An injunction is a court order directing a party to do something or to stop doing something. It is one of the most powerful remedies available in civil litigation, capable of halting a competitor';s conduct, freezing assets, or protecting confidential information before a full trial takes place. For businesses operating across borders, understanding when an injunction applies - and how to obtain or resist one - can determine the outcome of a dispute.
This guide explains the legal definition of an injunction, the main types recognised across common law and civil law systems, the conditions courts apply before granting one, the procedural steps involved, and the practical consequences for international business.
An injunction is a judicial remedy that commands a named party to act in a specified way or to refrain from a specified course of conduct. Courts in most jurisdictions treat it as an equitable remedy, meaning it is granted at the court';s discretion rather than as an automatic right. The term derives from the Latin "injungere," meaning to enjoin or impose.
The defining feature of an injunction is its in personam character - it binds the individual or entity to whom it is addressed, not property or third parties generally. Breach of an injunction is treated as contempt of court, which can result in fines, asset seizure, or imprisonment of responsible officers. This enforcement mechanism gives the order its practical force.
In common law systems such as those of England and Wales, the United States, Canada, Australia, and Singapore, injunctions are a well-developed equitable remedy with centuries of case law behind them. Civil law systems in continental Europe, Latin America, and Asia have analogous provisional measures - known variously as "référé" in France, "einstweilige Verfügung" in Germany, or "medida cautelar" in Spanish-speaking jurisdictions - that serve similar functions, though the procedural rules differ considerably.
Courts recognise several distinct categories of injunction, each suited to a different stage or purpose in litigation.
A temporary restraining order (TRO) is the most urgent form. It is granted on an emergency basis, often without notice to the opposing party, and lasts only until a full hearing can be held - typically a matter of days. Courts grant TROs when the applicant can show that immediate, irreparable harm will occur before a proper hearing is possible.
An interim or interlocutory injunction is granted after both parties have had an opportunity to be heard, but before the final trial. Its purpose is to preserve the status quo while the substantive dispute is resolved. This is the form most commonly encountered in commercial litigation involving intellectual property, confidentiality breaches, or contractual non-compete clauses.
A permanent injunction is issued as part of the final judgment after a full trial. Despite the name, it need not last forever - it simply reflects the court';s final ruling on the merits rather than a provisional measure. A court may grant a permanent injunction instead of, or in addition to, damages where monetary compensation would be inadequate.
A mandatory injunction orders a party to take a positive action - for example, to restore access to a shared system, to deliver specific goods, or to remove an unlawful structure. Courts apply a higher threshold before granting mandatory injunctions because compelling action is generally considered more intrusive than restraining it.
A prohibitory injunction orders a party to stop doing something - the more common form. Typical examples include stopping the use of a trademark, ceasing publication of confidential data, or halting construction pending a planning dispute.
A freezing injunction (known in England as a Mareva injunction) restrains a party from disposing of or dissipating assets up to a specified value. It is used when there is a real risk that a defendant will move assets out of reach before judgment can be enforced. Freezing injunctions can extend to assets held in foreign jurisdictions, making them a critical tool in international commercial disputes.
A search order (formerly Anton Piller order) allows an applicant to enter premises and inspect or seize evidence without prior notice. It is reserved for cases where there is a strong likelihood that evidence would otherwise be destroyed.
Courts do not grant injunctions automatically. The applicant must satisfy a structured legal test, the precise formulation of which varies by jurisdiction but follows a broadly consistent logic across common law systems.
The leading English formulation, derived from the House of Lords decision in American Cyanamid Co v Ethicon Ltd, requires the applicant to show three things. First, there must be a serious question to be tried - the claim must not be frivolous or vexatious. Second, the balance of convenience must favour granting the order - the harm to the applicant if the injunction is refused must outweigh the harm to the respondent if it is granted. Third, damages must be an inadequate remedy - if money could fully compensate the applicant, a court will generally prefer that route.
Many jurisdictions add a further requirement: the applicant must give an undertaking in damages. This means the applicant promises to compensate the respondent for any loss caused by the injunction if the applicant ultimately loses at trial. The undertaking is a significant financial commitment and courts may require security to be lodged.
In civil law systems, the equivalent provisional measures typically require the applicant to demonstrate urgency ("fumus boni juris" - a plausible legal basis) and the risk of serious or irreparable harm if the measure is not granted. The procedural timelines and evidentiary standards differ, but the underlying policy balance is similar.
For freezing injunctions, courts apply a higher threshold. The applicant must show a good arguable case on the merits, that the respondent holds assets within the jurisdiction, and that there is a real risk of dissipation. Courts are alert to the risk that freezing orders can be used oppressively, and they scrutinise applications carefully.
The process for obtaining an injunction moves quickly by litigation standards, but it still requires careful preparation.
The applicant begins by filing an application supported by a witness statement or affidavit setting out the facts, the legal basis for the claim, and the specific relief sought. In urgent cases, the application is made without notice to the respondent - known as an ex parte application. The applicant has a strict duty of full and frank disclosure, meaning all material facts, including those that might weigh against granting the order, must be placed before the court. Failure to disclose material facts is a ground for discharging the injunction and can expose the applicant to a costs order.
If the court grants an ex parte order, a return date is set - usually within a few days - at which the respondent can appear and argue that the injunction should be discharged or varied. At this inter partes hearing, both sides present evidence and submissions, and the court decides whether to continue the injunction until trial.
