Interim Measures in International Arbitration

Temporary orders issued by arbitral tribunals to preserve rights or evidence pending the final award.

Updated April 23, 2026


How It Works in Practice

In international arbitration, disputes between parties—often states, companies, or investors—can be complex and time-consuming to resolve. Interim measures are temporary orders issued by the arbitral tribunal to maintain the status quo, protect assets, or preserve evidence while the arbitration is ongoing. These measures ensure that the final award is meaningful and enforceable by preventing parties from taking actions that could harm the arbitration process or the other party's interests.

For example, if one party fears that the other might dispose of critical evidence or transfer assets to avoid enforcement of a future award, they can request interim measures to freeze those assets or safeguard the evidence. The tribunal assesses such requests based on urgency, necessity, and the balance of interests between the parties.

Why Interim Measures Matter

Interim measures play a crucial role in ensuring fairness and efficiency in international arbitration. Without them, parties might engage in tactics that undermine the arbitration process, such as destroying evidence or dissipating assets. By granting interim relief, tribunals help maintain the integrity of the proceedings and protect the rights of all parties involved.

Moreover, interim measures can prevent irreparable harm that might occur before the arbitration concludes, making the final award more effective and credible. This is especially important in high-stakes disputes involving significant financial interests or sensitive political matters.

Interim Measures vs Injunctions

A common point of confusion is the difference between interim measures in arbitration and injunctions issued by courts. Injunctions are court orders that compel or restrain actions, while interim measures are issued by arbitral tribunals within the arbitration framework.

Unlike courts, arbitral tribunals do not always have direct enforcement power. Therefore, interim measures granted in arbitration may need to be confirmed or enforced by courts in the relevant jurisdiction. However, many arbitration rules explicitly empower tribunals to order interim relief, reflecting their importance in the dispute resolution process.

Real-World Examples

A notable example of interim measures occurred in a dispute between an investor and a state where the investor sought to prevent the state from seizing assets that could satisfy a potential arbitral award. The tribunal granted an interim order freezing those assets, ensuring that the investor's rights were protected pending the final decision.

Another case involved the preservation of crucial documents. The tribunal ordered a party to retain specific records and refrain from deleting electronic evidence, recognizing that without this protection, the arbitration could be compromised.

Common Misconceptions

One misconception is that interim measures guarantee immediate protection without any risk. In reality, tribunals carefully weigh the necessity and proportionality of such measures before granting them. They are temporary and subject to modification or revocation as the case develops.

Another misunderstanding is that interim measures are always enforceable globally. Enforcement depends on the jurisdiction and whether courts recognize and uphold the tribunal's orders. Thus, parties often seek court assistance to enforce interim measures effectively.

Summary

Interim measures in international arbitration are vital tools that help preserve rights, evidence, and assets while a dispute is being resolved. They maintain fairness and effectiveness in arbitration by preventing actions that could undermine the final award. Understanding how these measures function and their limitations is essential for parties engaged in international disputes.

Example

In a dispute over a multinational investment, the arbitral tribunal ordered an interim freeze on the respondent's assets to prevent dissipation before the final ruling.
