How Zambia's ADR Bill 2026 Will Change Commercial Contracts, Practical Guidance for Drafting Arbitration & Mediation Clauses

The Zambia ADR Bill, formally handed to Government in February 2026 during Lusaka Arbitration Week, represents the most significant overhaul of alternative dispute resolution legislation in Zambia in decades. Developed by the Zambia Law Development Commission (ZLDC) and aligned with the UNCITRAL Model Law on International Commercial Arbitration, the Draft ADR Bill 2026 introduces a unified statutory framework for arbitration, mediation, and the enforcement of mediated settlement agreements. For in-house counsel, contract managers, and business owners with commercial contracts governed by Zambian law, the practical implication is immediate: existing arbitration and mediation clauses must be reviewed, redlined, and updated to reflect the procedural changes the Bill will bring upon enactment.

Executive Summary: What the Zambia ADR Bill 2026 Changes and What Contract Teams Must Do Now

The Draft Alternative Dispute Resolution Bill Zambia modernises the legal infrastructure for resolving commercial disputes outside the courts. It creates statutory recognition for mediation, updates arbitration procedure to align with the UNCITRAL Model Law, limits court intervention in arbitral proceedings, and establishes an enforcement mechanism for mediated settlement agreements. The ZLDC published its final development document on May 22, 2025, and the Draft Bill was formally presented to Government in February 2026.

Contract teams should act now, even before parliamentary enactment. The following four actions should be prioritised immediately:

• Immediate (0–30 days). Audit your clause bank, identify every arbitration and mediation clause in active commercial contracts governed by Zambian law. Flag clauses that reference outdated statutory provisions or lack a designated seat of arbitration.
• Short-term (30–60 days). Prepare redline drafts of model arbitration clauses using UNCITRAL-aligned language, including tribunal appointment mechanisms, emergency interim relief provisions, and express seat and curial law designations.
• Medium-term (60–90 days). Draft and circulate mediation enforcement clauses and multi-tier dispute resolution clauses (mediation followed by arbitration) for use in new contracts. Include confidentiality and privilege language consistent with the Draft Bill’s mediation provisions.
• Ongoing. Add transitional and savings clauses to high-value contracts executed before enactment, preserving the parties’ chosen dispute resolution regime while providing for automatic adoption of the new framework once commenced.

Background: Current ADR Landscape in Zambia and the Draft ADR Bill Objectives

Alternative dispute resolution in Zambia has historically operated within a fragmented legislative environment. Arbitration has been governed by legacy statutory provisions, while mediation has largely functioned outside a comprehensive statutory framework, relying instead on contractual agreement between parties and ad hoc institutional rules. The World Bank has documented the strain on Zambian courts and identified ADR capacity-building as a priority for improving the commercial justice system. Against this backdrop, the ZLDC embarked on a multi-year legislative development process to create a modern, unified ADR statute.

The five principal types of alternative dispute resolution relevant to commercial contracts in Zambia are:

• Negotiation. Direct discussion between parties to reach a voluntary settlement without third-party involvement.
• Mediation. A facilitated process where a neutral mediator assists parties in reaching a mutually acceptable resolution, the mediator does not impose a binding decision.
• Conciliation. Similar to mediation but the conciliator may propose terms of settlement for the parties to consider.
• Arbitration. A binding adjudicative process where one or more arbitrators render an enforceable award, the primary ADR mechanism for high-value commercial disputes.
• Dispute boards. Standing or ad hoc panels (common in construction and infrastructure contracts) that provide real-time determinations during project execution.

What Is in the Draft ADR Bill?

The Draft ADR Bill, as published by the ZLDC, seeks to achieve three core objectives. First, it aligns Zambia’s arbitration regime with the UNCITRAL Model Law on International Commercial Arbitration, bringing Zambian arbitration procedure into conformity with widely accepted international standards. Second, it creates a clear statutory basis for mediation, including provisions governing the conduct of mediation proceedings and, critically, the enforcement of mediated settlement agreements. Third, it consolidates and modernises the procedural rules applicable to ADR in Zambia, addressing gaps in tribunal appointment, interim measures, confidentiality, and the scope of permissible court intervention.

Timeline of Key Milestones

Key Changes Affecting Arbitration Under the Zambia ADR Bill 2026

The Draft ADR Bill introduces several procedural reforms that will directly affect how arbitration clauses in commercial contracts in Zambia should be drafted. Understanding these changes is essential for any in-house counsel or contract manager responsible for dispute resolution provisions in Zambian-law agreements.

