If you are a project owner facing a payment withholding, a contractor chasing an unpaid interim certificate, or in-house counsel drafting the dispute clause for a new Kenyan construction contract, the question of adjudication vs arbitration vs litigation for Kenya construction disputes has never been more consequential. Kenya’s dispute-resolution landscape is shifting: the Government’s Sessional Paper No. 4 of 2024 (National ADR Policy) laid the groundwork for three draft bills published for consultation in 2025, a Construction Payments Adjudication Bill, an Arbitration (Amendment) Bill, and a Dispute Resolution Bill, each of which proposes features that change the cost, speed, and enforceability calculus for construction claims. This guide gives you a practical, side-by-side decision framework, grounded in the Arbitration Act (Cap.
49), the proposed legislation, and current institutional practice at the Nairobi Centre for International Arbitration (NCIA), so you can choose the right forum before you engage counsel.
Not every construction dispute demands the same forum. The choice between adjudication, arbitration and litigation turns on what you need right now and what you need ultimately. Four fact patterns dominate Kenyan construction disputes:
Each scenario points towards a different forum, or a sequenced combination. The sections below explain each option, compare them dimension by dimension, and end with a clear “choose when” framework.
Adjudication is a rapid, interim dispute-resolution process in which a neutral adjudicator renders a temporarily binding decision, typically on payment or valuation disputes, within a compressed timetable. In Kenya, adjudication has historically been a creature of contract: parties opt in through clauses in FIDIC, JBC, or bespoke agreements. The draft Construction Payments Adjudication Bill (2025) proposes to put adjudication on a statutory footing for the first time, creating mandatory payment schedules and enforcement certificates modelled on the “pay now, argue later” approach used in the United Kingdom, Singapore, and Australia.
Academic commentary in the Strathmore Law Review has noted the constitutional and practical questions surrounding the temporary-finality model, but industry observers expect the statutory framework, once enacted, to be transformative for cash-flow management on Kenyan projects.
Adjudication is designed for disputes that arise during the life of a project and require an answer within days, not months. Under the draft Bill, an adjudicator would be required to decide within 14 days of referral (extendable with party consent), and the losing party would be obliged to comply with the decision pending any later arbitration or litigation. In practice, adjudication is triggered when:
Adjudication is the route of choice for contractors and subcontractors who need cash flow restored quickly, before the project stalls. It also suits employers who want early certainty on a valuation dispute without the expense of full arbitration. Project financiers benefit because adjudication keeps works moving, protecting security over the asset under construction. It is less suitable for complex, document-heavy disputes where finality matters more than speed.
Arbitration in Kenya is governed by the Arbitration Act (Cap. 49), which is based on the UNCITRAL Model Law. Parties may choose institutional arbitration, administered by the Nairobi Centre for International Arbitration (NCIA) under the NCIA Arbitration Rules (2019), or by international institutions such as the ICC or LCIA, or ad hoc arbitration under bespoke or UNCITRAL rules. Kenya is a signatory to the New York Convention (1958), meaning Kenyan arbitral awards are enforceable in over 170 contracting states, and foreign awards are enforceable in Kenya.
The Arbitration (Amendment) Bill (2025) proposes to introduce emergency-arbitrator provisions, fast-track procedures, and an Arbitral Court to handle procedural applications, which, if enacted, would materially improve the efficiency and predictability of arbitration for construction disputes.
Arbitration applies when the construction contract contains a valid arbitration agreement. For cross-border projects, international joint ventures, and high-value domestic claims, arbitration is the default forum because of its finality, confidentiality, and international enforceability. Under the Arbitration Act, a Kenyan court presented with a dispute subject to an arbitration agreement is required to stay proceedings and refer the parties to arbitration, unless the agreement is null, void, inoperative, or incapable of being performed. This stay obligation has been upheld consistently by the Kenyan High Court and Court of Appeal.
Arbitration suits parties who need a final and private resolution. International contractors, lenders, and joint-venture partners favour arbitration because the award is enforceable worldwide under the New York Convention. Parties with technically complex disputes (delay analysis, quantum of variations, defects liability) benefit from the ability to appoint specialist arbitrators.
