Construction Arbitration in Uganda (2026): Draft Clauses, Interim Relief, Mediation Windows & Enforcement

Last reviewed: 17 May 2026

Construction arbitration in Uganda has entered a new era. Two landmark instruments, the Arbitration & Conciliation (Amendment) Act 2024 and the Judicature (Court Annexed Mediation) Rules 2026 (SI No. 14 of 27 March 2026), have reshaped how construction disputes are initiated, mediated, decided and enforced. The 2024 Amendment narrows appeal grounds and restricts court intervention, giving arbitral awards significantly greater finality. Meanwhile, the 2026 Rules introduce mandatory court-annexed mediation tracks, formal mediator accreditation requirements and regulated mediation timelines that directly affect when and how parties can escalate to arbitration. For contractors, project owners and counsel managing infrastructure projects across Uganda, these changes demand immediate attention to clause drafting, interim-relief strategy and post-award enforcement planning.

Executive Summary, What the 2024–2026 Reforms Mean for Construction Disputes in Uganda

The combined effect of the Arbitration & Conciliation (Amendment) Act 2024 and the Judicature (Court Annexed Mediation) Rules 2026 is a construction dispute resolution Uganda framework that favours speed, specialist decision-making and early settlement. Courts will intervene less frequently, appeal avenues have been curtailed, and parties who fail to engage with mediation requirements risk procedural sanctions or unenforceability of their preferred dispute-resolution pathway.

Industry observers expect these reforms to accelerate the broader shift towards alternative dispute resolution (ADR) in Uganda’s construction sector, a trend already well documented in practice. The likely practical effect will be to reward parties who plan their dispute-resolution clauses carefully and penalise those who rely on outdated standard-form language.

Top 5 action items for contracts and disputes:

• Audit existing arbitration clauses. Review every live construction contract for compliance with the 2024 Amendment and the 2026 mediation rules.
• Insert mediation-window language. Ensure clauses accommodate regulated mediation timelines without surrendering urgent interim-relief rights.
• Verify mediator accreditation. Confirm that any nominated mediator meets the accreditation standards set out in the 2026 Rules.
• Reassess appeal and enforcement strategy. Factor in the narrowed appeal grounds when deciding whether to pursue security for costs or partial awards.
• Preserve evidence early. With tighter court oversight, document preservation and timely contractual notices are more important than ever.

Timeline, Legislative and Rules Roadmap

Understanding the sequencing of Uganda’s arbitration rules reforms is essential for determining which regime applies to a given dispute. The table below maps the key instruments and their practical consequences for construction dispute resolution in Uganda.

Parties should treat 27 March 2026 as the critical compliance date for mediation-related obligations. For arbitration appeals and enforcement, the 2024 Amendment applies to proceedings commenced after its commencement date.

What Changed in the Uganda Arbitration Rules 2026 and Judicature Mediation Rules 2026

The Judicature (Court Annexed Mediation) Rules 2026 represent the most significant overhaul of Uganda’s mediation rules in over a decade. They establish a structured, court-supervised mediation process that intersects directly with construction arbitration practice.

Key changes include regulated mediation windows that set defined timelines for mediation completion, formal mediator accreditation standards with a code of conduct, and a structured referral mechanism through which courts can direct parties to mediation before or alongside arbitral proceedings. For construction disputes, where multi-party claims, technical complexity and high values are the norm, these changes add both opportunity and procedural risk.

Mediator Accreditation, Requirements and Implications

The 2026 Rules introduce formal accreditation criteria for mediators operating within the court-annexed framework. Under the Rules, mediators must satisfy training, experience and ethical requirements set out in the accompanying schedules, including adherence to a code of conduct for mediators.

• Accreditation verification is now a compliance step. Parties nominating mediators should confirm accreditation status before appointment to avoid challenges.
• Code of conduct obligations. Accredited mediators are bound by disclosure, impartiality and confidentiality requirements, breaches may affect the validity of mediated settlements.
• Private mediators. Parties can still nominate private mediators outside the court-annexed scheme, but industry observers expect that courts will increasingly scrutinise whether those mediators meet equivalent standards.

Understanding mediator accreditation in Uganda is now essential for any party drafting or invoking a mediation clause in a construction contract.