Party Autonomy and Seat Selection

Consistent with the UNCITRAL Model Law, the Draft Bill reinforces party autonomy as the foundational principle of arbitration. Parties are free to agree on the number of arbitrators, the method of their appointment, the procedural rules governing the arbitration, and the seat (juridical place) of the proceedings. This has direct consequences for drafting arbitration clauses in Zambia: every clause should now expressly designate a seat, specify whether institutional or ad hoc rules apply, and set out the tribunal appointment mechanism.

Where the clause is silent on the seat, the arbitral tribunal or the appointing authority will make the determination, introducing an element of uncertainty that well-drafted clauses should eliminate. Industry observers expect that Lusaka will remain the default seat for domestic commercial arbitrations, but cross-border contracts should explicitly address seat selection to anchor the curial law and supervisory jurisdiction.

Interim Relief and Emergency Arbitrators

The Draft Bill addresses interim and conservatory measures, empowering arbitral tribunals to grant interim relief at the request of a party. This is a significant modernisation. Under older frameworks, parties often had to apply to Zambian courts for interim measures even where an arbitration agreement existed, creating delay and undermining the efficiency of the arbitral process.

For clause drafters, the practical implication is to include express language authorising the tribunal to grant interim measures, and, where institutional rules permit, to provide for emergency arbitrator procedures before the tribunal is constituted. This is particularly important in time-sensitive commercial contracts involving supply chains, construction milestones, or perishable commodities.

Court Intervention and Limited Judicial Review

One of the hallmarks of UNCITRAL Model Law alignment is the principle that courts should not intervene in arbitral proceedings except as expressly provided by the statute. The Draft ADR Bill adopts this approach, limiting court intervention to specific circumstances such as the appointment of arbitrators where the agreed mechanism fails, challenges to arbitrators, enforcement of interim measures ordered by a tribunal, and setting aside of arbitral awards on narrow, defined grounds.

For contract teams, this reinforces the importance of self-contained arbitration clauses. A well-drafted clause under the new regime should anticipate the reduced role of courts and ensure that fallback mechanisms (substitute appointing authority, challenge procedures, and emergency measures) are addressed within the clause itself rather than relying on residual court jurisdiction.

Key Changes Affecting Mediation and Settlement Enforceability

The introduction of a statutory framework for mediation law in Zambia is one of the most consequential aspects of the Draft ADR Bill. Until now, mediation in Zambia has operated largely as a contractual and voluntary process, with the enforceability of mediated settlement agreements depending on general contract law principles. The Draft Bill changes this by providing specific statutory provisions governing mediation proceedings and, most importantly, creating a mechanism for the enforcement of mediation agreements.

Are Mediated Settlements Automatically Enforceable?

Under the Draft Bill’s provisions, mediated settlement agreements gain statutory recognition, which means they are no longer treated merely as private contracts subject to ordinary breach-of-contract proceedings. The Bill contemplates an enforcement mechanism through the courts, enabling a party to apply for enforcement of a mediated settlement agreement in a manner analogous to the enforcement of an arbitral award. The likely practical effect will be to reduce the time and cost associated with enforcing settlement terms, and to provide parties with greater confidence that mediation outcomes will be honoured.

For contract drafters, this means that mediation clauses should now include language expressly referencing the statutory enforcement framework. Settlement agreements reached through mediation should contain specific provisions confirming the parties’ consent to enforcement under the Draft Bill’s mechanism, identifying the competent court for enforcement applications, and setting out any conditions precedent to enforcement (such as certification by the mediator that the settlement was voluntarily concluded).

Confidentiality and Privilege: Practical Drafting Tips

The Draft ADR Bill addresses confidentiality in mediation proceedings, seeking to protect communications made during mediation from disclosure in subsequent arbitration or court proceedings. This is essential for the integrity of the mediation process, parties will not negotiate candidly if their concessions can be used against them later.

Early indications suggest that the Bill will establish a default confidentiality regime for mediation, though parties may contractually modify or extend its scope. Clause drafters should therefore:

• Include an express confidentiality clause in the mediation agreement, specifying the scope of protected communications (offers, admissions, proposals, mediator’s notes).
• Address the privilege question by stating that mediation communications are privileged and inadmissible in any subsequent arbitration, litigation, or regulatory proceeding, except where disclosure is required by law or necessary to enforce the settlement agreement itself.
• Define exceptions clearly, for example, information that was already in the public domain or independently discoverable should not be protected.
• Bind all participants, the confidentiality obligation should extend to the parties, their advisers, the mediator, and any observers or support staff present during mediation sessions.

