Quick Overview
Commercial arbitration in Kenya is one of the fastest paths to resolving a business dispute without going through the court system. If your contract has a dispute resolution clause, or you are dealing with a counterparty who refuses to perform, your arbitration options right now could save your business months of expensive litigation. This guide covers the full process under the Arbitration Act, Cap. 49, the landmark January 2026 Court of Appeal ruling on award finality, and what the Arbitration (Amendment) Bill 2025 means for businesses operating in Kenya.
What Is Commercial Arbitration in Kenya?
Commercial arbitration in Kenya is a private, binding process for resolving business disputes outside the courts. A neutral third party, the arbitrator, hears both sides and issues an award. That award is enforceable in the same way as a court judgment.
The governing statute is the Arbitration Act, Cap. 49 (originally enacted in 1995, revised in 2012). It is modelled closely on the UNCITRAL Model Law, which means Kenya-seated awards align with international standards and are recognisable across most jurisdictions.
Your business can use commercial arbitration in Kenya when your contract contains an arbitration clause, or when both parties agree to arbitrate after a dispute arises. Courts in Kenya consistently respect and enforce written arbitration agreements.
Practical rule: If you are signing any commercial contract with a counterparty in Kenya or East Africa, include a well-drafted arbitration clause now. Retrofitting it after a dispute arises requires the other party’s consent, which you are unlikely to get when a dispute has already started.
Arbitration vs. Litigation: What Your Business Needs to Know
Litigation and arbitration serve different needs. The right choice depends on your dispute, your contract, and your commercial priorities.
| Factor | Arbitration | Litigation |
|---|---|---|
| Privacy | Proceedings are private | Proceedings are public record |
| Speed | Variable; can be faster with tight timelines | Can take years in Kenya’s courts |
| Cost | Higher upfront (arbitrator fees: USD 150-800/hour) | Lower court fees; costs vary with complexity |
| Expertise | Arbitrator can be a sector specialist | Judges handle all case types |
| Finality | Award is final; very limited grounds to challenge | Multiple appeal levels available |
| Enforceability | Enforceable globally under the New York Convention | Enforceable domestically and by treaty |
Arbitration works best for high-value commercial disputes where confidentiality matters and the parties want a specialist decision-maker. Litigation is appropriate when costs are the primary concern, or the dispute involves a remedy only a court can grant, such as an injunction or a contempt order.
Important context: Kenya’s courts have been consistent in refusing to intervene in arbitration proceedings without strong cause. The January 2026 Court of Appeal ruling has made that position even more pronounced.
From our experience: Most businesses draft arbitration clauses as boilerplate, then discover how important the specific wording is when a dispute actually starts. The dispute resolution clause deserves the same attention as the payment clause.
The Legal Framework for Commercial Arbitration in Kenya
Commercial arbitration in Kenya operates under three layers of authority.
1) The Arbitration Act, Cap. 49. This is the primary statute. It governs the validity of arbitration agreements, appointment of arbitrators, conduct of proceedings, and recognition and enforcement of awards.
2) The Nairobi Centre for International Arbitration Act, No. 26 of 2013. This established the NCIA as a government-backed institution to administer both domestic and international arbitrations. The NCIA published its most recent procedural rules in 2019, which parties can adopt by reference in their arbitration clause.
3) Party agreement. Within the framework of the Act, parties have wide freedom to agree on the number of arbitrators, how they are appointed, the seat of arbitration, the language, and the applicable substantive law.
Important context: If your arbitration clause does not specify institutional rules or a procedure for appointing an arbitrator, disputes about the clause itself may end up before the court before any substantive arbitration begins.
Key 2026 Developments in Commercial Arbitration in Kenya
The landscape for commercial arbitration in Kenya has shifted in the first half of 2026:
- Award finality reinforced (January 2026): The Court of Appeal held in County Government of Kitui v Power Pump Technical Company Limited (Civil Appeal 176 of 2020) that a party cannot challenge an arbitral award through judicial review after failing a Section 35 application.

- Arbitration (Amendment) Bill 2025 before Parliament: The Bill introduces emergency arbitration, third-party funding disclosure requirements, and a new specialist Arbitral Court. It is currently under parliamentary review.

- Nairobi emerging as a regional hub: Kenya is increasingly the preferred seat for East African disputes, supported by an English common law system and improving institutional infrastructure.