Mediation Windows, Timing and Tolling of Limitation Periods

The 2026 Rules introduce defined mediation timelines, commonly referred to as mediation windows, within which parties are expected to attempt settlement before proceeding to arbitration or trial. Where a court refers a matter to mediation, the Rules set specific periods for completion.

• Practical effect on construction disputes. Contractors and owners must factor mediation windows into project dispute timelines, particularly for time-sensitive claims such as extension-of-time disputes or interim payment applications.
• Tolling and limitation. Early indications suggest that limitation periods are tolled during court-annexed mediation, but parties should document the commencement and conclusion of mediation windows carefully to preserve their rights.
• Interaction with arbitration clauses. Where a contract contains a multi-tier dispute clause (negotiation → mediation → arbitration), the 2026 Rules may impose additional mediation steps even where the contractual mediation has already been attempted.

The Arbitration & Conciliation (Amendment) Act 2024, Appeals and Enforceability

The Arbitration & Conciliation (Amendment) Act 2024 marks a deliberate legislative shift towards greater finality for arbitral awards in Uganda. The Amendment narrows the grounds on which parties can appeal arbitral awards and restricts the scope of court intervention during arbitral proceedings. For construction arbitration in Uganda, where large sums and long project timelines amplify the cost of post-award challenges, this reform is transformative.

The 2024 Amendment tightens the circumstances in which courts may set aside awards, aligning Uganda more closely with international best practice under the UNCITRAL Model Law. Arbitration appeals in Uganda are now confined to significantly narrower grounds, and the Court of Appeal has begun applying these restrictions in early 2026 decisions.

Practical Effect for Construction Awards

• Greater finality. Partial awards, interim awards on costs, and final awards are all less vulnerable to appellate challenge, encouraging parties to seek early interim or partial relief within the arbitration itself.
• Security for costs. With fewer appellate options, respondents may seek security for costs more aggressively at the outset of arbitration, anticipating that awards will be enforced more swiftly.
• Time savings. The likely practical effect will be to reduce the post-award enforcement timeline from years to months in straightforward cases, a significant change for project cash-flow management.

Recommended Clauses to Reduce Risk of Post-Award Challenges

• Expressly waive appeal rights to the maximum extent permissible under the 2024 Amendment.
• Include a clause requiring the losing party to comply with the award pending any application to set aside.
• Specify that any application to set aside must be filed within the statutory time limit and that failure to do so constitutes a waiver.
• Consider including a costs-follow-the-event clause to discourage frivolous post-award applications.

Interim Relief in Construction Arbitration, Courts vs Emergency Arbitrators

Interim relief remains one of the most tactically important tools in construction disputes. The interaction between the 2024 Amendment, the 2026 mediation rules, and the inherent jurisdiction of Ugandan courts creates a layered framework that requires careful navigation. Parties need to understand when to apply to court, when to invoke emergency arbitrator provisions, and how mediation windows affect both pathways.

Under the Arbitration & Conciliation Act (as amended in 2024), courts retain jurisdiction to grant interim measures in support of arbitration, including preservation orders, injunctions and freezing orders. However, the 2024 Amendment’s emphasis on reduced court intervention means that applications must be carefully framed to demonstrate that the relief is genuinely urgent and that the tribunal is not yet constituted or is unable to act effectively.

Can Parties Still Obtain Interim Relief During Mediation Windows?

Yes. Courts retain the power to grant urgent interim relief even while a matter is subject to a mediation window under the 2026 Rules. However, parties should expect heightened judicial scrutiny of urgency and irreparable harm, particularly where the court has already referred the matter to mediation.

Process map for obtaining interim relief during a mediation window:

1. Assess urgency. Confirm that the relief sought cannot wait until mediation concludes, typical construction examples include asset dissipation, destruction of project records, or ongoing defective works.
2. Prepare supporting evidence. File an affidavit demonstrating irreparable harm if relief is not granted immediately.
3. File application in the High Court. Apply under the relevant provisions of the Arbitration & Conciliation Act for interim measures in support of arbitration.
4. Notify the mediator and opposing party. Provide written notice that an interim-relief application has been filed, failure to do so may be treated as a breach of the mediation protocol.
5. Obtain the order and return to mediation. If relief is granted, the mediation window continues, the court order preserves the status quo while settlement is pursued.