Once an injunction is granted, it must be served on the respondent promptly and correctly. In many jurisdictions, personal service is required. The order should also be served on relevant third parties - for example, banks in the case of a freezing injunction - to ensure they are bound by its terms.
Enforcement is through contempt proceedings. If a party breaches an injunction, the applicant can apply to the court for a finding of contempt. Penalties range from fines to committal to prison for individual officers of a corporate respondent. In practice, the threat of contempt is usually sufficient to secure compliance.
In practice, founders should consider that obtaining an injunction in a foreign jurisdiction requires local counsel familiar with both the procedural rules and the temperament of the local courts. Timing is critical - delay in applying can itself be used by the respondent to argue that the situation is not truly urgent.
Scenario one: intellectual property dispute between competitors
A technology company discovers that a former employee has joined a competitor and is using proprietary source code. The company cannot wait months for a full trial - by then the code will have been embedded in a competing product. The company applies on an emergency basis for a TRO and then an interlocutory injunction restraining the competitor from using, copying, or distributing the code. The court grants the TRO within 48 hours. At the inter partes hearing a week later, the injunction is continued on the basis that damages would be inadequate to compensate for the loss of competitive advantage. The undertaking in damages is secured by a bank guarantee.
Scenario two: cross-border asset protection
A trading company has obtained an arbitral award against a counterparty but suspects the counterparty is transferring assets to offshore accounts to avoid enforcement. The company applies to the English High Court for a worldwide freezing injunction. The court grants the order, restraining the respondent from disposing of assets up to the value of the award anywhere in the world. Copies of the order are served on banks in multiple jurisdictions. The respondent, faced with the practical impossibility of moving funds, agrees to negotiate a settlement.
A common mistake in cross-border injunction applications is underestimating the disclosure obligation. Applicants sometimes present only the facts that support their case, omitting inconvenient details. Courts take this seriously - an injunction obtained by incomplete disclosure is vulnerable to immediate discharge, and the applicant may be ordered to pay the respondent';s costs on an indemnity basis.
Many underestimate the cost and speed of injunction proceedings. Emergency applications require experienced counsel available at short notice, detailed supporting evidence prepared quickly, and the financial capacity to provide an undertaking in damages. Professional fees for a contested interlocutory injunction in a major commercial court can reach significant sums even before the substantive trial begins.

International commercial contracts frequently include arbitration clauses. A common question is whether a party can seek an injunction from a national court when the underlying dispute is subject to arbitration.
Most jurisdictions allow national courts to grant interim relief - including injunctions - in support of arbitration, even where the arbitral tribunal has jurisdiction over the merits. The English Arbitration Act, the UNCITRAL Model Law, and the rules of major arbitral institutions such as the ICC and LCIA all contemplate court-ordered interim measures running alongside arbitral proceedings.
The arbitral tribunal itself can also order interim measures in many institutional rules. The ICC Rules, for example, allow an emergency arbitrator to be appointed within days to grant urgent relief before the main tribunal is constituted. The LCIA Rules contain similar provisions. These emergency arbitrator procedures have become an important alternative to court injunctions in international commercial disputes, particularly where the parties have chosen a neutral seat of arbitration.
A non-obvious requirement is that a party seeking court-ordered interim relief in support of arbitration must typically notify the arbitral tribunal and, in some jurisdictions, obtain its permission. Failure to do so can be treated as a waiver of the arbitration agreement or as conduct inconsistent with the agreement to arbitrate.
What is the difference between an injunction and a court order to pay damages?
An injunction and a damages award are both court remedies, but they operate differently. Damages are a monetary payment compensating the claimant for loss already suffered. An injunction is a behavioural command - it tells a party to act or stop acting in a specific way. Courts grant injunctions when money cannot adequately compensate the harm, for example where the loss is ongoing, difficult to quantify, or involves unique assets such as intellectual property or confidential information. In some cases a court will grant both remedies: an injunction to stop the harmful conduct and damages for the loss already caused. The choice between them depends on what the claimant actually needs to protect their position.
How long does it take to obtain an injunction, and what does it cost?
An emergency TRO can be obtained within 24 to 72 hours in most major commercial courts. An interlocutory injunction following a contested hearing typically takes one to three weeks from the initial application. A permanent injunction is granted only at the end of a full trial, which may take months or years. Costs vary significantly by jurisdiction, complexity, and whether the application is contested. Professional fees for an emergency application in a major commercial court generally start in the mid-to-high thousands and can rise substantially for contested multi-day hearings. The applicant must also factor in the potential liability under the undertaking in damages if the injunction is later discharged.
Can an injunction be challenged or reversed?
An injunction can be challenged in several ways. The respondent can apply to discharge the order on the grounds that the applicant failed to make full and frank disclosure, that the balance of convenience does not support the order, or that circumstances have changed since the order was made. The respondent can also appeal the decision to a higher court. If the applicant ultimately loses at trial, the injunction will be discharged and the respondent can seek compensation under the undertaking in damages. Courts also have inherent jurisdiction to vary the terms of an injunction - for example, to allow specific transactions that would otherwise be caught by a freezing order - where the respondent can show a legitimate need.
An injunction is a court order compelling or restraining conduct, available in both common law and civil law systems as a powerful tool for protecting rights before or after trial. Its effectiveness depends on acting quickly, preparing evidence carefully, and understanding the specific procedural rules of the relevant court or arbitral institution. For international businesses, injunctions - particularly freezing orders and emergency arbitral measures - are often the decisive step in protecting assets and enforcing rights across borders.