- Cost concerns for SMEs persist: Arbitrator fees in Kenya run from USD 150 to USD 800 per hour depending on seniority and dispute complexity. For lower-value disputes, mediation may be a more proportionate first step. [[4]](https://koyaadvocates.co.ke/alternative-dispute-resolution-in-business-disputes-and-arbitration-in-kenya/)
The January 2026 Ruling Every Business With a Commercial Contract Should Know
On 30 January 2026, the Court of Appeal decided County Government of Kitui v Hon. Justice E. Torgbor and Power Pump Technical Company Limited (Civil Appeal 176 of 2020). This ruling is now one of the most important decisions on award finality in recent Kenyan arbitration jurisprudence. [[1]](https://www.cliffedekkerhofmeyr.com/en/news/publications/2026/Kenya/Dispute-Resolution/dispute-resolution-alert-3-march-No-second-bite-at-the-cherry-Court-of-Appeal-bars-judicial-review-of-arbitral-awards-after-failed-section-35-challenge)
The question before the court was direct: can a party that has already failed to set aside an arbitral award under Section 35 of the Arbitration Act seek judicial review of that same award?
The court’s answer was no.
Section 35(2) of the Arbitration Act, Cap. 49 sets out eight grounds on which a party may apply to the High Court to set aside an award. These include: a party to the arbitration agreement was under incapacity; the agreement was invalid; proper notice was not given; the award went beyond the scope of the reference; the tribunal’s composition breached the agreement; or the award conflicts with Kenyan public policy. An application under Section 35 must be filed within three months of receiving the award.
The Court of Appeal found that where a party has invoked this regime and failed, judicial review is not available as a fallback. The Arbitration Act creates a self-contained statutory framework. Repackaging a failed Section 35 challenge as a judicial review application is not permissible.
What this means for your business: If you receive an arbitral award you believe is wrong, your window to challenge it is narrow. File a Section 35 application within three months. Make that application your strongest possible case. After that window closes, the award stands.
Practical rule: When you receive any arbitral award, have a lawyer assess the Section 35 grounds within the first two weeks. The three-month clock is strict, and the January 2026 ruling has removed the judicial review route entirely.
The Arbitration Amendment Bill 2025: What Businesses Need to Know
The Arbitration (Amendment) Bill 2025 is currently before Parliament. Once enacted, it will represent the most significant update to Kenya’s arbitration framework since the original Arbitration Act was passed in 1995. Key provisions of the Bill include the following.
1) Emergency Arbitration. The Bill resolves a longstanding ambiguity by expressly including emergency arbitrator decisions within the definition of “award.” Emergency arbitrator orders will be enforceable in the same way as final awards, provided the parties have consented to emergency arbitration procedures under their chosen institutional rules. [[2]](https://globalarbitrationreview.com/review/the-middle-eastern-and-african-arbitration-review/2026/article/kenya-arbitration-amendment-bill-2025-signals-reset-nairobis-arbitral-ambitions)
2) Third-Party Funding Disclosure. The Bill introduces a new Section 39A to regulate third-party funding in international arbitration seated in Kenya. Funded parties will be required to disclose the existence of the funding arrangement, the identity of the funder, and the nature of the arrangement to the tribunal and the opposing party. This aligns Kenya with standards adopted in Singapore and Hong Kong. [[2]](https://globalarbitrationreview.com/review/the-middle-eastern-and-african-arbitration-review/2026/article/kenya-arbitration-amendment-bill-2025-signals-reset-nairobis-arbitral-ambitions)
3) A Specialist Arbitral Court. The Bill formalises a new Arbitral Court with a dedicated Registrar to handle arbitration-related applications. This channels disputes to judges with arbitration expertise rather than the general commercial division.
4) Summary Determination. The Bill gives tribunals power to summarily dismiss claims or defences that have no real prospect of success, reducing the ability to use arbitration proceedings as a delay tactic.
Important context: The Arbitration (Amendment) Bill 2025 is proposed legislation, not yet in force as at the date of this article. Check its current parliamentary status before relying on any of its provisions. The Arbitration Act, Cap. 49 remains the governing statute.
How Commercial Arbitration in Kenya Works: Step by Step
Understanding the procedural sequence prevents the mistakes that derail valid claims.
