Arbitration and Mediation Bill Nigeria 2026: What Businesses Need to Know

Nigeria’s dispute resolution landscape has undergone its most significant transformation in over three decades, driven by the Arbitration and Mediation Bill Nigeria 2026 reform cycle that began with the Senate’s passage of the Bill in May 2022 and culminated in the Arbitration and Mediation Act 2023 (AMA) and the subsequent rollout of the National Arbitration Policy. For in-house counsel, contract managers and foreign investors operating in or alongside Nigerian counterparties, these changes demand an immediate review of existing arbitration clauses, enforcement playbooks and mediation strategies. This guide provides the practical tools, clause templates, enforcement checklists and step-by-step roadmaps, needed to align commercial contracts with the current framework and to protect award enforceability across domestic and cross-border disputes.

Executive Summary: What Businesses Must Do Now

The combined effect of the AMA and the National Arbitration Policy is a consolidated, modernised arbitration and mediation regime that limits unnecessary court intervention, recognises mediation settlement agreements, and positions Nigeria as a competitive seat for international commercial arbitration. Businesses that fail to update their dispute resolution clauses and enforcement protocols risk unenforceable agreements, procedural delays and avoidable costs.

Immediate action checklist:

• Audit all existing arbitration clauses. Replace references to the repealed Arbitration and Conciliation Act (Cap A18, LFN 2004) with the Arbitration and Mediation Act 2023. Clauses citing the old statute may create ambiguity that invites challenge.
• Specify seat, governing law and institutional rules explicitly. The AMA places renewed emphasis on party autonomy. Ambiguous or silent clauses on seat and applicable law are a leading cause of enforcement failures in Nigerian courts.
• Incorporate multi-tier dispute resolution clauses where appropriate. The AMA formally recognises mediation, making mediation-first clauses enforceable as a contractual prerequisite to arbitration.
• Prepare an enforcement playbook. Map the domestic and foreign award enforcement steps outlined later in this guide, including asset-preservation measures, court filing requirements and anticipated timelines.
• Evaluate seat selection. With the National Arbitration Policy actively promoting Nigerian arbitral institutions, re-examine whether a Nigerian seat (Lagos, Abuja) now offers advantages over traditional neutral seats for contracts with Nigerian counterparties.

Background: Legislative and Policy Timeline (2022–2026)

Understanding the Arbitration and Mediation Bill Nigeria 2026 reform cycle requires mapping three interconnected developments: the legislative passage, the enactment of the statute, and the policy rollout that followed. The table below summarises the chronology and its commercial implications.

Key Dates Explained

The Senate’s passage of the Bill on 10 May 2022 was the critical trigger. Following bicameral concurrence and presidential assent, the AMA took effect in 2023, formally repealing Cap A18. The Act draws on the UNCITRAL Model Law on International Commercial Arbitration while incorporating Nigeria-specific provisions on mediation, confidentiality and interim measures. For a deeper understanding of how arbitration has historically operated in Nigeria, see the role of arbitration in resolving disputes in Nigeria.

The National Arbitration Policy, covered extensively by Global Arbitration Review in April 2026, represents the implementation layer. It articulates government objectives, institutional development, judicial training, recognition of arbitral centres, that transform the statutory framework into an operational ecosystem. Industry observers expect this policy to accelerate Nigeria’s competitiveness as an arbitral seat within the next three to five years.

Key Changes in the Arbitration and Mediation Bill Nigeria 2026 Reform Cycle

The AMA introduced several structural changes that directly affect how businesses draft dispute clauses, conduct arbitral proceedings and enforce awards. Below are the most commercially significant reforms, with guidance on their immediate drafting impact.

Court Intervention and Stay of Proceedings

The AMA significantly curtails the scope for courts to intervene in arbitral proceedings. Where a party commences court proceedings in respect of a matter that is the subject of a valid arbitration agreement, the court is now required to stay those proceedings and refer the parties to arbitration, provided the application is made before the party seeking the stay takes any step in the court proceedings. This codifies the pro-arbitration principle and narrows the historic tendency of Nigerian courts to entertain jurisdictional challenges that delayed proceedings.

Why it matters: Under the old Act, parties frequently exploited procedural ambiguities to obtain court injunctions that frustrated arbitral proceedings. The AMA’s mandatory stay provision gives the arbitral tribunal primacy over jurisdictional questions, reducing the risk of parallel proceedings.

Immediate drafting impact: Ensure every arbitration clause contains an unambiguous statement that all disputes arising out of or in connection with the contract shall be referred to and finally resolved by arbitration. Avoid hybrid clauses that simultaneously confer jurisdiction on courts and arbitral tribunals, these create the very ambiguity the AMA is designed to eliminate.

