Arbitration procedure provides a structured alternative to court litigation for resolving commercial and international disputes. For businesses entering cross-border contracts, understanding how arbitration proceedings work is essential to managing legal risk, protecting contractual rights and securing enforceable decisions.
Unlike traditional litigation, arbitration generally allows parties greater flexibility in selecting decision-makers, determining procedural rules and choosing the legal seat of their dispute.
However, arbitration is not simply an informal negotiation. It is a legal process governed by an arbitration agreement, applicable national legislation, institutional rules and fundamental principles of procedural fairness.
This guide explains the arbitration procedure step by step, including the commencement of arbitration, appointment of arbitrators, submission of evidence, hearings, arbitral awards and their enforcement. It also examines recent developments in UK arbitration law and international investment dispute resolution.
1. What Is an Arbitration Procedure?
An arbitration procedure is a legally regulated process through which parties submit an existing or future dispute to one or more independent arbitrators instead of asking a national court to determine its merits.
The arbitrator or arbitral tribunal considers the parties’ legal arguments and evidence before issuing a decision, commonly known as an arbitral award.
In most commercial arbitrations, the final award is binding and may be enforced through national courts.
Arbitration is particularly relevant to:
- International commercial contracts and supply agreements
- Construction and infrastructure disputes
- Joint ventures and shareholder disagreements
- International trade and distribution agreements
- Energy and investment disputes
- Cross-border contractual and payment disputes
Example: A UK company enters into a distribution agreement with an overseas supplier. The contract contains an arbitration clause specifying London as the seat of arbitration. If a disagreement arises concerning defective goods or unpaid invoices, either party may be entitled to commence arbitration in accordance with that clause.
The precise procedure depends on the arbitration agreement, the applicable rules and the law of the seat.
2. What Are the Main Stages of the Arbitration Procedure?
Although individual cases vary, the international commercial arbitration procedure generally follows eight principal stages.
Step 1: Establishing the Arbitration Agreement
The first step is to establish whether the parties have agreed to resolve their dispute through arbitration.
An arbitration agreement may appear as a clause in a commercial contract or as a separate agreement concluded after a dispute arises.
A properly drafted arbitration clause should ordinarily identify:
- The arbitration institution or procedural rules
- The seat of arbitration
- The number of arbitrators
- The language of the proceedings
- The scope of disputes subject to arbitration
Parties should also consider the governing law of the contract and the law applicable specifically to the arbitration agreement. Our guide to arbitration clause drafting explains each of these choices in more detail.
An ambiguous clause can generate preliminary disputes about jurisdiction, applicable rules or the authority of the tribunal.
Step 2: Commencement of Arbitration Proceedings
An arbitration procedure usually begins when the claimant submits a notice or request for arbitration in accordance with the applicable rules.
The initiating document commonly identifies the parties, describes the underlying dispute, refers to the arbitration agreement and sets out the relief requested.
Depending on the rules, filing fees and supporting documentation may also be required.
For example, proceedings administered by the International Chamber of Commerce (ICC) commence through a Request for Arbitration. Under the ICC Arbitration Rules effective from 1 June 2026, the respondent ordinarily has 30 days to submit its Answer after receiving the Request from the Secretariat.
Other arbitral institutions and ad hoc procedures apply different commencement requirements and deadlines.
Practical consideration: Before commencing arbitration, businesses should review contractual notice provisions, limitation periods, jurisdictional requirements and any mandatory pre-arbitration negotiation or mediation steps. An early case assessment brings these points together before costs are incurred.
Step 3: Appointment of the Arbitral Tribunal
Once arbitration has commenced, the arbitral tribunal must be constituted.
Depending on the agreement and applicable rules, the dispute may be heard by a sole arbitrator or a tribunal consisting of three or more arbitrators.
In a typical three-member tribunal, each party may nominate an arbitrator, with the presiding arbitrator selected through an agreed or institutional procedure.