Practical Drafting: Model Arbitration and Mediation Clauses and Checklist

This section provides model clauses that contract teams can adapt for use in commercial contracts governed by Zambian law. Each clause is annotated with guidance on when to use it and how to customise it. These models reflect the UNCITRAL alignment anticipated by the Zambia ADR Bill and current best practice in drafting ADR clauses.

Model Arbitration Clause (UNCITRAL Alignment)

“Any dispute, controversy, or claim arising out of or in connection with this contract, or the breach, termination, or invalidity thereof, shall be settled by arbitration in accordance with [specify rules, e.g., the UNCITRAL Arbitration Rules / rules of a designated institution]. The number of arbitrators shall be [one/three]. The seat of arbitration shall be Lusaka, Zambia. The language of the arbitration shall be English. The governing law of this contract shall be the laws of Zambia.”

When to use: This is the standard clause for domestic and cross-border commercial contracts where parties want a binding, final determination. It should be included in all material contracts, supply agreements, joint ventures, shareholder agreements, and services contracts. Specify the seat expressly to anchor supervisory jurisdiction. Choose institutional rules (such as those of a recognised arbitration centre) for greater procedural certainty, or UNCITRAL Arbitration Rules for ad hoc proceedings.

Model Mediation Clause and Settlement Enforcement Clause

“Before commencing arbitration under Clause [X], the parties shall attempt in good faith to resolve the dispute through mediation administered by [specify institution or nominating body]. The mediation shall be conducted in Lusaka, Zambia, and shall be completed within [30/60] days of the appointment of the mediator, unless the parties agree to extend the period. All communications made during the mediation are confidential, privileged, and inadmissible in any subsequent proceedings, except as required by law or for the enforcement of any settlement agreement.”

“Any settlement agreement reached through mediation shall be recorded in writing, signed by the parties and the mediator, and shall be enforceable in accordance with the provisions of the Alternative Dispute Resolution Act [when enacted] or, pending enactment, as a binding contract under the laws of Zambia.”

When to use: Include this clause in any contract where early, cost-effective resolution is a priority. The time-bound mediation window (30 or 60 days) prevents the process from becoming a delay tactic. The settlement enforcement language future-proofs the clause by referencing both the anticipated statute and existing contract law.

Emergency Interim Relief Clause

“Notwithstanding the mediation and arbitration provisions of this contract, either party may apply to an emergency arbitrator (if available under the applicable arbitral rules) or to the competent courts of Zambia for urgent interim or conservatory measures, including injunctive relief and preservation of assets. Any such application shall not be deemed a waiver of the arbitration agreement.”

When to use: Essential for contracts involving time-sensitive obligations, perishable goods, intellectual property, or significant financial exposure where delay in obtaining relief could cause irreparable harm.

Multi-Tier Dispute Resolution Clause (Mediation Then Arbitration)

“Any dispute arising out of or in connection with this contract shall be resolved in accordance with the following escalation procedure:

(a) The parties shall first attempt to resolve the dispute through direct negotiation between their authorised senior representatives within [14] days of written notice of the dispute.

(b) If the dispute is not resolved through negotiation, the parties shall submit the dispute to mediation in accordance with Clause [Y] of this contract.

(c) If the dispute is not resolved through mediation within [30/60] days of the mediator’s appointment, either party may refer the dispute to final and binding arbitration in accordance with Clause [X] of this contract.”

When to use: This is the recommended structure for high-value, long-term commercial relationships (joint ventures, concession agreements, infrastructure contracts) where preserving the business relationship is as important as resolving the dispute. The escalation tiers create structured opportunities for settlement before the cost and formality of arbitration.

The following checklist provides a step-by-step guide for updating arbitration clauses in existing contracts:

1. Identify every active contract with an arbitration or dispute resolution clause governed by Zambian law.
2. Review each clause against the UNCITRAL Model Law requirements: does it specify the seat, number of arbitrators, appointment mechanism, applicable rules, and governing law?
3. Add or update the seat designation, specify Lusaka, Zambia (or another agreed seat) expressly.
4. Insert an emergency interim relief provision if the clause currently relies solely on court applications for interim measures.
5. Add a mediation tier before arbitration, with a time-bound window and confidentiality language.
6. Include a settlement enforcement clause referencing the statutory mechanism under the Draft ADR Bill (when enacted) and existing contract law as a fallback.
7. Draft and insert a transitional/savings clause for contracts executed before enactment (see below).
8. Circulate redlines to counterparties and negotiate amendments, prioritise high-value and long-duration contracts.
9. Update your standard clause bank with the new model clauses for use in all future contracts.