Construction disputes may be filed in the High Court of Kenya, which has unlimited original jurisdiction. The High Court also exercises supervisory jurisdiction over arbitration: it grants stays in favour of arbitration under the Arbitration Act, hears applications to set aside awards, and enforces both domestic and foreign arbitral awards. Where the contract does not contain an arbitration clause, or where the clause is unenforceable, the High Court is the default forum. Courts also retain an essential role in granting interim injunctive relief (including freezing orders) that is beyond the adjudicator’s or arbitrator’s immediate power to enforce.
Litigation suits parties who need the coercive powers of the state, asset-freezing orders, mandatory injunctions, or contempt sanctions. It also suits parties for whom public precedent is strategically important, or where multi-party joinder is easier than in arbitration. Government and parastatal employers sometimes prefer litigation because public-procurement disputes may raise administrative-law questions.
The following table is the centrepiece of this analysis. Use it to compare the three forums across the dimensions that matter most for construction disputes.
| Dimension | Adjudication | Arbitration | Litigation |
|---|---|---|---|
| Best for | Rapid interim decisions, payment and cash-flow disputes on live projects | Final resolution of complex commercial disputes (domestic and international) | Final public resolution; injunctive and constitutional remedies |
| Typical timeline | 14–28 days (draft Bill proposes 14-day decision period, extendable with consent), temporary decision | 6–18 months (fast-track shorter; ordinary track longer) | 12–36+ months (trial through appeal, subject to court backlog) |
| Indicative cost | Low to medium, single adjudicator fee plus limited counsel time | Medium to high, tribunal fees, institutional administration, counsel and expert costs; scales with claim value | Variable, court filing fees are low, but legal fees are high over a multi-year timeline; often comparable to arbitration for complex claims |
| Interim relief | Produces an enforceable payment decision; draft Bill proposes High Court enforcement certificates. Scope narrower than court injunctive powers | Emergency arbitrator available (proposed in Arbitration (Amendment) Bill); interim awards enforceable. Court may also grant interim relief in support of arbitration | Strongest injunctive powers, freezing orders, mandatory injunctions, contempt sanctions |
| Enforceability | Temporarily binding; enforceable as a debt or via summary judgment. Risk: revisable in arbitration or litigation | Final and binding; enforceable domestically under the Arbitration Act and internationally under the New York Convention. Set-aside grounds very limited | Judgments enforceable via court execution. Cross-border enforcement requires reciprocal arrangements or international comity |
| Appeal / review | No formal appeal, decision may be re-opened in arbitration or litigation | Very limited, set-aside under the Arbitration Act on narrow grounds only | Full appeal route: High Court → Court of Appeal → Supreme Court (on constitutional matters) |
| Confidentiality | Generally private if contract so provides | Confidential by agreement or institutional rules | Public record unless court orders otherwise |
| Multi-party joinder | Limited, usually bilateral | Possible under some institutional rules; requires consent or contractual mechanism | Full joinder powers, courts can join third parties |
| Typical users | Contractors and subcontractors needing cash flow; employers wanting quick interim clarity | International parties; parties wanting finality; complex technical disputes | Parties needing public enforcement, urgent injunctions, or judicial precedent |
Cost is often the deciding factor for small and mid-value construction disputes. The table below sets out indicative cost components for adjudication and arbitration. Litigation court fees are comparatively low, but total legal spend over a multi-year proceeding often rivals or exceeds arbitration costs.
| Cost component | Adjudication (indicative) | Arbitration (indicative, NCIA-administered) |
|---|---|---|
| Neutral / tribunal fee | Single adjudicator: scaled to dispute value; proceedings typically completed within weeks | Tribunal fees + NCIA administration fee: scaled to claim value under the NCIA fee schedule; three-arbitrator tribunals cost substantially more |
| Counsel fees (typical hearing) | Limited, typically one to two days of focused written submissions or a single hearing | Multiple hearing days common; extensive written pleadings, witness statements, and legal submissions |
| Expert / technical reports | Usually one report per party; scope is narrow | Multiple experts possible; delay analysis, quantum reports, and site inspections add significant cost |
| Enforcement costs | Court filing for enforcement certificate (if Bill enacted); relatively modest | Domestic enforcement under the Arbitration Act; foreign enforcement under the New York Convention, legal costs for each application |
For a contractor pursuing a payment claim below KES 10 million, adjudication is almost always cheaper and faster than arbitration. For high-value, multi-issue disputes, arbitration’s finality and international enforceability justify the higher cost.