Urgent Affidavit Checklist for Interim Relief Applications

• Identity of parties and arbitration reference. Full names, contract details, and (if applicable) the mediation reference number.
• Nature of the dispute. Brief summary of the underlying construction claim.
• Relief sought. Specific interim measures requested (preservation, injunction, freezing order, security).
• Urgency and irreparable harm. Detailed evidence of why the matter cannot await the outcome of mediation or tribunal constitution.
• Steps already taken. Evidence that mediation has commenced or that the party has engaged with the mediation-window requirements.
• Undertaking as to damages. Standard undertaking to compensate the respondent if interim relief is subsequently found to have been unwarranted.
• Draft order. Proposed form of order for the court’s consideration.

Drafting Construction Arbitration Clauses in Uganda, Model Clause and Annotated Notes

How should construction arbitration clauses be drafted now to protect enforceability and interim-relief rights? The answer requires balancing the 2024 Amendment’s emphasis on finality with the 2026 Rules’ mediation requirements and the practical realities of construction disputes. Below is a model clause tailored to the current framework, followed by annotated drafting notes.

Model Construction Arbitration Clause (Uganda, 2026 compliant):

“1. Any dispute arising out of or in connection with this Contract, including any question regarding its existence, validity or termination, shall be resolved in accordance with the following procedure:

(a) Negotiation. The parties shall first attempt to resolve the dispute through good-faith negotiation within fourteen (14) days of written notice of the dispute.

(b) Mediation. If the dispute is not resolved by negotiation, the parties shall submit the dispute to mediation administered by an accredited mediator in accordance with the Judicature (Court Annexed Mediation) Rules 2026 or such other accredited mediation provider as the parties may agree. The mediation shall be completed within sixty (60) days of referral unless the parties agree in writing to extend this period.

(c) Arbitration. If the dispute is not resolved by mediation, or if either party determines that the dispute requires urgent interim relief that cannot await mediation, the dispute shall be referred to and finally resolved by arbitration under the Arbitration & Conciliation Act (Cap. 4, as amended in 2024). The seat of arbitration shall be Kampala, Uganda. The tribunal shall consist of [one/three] arbitrator(s). The language of the arbitration shall be English.

(d) Interim relief. Nothing in this clause shall prevent either party from applying to the High Court of Uganda or to an emergency arbitrator for urgent interim or conservatory measures at any time, including during any mediation window.

(e) Consolidation and joinder. The tribunal may, on the application of any party, consolidate related arbitrations or join additional parties where the claims arise out of or in connection with the same project or series of contracts.

(f) Fast-track option. Where the amount in dispute does not exceed [UGX amount / USD equivalent], the dispute shall be resolved under fast-track procedures with a sole arbitrator, abbreviated timelines and a hearing on documents only unless the tribunal directs otherwise.

(g) Waiver of appeal. To the maximum extent permitted by the Arbitration & Conciliation Act (as amended in 2024), the parties waive any right of appeal against the award.”

Annotated Drafting Notes

• Mediation window (clause 1(b)). The sixty-day mediation period aligns with typical court-annexed timelines and satisfies the 2026 Rules’ expectations without unreasonably delaying access to arbitration. Parties may adjust this period for high-value or technically complex disputes.
• Accredited mediator requirement. Referencing accreditation under the 2026 Rules ensures the mediation will withstand procedural challenge, a critical consideration for enforceability of any mediated settlement.
• Interim-relief carve-out (clause 1(d)). This preserves access to court even during mediation, addressing a key concern under the 2026 framework. Without this language, a respondent could argue that the mediation window bars court applications.
• Waiver of appeal (clause 1(g)). The 2024 Amendment already narrows appeal grounds, but an express waiver reinforces finality and discourages tactical delay.
• Consolidation (clause 1(e)). Construction projects frequently involve subcontractors, consultants and funders. Consolidation language prevents parallel proceedings and inconsistent awards.
• Seat. Specifying Kampala as the seat ensures that Ugandan law governs the arbitration procedure, that the 2024 Amendment applies, and that enforcement follows the domestic regime.