However, nomination is not necessarily equivalent to formal appointment. Some arbitration institutions retain exclusive authority to appoint or confirm arbitrators.
Arbitrators must comply with applicable requirements concerning independence and impartiality. See our page on arbitrator appointments for how conflict checks and disclosure work.
Example: Two companies disagree over a multimillion-pound construction project. Their agreement provides for three arbitrators. Each company nominates a candidate, while the presiding arbitrator is selected according to the agreed institutional rules.
The composition of the tribunal can materially influence the efficient management of technically complex disputes.
Step 4: Preliminary Meeting and Procedural Timetable
After constitution, the tribunal normally consults the parties to establish a procedural timetable.
This may include deadlines for written submissions, document production, witness statements, expert evidence and hearings.
The tribunal may also determine whether proceedings should be conducted remotely, in person or through a combination of both.
Under the ICC Arbitration Rules 2026, a case management conference is used to establish an appropriate procedural framework. The revised rules no longer require Terms of Reference in every ICC case.
Effective procedural management can help reduce unnecessary delay and cost while preserving each party’s opportunity to present its case.
Step 5: Submission of Statements and Documentary Evidence
The written phase of the arbitration procedure generally involves the exchange of legal submissions and supporting evidence.
The claimant presents its case, including relevant contractual obligations, alleged breaches, financial losses and requested remedies.
The respondent then submits its defence and may bring counterclaims.
Supporting evidence may include contracts, invoices, emails, technical reports, witness statements and expert opinions.
Unlike litigation in certain national courts, international arbitration does not necessarily involve broad disclosure of every potentially relevant document. Document production depends on the agreed procedure, applicable rules and tribunal orders.
Example: In a dispute concerning delayed delivery of industrial equipment, relevant evidence might include the supply agreement, delivery schedules, correspondence, inspection reports and financial records demonstrating alleged losses.
The quality and organisation of documentary evidence can significantly affect the tribunal’s assessment of the dispute.
Step 6: Arbitration Hearing
A hearing provides the parties with an opportunity to present oral arguments and, where appropriate, examine witnesses and experts.
Not every arbitration requires an oral hearing. Depending on the applicable legal framework, party agreements and tribunal directions, some disputes may be determined on written submissions alone.
Where a hearing takes place, it may involve opening statements, factual witness testimony, expert evidence and closing submissions.
The tribunal must ensure compliance with applicable procedural fairness obligations, including giving parties a reasonable opportunity to present their cases.
Step 7: The Arbitral Award
After considering the evidence and legal submissions, the tribunal issues its arbitral award.
Depending on the nature of the dispute, the award may address liability, damages, contractual performance, interest and allocation of costs.
The applicable rules and law determine formal requirements, including whether reasons must be provided, how the award must be signed and how it is communicated to the parties.
In ICC arbitration, the institution scrutinises draft awards before they are issued, without replacing the tribunal’s decision on the merits.
An award may be subject to limited correction, interpretation, challenge or other post-award procedures. The available remedies depend on the applicable arbitration regime.
Step 8: Recognition and Enforcement of the Arbitration Award
Obtaining a favourable arbitral award does not always mean that the unsuccessful party will comply voluntarily.
If the losing party refuses to perform its obligations, the successful party may need to seek recognition and enforcement before a competent national court.
One of the central instruments governing international enforcement is the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards.
The Convention establishes a framework for recognising arbitration agreements and enforcing foreign arbitral awards among contracting states, subject to specified grounds for refusal.
These grounds include certain problems concerning the validity of the arbitration agreement, procedural fairness, the tribunal’s authority, arbitrability and public policy.
The Convention does not guarantee automatic enforcement in every case. Local procedural requirements and relevant Convention provisions must still be satisfied. Our guide to the enforcement of arbitral awards covers the UK, the UAE and Iran.
