To file a motion for a temporary restraining order in federal court, you submit a written motion supported by sworn evidence, a proposed order, a certification about notice to the opposing party, and a security bond, then present it to the judge under your court’s emergency procedures. Federal Rule of Civil Procedure 65 governs the process, and if the judge grants the order it lasts no more than 14 days unless extended.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders The bar is high, the clock is short, and the paperwork carries most of the weight.
What You Have to Prove
Federal courts evaluate TRO motions using the four-factor test the Supreme Court laid out in Winter v. Natural Resources Defense Council, Inc. (2008). Weakness on any one factor can sink the motion.2Legal Information Institute. Preliminary Injunction
- Likelihood of success on the merits. Your underlying legal claim has to look strong enough that you will probably win when the case is fully decided. Judges do not freeze anyone’s conduct to protect a long-shot claim.
- Irreparable harm. You have to show injury serious enough that money cannot fix it later. This is the factor courts scrutinize most heavily. Routine financial losses almost never qualify. Loss of trade secrets, harm to reputation, deprivation of constitutional rights, and destruction of unique or irreplaceable property typically do.3Legal Information Institute. Irreparable Harm
- Balance of hardships. The court weighs your harm without the order against the burden the order puts on the other side. Asking a judge to shut down a whole business to protect a minor interest tips the balance against you.
- Public interest. The judge considers whether the order serves or damages the broader public, which carries extra weight in cases involving government regulations, public safety, or First Amendment rights.
Because a TRO decision happens so quickly, judges often lean harder on the irreparable harm factor and reserve deeper merits analysis for the preliminary injunction hearing that follows.
The Documents to Prepare
Sloppy paperwork kills TRO motions. Courts expect a complete package, and missing pieces give the judge an easy reason to say no.
The Motion and Proposed Order
The motion has to spell out exactly what conduct you want stopped. Vague requests fail. If you want a former employee barred from contacting your clients, say that, rather than asking the court to “prevent further harm to the business.” Attach a draft of the proposed order for the judge to sign. A ready-made template speeds things up and makes sure the order reflects what you actually asked for.
Keep the proposed order specific. “Defendant shall not contact plaintiff’s customers” is enforceable. “Defendant shall not interfere with plaintiff’s business” is vague enough to invite fights about compliance. Judges prefer narrow, clear commands because they are easier to enforce.
Sworn Evidence
Your motion has to be backed by sworn factual support, either through affidavits from people with firsthand knowledge or through a verified complaint signed under oath. This is where weak TRO motions fall apart. Generalized statements like “the defendant intends to cause harm” accomplish nothing. The sworn statements need concrete facts: dates, names, specific threatened actions, and why the harm is imminent. The court needs enough factual detail to conclude that irreparable injury will happen before the other side can be heard.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
Certification of Notice Efforts
Rule 65 requires your attorney to file a written certification describing what efforts were made to notify the opposing party and, if no notice was given, why it should be excused.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders Courts take this seriously. The most common justification for skipping notice is that tipping off the other side would prompt them to complete the very act you are trying to stop, like destroying evidence or transferring assets. If you can give notice, do so. Judges are far more comfortable granting a TRO when the other party at least knows what is happening, even without time to respond fully.
The Security Bond
Before a TRO takes effect, you post a security bond in an amount the court considers appropriate. The bond protects the restrained party: if the TRO turns out to have been wrongly issued, the bond covers their costs and any damages they suffered while the order was in place.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
Judges have broad discretion over the amount. A bond can be set at a nominal figure, or even zero, when the risk of harm to the restrained party is speculative or when a large bond would effectively block a meritorious claim from getting emergency relief. Opposing counsel sometimes pushes for a high bond precisely because posting it can be a financial barrier. If you work with a surety company rather than posting cash, expect a premium that typically runs a small percentage of the total bond amount. The federal government and its agencies are exempt from the bond requirement.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
Come in with a realistic number. Estimate what it would actually cost the other side to be wrongly restrained for up to 14 days and be ready to defend that figure. Proposing zero when the restrained party would clearly lose revenue looks unreasonable and erodes your credibility on the other factors.
Filing Under Emergency Procedures
Emergency motions do not follow the normal filing calendar. Most courts have specific procedures for emergency submissions, which often involve direct contact with the clerk’s office or the assigned judge’s chambers. Call ahead. Many courts require you to notify the clerk before filing, and failing to follow local emergency protocols can cost you hours or days you do not have.
Lead with the emergency. The first page of your motion should make the judge understand why waiting even a few days would cause irreversible damage. Save the detailed legal analysis for the memorandum of law that supports the motion.
The Ex Parte Hearing
If the motion is filed without notice to the opposing party, the court holds what is called an ex parte hearing, meaning only you or your attorney appears before the judge. These hearings are short and focused. The judge is not trying to resolve the entire case; the question is whether the emergency is real and whether the harm is truly irreparable. Be ready to walk the judge through your sworn evidence quickly and clearly. Oral argument matters more here than in most motions because the judge is making a fast decision on limited information.
When the judge grants the request, the TRO takes effect immediately. Every order issued without notice must state the date and hour it was issued, describe the injury and explain why it is irreparable, and explain why it was granted without notice to the other side.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders The order then has to be formally served on the restrained party before it can be enforced against them. Someone who has not been served with the TRO cannot be held in contempt for violating it.
What Happens After the Order Issues
A TRO expires at the time the court sets, which cannot exceed 14 days after entry. For good cause, the court can extend it once for another period of equal length, and the restrained party can consent to a longer extension.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders After that, the TRO simply dies. Ongoing protection requires a preliminary injunction, which is the longer-lasting order that can stay in place through the end of the lawsuit and typically requires formal notice to the opposing party.
A court that issues a TRO without notice must schedule the preliminary injunction hearing at the earliest possible time. That hearing takes priority over almost everything else on the docket. If you obtain the TRO and then fail to move forward with the preliminary injunction motion at the scheduled hearing, the court must dissolve the order.1Legal Information Institute. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders This is not a technicality judges overlook.
Winning the TRO is the beginning, not the finish line. The preliminary injunction hearing will be scheduled on a compressed timeline, the other side will be present, the evidence will be tested more thoroughly, and the judge will expect a more complete showing on all four factors. Treat the TRO as time to build that case.
When TROs Fit the Situation
TROs come up most often when money alone cannot fix the problem. A former employee about to hand trade secrets to a competitor is the classic example. Once confidential information is disclosed, no dollar amount unscrambles that egg. The same logic applies to someone threatening to destroy unique property, a company infringing intellectual property, or a party moving assets out of the court’s reach to dodge a judgment.
Reputational harm and violations of constitutional rights are other frequent triggers. If a government agency is about to enforce a regulation that would shut down a business or suppress speech, waiting weeks for a hearing could make the eventual legal victory meaningless. Environmental cases follow the same pattern: once a wetland is dredged or a reef is damaged, a court order issued after the fact accomplishes nothing.3Legal Information Institute. Irreparable Harm The thread connecting all these situations is that the harm, once it occurs, cannot be undone. If your problem does not fit that pattern, a TRO is unlikely to be the right tool, and the motion is unlikely to succeed.
