Arbitration Procedure

Unlike other institutions, we monitor the entire arbitral process—from the initial request for arbitration to scrutiny of the draft final award. If it is necessary to enforce an ICC Award, we can also assist parties in complying with the required formalities. The current version of the ICC Rules of Arbitration came into force on 1 June 2026.

Go directly to:

Request for Arbitration, Answer to Request, Emergency Arbitrator, Provisional Advance, and Joinder of Additional Parties.

The Request for Arbitration is registered on the day it is received by the Secretariat of the International Court of Arbitration®. Parties are encouraged to file their Request electronically, by ICC Case Connect or by email to the ICC Registry team based at ICC Headquarters in Paris. Where parties request notification in hard copy, Requests may be filed at any of the offices of the Secretariat listed here. Further information on filing the Request can be found here.

The Secretary General acknowledges receipt of the Request and indicates to the Claimant the names and contact details of the counsel and other members of the dedicated team in charge of the file.

As soon as the Request is complete and the filing fees are paid, the counsel that has been assigned the case transmits the Request to the Respondent. The Respondent shall submit the Answer (or Answers) to the Request, together with any counterclaims, within 30 days.

The arbitration will proceed and the arbitral tribunal shall decide such issue—unless the Secretary General refers the matter to the Court for a decision (Articles 7(1) and 7(2)) where any party:

If the Secretary General refers the case to the Court, the Court will then decide whether and to what extent the arbitration shall proceed. An arbitration will proceed if and to the extent that the Court is prima facie satisfied that an arbitration agreement under the Rules may exist (Article 7(2)).

By agreeing to arbitration under the Rules, the parties agree that the Expedited Procedure Provisions shall take precedence over any contrary terms of the arbitration agreement.

The Expedited Procedure Provisions apply if the amount in dispute does not exceed:

The Expedited Procedure Provisions do not apply if:

The Court may at any time during the arbitral proceedings, on its own motion or upon the request of a party or the arbitral tribunal, and after consultation with them, decide that the Expedited Procedure Provisions shall no longer apply to the case.

For more information on the Expedited Procedure Provisions, see here.

The Highly Expedited Arbitration Provisions can be applied if all parties agree, regardless of the amount in dispute.

During the proceedings, the Highly Expedited Arbitration Provisions will no longer apply if the parties so agree. The Court may also, on its own motion or upon the request of a party or the sole arbitrator, and after consultation with them, decide that the Highly Expedited Arbitration Provisions shall no longer apply to the case.

For more information on the Highly Expedited Arbitration Provisions, see here.

The Emergency Arbitrator Provisions provide a fast-track mechanism for obtaining urgent interim or conservatory measures before the arbitral tribunal is constituted.

A party that needs urgent interim or conservatory measures and cannot await the constitution of an arbitral tribunal may apply for emergency relief. The application can be submitted at the same time, before or after the Request for Arbitration. However, no emergency arbitrator shall be appointed after the file has been transmitted to the arbitral tribunal.

The Emergency Arbitrator Provisions do not apply if:

Furthermore, the Emergency Arbitrator Provisions apply only to parties that are signatories to the arbitration agreement that is relied upon for the application, successors to such signatories, or any party for whom the President is satisfied that an arbitration agreement binding such party may exist.

For more information on Emergency Arbitrator Provisions, see here.

After receipt of the Request, the Secretary General normally requests the Claimant to pay a provisional advance intended to cover the costs of arbitration until the initial Case Management Conference.

The Claimant’s payment is then credited towards its share of the advance on costs. Typically, the Court and Secretariat will not take any steps in the arbitration, such as towards constituting the arbitral tribunal, until the provisional advance has been paid.

The Rules allow any party to an arbitration to join any other party, prior to the appointment or confirmation of any arbitrator. Requests for Joinder of a party are similar to Requests for Arbitration (Article 8).

When a Request for Joinder is submitted before the confirmation or appointment of an arbitrator, the additional party becomes a party to the arbitration and may raise pleas pursuant to Article 7(1) of the Rules. It is important to be aware of the timing for such joinder, as no additional party may be joined after the confirmation or appointment of an arbitrator—unless (i) the additional party accepts the constitution of the arbitral tribunal, and (ii) the arbitral tribunal, once constituted, decides to accept the Request for Joinder.

Constitution of the Arbitral Tribunal and Fixing the Advance on Costs

Following receipt of the Answer(s) to the Request (or the expiration of the time limit for its receipt), and the Answer(s) filed by any additional parties joined under Article 8, the Secretary General and/or the Court may need to take certain decisions to constitute the arbitral tribunal.

For example, the Rules require that all arbitrators nominated by parties be confirmed by the Court or Secretary General (Articles 14(1) and 14(2)).

Furthermore, the Court may be required to appoint the president of the arbitral tribunal, sole arbitrator, or co-arbitrator on behalf of a party that has failed to nominate one (Articles 14(3) and 14(4)). The Court may also need to fix the place of arbitration if the parties have not agreed on a location (Article 19).

In some cases, the Secretary General may decide, under Article 7(1) of the Rules, to refer a prima facie jurisdictional question to the Court. This is necessary to consider whether an arbitration agreement under the Rules may exist and between which parties (Article 7(2)).

