To file a civil complaint in federal court, you draft a document that meets Federal Rule of Civil Procedure 8, file it with the clerk through the court’s electronic filing system along with a civil cover sheet and the $405 filing fee, and then arrange for the defendant to be served within 90 days. Each step has its own rules, and skipping any of them can cost you the case before a judge ever reads your allegations.
What the Complaint Must Contain
Rule 8 sets the floor. Your complaint needs a short, plain statement of why the court has jurisdiction, a short, plain statement of the claim showing you’re entitled to relief, and a demand for the specific relief you want.1Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading Rule 10 handles the form: a caption at the top with the court’s name, a title listing all parties, a file number (the clerk assigns this after filing), and a designation identifying the document as a complaint. The body is broken into numbered paragraphs, each covering a single point, so the defendant can answer them one by one.2Legal Information Institute. Rule 10 – Form of Pleadings
Jurisdiction
Before the story of what happened, you have to explain why this court can hear the case. Federal question jurisdiction under 28 U.S.C. § 1331 covers claims based on a federal law or the U.S. Constitution.3Office of the Law Revision Counsel. 28 USC 1331 – Federal Question Jurisdiction Diversity jurisdiction under 28 U.S.C. § 1332 applies when the parties are citizens of different states and the amount in controversy exceeds $75,000; for class actions, the threshold is $5,000,000.4Office of the Law Revision Counsel. 28 USC 1332 – Diversity of Citizenship In a diversity case, state each party’s state of citizenship in the complaint. If you are self-represented, the U.S. Courts website publishes a Pro Se Complaint Form that walks you through these jurisdictional facts.5United States Courts. Civil Pro Se Forms
Facts, Claims, and Relief
The factual section describes what happened, paragraph by paragraph: specific events, interactions, transactions. After the facts, you identify your causes of action, which are the legal theories tying those facts to the law. A financial dispute might include breach of contract, breach of fiduciary duty, or a statutory claim like one under the Fair Debt Collection Practices Act.6Federal Trade Commission. Fair Debt Collection Practices Act Each cause of action must link the facts to a specific legal violation. Under the Supreme Court’s plausibility standard, factual allegations have to make the claim believable on its face; a complaint built on labels, conclusions, or a formulaic recitation of elements will be dismissed.
The complaint ends with the prayer for relief: the dollar damages you want, any injunction ordering the defendant to stop (or start) doing something, or a declaratory judgment clarifying rights.1Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading You can request multiple or alternative remedies. Be precise. The prayer frames what the court can award.
Attaching Exhibits
If a written contract, promissory note, or similar document is central to the claim, attach it. Under Rule 10(c), a written instrument attached as an exhibit becomes part of the complaint for all legal purposes.2Legal Information Institute. Rule 10 – Form of Pleadings Attach the document rather than paraphrasing it.
What You Certify by Signing
Signing the complaint is a representation to the court. Under Rule 11, you certify that the filing is not for an improper purpose like harassment or delay, that the legal arguments are supported by existing law or a reasonable argument to change it, that the factual allegations have evidentiary support or will likely have it after discovery, and that any denials are warranted by the evidence.7Legal Information Institute. Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions
If those certifications are false, the court can impose sanctions limited to what is needed to deter the same conduct, including orders to pay the other side’s attorney’s fees or a penalty paid to the court. Law firms are jointly responsible for violations by their attorneys absent exceptional circumstances. There is a safety valve: if the other side moves for sanctions, you have 21 days to withdraw or correct the filing before the motion goes to the court.
Filing Before the Deadline Runs
Every civil claim has a filing deadline, and missing it usually ends the case. For federal claims created by statutes enacted after December 1, 1990, the default limitations period is four years from when the cause of action accrues, though many federal statutes set their own period. Securities fraud, for instance, must be filed within two years of discovering the violation or five years after the violation itself, whichever is earlier.8Office of the Law Revision Counsel. 28 US Code 1658 – Time Limitations on the Commencement of Civil Actions
State-law claims have their own deadlines that vary by state and claim type. When you file in federal court under diversity jurisdiction, the state limitations period typically applies. Equitable tolling can occasionally extend a deadline when the plaintiff was unaware of the harm through no fault of their own, but courts treat these requests skeptically. If you aren’t sure your deadline is still open, resolve that question first.
