How to File a Pro Se Motion to Dismiss

8 min readProSeAI Editorial

What Is a Motion to Dismiss?

A motion to dismiss asks the court to throw out a case — or specific claims within a case — before it proceeds to discovery or trial. As a self-represented litigant, filing a motion to dismiss is one of the most powerful early tools available to you.

Common Grounds for a Motion to Dismiss

Under Federal Rule of Civil Procedure 12(b), a defendant may move to dismiss for the following reasons:

  • Lack of subject matter jurisdiction (12(b)(1)) — the court does not have authority to hear this type of case
  • Lack of personal jurisdiction (12(b)(2)) — the court does not have authority over you specifically
  • Improper venue (12(b)(3)) — the case was filed in the wrong court location
  • Insufficient process (12(b)(4)) — the summons was defective
  • Insufficient service of process (12(b)(5)) — you were not properly served
  • Failure to state a claim (12(b)(6)) — even if everything the plaintiff says is true, they have no legal claim
  • Failure to join a required party (12(b)(7))

The most commonly used ground in pro se litigation is 12(b)(6) — failure to state a claim. This argument says: "Even accepting all of the plaintiff's allegations as true, they have not described a legal violation."

Step-by-Step: How to File a Motion to Dismiss

Step 1: Read the Complaint Carefully

Before drafting anything, read the complaint line by line. Identify every claim the plaintiff is making. For each claim, ask: what law are they relying on, and what facts do they allege to support it?

Step 2: Research the Legal Standard

For a 12(b)(6) motion, the standard is whether the complaint contains "sufficient factual matter, accepted as true, to state a claim to relief that is plausible on its face." (Ashcroft v. Iqbal, 556 U.S. 662 (2009); Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007)). These two Supreme Court cases are the foundation of every 12(b)(6) argument.

Step 3: Draft the Motion

Your motion should include:

  1. Caption — court name, case number, parties, and title ("DEFENDANT'S MOTION TO DISMISS PURSUANT TO FRCP 12(b)(6)")
  2. Introduction — one paragraph summarizing why dismissal is warranted
  3. Statement of Facts — brief summary of the case background
  4. Legal Standard — cite Iqbal and Twombly
  5. Argument — for each claim, explain why it fails the pleading standard
  6. Conclusion — request that the court dismiss the complaint with prejudice
  7. Certificate of Service — confirm you served the opposing party

Step 4: Check Local Rules

Every federal and state court has local rules that govern motion formatting. Common requirements include:

  • Page limits (typically 25 pages for dispositive motions)
  • Font size and margin requirements
  • Whether a memorandum of law must be filed separately
  • Whether a proposed order must be attached

Step 5: File and Serve

File your motion with the clerk's office (in person or via the court's electronic filing system). Serve a copy on the opposing party by the method specified in the court's rules, and file a certificate of service.

Timing

Under FRCP 12(b), a motion to dismiss must be filed before or simultaneously with your answer. If you have already filed an answer, you may still raise some of these defenses in a motion for judgment on the pleadings under FRCP 12(c).

What Happens Next?

The opposing party will typically have 14–21 days to file a response. You may then file a reply brief. The court will either rule on the papers or schedule oral argument.