3. Institutional Arbitration and Ad Hoc Arbitration
Businesses choosing an arbitration procedure should understand the difference between institutional arbitration and ad hoc arbitration.
Institutional arbitration is administered by an organisation such as:
- International Chamber of Commerce (ICC)
- London Court of International Arbitration (LCIA)
- Singapore International Arbitration Centre (SIAC)
The institution provides administrative assistance and procedural rules, although the precise scope of supervision differs between institutions. For a comparison, see choosing an international arbitration institution.
Ad hoc arbitration proceeds without a permanent institution administering the case. The parties and tribunal arrange the proceedings, frequently using established rules such as the UNCITRAL Arbitration Rules.
Both models can be effective. The appropriate choice depends on the complexity of the dispute, contractual arrangements, administrative requirements and potential enforcement considerations.
4. Arbitration Procedure Under UK Law
The legal framework for arbitration seated in England, Wales or Northern Ireland is principally contained in the Arbitration Act 1996, as amended by the Arbitration Act 2025.
The 2025 amendments came into force principally on 1 August 2025 and introduced important changes concerning arbitration agreements and tribunal powers.
One significant change is the statutory rule governing the law applicable to an arbitration agreement.
Under the new section 6A of the Arbitration Act 1996, the law governing an arbitration agreement is the law expressly chosen for that agreement or, in the absence of such a choice, the law of the seat of arbitration, subject to the provision’s scope and transitional rules.
A choice of governing law for the main contract does not, by itself, amount to an express choice of law for the arbitration agreement.
This distinction can be particularly important in international contracts where the governing law of the commercial relationship differs from the seat of arbitration.
Businesses drafting or reviewing arbitration clauses should therefore consider the interaction between contractual governing law, arbitral seat and the legal framework governing the arbitration agreement.
5. International Investment Arbitration Procedure
International investment arbitration is different from ordinary commercial arbitration.
Commercial arbitration typically concerns disputes arising from private contractual relationships. Investment arbitration may involve claims brought by foreign investors against host states under investment treaties, legislation or investment agreements.
These disputes can raise questions concerning state sovereignty, investor protection, public regulation and access to justice.
The Debate Over Investment Arbitration Reform
In his 2026 article, Investment Dispute Settlement Reform in Africa: A Proposal for an AfCFTA Investment-Related Dispute Settlement System, published in Arbitration International by Oxford University Press, Akinwumi Ogunranti examines the institutional design of investment dispute resolution in Africa.
The research considers whether investors should be required to exhaust remedies before national courts prior to pursuing international investor-state arbitration.
It identifies difficulties that can arise when domestic judicial institutions lack independence, adequate resources or effective mechanisms for resolving complex investment disputes.
The article argues that institutional design should be assessed against three interconnected objectives:
- Fairness: Providing impartial procedures and effective access to justice.
- Efficiency: Reducing unnecessary delay, procedural cost and institutional uncertainty.
- Peace: Supporting legal dispute resolution rather than political confrontation.
Ogunranti proposes an African Continental Free Trade Area investment-related dispute settlement system incorporating a panel and appellate structure.
This is an academic reform proposal rather than a description of an already established general investment arbitration procedure.
The research illustrates why arbitration procedure is not merely a technical issue. The institutional framework can affect the legitimacy, independence and effectiveness of international dispute resolution.

6. How Long Does the Arbitration Procedure Take?
There is no universal duration for arbitration proceedings.
The timetable depends on factors such as the number of parties, complexity of the dispute, availability of evidence, procedural applications and the applicable institutional rules.
Some institutions offer expedited or highly expedited procedures for qualifying disputes, while complex international cases may involve extensive submissions and multiple hearings.
Businesses should not assume that arbitration is always faster than litigation.
A well-drafted arbitration agreement, realistic procedural timetable and effective case management can improve efficiency.
