To get someone declared a vexatious litigant, you file a motion in the court handling the abusive litigation, document a clear pattern of meritless cases against them, and ask the judge at a hearing to enter a pre-filing order that requires judicial permission before that person can file anything new. The process differs between state and federal courts, but the core sequence is the same: prove the pattern, notice the other side, argue it at a hearing, and get a written order the clerk’s office can enforce.
Confirm the Person Actually Qualifies
A vexatious litigant is not someone who simply files a lot of lawsuits. Courts look for a pattern of abuse: cases filed without any real legal basis, litigation kept alive to drain the other side, or repeated attempts to relitigate issues a court already decided.
Common qualifying conduct includes filing numerous lawsuits that end in dismissal or judgment against the filer, refiling the same claims against the same defendants after losing, filing endless motions within a single case that serve no legitimate purpose, and having already been declared vexatious by another court. Many state statutes set a look-back window and a minimum number of failed cases before the designation applies.
One point that catches movants off guard: in many state courts, vexatious litigant statutes apply only to self-represented parties. If the person filing has an attorney, the statute may not reach them, and you may need to rely on Rule 11 or the equivalent sanction against the lawyer instead. Federal courts take a broader view and can restrict any litigant, though whether the target has counsel is one of the factors judges weigh.
Decide Whether You Are in State or Federal Court
The legal authority you invoke depends on the forum.
State Court
Many states have specific vexatious litigant statutes that spell out the criteria, the motion process, and the remedies. These statutes typically define vexatious conduct, set a look-back period, and authorize pre-filing orders. Some state courts maintain public lists of people subject to pre-filing orders, which clerks check when new cases come in.
State statutes also frequently allow courts to require a vexatious litigant to post a security bond covering the defendant’s anticipated legal costs. If the litigant does not post it by the court’s deadline, the case is dismissed. The judge sets the amount based on the circumstances. Even in states without a dedicated statute, courts retain inherent authority to manage their dockets and sanction abusive filers.
Federal Court
Federal courts have no single vexatious litigant statute. They rely on two sources of authority. The All Writs Act authorizes federal courts to “issue all writs necessary or appropriate in aid of their respective jurisdictions,” which courts have read to include pre-filing injunctions against serial frivolous filers.1Office of the Law Revision Counsel. 28 U.S. Code 1651 – Writs Federal courts also have inherent authority, recognized by the Supreme Court, to manage their proceedings and sanction misconduct.
When a federal court weighs a pre-filing injunction, it typically evaluates five factors drawn from Safir v. United States Lines, Inc.: whether the litigant’s history includes harassing or duplicative lawsuits, the litigant’s motive, whether the litigant has counsel, whether the filings have imposed needless expense on others or burdened the court, and whether lesser sanctions would be adequate. Federal courts treat these injunctions as a drastic remedy, require notice and an opportunity to be heard, and insist that the order be narrowly tailored.
Build the Evidence Before You File
The motion lives or dies on the record. Judges need to see an unmistakable pattern, not a handful of annoying cases.
Pull the Litigation History
Gather certified copies of prior rulings, dismissals, and judgments from every case the person filed that ended badly for them. Courts want to see the outcomes, not just the filing records. Build a chronological summary that lists each case, the court, the claims raised, and how it ended. Include out-of-state filings if you can find them, since many statutes and the federal factors both consider litigation history across jurisdictions.
Federal records are searchable through PACER. State court records are usually available through individual court websites or statewide judicial branch portals, though coverage varies. Paid litigation analytics tools aggregate docket data across jurisdictions.
Show the Impact
Beyond the raw case list, courts want to see the damage. Declarations or affidavits from attorneys, former defendants, or other people pulled into the frivolous cases give firsthand accounts of the financial and personal toll. Document your own legal costs with invoices and billing records. If the filings forced you to miss work, relocate, or absorb reputational harm, put that in writing.
Draft and File the Motion
Your motion should identify the court and case, name the person you want designated, and expressly ask the court to enter a pre-filing order. In state courts with a dedicated statute, cite the statute and walk through each element. In federal court, invoke the court’s inherent authority and the All Writs Act, and address the factors for pre-filing injunctions.
Attach a memorandum of law that connects your legal argument to the evidence. Organize the exhibits so the pattern is easy to follow. Number each exhibit, reference it in the brief, and use your chronological summary as the thread that ties everything together. A judge looking at twenty exhibits wants a roadmap.
Filing fees for civil motions vary by jurisdiction, typically from under $50 to several hundred dollars. Check the local fee schedule before filing. You will also need to serve the motion on the opposing party so they have notice and time to respond.