Mediation Recognition and Settlement Agreements

The AMA formally recognises mediation as a distinct dispute resolution mechanism and provides for the enforceability of mediation settlement agreements. A settlement agreement reached through mediation may be converted into a consent arbitral award or recorded as a court consent order, giving it the same binding effect as a judgment. This is a landmark development in mediation law Nigeria 2026 and gives businesses a reliable path from negotiation to enforceable outcome.

Additional key changes include:

• Confidentiality provisions. The AMA establishes a default confidentiality framework for arbitral proceedings unless the parties agree otherwise, strengthening commercial confidence in the process.
• Interim measures and emergency relief. The Act empowers arbitral tribunals to grant interim measures of protection, including preservation of assets and evidence. This reduces dependence on courts for urgent relief and aligns Nigeria with international best practice.
• Public policy as a ground for refusal. The AMA retains public policy as a ground for setting aside or refusing enforcement of an award, but the likely practical effect of the reforms is a narrower judicial interpretation, consistent with the pro-enforcement trend observed across UNCITRAL Model Law jurisdictions.
• Third-party funding. While not explicitly regulated, the AMA’s silence on third-party funding, read alongside evolving judicial attitudes, creates scope for funded arbitrations, particularly in high-value commercial and investor disputes.

National Arbitration Policy Nigeria: Strategic Effects on Seat, Institutions and Enforcement

The National Arbitration Policy Nigeria, formally rolled out between 2024 and 2026, articulates the government’s ambition to position Nigeria as Africa’s leading dispute resolution hub. This is not merely aspirational; the policy contains concrete institutional measures that affect how businesses choose their arbitral seat and which institutions they select.

Choosing Seat vs Venue

The distinction between seat and venue is critical under the AMA. The seat determines the legal framework governing the arbitration (the lex arbitri), including judicial supervisory jurisdiction and the grounds on which an award may be set aside. The venue is simply the physical location of hearings and carries no supervisory implications.

With the National Arbitration Policy actively strengthening Nigerian arbitral institutions and judicial support mechanisms, a Nigerian seat, particularly Lagos or Abuja, now offers meaningful advantages for contracts where assets, counterparties or performance obligations are located in Nigeria. The key considerations are:

• Local enforcement advantage. An award rendered with a Nigerian seat is a domestic award under the AMA, bypassing the more complex recognition steps required for foreign awards under the New York Convention.
• Institutional maturity. The Lagos Court of Arbitration (LCA) and the Nigerian Institute of Chartered Arbitrators (NICArb) have developed institutional rules that are increasingly aligned with international standards.
• Neutral seat rationale. For multinational contracts where both parties have concerns about neutrality, London, Paris or Singapore may still be preferred. However, enforcement of the resulting foreign award in Nigeria will require a separate recognition application.

Institutional Rules and Recognition

The National Arbitration Policy encourages the adoption of institutional arbitration over ad hoc proceedings. Institutional rules provide procedural certainty, administrative support and fee transparency. Businesses should specify institutional rules in their arbitration clauses, whether LCA, ICC, LCIA or NICArb, and avoid the default ad hoc procedure, which can generate procedural disputes that delay resolution. For businesses operating across the broader Nigerian commercial ecosystem, institutional arbitration also provides a more predictable cost framework for dispute budgeting.

Drafting Enforceable Arbitration Clauses: Practical Templates and Pitfalls

The single most important step businesses can take to draft an enforceable arbitration clause in Nigeria is to eliminate ambiguity. The AMA gives full effect to party autonomy, but courts will still scrutinise clauses for clarity, consistency and completeness. Below are three template clauses designed for different commercial contexts, along with annotations explaining each element.

Template 1, General Commercial Contract

“Any dispute arising out of or in connection with this Agreement, including any question regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration under the Rules of the Lagos Court of Arbitration. The seat of arbitration shall be Lagos, Nigeria. The tribunal shall consist of [one / three] arbitrator(s). The language of the arbitration shall be English. The governing law of this Agreement shall be the laws of the Federal Republic of Nigeria.”

• Why this works: It specifies the seat (Lagos), the institutional rules (LCA), the number of arbitrators, the language and the governing law, the five essential elements of an enforceable clause under the AMA.
• What to avoid: Do not use phrasing such as “disputes may be referred to arbitration or the courts”, this creates a permissive, non-binding clause that Nigerian courts have repeatedly declined to enforce.