7. What Are the Costs of Arbitration?
The overall cost of arbitration may include:
- Arbitrator fees
- Institutional administrative charges
- Legal representation and advisory costs
- Expert witness and translation expenses
- Hearing facilities and technology
- Expenses associated with obtaining and presenting evidence
Depending on the applicable rules, the tribunal may allocate some or all arbitration costs between the parties.
Arbitration can be cost-effective in appropriate circumstances, but highly complex international disputes can be expensive.
8. Advantages and Limitations of Arbitration Proceedings
Potential Advantages
Arbitration may provide flexibility in procedural design, opportunities to appoint specialist decision-makers and a recognised framework for cross-border enforcement.
Parties may also be able to select a neutral seat and avoid litigating the merits of a dispute in the courts of the other contracting party’s country.
Potential Limitations
Arbitration can involve significant costs, restricted appeal opportunities and procedural complications involving multiple contracts or parties.
Confidentiality should not be assumed in every case. Its scope depends on the governing law, applicable rules, party agreements and circumstances of the dispute.
Likewise, the enforceability of an award must be assessed in relation to the jurisdiction where enforcement is sought and the assets available there.
9. Common Mistakes in International Arbitration
Businesses can reduce legal and commercial risks by avoiding several common mistakes.
Poorly drafted arbitration clauses: Unclear provisions may lead to disputes concerning jurisdiction, the seat or the applicable procedural rules.
Failure to preserve evidence: Missing documents or incomplete records can weaken an otherwise legitimate claim.
Ignoring procedural deadlines: Failure to submit required documents or respond to procedural orders may have serious consequences.
Overlooking enforcement requirements: A successful award may have limited practical value if the opposing party has no identifiable assets in a jurisdiction where enforcement is realistically available.
Confusing commercial and investment arbitration: These procedures can arise from different sources of jurisdiction and have substantially different legal frameworks.
Early assessment of these issues can help businesses make informed decisions before commencing arbitration.

Frequently Asked Questions About Arbitration Procedure
What is the first step in the arbitration procedure?
The first step is generally to confirm that a valid arbitration agreement exists and identify the governing procedural rules. The claimant can then commence proceedings through the prescribed notice or request.
Is arbitration legally binding?
In most commercial arbitration proceedings, a final arbitral award is binding on the parties, subject to the applicable legal framework and limited rights of challenge or other review.
Can arbitration take place without a court hearing?
Yes. Arbitration generally takes place outside ordinary court litigation, although courts may have supervisory and enforcement functions. The arbitration itself may involve an oral hearing or, in appropriate circumstances, a documents-only procedure.
Can an arbitration award be enforced internationally?
Foreign commercial arbitral awards can often be recognised and enforced under the New York Convention, subject to its requirements and the domestic law of the enforcing jurisdiction. Awards under specialised investment arbitration regimes may be governed by different enforcement provisions.
What is the difference between arbitration and mediation?
An arbitrator ordinarily determines the dispute through a binding award. A mediator facilitates negotiations but does not normally impose a binding determination on the parties. See our page on mediation and settlement.
Is arbitration confidential?
Not necessarily. Confidentiality depends on the arbitration agreement, institutional rules, applicable law and the nature of the proceedings.
Can a party refuse to participate in arbitration?
A party may refuse to participate, but non-participation does not necessarily prevent the proceedings from continuing. The tribunal must still satisfy applicable jurisdictional and procedural fairness requirements.
Conclusion
Understanding the arbitration procedure is essential for businesses involved in international trade, investment and cross-border contractual relationships.
From drafting an effective arbitration agreement to managing evidence, obtaining an arbitral award and pursuing enforcement, every stage requires careful attention to the governing legal framework.
The continuing evolution of arbitration law, institutional rules and investment dispute settlement mechanisms makes accurate procedural planning increasingly important.
For businesses dealing with Iranian legal issues or cross-border commercial matters, specialist legal research and appropriately coordinated advice can help identify jurisdictional risks and support informed dispute resolution strategies.
