Both are forms of alternative dispute resolution (ADR) that keep a dispute out of the courtroom, but they give the parties very different things. Mediation is a facilitated negotiation: the parties, not the neutral, decide the outcome, and nothing is binding unless they sign a settlement. Arbitration is a private trial: the arbitrator hears evidence and argument and issues a binding award that can be enforced like a judgment. Choosing between them is a decision about control, finality and cost - and where your contract already names one of them, the choice may already have been made for you.
In mediation, a neutral accredited mediator helps the parties identify the real issues, test the strengths and weaknesses of their positions and explore options for settlement. The mediator does not decide the dispute and cannot impose an outcome. The process is confidential and conducted on a without-prejudice basis, and it is non-binding unless the parties sign a settlement agreement - but once signed, that agreement can be recorded and adopted as an order of the court, and it is then enforceable like a decree.
Kenyan courts actively refer civil and commercial disputes to court-annexed mediation before trial. It is quick, inexpensive and preserves commercial relationships, and parties can also choose private mediation at any stage, including before litigation begins.
Mediation tends to suit:
Arbitration is governed by the Arbitration Act, which is closely modelled on the UNCITRAL Model Law. It applies where the parties have agreed in writing to arbitrate - a clause in a contract, or a separate submission agreement signed after the dispute arises. The parties choose the arbitrator or panel, the seat and venue, the language and the procedure, and institutional arbitrations are administered under rules such as those of the NCIA or the Chartered Institute of Arbitrators (Kenya).
If one side ignores the arbitration agreement and sues in court, the court will generally stay the proceedings and refer the parties to arbitration: Kenyan courts uphold arbitration clauses firmly. An award is final and binding, and the grounds for challenging it are narrow - want of jurisdiction, a serious irregularity affecting the fairness of the process, or conflict with public policy. There is no appeal on the merits, and the court will not substitute its own view of the facts.
An award is enforced by applying to the High Court, and it then has the same force as a decree. For international transactions, Kenya's membership of the New York Convention means that Kenyan awards are enforceable in other contracting states and that foreign awards are enforceable in Kenya - a decisive advantage in cross-border contracts.
Arbitration tends to suit:
Mediation is usually the cheapest and fastest route, often concluded in days or weeks, with the cost limited largely to the mediator's fee and each party's own legal costs. Arbitration generally takes months rather than years and is faster than a full trial, but the parties pay the arbitrator's fees - often assessed by reference to the amount in dispute - together with venue, transcription and legal costs. In a smaller claim those costs can exceed the value of the dispute, which is why mediation is usually the better first step. Court-annexed mediation is comparatively cheap because it forms part of the court process.
Confidentiality is another real difference. Arbitration hearings and mediation sessions are private, awards are generally not published, and neither process creates the public record that a court file does. Where sensitive commercial terms, trade secrets, family matters or reputation are involved, both are markedly better than a public trial.
A mediated settlement becomes enforceable when it is recorded and adopted as an order of the court; an arbitral award is enforced through the High Court and has the force of a decree. That matters at the collection stage: an award or consent order against a debtor who refuses to pay is enforced through the same machinery as a judgment - attachment of assets, garnishee orders and, where appropriate, insolvency proceedings. Read our guide on how to recover a debt in Kenya for those enforcement options, and note that enforcing against a foreign party or a foreign asset requires separate steps in that jurisdiction.
A poorly drafted clause can cost more than a bad outcome, because the first fight is about where and how the dispute will be decided. An effective clause:
Our corporate lawyers draft and negotiate dispute resolution clauses before contracts are signed, and our alternative dispute resolution team handles the mediation or arbitration itself.
Before you choose, ask a few practical questions: how important is the relationship after the dispute? Do you need a decision or a deal? How much is at stake compared with the cost of the procedure? Is privacy essential? Where are the assets you may eventually have to enforce against? Will the other side participate voluntarily - and how long can you afford to wait? Our mediation and arbitration lawyers in Nairobi will assess your dispute and recommend the most cost-effective route. Book a consultation today.