Adjudication is designed to deliver a decision within 14 days of referral (under the draft Bill), making it orders of magnitude faster than arbitration (typically 6–18 months at NCIA) or litigation (12–36+ months in the High Court, longer with appeals). The Kenyan judiciary’s case backlog means that litigation is the slowest route for most construction disputes. The proposed Arbitration (Amendment) Bill’s fast-track procedure, if enacted, may shorten simpler arbitrations to under six months, but this remains to be tested in practice.
This dimension is critical when assets are at risk or a bond call is imminent. The comparison breaks down as follows:
The practical takeaway: if you need to freeze assets or restrain a bond call, go to court, even if the substantive dispute will be resolved in arbitration or adjudication. The Arbitration Act expressly preserves this right.
Enforceability is the dimension where the three forums diverge most sharply:
Each forum carries different strategic risks. Adjudication does not produce a final allocation of liability, it preserves both parties’ rights to a full hearing. Arbitration awards finally allocate liability, including costs, and tribunals can order security for costs where appropriate. Litigation exposes both parties to public scrutiny and full appellate review, which may be strategically valuable (establishing precedent) or harmful (reputational risk). Parties should factor these dynamics into their forum choice at the contract-drafting stage.
Three draft bills, developed under the framework of Sessional Paper No. 4 of 2024 (National ADR Policy), are reshaping the adjudication vs arbitration vs litigation calculus for Kenya construction disputes:
Important caveat: These bills underwent public consultation in 2025 and remain subject to parliamentary process. Readers should verify the current legislative status before relying on any statutory enforcement mechanism described above. If the bills have been enacted, the statutory provisions supersede the contractual framework.
Use the table below to match your priority to the right forum. Then check the scenario examples and immediate-step checklists that follow.
| If your priority is… | Choose… |
|---|---|
| Keeping cash flowing, get an enforceable payment decision within weeks | Adjudication (if contract clause or statutory Bill applies) |
| A final, private, internationally enforceable award | Arbitration (under the Arbitration Act and the New York Convention) |
| Urgent injunctive relief, freeze assets, restrain a bond call, stop works | Litigation (High Court) |
| Low cost, quick resolution of a narrow technical question (interim valuation, extension of time) | Adjudication or a dispute adjudication board |
| Public precedent or constitutional determination | Litigation |
| Cross-border enforcement against assets outside Kenya | Arbitration (New York Convention enforceability) |
| Complex multi-party dispute with joinder requirements | Litigation (full joinder powers) or arbitration with consolidation clause |
Not every construction dispute requires external counsel from day one. But there are specific trigger points where engaging a qualified dispute-resolution lawyer is essential, and where delay can be costly:
A two-hour strategy session with a dispute-resolution specialist, covering forum selection, evidence preservation, cost budgeting, and timetable planning, is the highest-return investment a party can make before committing to a dispute route.

The choice between adjudication, arbitration, and litigation for Kenya construction disputes in 2026 is no longer a binary. Draft legislation is introducing a viable statutory adjudication tier for payment disputes, while proposed arbitration reforms aim to make emergency relief and fast-track procedures more accessible. The right decision depends on what you need: speed and cash flow (adjudication), finality and international enforceability (arbitration), or the coercive power of the court (litigation). In many projects, the optimal approach is a multi-tier clause that sequences adjudication for interim payment disputes, preserves arbitration for final resolution, and carves out court access for injunctive relief.
Whichever route you choose, the time to plan is before the dispute arises, and if the dispute is already live, engage a dispute-resolution specialist today.
