Yes, a restraining order is a type of injunction, but the two terms are not interchangeable. An injunction is the broad legal category: any court order telling someone to do something or stop doing something. A restraining order is one narrow application of that concept, almost always aimed at protecting a person’s physical safety. Every restraining order functions as an injunction. Most injunctions have nothing to do with restraining orders.
What an Injunction Does
An injunction is a court order that either compels a party to take a specific action or, more commonly, prohibits them from doing something. Courts turn to injunctions when money alone would not fix the problem. A technology company might get an injunction to stop a former engineer from sharing trade secrets. A city might seek one to halt a construction project that violates zoning rules. A business partner might obtain one to prevent the other partner from selling shared assets while a lawsuit plays out.
To obtain a preliminary injunction in federal court, the person requesting it must satisfy four requirements: a likelihood of winning the underlying case, a likelihood of suffering harm that cannot be undone without the court’s intervention, a balance of hardships that favors granting the order, and that the injunction serves the public interest.1Justia. Winter v. Natural Resources Defense Council, Inc. State courts apply similar tests, though the exact wording varies.
One practical feature of general injunctions surprises many people. In federal cases, the court can require the party seeking the injunction to post a security bond. That bond covers the other side’s costs and damages if the court later decides the injunction should never have been issued. The federal government is exempt from this bond requirement.2Legal Information Institute. Rule 65 Injunctions and Restraining Orders The bond requirement generally does not apply to domestic violence restraining orders, which run on a different procedural track.
What a Restraining Order Does
A restraining order takes the injunction concept and narrows it to personal safety. Courts issue these orders in cases involving domestic violence, stalking, harassment, or sexual assault. The goal is to create a legally enforceable barrier between someone who poses a threat and the person they are threatening.
A typical restraining order includes several restrictions on the person it covers. A no-contact provision prohibits all communication with the protected person, including phone calls, texts, emails, and social media messages. A stay-away provision requires the restrained person to maintain a set physical distance from the protected person’s home, workplace, school, and vehicle. A firearms surrender provision requires the restrained person to give up any firearms and ammunition they possess, and it can trigger a separate federal prohibition.
How the Two Differ in Practice
The purpose is the first dividing line. A general injunction can protect almost any legal interest — intellectual property, contractual rights, property, the environment. A restraining order protects a person. That difference drives most of the others.
The burden of proof is lower for a restraining order than for the criminal cases that often run alongside it. Most states require the petitioner to show by a preponderance of the evidence — more likely than not — that the alleged threat or abuse occurred. A few states apply a somewhat higher “clear and convincing evidence” standard. Both are significantly easier to meet than the “beyond a reasonable doubt” threshold used in criminal cases.
The procedural posture also differs. A general injunction usually sits inside a larger lawsuit over money, property, or conduct. A restraining order typically stands on its own, filed on a dedicated civil track built to move quickly.
The Three Durations Both Share
Whether labeled an injunction or a restraining order, protective court orders come in three forms based on how long they last and how much process is required to get them.
Temporary Restraining Order
A temporary restraining order is emergency-level protection. In federal court, it expires no later than 14 days after it is issued, though a judge can extend that period for good cause.2Legal Information Institute. Rule 65 Injunctions and Restraining Orders State timeframes vary but follow the same general principle: these orders are short-lived by design. A judge can grant one based entirely on the petitioner’s testimony, without the other party being present or even notified, when there is a credible threat of immediate harm that cannot wait for a full hearing.
Preliminary Injunction
Once a temporary order expires, the court may replace it with a preliminary injunction after holding a hearing where both sides present their evidence and arguments. This order preserves the status quo for a longer stretch, often for the duration of the underlying lawsuit. The four-factor test applies here in full.1Justia. Winter v. Natural Resources Defense Council, Inc.
Permanent Injunction
A permanent injunction is issued only after a full trial on the merits or as part of a settlement agreement. Despite the name, these orders are often set for a defined period, anywhere from one to several years, though they can be indefinite in serious cases. The court must find conclusive evidence that the harm would continue without the order and that no other remedy would adequately protect the petitioner.
The Firearms Consequence Unique to Qualifying Restraining Orders
This is where restraining orders diverge most sharply from ordinary injunctions. Under federal law, anyone subject to a qualifying domestic violence restraining order is prohibited from possessing any firearm or ammunition.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The prohibition applies automatically by operation of federal law. The state court order does not need to mention it.
For the prohibition to kick in, the restraining order must meet three criteria. The restrained person must have received actual notice and had an opportunity to participate in the hearing. The order must restrain them from harassing, stalking, or threatening an intimate partner or that partner’s child. And the order must either include a finding that the person poses a credible threat to the physical safety of the partner or child, or explicitly prohibit the use or threatened use of physical force against them.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Temporary ex parte orders issued without notice to the restrained person do not trigger this federal prohibition because the notice-and-hearing requirement is not met.
The penalty for violating the firearm prohibition is up to 15 years in federal prison.4Office of the Law Revision Counsel. 18 USC 924 – Penalties In 2024, the U.S. Supreme Court confirmed that the prohibition is constitutional under the Second Amendment, holding that a person found by a court to pose a credible threat to another’s physical safety may be temporarily disarmed.5Supreme Court of the United States. United States v. Rahimi A general commercial or civil injunction carries no equivalent consequence.
Cross-State Enforcement
A restraining order does not lose its force when the protected person or the restrained person crosses a state line. Under the Violence Against Women Act, every state, tribal government, and U.S. territory must honor and enforce a valid protection order issued by any other jurisdiction in the country as if it were their own.6Office of the Law Revision Counsel. 18 USC 2265 – Full Faith and Credit Given to Protection Orders
Two conditions must be met. The issuing court had jurisdiction over the parties and the subject matter, and the restrained person received reasonable notice and an opportunity to be heard. For ex parte orders, notice must be provided within the time required by the issuing jurisdiction’s law and in any event within a reasonable time afterward.6Office of the Law Revision Counsel. 18 USC 2265 – Full Faith and Credit Given to Protection Orders
The federal definition of “protection order” is deliberately broad. It covers any injunction, restraining order, or other court order issued to prevent violent acts, threats, harassment, sexual violence, or unwanted contact or proximity, whether temporary or permanent, civil or criminal.7Office of the Law Revision Counsel. 18 USC 2266 – Definitions Child custody, visitation, and support provisions included within a protection order also carry over. The protected person does not need to register the order in the new state before it can be enforced; the law specifically says enforcement cannot be conditioned on prior registration or filing.6Office of the Law Revision Counsel. 18 USC 2265 – Full Faith and Credit Given to Protection Orders A general injunction between private parties has no equivalent cross-state recognition statute.
