When you ask a court to stop someone from doing something right now, a former business partner draining a shared account, a competitor using your trade secrets, a contractor about to demolish the wrong structure, you are asking for powerful relief on short notice. Courts take that seriously. Before a judge will grant a temporary restraining order or a preliminary injunction, they usually require you to post security first. That security is an injunction bond.
The logic is fair when you think about it. The court is about to restrain someone based on your side of the story, before the case has been fully decided. If it later turns out you were wrong, the restrained party may have lost real money sitting on the sidelines. The injunction bond is there to make them whole.

What an injunction bond does
An injunction bond guarantees that if the court later finds the restraining order or injunction was wrongly issued, the party you restrained can recover the costs and damages they suffered while it was in place. It does not pay your legal fees and it is not a fine. It is a safety net for the other side, required as a condition of getting the relief you asked for.
In federal court this requirement lives in Rule 65(c) of the Federal Rules of Civil Procedure, which states that a restraining order or preliminary injunction may issue only if the applicant gives security in an amount the court considers proper. Most states have a parallel rule in their own courts, so the same basic structure applies whether your case is federal or state.
TRO vs. preliminary injunction: where the bond fits
These two often get lumped together, but they sit at different points on the timeline. A temporary restraining order is the emergency, short-term step, sometimes granted within hours and often before the other side has even been heard. A preliminary injunction comes a bit later, after both sides have had a chance to argue, and it lasts until the case is resolved.
A bond can be required at either stage. Because a TRO moves so fast, the bond requirement can land on you with very little notice, which is exactly why it helps to know how the process works before you are standing in front of a judge. If you want a plain-English visual of how restraining orders unfold, our temporary restraining order infographic lays it out step by step.
Who decides the bond amount?
The judge does, and they have wide discretion. Rule 65(c) says the security must be in an amount the court considers proper, which means there is no fixed formula. A judge will weigh how much the restrained party could plausibly lose if the order turns out to be wrong, and set the figure accordingly. For a dispute over a high-value contract or business operation, that number can be substantial.
Courts can also adjust or, in limited situations, waive the requirement, and government entities are generally exempt. But for most private disputes, you should plan on posting a bond, and you will usually learn the amount when the court grants or conditions the order.
How to get an injunction bond fast
Speed is the whole game here, because these orders move quickly. To issue the bond we need the case information, the court-ordered bond amount, and some basic details about you or your business. Because the surety is taking on the risk that the order is later found wrongful, larger injunction bonds may involve underwriting and, in some cases, collateral. The sooner you reach out, ideally as soon as you know a bond is likely, the more smoothly it goes when the judge sets the number. You can learn more on our injunction bond page.
Frequently asked questions
Why do I have to post a bond to get an injunction?
Because the court is restraining someone before the case is decided. The bond protects that party so they can recover costs and damages if the injunction is later found to have been wrongly issued. Under Rule 65(c), security is generally required as a condition of the order.
How much is an injunction bond?
There is no set formula. The judge sets the amount based on how much the restrained party could lose if the order proves wrongful. It can range from modest to very large depending on what is at stake.
What is the difference between a TRO and a preliminary injunction?
A TRO is the emergency, short-term order, often granted very fast and sometimes without the other side present. A preliminary injunction comes after both sides are heard and lasts until the case is resolved. A bond can be required for either.
Can the bond requirement be waived?
Sometimes. Courts have discretion to lower or waive security in limited situations, and government applicants are typically exempt. For most private disputes, plan on posting a bond.
How quickly can I get one?
Often very quickly once we have the case details and the court-ordered amount. Because these orders move on tight timelines, it helps to contact us as early as possible.