Step 1: Check your contract for a dispute resolution clause.
Most commercial contracts contain an arbitration clause specifying whether the process is ad hoc or institutional. Read the clause carefully before taking any other step. The clause will dictate everything that follows.
Step 2: Follow any pre-arbitration steps.
Multi-tier clauses requiring negotiation or mediation before arbitration are common and enforceable in Kenya. Courts will enforce these pre-conditions. If your contract requires 30 days of negotiation before arbitration can begin, you should not skip that step.
Step 3: Issue a notice of arbitration.
The claimant sends written notice to the respondent stating that the dispute is being referred to arbitration, identifying the nature of the dispute, and invoking the arbitration clause. If you are using NCIA Rules, the notice must meet NCIA’s formal requirements.
Step 4: Appoint the arbitrator or tribunal.
The clause will specify the number of arbitrators and the appointment mechanism. A sole arbitrator is common for lower-value disputes. A three-member tribunal is used for complex or high-value matters. Where the parties cannot agree, the court or the NCIA may be asked to make the appointment.
Step 5: Settle the terms of reference.
The tribunal and parties agree on the issues in dispute, the procedure, the timeline, and the venue. This step sets the boundaries of what the tribunal will decide.
Step 6: Exchange statements and evidence.
Each party files its statement of claim or defence, supported by documents and witness statements. Disclosure obligations in arbitration are limited compared to court litigation, which helps manage costs.
Step 7: The hearing.
The tribunal hears witnesses and legal submissions. In simpler cases the tribunal may decide on documents alone, without a hearing.
Step 8: The award.
The tribunal issues a written award. It is binding on both parties. It is enforceable in Kenya under the Arbitration Act, Cap. 49, and internationally under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (Kenya acceded in 1989).
Bottom line: Commercial arbitration in Kenya follows a structured sequence, but every step requires procedural compliance. A procedural failure can delay the proceedings or give the other side grounds to challenge the award under Section 35.
Who Needs Commercial Arbitration Support in Kenya?
Commercial arbitration in Kenya is relevant across a wide range of business types. Here are the situations we see most often.
Contractors and subcontractors: Construction contracts in Kenya frequently require NCIA arbitration. Payment disputes and scope disagreements are the most common triggers.
Foreign investors: Businesses investing in Kenya prefer arbitration because it offers a neutral forum and an internationally enforceable award, rather than a domestic court judgment that may be difficult to recognise abroad.
Financial institutions: Banks and lenders use arbitration clauses in facility agreements to resolve default and enforcement disputes privately and outside the court’s public record.
Technology and fintech companies: Commercial arrangements in this sector move fast. Confidentiality and specialist arbitrators make arbitration the preferred mechanism for contract disputes.
Business partners in shareholder disputes: When a partnership or shareholder relationship breaks down, an arbitration clause in the shareholder agreement provides a structured, private path through the dispute.
Common Mistakes Businesses Make in Commercial Arbitration in Kenya
1) Drafting a vague arbitration clause.
The clause must specify: the number of arbitrators, the method of appointment, the seat of arbitration, the institutional rules (if any), and the governing law. A clause that says only “disputes shall be referred to arbitration” leaves too much undefined and invites a court application before any merits are heard.
2) Missing the Section 35 deadline.
You have three months from receiving the award to apply to set it aside. This is a hard deadline. The January 2026 Court of Appeal ruling closes the judicial review door once that window passes.
3) Ignoring pre-arbitration steps in a multi-tier clause.
If your clause requires 30 days of good faith negotiation before arbitration begins and you skip that step, the respondent can challenge the tribunal’s jurisdiction.
4) Choosing an arbitrator without sector knowledge.
A commercial arbitration in Kenya involving a fintech or construction dispute needs an arbitrator who understands the sector. General legal experience is not enough for specialist matters.
5) Treating arbitration like court litigation.
Arbitration has different disclosure rules, timelines, and procedures. Running it like a court case drives up costs without the procedural protections that court litigation provides.
From our experience: The disputes that produce the worst outcomes are ones where the arbitration clause was drafted without legal input and the procedural framework was left ambiguous. A short review at the contract stage prevents years of procedural uncertainty.

FAQs
What Is Commercial Arbitration in Kenya?
