C. § 1915. Additional detail on costs and waivers appears on the Federal Court Filing Fees and Waivers page.
4. Issuance of summons — The clerk issues a summons, which the plaintiff must serve on each defendant alongside a copy of the complaint per FRCP Rule 4.
5. Case assignment — The case receives a docket number and is assigned to a district judge, often with a magistrate judge designated for pretrial matters under 28 U.S.C. § 636.

Criminal case initiation follows a different track:

1. Charging instrument — A federal prosecutor (U.S. Attorney's Office) either presents evidence to a grand jury, which returns an indictment, or files a criminal information directly for lesser offenses where the defendant waives grand jury rights under the Fifth Amendment.
2. Grand jury threshold — For felony charges, indictment by a grand jury of 23 citizens is constitutionally required (U.S. Const. amend. V). The grand jury applies a probable cause standard — lower than the trial standard of beyond a reasonable doubt.
3. Initial appearance — Following arrest or summons, the defendant appears before a magistrate judge within the timeframe required by FRCrP Rule 10 for arraignment.

Common Scenarios

Federal cases are initiated across a range of substantive contexts, each with a characteristic initiating document and procedural posture.

• Constitutional litigation — A plaintiff alleging a federal civil rights violation under 42 U.S.C. § 1983 or a Bivens claim against a federal officer files a civil complaint asserting federal question jurisdiction. See Federal Civil Rights Cases for the full framework.
• Federal criminal prosecution — A federal grand jury in one of the 94 U.S. District Court districts returns an indictment after a U.S. Attorney presents evidence of a federal offense. The Federal Prosecutors and U.S. Attorneys page details prosecutorial roles.
• Bankruptcy proceedings — Debtors initiate cases by filing a voluntary petition in a U.S. Bankruptcy Court, a unit of the district court system under 28 U.S.C. § 151. The Federal Bankruptcy Court Process covers that pathway separately.
• Removal from state court — A defendant in a state court action with federal question or diversity jurisdiction may remove the case to federal district court by filing a notice of removal under 28 U.S.C. § 1441 within 30 days of service.

Decision Boundaries

Several threshold determinations control whether a filing proceeds, which court receives it, and which rules govern it.

Civil vs. Criminal initiation is the most fundamental division. Civil cases are initiated by private parties (or the government acting in a civil capacity) through a complaint. Criminal cases are initiated exclusively by the government through a grand jury indictment or a filed information — no private party may initiate a federal criminal prosecution.

Venue selection governs which of the 94 district courts receives the filing. Under 28 U.S.C. § 1391, civil venue is proper in any district where a defendant resides, where a substantial part of the events giving rise to the claim occurred, or where any defendant is subject to personal jurisdiction. Criminal venue is governed by the Constitution's requirement (U.S. Const. art. III, § 2) that trial occur in the state where the crime was committed, implemented through FRCrP Rule 18.

Statute of limitations operates as a hard deadline before initiation. Federal civil statutes carry varying limitation periods — for example, personal injury claims against the United States under the Federal Tort Claims Act carry a 2-year filing deadline under 28 U.S.C. § 2401(b). The Federal Court Deadlines and Statutes of Limitations page catalogs key limitation periods by case type.

Pro se filing is procedurally available — individuals may initiate cases without counsel under the same FRCP rules governing represented parties — but courts apply the same jurisdictional and pleading requirements. The Representing Yourself in Federal Court page details procedural obligations for self-represented filers.