The Hearing
After the response window closes, the court sets a hearing. You or your attorney will walk the judge through the documented pattern, referencing specific cases, outcomes, and the timeline. Some courts allow witnesses, such as former defendants or attorneys from the earlier cases, to testify.
The person you are trying to designate gets a chance to respond. They can argue that their cases had merit, that adverse outcomes were procedural rather than substantive, or that they have legitimate reasons for their litigation activity. Judges take this rebuttal seriously, because restricting access to the courts is not something they do lightly. This is where a weak motion falls apart. If the evidence is thin or the pattern is ambiguous, the other side’s explanations may be enough to defeat it.
The judge then evaluates the full record against the applicable legal standard. In federal court, the judge works through the pre-filing injunction factors and must explain the reasoning on the record.
What the Court Can Order
If the court agrees the person qualifies, the usual remedy is a pre-filing order. That order requires the person to get permission from a judge before filing any new lawsuit. The designated litigant must submit a proposed complaint to the presiding judge, who reviews it for merit before allowing it to proceed. Filings submitted without permission are subject to automatic dismissal.
Pre-filing orders are typically limited to cases where the person is representing themselves. If the litigant later hires an attorney, that may satisfy the court that frivolous filings are less likely, though the order generally remains in effect until formally vacated.
Judges have other tools. A court may deny the full designation but still impose heightened procedural requirements, issue a formal warning, or require a security bond covering the defendant’s anticipated costs. In federal court, Rule 11 sanctions add another layer: if a filing violates the rule’s requirement that claims be supported by law and fact, the court can impose reprimands, monetary sanctions, or orders to pay the opposing party’s attorney fees.2Legal Information Institute (LII) at Cornell Law School. Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions
If the court finds the evidence insufficient, it denies the motion and the person keeps filing freely. A denial does not prevent you from bringing the motion again later with stronger evidence.
Recovering Your Costs
Defending against frivolous lawsuits is expensive, and courts have mechanisms to shift some of that cost. In federal court, a statute allows courts to require any attorney or party admitted to practice who “multiplies the proceedings in any case unreasonably and vexatiously” to personally pay the excess costs, expenses, and attorney fees their conduct caused.3Office of the Law Revision Counsel. 28 U.S. Code 1927 – Counsels Liability for Excessive Costs This statute targets the conduct, not the designation, so it can apply before a formal label is entered.
Many state vexatious litigant statutes also authorize costs and fees for defendants who successfully move for designation or who defend against claims filed in violation of a pre-filing order. The security bond in some states serves a similar function, set at an amount intended to cover reasonable expenses if the case turns out to be meritless. Fee recovery is not automatic. You generally need to file a separate motion and document what you spent, and the court decides whether the amounts are reasonable.
Enforcement After the Order Is Entered
A pre-filing order only works if it is enforced. In courts that maintain a vexatious litigant list, the clerk’s office checks incoming filings against the list and rejects new cases that lack the required judicial approval. If a filing slips through, the opposing party can notify the court, which typically stays the case and dismisses it if the litigant does not obtain retroactive permission within a short window.
Deliberately ignoring a pre-filing order is treated seriously. Courts have inherent authority to hold people in contempt for disobeying court orders, and that authority extends to pre-filing orders. Contempt sanctions can include fines, and in cases of willful and repeated defiance, imprisonment is possible.4Congress.gov. Inherent Powers Over Contempt and Sanctions In practice, monetary sanctions and dismissal of the unauthorized filing are far more common than incarceration.
Note one limit: a pre-filing order from one jurisdiction does not automatically bind courts elsewhere. It is, however, strong evidence in any future vexatious litigant motion filed in another court, and some state statutes expressly count prior designations as a qualifying criterion.
Appeals and Removal
A person declared a vexatious litigant can challenge the designation on appeal. In federal court, the notice of appeal must be filed within 30 days of the order in most civil cases, or 60 days if a government party is involved.5Legal Information Institute (LII) at Cornell Law School. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right When Taken State deadlines vary but tend to fall in a similar range. The appellate court reviews whether the lower court followed the correct legal standards and had enough evidence to support the decision.
Many jurisdictions also allow a designated litigant to petition the original court to vacate the pre-filing order later. The petitioner generally must show a material change in circumstances and that lifting the order would serve the interests of justice. If a petition is denied, there is usually a waiting period before the person can try again. A well-documented order backed by a strong record is difficult to overturn and creates a meaningful barrier against continued abuse.