Commercial arbitration in Kenya is a private dispute resolution process in which a neutral arbitrator or tribunal hears and decides a business dispute. It is governed by the Arbitration Act, Cap. 49 and produces a binding award that is enforceable in Kenya and internationally under the New York Convention. It is used as an alternative to court litigation for contract disputes, shareholder disagreements, and other commercial matters.
How Does Commercial Arbitration in Kenya Differ From Mediation?
In arbitration, the arbitrator imposes a binding decision on both parties. In mediation, a neutral facilitator helps the parties reach a voluntary settlement. Neither party can be forced to settle in mediation. Arbitral awards, like court judgments, can be enforced against an unwilling party. Most Kenyan commercial contracts use a multi-tier clause requiring mediation or negotiation before arbitration begins.
What Are the Grounds to Set Aside an Arbitral Award in Kenya?
Section 35(2) of the Arbitration Act, Cap. 49 provides eight grounds: incapacity of a party, invalidity of the arbitration agreement, lack of proper notice, the award going beyond the scope of the reference, improper tribunal composition, conflict with Kenyan public policy, the subject matter not being arbitrable, or the award being procured by fraud, bribery, or undue influence. The application must be filed within three months of receiving the award.
Can a Failed Section 35 Challenge Be Brought Back as a Judicial Review?
No. The Court of Appeal ruled in January 2026 in County Government of Kitui v Power Pump Technical Company Limited that a party that has already failed to set aside an award under Section 35 cannot seek judicial review of the same award. The Arbitration Act, Cap. 49 creates a self-contained regime. Judicial review is not available as a second attempt after the statutory route has failed.
Is Commercial Arbitration in Kenya Confidential?
Yes. Unlike court proceedings, arbitration hearings and awards in Kenya are private. The parties and the tribunal are generally bound to keep the proceedings confidential unless the parties agree otherwise or disclosure is required by law. This confidentiality is one of the primary reasons businesses prefer arbitration for sensitive commercial disputes.
How Long Does Commercial Arbitration in Kenya Typically Take?
The timeline depends on the complexity of the dispute, the efficiency of the arbitrator, and whether the parties comply with procedural directions. Simpler disputes can conclude in six to twelve months. Complex commercial matters may take two to three years. Proceedings under the NCIA Rules include procedural timelines, but compliance depends on both parties.
How Much Does Commercial Arbitration in Kenya Cost?
Arbitrator fees in Kenya range from approximately USD 150 to USD 800 per hour, depending on the arbitrator’s seniority and the nature of the dispute. [[4]](https://koyaadvocates.co.ke/alternative-dispute-resolution-in-business-disputes-and-arbitration-in-kenya/) Institutional fees, venue costs, and legal representation add to the total. For lower-value matters, mediation is often more proportionate.
What Is the NCIA and How Does It Support Commercial Arbitration in Kenya?
The Nairobi Centre for International Arbitration (NCIA) was established by the Nairobi Centre for International Arbitration Act, No. 26 of 2013 as a government-backed institution to administer both domestic and international arbitrations. It provides procedural rules (last revised in 2019), a panel of arbitrators, and administrative support for proceedings. Parties who include NCIA Rules in their arbitration clause give the NCIA a role in administering the process and resolving procedural disputes.
What Does the Arbitration Amendment Bill 2025 Mean for Businesses?
The Arbitration (Amendment) Bill 2025, currently before Parliament, proposes four main changes to commercial arbitration in Kenya: it formalises emergency arbitration and makes emergency orders enforceable; it requires disclosure of third-party funding arrangements; it introduces a specialist Arbitral Court; and it gives tribunals summary determination powers. Once enacted, it will be the first major update to the Arbitration Act since 1995. The existing Act governs until then.
Is a Kenyan Arbitral Award Enforceable Internationally?
Yes. Kenya acceded to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards in 1989. An award issued in a Kenya-seated arbitration is enforceable in over 170 countries that are party to the Convention. For cross-border commercial disputes, this enforceability is a significant practical advantage over a domestic court judgment.
Which Firms Handle Commercial Arbitration in Kenya?
MN Legal handles both domestic and international commercial arbitration in Kenya through its Litigation and Dispute Resolution practice. Mutundu Chege co-heads the team with experience representing commercial banks, manufacturers, and telecoms in high-stakes proceedings.
