Arbitration in Kenya has become the preferred mechanism for resolving high-value commercial disputes, offering parties a private, binding, and enforceable alternative to litigation in the courts. For businesses operating in Kenya, understanding when arbitration applies, how proceedings are conducted, and how awards are enforced is essential for contract drafting, dispute management, and strategic decision-making.

The Legal Framework for Arbitration in Kenya

Arbitration in Kenya is governed by the Arbitration Act, No. 4 of 1995, as amended by the Arbitration (Amendment) Act, 2009. The Act adopts the UNCITRAL Model Law on International Commercial Arbitration with modifications, providing a modern framework aligned with international best practice. The Nairobi Centre for International Arbitration (NCIA), established under the Nairobi Centre for International Arbitration Act, No. 26 of 2013, administers both domestic and international arbitration proceedings from Kenya.

When Arbitration Applies: The Arbitration Agreement

Arbitration jurisdiction arises from agreement between the parties, not from statute. A valid arbitration agreement, contained in a commercial contract as an arbitration clause or in a separate submission agreement after a dispute has arisen, is the foundation of every arbitration proceeding. Under section 10 of the Arbitration Act, where parties have agreed to refer disputes to arbitration, a court before which an action is brought in breach of that agreement must refer the parties to arbitration on application by either party before or at the time of entering appearance.

An effective arbitration clause specifies the seat of arbitration (typically Nairobi), the arbitral institution and rules (NCIA, ICC, LCIA, or ad hoc), the number of arbitrators (one or three), the language of proceedings, and the law governing the substantive dispute. Poorly drafted arbitration clauses, sometimes called “pathological clauses”, that create ambiguity about the agreed procedure can lead to satellite litigation over jurisdiction before the substantive dispute is even heard.

Arbitration Proceedings in Kenya

An arbitration commences when a party serves a notice of arbitration on the other party in accordance with the agreed rules. For NCIA arbitrations, the request for arbitration is filed with the NCIA, which appoints the tribunal if the parties cannot agree on the arbitrator or if the nominated party fails to cooperate.

Arbitral proceedings in Kenya follow a structured process: filing of statements of claim and defence, document production, witness evidence in written statements, and an oral hearing at which witnesses are examined and submissions are made. The arbitral tribunal controls the procedure and has broad discretion in managing proceedings efficiently. Proceedings are confidential, unlike court hearings, the existence of the arbitration, the evidence presented, and the award are not made public.

Provisional Measures and Interim Relief

Under section 18 of the Arbitration Act, an arbitral tribunal may grant interim measures of protection, including orders to preserve assets, maintain the status quo, or compel production of evidence, pending the outcome of the arbitration. Parties may also apply to the High Court for interim injunctions in support of arbitration proceedings without breaching the arbitration agreement, under section 7 of the Act.

The Arbitral Award

The arbitral tribunal’s decision is set out in a final award, which must be in writing, signed by the arbitrators, and state the reasons for the decision unless the parties have agreed that no reasons need be given. The award is binding on the parties and, in Kenya, is enforced in the same manner as a court judgment under section 36 of the Arbitration Act by filing it in the High Court and obtaining leave to enforce.

Challenging an Arbitral Award

Under section 35 of the Arbitration Act, a party may apply to the High Court to set aside an award only on limited grounds: incapacity of a party, invalidity of the arbitration agreement, denial of the right to present one’s case, the award dealing with matters outside the scope of the submission to arbitration, improper composition of the tribunal, or the award being in conflict with Kenya’s public policy. The grounds for challenge are deliberately narrow to preserve the finality of arbitration and prevent losing parties from re-litigating the merits in court.

For years it was understood that a High Court decision on a section 35 application was itself final, with no further appeal. The Supreme Court narrowed that position in Nyutu Agrovet Limited v Airtel Networks Kenya Limited; Chartered Institute of Arbitrators-Kenya Branch (Interested Party), Petition 12 of 2016, [2019] KESC 11 (KLR), decided 6 December 2019, holding by majority (Chief Justice Maraga dissenting) that a party may, in exceptional circumstances, such as unfairness or misconduct in the High Court’s own decision-making process, appeal that decision to the Court of Appeal. This is a narrow, judge-made exception rather than a general right of appeal, and businesses should not assume a second bite at the merits simply because they disagree with the High Court’s ruling on a setting-aside application.

International Arbitration and the New York Convention

Kenya is a signatory to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards 1958 (New York Convention), meaning that arbitral awards made in other contracting states are enforceable in Kenya and Kenyan awards are enforceable in over 170 countries. This international enforceability makes arbitration the preferred choice for cross-border commercial contracts involving Kenyan parties.

Arbitration versus Litigation: Key Differences for Kenyan Businesses

Arbitration offers several advantages over litigation for commercial disputes in Kenya: confidentiality of proceedings and awards, finality with limited rights of appeal, the ability to select arbitrators with technical expertise relevant to the dispute, and international enforceability of awards. However, arbitration is typically more expensive than litigation in terms of arbitrator fees and administrative costs, and is less suitable for urgent injunctive relief where the court’s coercive power is needed immediately. For lower-value commercial disputes, litigation in the Commercial Court or the magistrates’ courts may be more cost-effective. Where the parties have an ongoing relationship they wish to preserve, or where the dispute is more about miscommunication than a genuine legal question, our guide to mediation in Kenya covers a faster and less adversarial alternative, including how a stepped clause can require mediation before arbitration is triggered.

Drafting Arbitration Clauses in Commercial Contracts

A well-drafted arbitration clause should specify the seat of arbitration, since this determines which national courts have supervisory jurisdiction over the arbitration, the number of arbitrators, the language of the proceedings, and whether the NCIA Rules, the CIArb-Kenya Rules, or another institution’s rules will apply. Parties should also decide whether to name the NCIA or another institution as the appointing authority in case of a dispute over the appointment, since an ambiguous or poorly drafted clause is one of the most common sources of satellite litigation over jurisdiction before the substantive dispute is even reached. Arbitration clauses in joint venture agreements and share purchase agreements arising from mergers and acquisitions should also be checked for consistency with any related mediation or dispute escalation clauses in the same transaction documents, so the parties are not left arguing about which process applies before they can even start resolving the underlying dispute.