Filing the Complaint With the Clerk
Federal courts use the Case Management/Electronic Case Files (CM/ECF) system for filing, and documents must be submitted as PDFs.9United States Courts. Electronic Filing (CM/ECF) PACER is a separate system for viewing court records, not for filing.10PACER. File a Case The clerk reviews your submission, assigns a case number, and that number appears on every document filed afterward.
Fees and Fee Waivers
Opening a new civil action in a federal district court costs $350 as the base filing fee plus a $55 administrative fee set by the Judicial Conference, totaling $405.11Office of the Law Revision Counsel. 28 US Code 1914 – District Court; Filing and Miscellaneous Fees If you cannot afford that, you can apply to proceed in forma pauperis under 28 U.S.C. § 1915 by submitting an affidavit detailing your assets and stating you are unable to pay. If the court grants it, you proceed without prepaying fees.12Office of the Law Revision Counsel. 28 USC 1915 – Proceedings In Forma Pauperis State court fees are different and vary widely, from under $100 to several hundred dollars depending on the jurisdiction and case type.
Civil Cover Sheet and Required Redactions
You also submit a JS-44 Civil Cover Sheet. It asks for the basis of jurisdiction, the nature of the suit, how the case originated, and whether you’re requesting a jury trial. It is a docketing tool for the clerk, not a substitute for the complaint.13United States Courts. Civil Cover Sheet
Rule 5.2 requires certain information to be redacted before anything is filed. Social Security numbers and financial account numbers get trimmed to the last four digits, birth dates to the year only, and minors identified by initials only.14Legal Information Institute. Rule 5.2 – Privacy Protection For Filings Made with the Court The clerk will not catch these for you. Filing unredacted personal information without sealing it waives the protection for that data.
Serving the Defendant
Filing opens the case. The defendant isn’t officially in it until served with a copy of the complaint and a summons directing them to respond. The delivery must be made by a disinterested third party, not you. Professional process servers typically charge $20 to $100 per job.15National Association of Professional Process Servers. How Much Does a Process Server Cost Once served, the defendant has 21 days to file an answer or a motion to dismiss.16Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections The server then files a proof of service with the court showing how and when the papers were delivered.
Waiver of Service
You can ask the defendant to waive formal service by mailing a copy of the complaint with a waiver form. The defendant has at least 30 days to return the waiver, or 60 days if they are outside the United States. The incentive is real: a defendant who waives gets 60 days to respond instead of 21. If a defendant inside the United States refuses to waive without good cause, the court must order them to pay the expenses of formal service, including attorney’s fees for any motion needed to collect those costs.17Legal Information Institute. Rule 4 – Summons
Serving a Business
You cannot just hand papers to anyone at the front desk. Under Rule 4(h), a corporation or partnership must be served by delivering the summons and complaint to an officer, a managing or general agent, or another agent authorized to accept service. You can also follow the service rules of the state where the court sits or where service is being made. Corporations can also be asked to waive service, with the request addressed to an authorized agent.17Legal Information Institute. Rule 4 – Summons
The 90-Day Deadline
You have 90 days from filing the complaint to complete service. Miss it, and the court can dismiss the case without prejudice on its own initiative or on the defendant’s motion.18United States Courts. Federal Rules of Civil Procedure Dismissal without prejudice lets you refile, but if the statute of limitations has run while you were trying to serve, that door may be closed. If you can show good cause for the delay, the court must grant an extension. The 90-day limit does not apply to service in a foreign country.
Fixing the Complaint After Filing
Rule 15 gives you one amendment as a matter of course, with no permission required. You have 21 days after serving the complaint to amend, or if the defendant files a response or a motion to dismiss, 21 days after that response, whichever is earlier.19Legal Information Institute. Rule 15 – Amended and Supplemental Pleadings After that window, you need the other side’s written consent or the court’s permission. Courts tend to allow early amendments, but patience shortens the later the request comes, especially if you want to add new claims or parties. Use the free amendment deliberately.
If the Defendant Doesn’t Respond
If the defendant is properly served and files nothing, you can ask the clerk to enter a default. For claims seeking a specific dollar amount, the clerk can enter default judgment directly. For anything else, you go before a judge, who may hold a hearing to determine damages or verify the claim before entering judgment.20Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 55 – Default; Default Judgment Default judgment cannot be entered against the United States unless the plaintiff establishes the claim with satisfactory evidence, and a minor or incapacitated person must have a representative in the case before any default can apply. Defective service is a common reason default judgments get set aside, which is why the service steps earlier in this article are worth getting right the first time.