Transitional and Enforcement Considerations for Contracts Executed Before the Zambia ADR Bill

One of the most common concerns for in-house counsel is how the new legislation will affect contracts that were signed before the Bill becomes law. The general principle in Zambian law, consistent with common law jurisdictions, is that new legislation applies prospectively unless the statute expressly provides for retrospective application. Industry observers expect the Draft ADR Bill to follow this approach, meaning arbitration agreements concluded before commencement will remain valid and enforceable under the legal regime in force at the time of execution.

However, procedural provisions of the new Act may apply to arbitrations commenced after its commencement date, regardless of when the underlying contract was signed. This creates a potential mismatch: a clause drafted under the older framework may not adequately address the procedural options (emergency arbitrators, expanded interim relief, mediation enforcement) available under the new statute.

How to Draft a Savings and Transition Clause

“The dispute resolution provisions of this contract shall be governed by the laws in force at the date of execution of this contract. However, in the event that the Alternative Dispute Resolution Act [when enacted] comes into force during the term of this contract, the parties agree that: (a) any arbitration or mediation commenced after the commencement date of the Act shall be conducted in accordance with the procedural provisions of the Act; and (b) any arbitration or mediation commenced before the commencement date of the Act shall continue under the procedural provisions in force at the date of commencement of the arbitration or mediation, unless the parties agree otherwise in writing.”

When to use: Include this clause in all contracts signed during the transitional period between the Bill’s handover to Government and its eventual enactment and commencement. It provides certainty for both parties while preserving flexibility to adopt the new framework for future disputes.

Practical Enforcement Steps for Pre-Existing Agreements

For contracts already executed without transitional clauses, parties should consider executing supplementary agreements or side letters that update the dispute resolution provisions. Where the counterparty is unwilling to amend, the existing clause remains enforceable, but parties should be aware that procedural aspects of any arbitration commenced after the new Act may be governed by the updated statute. Legal counsel should review each material contract on a case-by-case basis to assess enforcement risk.

Risk Management: Negotiation, Dispute Avoidance and Cost/Timing Impacts

The modernisation of ADR legislation in Zambia is expected to reduce dispute resolution timelines and costs for commercial parties. Mediation, in particular, offers a significantly lower-cost path to resolution than arbitration or litigation, and the statutory enforcement of mediated settlements under the Zambia ADR Bill will increase confidence in the process.

When deciding between mediation and arbitration for a particular contract, consider the following factors:

• Nature of the dispute. Mediation is best suited to disputes where the parties have an ongoing commercial relationship and a negotiated outcome is more valuable than a winner-takes-all determination. Arbitration is appropriate where a binding, enforceable decision is necessary.
• Value and complexity. High-value, complex disputes (cross-border transactions, construction, energy) often benefit from a multi-tier clause starting with mediation and escalating to arbitration.
• Confidentiality requirements. Both mediation and arbitration offer confidentiality advantages over court proceedings. The Draft Bill strengthens confidentiality protections for mediation.
• Enforcement needs. If enforcement across multiple jurisdictions is required, arbitration under UNCITRAL-aligned rules, supported by the New York Convention, remains the preferred mechanism.
• Provider selection. Choose an established ADR institution with experience in Zambian commercial disputes, or specify UNCITRAL Arbitration Rules for ad hoc proceedings. Consider the availability of qualified mediators and arbitrators in the relevant sector.

Conclusion and Next Steps: Preparing Your Contracts for the Zambia ADR Bill

The Draft ADR Bill 2026 marks a defining moment for commercial dispute resolution in Zambia. By aligning with the UNCITRAL Model Law and introducing statutory recognition for mediation, including the enforcement of mediated settlement agreements, the Bill will bring Zambia’s ADR framework into line with international best practice. For businesses, the practical consequences are clear: commercial contracts Zambia must be reviewed and updated to reflect the new procedural landscape.

In-house counsel and contract managers should begin the clause review process now, using the model clauses and checklist provided in this guide. Prioritise high-value and long-duration contracts, insert transitional and savings clauses where enactment timing is uncertain, and ensure that every new contract includes a modern, UNCITRAL-aligned arbitration clause and a mediation tier with settlement enforcement language. Staying ahead of the Zambia ADR Bill is not merely a compliance exercise, it is an opportunity to build more resilient, enforceable, and cost-effective dispute resolution mechanisms into your commercial relationships.
