Dispute Resolution Lawyers Nigeria 2026, Arbitration & Mediation Bill: Drafting Clauses and Enforcing Awards

Nigeria’s dispute resolution landscape is undergoing its most significant transformation in decades, driven by the Arbitration and Mediation Bill 2026 and the accompanying National Arbitration Policy. For in-house counsel, general counsels and commercial lawyers who rely on dispute resolution lawyers in Nigeria, the reforms demand immediate attention: arbitration clause templates need updating, enforcement workflows are changing, and emergency interim relief from Nigerian courts is now on a firmer statutory footing. This guide delivers the clause-level, checklist-driven guidance that practitioners need to draft enforceable ADR provisions and navigate the new framework with confidence.

Executive Summary, What GCs Must Know About Nigeria’s 2026 ADR Reforms

The Arbitration and Mediation Bill restructures Nigeria’s ADR framework, replacing the aging Arbitration and Conciliation Act of 1988 with provisions aligned to international best practice. Below are the five practical consequences every general counsel and contracting team should absorb before the next contract negotiation.

• Clause drafting overhaul required. The Bill introduces express statutory language on seat designation, arbitrator appointment fall-back mechanisms, and scope of arbitrable disputes, existing boilerplate clauses risk unenforceability.
• Emergency interim relief codified. Courts are now expressly empowered to grant interim measures in support of arbitration proceedings, and recent Lagos State High Court decisions from January 2026 have tested those boundaries in real time.
• Enforcement streamlined. The Bill tightens the grounds on which courts may refuse recognition and enforcement of awards, bringing Nigeria closer to a pro-enforcement default position under the New York Convention.
• Mediation given statutory backbone. For the first time, a comprehensive mediation framework in Nigeria has statutory recognition, creating enforceable mediation settlement agreements and encouraging multi-tier ADR clauses.
• Seat vs venue distinction clarified. Practitioners must now specify the legal seat of arbitration separately from the hearing venue, failure to do so may create jurisdictional ambiguity and enforcement risk.

Industry observers expect these changes to accelerate Nigeria’s positioning as a credible arbitration seat for West African and pan-African commercial disputes, particularly in the oil and gas and infrastructure sectors.

The Arbitration and Mediation Bill 2026, What Changed

The Bill, introduced before the National Assembly and supported by the Federal Ministry of Justice’s National Arbitration Policy, represents a wholesale modernisation of Nigeria’s arbitration legislation. It draws heavily from the UNCITRAL Model Law on International Commercial Arbitration and, for the first time, integrates a standalone mediation statute within the same legislative instrument.

Key Statutory Changes at a Glance

The Bill makes structural amendments across five core areas that directly affect how dispute resolution lawyers in Nigeria advise their clients:

• Expanded definition of arbitration agreements. The Bill adopts the UNCITRAL Model Law standard, recognising arbitration agreements contained in electronic communications, exchange of statements of claim and defence, and documents incorporated by reference, moving beyond the narrow “written agreement” formulation of the 1988 Act.
• Court assistance powers. New provisions expressly authorise courts to grant interim measures (including asset preservation, anti-dissipation and evidentiary orders) in support of both domestic and international arbitration proceedings, whether seated in Nigeria or abroad.
• Arbitrator appointment and challenge. The Bill introduces a default appointment mechanism through a designated appointing authority where parties fail to agree, and codifies challenge and removal procedures with strict timelines.
• Mediation recognition. Part II of the Bill establishes a mediation framework that gives statutory force to mediation settlement agreements, making them directly enforceable as if they were court orders upon registration.
• Enforcement regime. The grounds for refusing enforcement are restated in language that mirrors Article V of the New York Convention, narrowing the discretion historically exercised by Nigerian courts and reducing the scope for dilatory challenges.

Three Practical Implications for Counsel

1. For clause drafting: Reference the Bill’s definitions explicitly, specify seat, and name institutional rules or the ad hoc procedure to avoid default-appointment delays.
2. For enforcement: Prepare enforcement applications with evidence that pre-empts the limited grounds for refusal now codified in the Bill, this front-loads the work but shortens timelines considerably.
3. For interim relief: Always include an express emergency relief clause and identify whether the court or the tribunal (or both) may grant urgent measures before the tribunal is fully constituted.