Enforcement and Practical Steps Post-Award, Domestic and Cross-Border

Arbitration enforcement in Uganda has become more predictable under the 2024 Amendment, but practitioners must still navigate specific procedural requirements. The enforcement framework operates through the Arbitration & Conciliation Act, which allows a party to apply to the High Court for recognition and enforcement of an arbitral award as if it were a court decree.

Domestic enforcement checklist:

1. Obtain the original award or a certified copy, together with the original arbitration agreement.
2. File an application in the High Court for leave to enforce the award.
3. Serve the application on the respondent with notice of the right to oppose.
4. If the respondent opposes, the court will hear the application, but note that the 2024 Amendment confines the grounds of opposition to those permissible for setting aside.
5. Once leave is granted, the award is enforceable as a court decree, execution follows the standard civil procedure rules.

Enforcement Against State Entities and Public Projects

Construction disputes in Uganda frequently involve government entities, statutory authorities or public-private partnership vehicles. Enforcement against state entities raises additional considerations:

• Sovereign immunity. Confirm whether the state entity has waived immunity in the arbitration agreement or the underlying contract.
• Budget and appropriation constraints. Even with a valid award, payment from government entities may depend on budget allocation, practitioners should consider including contractual provisions for dedicated escrow or project accounts.
• Attorney General notification. Where the Government of Uganda is a party, the Attorney General must typically be served and given the opportunity to be heard.

Recommendations for Preserving Enforceability in International Contracts

• Ensure the arbitration clause specifies a seat in a New York Convention signatory state (Uganda acceded to the Convention).
• Use institutional arbitration rules where cross-border enforcement is anticipated, institutional awards tend to face fewer procedural challenges.
• Avoid hybrid or pathological clauses that mix litigation and arbitration, as these may provide grounds for resisting enforcement.
• Document compliance with all procedural requirements, including mediation prerequisites, to prevent a respondent from arguing that the award is premature or procedurally defective.

When to Mediate vs Arbitrate Under the 2026 Rules, Decision Flow for Parties

The mediation rules in Uganda now create a structured pathway that parties must navigate before, or in parallel with, arbitration. The decision of whether to mediate, arbitrate or pursue both simultaneously depends on several practical factors.

Decision flow, If/Then checklist:

• If the contract contains a multi-tier clause → follow the contractual steps (negotiation, mediation, arbitration) in sequence. Skipping mediation may expose the claiming party to a jurisdictional objection.
• If the dispute requires urgent interim relief → apply to court or an emergency arbitrator immediately, regardless of mediation status. The interim-relief carve-out in your clause (see model clause above) preserves this right.
• If the court has referred the matter to mediation → engage with the court-annexed process within the prescribed timelines. Failure to participate in good faith may result in adverse costs orders.
• If the dispute involves purely technical valuation issues → mediation may be efficient where both parties have access to agreed expert reports. Consider agreeing to a compressed mediation window.
• If the claim exceeds a defined threshold or involves multiple parties → arbitration is likely more appropriate from the outset, though mediation may still be required as a preliminary step under the 2026 Rules.
• If the respondent is a state entity → assess sovereign immunity, budget constraints and political considerations before selecting the dispute-resolution pathway. Mediation may achieve faster results where government willingness to settle exists.

The key principle is that mediation and arbitration are no longer alternative tracks, under the 2026 Rules, they are often sequential stages in a single dispute-resolution pathway. Drafting should reflect this reality.

Next Steps

The 2024–2026 reforms make construction arbitration in Uganda more efficient but also more demanding from a compliance and drafting perspective. Contractors, project owners and counsel should take the following steps now:

• Review all live construction contracts for compliance with the 2024 Amendment and the 2026 mediation rules.
• Update standard-form arbitration clauses to incorporate mediation windows, accredited-mediator references, interim-relief carve-outs and appeal waivers.
• Engage specialist arbitration counsel for active disputes to ensure procedural steps comply with the new framework and preserve enforcement rights.
• Monitor judicial developments as Ugandan courts continue to interpret the 2024 Amendment and 2026 Rules in the months ahead.