Usually, before transmitting the case file to the arbitral tribunal, the Secretary General fixes the advance on costs in an amount likely to cover the fees and expenses of the arbitrators, the ICC administrative expenses, and any other expenses incurred by ICC related to the arbitration. The Secretariat transmits the file to the arbitral tribunal—provided the advance on costs requested at this stage (i.e., the provisional advance) has been paid. Generally, the Secretariat will invite the parties to pay the full advance on costs when it transmits the case file to the arbitral tribunal.

During this early phase of the arbitration, the Secretariat closely monitors the case. While maintaining strict neutrality, it is available to assist the parties with a range of preliminary issues that may come up. Sometimes the resolution of such issues will require input in the form of a decision from the Court. Other times the Secretariat is able to deal with the issue itself.

While maintaining strict neutrality, the Secretariat can always be contacted for any questions concerning the progress of a case. For example, parties may inquire about the status of constituting the arbitral tribunal.

If the parties have not agreed the place of arbitration, the Court will fix it. When agreeing the place of arbitration, the parties should specify the city and country.

Transmission of File and Case Management Conference

The arbitral tribunal is responsible for running proceedings and deciding on the merits of the dispute.

Once the arbitral tribunal has been constituted and the advance on costs requested at this stage has been paid, the Secretariat transmits the file to each member of the arbitral tribunal (Article 17). From that time on, general management of the case shifts from the Secretariat to the arbitral tribunal. Accordingly, the parties should correspond directly with the arbitral tribunal, while sending copies of their correspondence and submissions to the Secretariat and other parties.

Once the file has been transmitted to it, the arbitral tribunal is responsible for running the proceeding and deciding on the merits of a dispute. However, the Court and Secretariat maintain a role. They monitor the arbitral process from start to finish, making sure that cases run smoothly and correctly. They review the progress of each case to ensure it advances at the right speed and in line with the Rules.

Terms of Reference are no longer mandatory for cases administered under the 2026 Rules.

Within 30 days from receiving the file from the Secretariat, the arbitral tribunal is required to hold an initial Case Management Conference and establish a procedural timetable to be followed in the conduct of the arbitration. The Case Management Conference is designed to discuss and put in place the best procedure for the arbitration—particularly in the interests of ensuring time and costs efficiency. Further case management conferences can be held throughout the case as necessary (Article 24(4)).

After the initial Case Management Conference, no party may make new claims unless authorised by the arbitral tribunal.

Arbitral Proceedings

The arbitral tribunal and the parties shall make every effort to conduct the arbitration in an expeditious and cost-effective manner. Please see Part III (Case Management Techniques) of the Note to Parties and Arbitral Tribunals on the Conduct of ICC Arbitration.

If not agreed by the parties, the arbitral tribunal determines the language or languages of the arbitration.

The Rules provide that the arbitral tribunal can order interim or conservatory measures. This does not affect the parties’ rights, in appropriate circumstances, to apply to any competent judicial authority for such measures.

Any party may apply to the arbitral tribunal for the early determination of one or more claims or defences on the grounds that such claims or defences are manifestly without merit, or they are outside the arbitral tribunal’s jurisdiction.

In the absence of an agreement between the parties as to the applicable rules of law, the arbitral tribunal applies the rules of law that it determines to be appropriate. In all cases, the arbitral tribunal takes account of the provisions of the contract and the relevant trade usages.

If the parties have agreed to give it such powers, the arbitral tribunal may act as amiable compositeur or decide ex aequo et bono.

ICC Arbitration procedure is very flexible. The parties and arbitrators are free to fix the rules of procedure, subject to any mandatory provisions that may be applicable. The parties may determine, for instance, whether and to what extent document production requests or cross-examination will be allowed. The arbitral tribunal proceeds within as short a time as possible to establish the facts of the case by all appropriate means. The parties have the right to be heard. The tribunal may also decide to hear witnesses and experts as well as may summon any party to provide additional evidence.

As soon as the last hearing concerning matters to be decided in an award or the filing of the last authorised submissions has occurred, the arbitral tribunal will declare the proceedings closed with respect to the matters to be decided in the award. The arbitral tribunal will also inform the Secretariat and the parties of the date by which it expects to submit its draft award to the Court.

The President of the Court will, at the outset of a case, fix a time limit for the final award or subsequently extend the time limit, based upon the arbitral tribunal’s procedural timetable or the arbitral tribunal’s reasoned request.

Awards and Award Scrutiny

Scrutiny is a distinctive feature of ICC Arbitration. No arbitral award is issued without the Court’s approval.

After the closing of the proceedings, the arbitral tribunal will draw up a draft award that is submitted to the Court for scrutiny. The Court will scrutinise all awards. In doing so, it may lay down modifications as to form and, without affecting the arbitral tribunal’s liberty of decision, draw its attention to points of substance. In scrutinising draft awards, the Court considers, to the extent practicable, the requirements of mandatory law at the place of arbitration.

Once approved by the Court, the award is signed by the arbitrators. It is deemed to be made at the place of the arbitration on the date indicated. It is then notified to the parties by the Secretariat.