Choosing the Forum: Arbitration vs Mediation vs Nigerian Courts, A Decision Checklist

Forum selection is the single most consequential decision a contracting party makes before a dispute crystallises. Under the 2026 reforms, the expanded mediation framework in Nigeria means there are now three credible options, each with distinct advantages, limitations and cost profiles.

Use the following six-point decision checklist when advising on forum selection:

1. Confidentiality requirements. If commercial sensitivity is paramount (trade secrets, pricing, joint-venture economics), arbitration or mediation will serve better than open court proceedings.
2. Enforcement geography. If the award may need enforcement outside Nigeria, arbitration seated in Nigeria under the New York Convention framework is the most portable option.
3. Value and complexity. High-value, technically complex disputes (oil and gas, infrastructure, energy) favour arbitration with sector-specialist arbitrators. Lower-value commercial disputes may resolve faster through mediation.
4. Relationship preservation. Where ongoing commercial relationships matter, joint ventures, long-term supply agreements, mediation allows parties to craft a commercial settlement rather than a binary win/lose outcome.
5. Speed and cost. Mediation is typically faster and cheaper than arbitration. However, if mediation fails and arbitration follows, the combined cost may exceed a well-managed arbitration from the outset. Multi-tier clauses must account for this.
6. Interim relief urgency. If there is a real risk of asset dissipation or evidence destruction, the ability to access emergency interim relief through Nigerian courts (now expressly provided for by the Bill) makes arbitration with court-assistance provisions the strongest choice.

Sector Considerations, Oil and Gas, Infrastructure, and Fintech

Sector context significantly affects forum choice. In the Nigerian oil and gas sector, where production-sharing contracts and joint-operating agreements routinely involve sovereign entities and large capital commitments, arbitration remains the default, and dispute resolution lawyers in Nigeria consistently advise specifying international institutional rules with a Nigerian seat. For background on the regulatory lifecycle in this sector, see our guide on regulatory compliance in Nigeria’s oil and gas lifecycle.

Infrastructure projects, particularly those involving public-private partnerships, introduce additional complexity: sovereign immunity, local content requirements for foreign companies, and multi-party structures all affect clause design. In the fintech space, where disputes frequently arise from payment processing failures, regulatory enforcement and data-sharing agreements, mediation is gaining traction. Parties operating in this space should also review the regulatory context for setting up a fintech company in Nigeria and the e‑commerce legal framework before selecting a dispute forum.

Drafting Enforceable Arbitration Clauses in 2026, Annotated Clause Bank

Effective arbitration clause drafting is the foundation of a workable dispute resolution strategy. The annotated clause bank below provides five template clauses, each tailored to a different scenario. Every clause is designed to be compatible with the Arbitration and Mediation Bill and reflects best practice guidance from leading arbitral institutions.

Clause 1, Basic Arbitration Clause

“Any dispute, controversy or claim arising out of or relating to this contract, or the breach, termination or invalidity thereof, shall be settled by arbitration in accordance with [named institutional rules / the UNCITRAL Arbitration Rules]. The number of arbitrators shall be [one/three]. The language of the arbitration shall be English.”

Annotation: This is the minimum viable arbitration clause. It names the dispute scope, institutional rules, number of arbitrators and language. However, it omits seat designation and emergency relief provisions, both of which the 2026 Bill now requires parties to address expressly for maximum enforceability. Use this only as a starting template, not a final clause.

Clause 2, Seat-Specified Clause

“Any dispute arising out of or in connection with this contract shall be referred to and finally resolved by arbitration under [named institutional rules]. The seat, or legal place, of arbitration shall be Lagos, Nigeria. The venue of hearings may be Lagos or such other location as the tribunal may direct. The governing law of this contract shall be the laws of the Federal Republic of Nigeria.”

Annotation: This clause expressly distinguishes seat from venue, critical under the 2026 Bill. Specifying Lagos as the legal seat means Nigerian courts have supervisory jurisdiction and the award is a “domestic” award for enforcement purposes, while permitting hearings elsewhere if logistics require it.