Template 2, Oil and Gas / Infrastructure Contract

“Any dispute arising out of or in connection with this Agreement shall first be referred to the senior representatives of the parties for negotiation within [30] days. If not resolved, the dispute shall be referred to mediation under the Mediation Rules of the Lagos Court of Arbitration for a period not exceeding [60] days. Any dispute not resolved by mediation shall be finally resolved by arbitration under the ICC Rules of Arbitration. The seat of arbitration shall be Lagos, Nigeria. The tribunal shall consist of three arbitrators. The language of the arbitration shall be English. The governing law shall be the laws of the Federal Republic of Nigeria.”

• Why this works: The multi-tier structure (negotiation → mediation → arbitration) is fully enforceable under the AMA. It is particularly suited to high-value oil and gas and infrastructure contracts where preserving commercial relationships and managing costs before escalation is critical.
• Sector-specific note: For upstream oil and gas operations, consider adding an emergency arbitrator provision for urgent interim relief (e.g., preservation of assets, continuation of operations pending resolution). See the sector-specific section below for an enhanced clause variant.

Template 3, SME and Contractor Agreement

“Any dispute arising out of or in connection with this Agreement shall be finally resolved by arbitration under the Rules of the Nigerian Institute of Chartered Arbitrators. The seat of arbitration shall be [Lagos / Abuja], Nigeria. The tribunal shall consist of a sole arbitrator. The language of the arbitration shall be English. The governing law shall be the laws of the Federal Republic of Nigeria.”

• Why this works: A sole arbitrator and domestic institutional rules (NICArb) keep costs proportionate for SME-scale disputes while ensuring enforceability under the AMA.

Multi-Tier and Mediation-First Clauses

The AMA’s recognition of mediation settlement agreements means that mediation-first clauses are no longer merely aspirational, they create a contractually binding pre-condition to arbitration. When drafting a multi-tier clause, include specific time limits for each tier (e.g., 30 days for negotiation, 60 days for mediation) and a clear escalation trigger (e.g., “if the dispute is not resolved within [X] days of the commencement of mediation, either party may refer it to arbitration”). Without these time limits, a recalcitrant party can use the mediation tier as a delaying tactic.

Seat, Law, Tribunal Composition, Institutional Rules, Language, Consolidation and Joinder

Beyond the core elements, businesses should consider:

• Consolidation and joinder. Multi-party contracts (e.g., joint ventures, consortium agreements) should include explicit consolidation and joinder provisions. The AMA supports party autonomy on these issues, but silence in the clause may leave the tribunal without jurisdiction to join a necessary third party.
• Costs and security. For contracts with counterparties of uncertain financial standing, include a provision requiring security for costs or an escrow mechanism to fund arbitration fees.
• Waiver of appeal. Under the AMA, parties can agree to limit or waive the right to apply to set aside an award. While this is unusual, it may be appropriate for sophisticated commercial parties seeking finality.

Enforcing Domestic and Foreign Arbitral Awards in Nigeria, Step by Step

The ability to enforce an arbitration award in Nigeria is the ultimate test of whether the dispute resolution clause achieved its purpose. The AMA establishes two parallel enforcement pathways: one for domestic awards (awards rendered with a Nigerian seat) and another for foreign awards (awards rendered outside Nigeria, typically enforced under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which Nigeria is a party).

Domestic award enforcement, six-step roadmap:

1. Obtain the final, signed award. Ensure it is in writing, signed by the arbitrator(s) and states the seat of arbitration and the date.
2. File a recognition application. Apply to the High Court of the state in which enforcement is sought (typically where the respondent’s assets are located) for leave to enforce the award as a judgment of the court.
3. Serve the respondent. The respondent must be given notice of the recognition application and an opportunity to raise objections.
4. Defeat any setting-aside application. The respondent may apply to set aside the award on limited grounds (see below). Prepare counter-arguments in advance.
5. Obtain the court order. Once recognised, the award has the same effect as a judgment and can be enforced through standard execution procedures (garnishee orders, attachment of assets, committal).
6. Execute against assets. Identify and preserve the respondent’s assets early, ideally before or simultaneously with the recognition application, using freezing orders or Mareva-type injunctions where available.

Foreign award enforcement, parallel steps to enforce a foreign award in Nigeria:

1. Verify Nigeria’s treaty obligations. Nigeria is a party to the New York Convention. A Convention award rendered in a contracting state benefits from the Convention’s pro-enforcement presumption.
2. Apply to the High Court. File the duly authenticated original award or a certified copy, together with the original arbitration agreement or a certified copy, at the appropriate High Court.
3. Supply certified translations. If the award or arbitration agreement is not in English, provide a certified English translation.
4. Respond to objections. The respondent may oppose enforcement on the limited grounds set out in the AMA (mirroring Article V of the New York Convention): incapacity, invalid arbitration agreement, lack of proper notice, excess of jurisdiction, procedural irregularity, or public policy.
5. Obtain recognition and enforce. Once recognised, the foreign award is enforceable as a domestic judgment.