Seat vs Venue, Practical Comparison

Clause 3, Emergency Interim Relief Clause

“Prior to the constitution of the arbitral tribunal, either party may apply to the emergency arbitrator under [named institutional rules] for urgent interim or conservatory measures. Nothing in this clause shall prevent either party from seeking interim relief from any court of competent jurisdiction, including the courts of the seat of arbitration, where it considers such measures urgently necessary to preserve assets, evidence or the status quo.”

Annotation: This clause preserves dual-track access to emergency relief, through the institution’s emergency arbitrator mechanism and through Nigerian courts. Under the 2026 Bill, failing to include this language may create ambiguity about whether a party has waived its right to seek court-ordered measures.

Clause 4, Multi-Tier Clause (Mediation Then Arbitration)

“Any dispute arising out of or in connection with this contract shall first be referred to mediation under [named mediation rules / the Lagos Multi-Door Courthouse Mediation Rules]. If the dispute is not settled by mediation within [30/60] days of the commencement of the mediation, or such further period as the parties may agree in writing, the dispute shall be referred to and finally resolved by arbitration under [named institutional rules]. The seat of arbitration shall be Lagos, Nigeria.”

Annotation: Multi-tier clauses are increasingly favoured in Nigeria, particularly given the Bill’s new mediation framework. The critical drafting point is the escalation trigger: use a defined time limit and a clear written-agreement extension mechanism. Vague language (“the parties shall endeavour to resolve…”) has historically been treated by Nigerian courts as unenforceable aspirational wording.

Multi-Tier Escalation, Red Flags to Avoid

• No time limit on mediation step. Without a fixed period, the mediation tier becomes an indefinite stay on arbitration, effectively a roadblock.
• No “final and binding” language for arbitration tier. Always include “finally resolved by arbitration” to prevent re-litigation in courts.
• No fallback appointing authority. If neither party nominates a mediator within the agreed period, the clause should designate a default appointing body.

Clause 5, Investor-State / State-Contract Clause

“Any dispute between the Investor and the Host State arising out of or relating to this Agreement shall be settled by arbitration under [ICSID Rules / UNCITRAL Rules]. The Host State hereby irrevocably waives any claim to sovereign immunity from the jurisdiction of the tribunal and from the enforcement of any award rendered pursuant to this clause, to the fullest extent permitted by applicable law.”

Annotation: State-contract clauses in Nigeria require an express waiver of sovereign immunity. Without it, enforcement proceedings may stall on jurisdictional objections. This clause is essential for oil and gas, infrastructure and large-scale investment contracts involving federal or state government entities.

Emergency Interim Relief, Courts and Arbitral Tribunals After the Bill

One of the most consequential changes in the Arbitration and Mediation Bill is the express codification of the power of Nigerian courts to grant emergency interim relief in aid of arbitration. This resolves a long-standing ambiguity under the 1988 Act, where court assistance was available in practice but lacked clear statutory authority. Recent January 2026 decisions from the Lagos State High Court have tested and affirmed these provisions in live proceedings, signalling an increasingly pro-arbitration judicial posture.

Step-by-Step: Seeking Emergency Interim Relief

1. Identify the appropriate forum. If the arbitral tribunal is already constituted, apply to the tribunal first (or concurrently to the tribunal and the court if urgency demands it). If the tribunal is not yet constituted, apply directly to the court of the seat or to the institution’s emergency arbitrator.
2. Prepare supporting evidence. Assemble a sworn affidavit setting out the factual basis for urgency, the risk of irreparable harm, the relief sought (asset freezing, anti-dissipation, evidence preservation), and the balance-of-convenience analysis.
3. File the application. At the High Court of the seat (e.g., Lagos State High Court), file a motion on notice supported by the arbitration agreement, evidence of the pending or contemplated arbitration, and the affidavit evidence.
4. Serve and attend hearing. Courts are granting expedited hearings for arbitration-related interim applications, particularly where asset-dissipation risk is demonstrated.
5. Obtain and enforce the order. Once granted, the court order is immediately enforceable, serve it on relevant third parties (banks, registries, counterparties) and notify the arbitral tribunal of the court’s order.
6. Report to the tribunal. Any court-granted interim measure should be disclosed to the tribunal once constituted, and the tribunal retains the power to modify, suspend or revoke such measures.

Enforcement of Awards in Nigeria, Domestic and Foreign Awards

The enforcement of awards in Nigeria is the litmus test of the arbitration system’s credibility. The 2026 Bill significantly tightens the grounds for refusal of enforcement, aligning Nigerian law with the pro-enforcement bias of the New York Convention. For dispute resolution lawyers in Nigeria, this means enforcement applications can be prepared with greater confidence, but only if the underlying award and arbitration process are procedurally sound.

Enforcing Domestic Awards

Domestic awards (those rendered in arbitrations seated in Nigeria) are enforced by application to the High Court of the state where the seat is located. The process follows these steps:

1. Obtain the original or certified copy of the award and the original or certified copy of the arbitration agreement.
2. File an ex parte application (originating motion) at the High Court for leave to enforce the award as a judgment of the court.
3. Serve the respondent. Once leave is granted, serve the order on the award debtor, who may apply to set aside the order within the permitted period.
4. Respond to any challenge. Under the Bill, challenges are limited to the grounds mirroring Article V of the New York Convention: incapacity of a party, invalidity of the arbitration agreement, procedural irregularity, award beyond the scope of submission, or public policy, a deliberately narrow list.
5. Obtain final enforcement order. If no successful challenge is mounted, the award is enforceable as a court judgment with all attendant execution mechanisms (garnishee proceedings, attachment of assets, committal).

Enforcing Foreign Awards Under the New York Convention

Nigeria is a signatory to the New York Convention, and the 2026 Bill restates the Convention’s enforcement regime with enhanced procedural clarity. To enforce a foreign arbitral award:

1. File an application at the High Court accompanied by the duly authenticated original award (or certified copy), the arbitration agreement, and certified translations where the award is not in English.
2. The court must recognise and enforce the award unless the respondent demonstrates one of the limited refusal grounds, identical to those for domestic awards and drawn directly from Article V of the Convention.
3. The award debtor bears the burden of proof on refusal grounds, the applicant does not need to prove that the award is valid; the respondent must prove it is not.

Early indications suggest that the Bill’s restated enforcement provisions will reduce the average time for uncontested foreign award enforcement, as courts will have clearer statutory guidance and narrower grounds for judicial discretion.

Investor-State Arbitration and State Contracts, Practical Cautions

Investor-state arbitration in Nigeria carries unique risks that commercial arbitration does not. Federal and state government entities regularly enter into production-sharing contracts, concession agreements and public-private partnership agreements, but the enforceability of arbitration clauses in those contracts depends on careful drafting around sovereign immunity, statutory procurement requirements and the scope of arbitrable disputes.

• Sovereign immunity waivers. Nigerian government entities may invoke sovereign immunity to resist enforcement. Always include an express, irrevocable waiver of immunity from both the jurisdiction of the tribunal and the enforcement of the award (see Clause 5 above).
• Scope of arbitrable disputes. Certain regulatory and administrative decisions may fall outside the scope of arbitration under Nigerian law. Draft the arbitration clause to cover “all disputes arising out of or in connection with this Agreement, including its formation, validity and termination”, and carve out only what is legally non-arbitrable.
• Sector-specific risks. In oil and gas contracts, local content obligations and regulatory approvals may interact with arbitration proceedings. Practitioners should review the role of arbitration in resolving disputes in Nigeria for foundational context on how Nigerian courts have historically treated state-party arbitration agreements.
• Bilateral investment treaties. Where applicable, check whether a relevant BIT provides an additional arbitration route (typically ICSID or UNCITRAL) that may override or supplement the contractual arbitration clause.

The likely practical effect of the 2026 reforms will be to make investor-state arbitration more predictable, but the threshold discipline of precise clause drafting remains the single most important risk-mitigation tool.