Setting Aside Applications, Grounds and Counter-Strategies

The most common grounds invoked to set aside or resist enforcement of awards in Nigeria are public policy and jurisdictional objections. The AMA’s narrowing of court intervention means that setting-aside applications are expected to face greater judicial scrutiny. Businesses can prepare by:

• Ensuring procedural compliance. A tribunal that follows its own procedural rules, gives both parties equal opportunity to present their case, and issues a reasoned award is far less vulnerable to challenge.
• Documenting consent. Preserve all correspondence confirming the parties’ agreement to arbitrate, the appointment of arbitrators and the procedural timetable. This defeats allegations of lack of notice or due process.
• Addressing public policy proactively. If the underlying dispute touches on areas of regulatory sensitivity (e.g., foreign exchange, oil and gas licensing, anti-corruption), anticipate a public policy challenge and ensure the award addresses these issues with reasoned analysis.

Recognition of Mediated Settlement Agreements as Awards

The AMA permits a mediation settlement agreement to be recorded as a consent arbitral award or as a court consent order. This dual pathway gives mediated outcomes the same enforceability as arbitrated outcomes. The practical steps are: (a) upon reaching a settlement, request the mediator to document the terms in a written settlement agreement; (b) if the parties have an existing arbitration agreement or an ongoing arbitration, request the tribunal to record the settlement as a consent award; or (c) apply to the court for the settlement to be entered as a consent order. Either route converts the settlement into an enforceable instrument.

Mediation Under the New Framework: When to Require It and How to Secure Enforceable Settlements

The formal recognition of mediation under the AMA has transformed mediation law Nigeria 2026 from a voluntary, non-binding process into a commercially reliable dispute resolution mechanism. The key question for businesses is no longer whether mediation is enforceable, but when to require it and how to structure settlements for maximum legal certainty.

Enforceable Settlement Formats

Businesses have three options for ensuring a mediated settlement is enforceable:

• Consent arbitral award. If an arbitral tribunal is constituted (or if the mediation occurs within the framework of an arbitration), the settlement can be recorded as a consent award. This is the most robust option, as it carries the full force of an arbitral award and is enforceable under the AMA and the New York Convention.
• Court consent order. The parties can apply to a Nigerian court for the settlement to be entered as a consent order. This is appropriate where no arbitral tribunal is constituted and the parties want court-backed enforceability.
• Standalone settlement agreement. A mediation settlement agreement is contractually binding, but enforcement requires a separate breach-of-contract claim if a party defaults. This is the least efficient option and should be avoided for high-value disputes.

Multi-Tier Clause Drafting Examples

When drafting a multi-tier clause that includes a mediation step, specify: (a) the mediation rules or institution; (b) a time limit for the mediation phase; (c) a clear trigger for escalation to arbitration; and (d) whether the mediator may act as arbitrator (most institutional rules prohibit this to preserve neutrality). A well-drafted multi-tier clause under the current reforms can reduce overall dispute resolution costs while preserving the right to a binding, enforceable outcome.

Sector-Specific Considerations: Oil and Gas and Infrastructure

Oil and gas and infrastructure contracts present unique arbitration challenges in Nigeria, including multi-party structures, long project timelines, regulatory overlay and high-value claims. For businesses in these sectors, the Arbitration and Mediation Bill Nigeria 2026 reforms offer both opportunities and risks that require tailored clause design.

Three-point sector checklist:

• Emergency arbitrator provision. Include an express reference to emergency arbitrator procedures (available under ICC, LCA and other institutional rules) for urgent interim relief, such as preservation of assets, continuation of operations or prevention of irreversible harm, before the full tribunal is constituted.
• Security for costs. In upstream oil and gas disputes involving special purpose vehicles (SPVs) or thinly capitalised contractors, require the claimant to provide security for costs as a condition of proceeding with the arbitration.
• Seat selection. For joint ventures with Nigerian national oil company (NNOC) participation, a Nigerian seat is often commercially and politically appropriate. For international production-sharing or farm-in/farm-out agreements, consider whether a neutral seat (London, Paris) better serves enforcement needs across multiple jurisdictions while remaining enforceable in Nigeria under the New York Convention.

For further regulatory context on operations in this sector, see from exploration to decommissioning, regulatory compliance in Nigeria’s oil and gas lifecycle.

Conclusion

The Arbitration and Mediation Bill Nigeria 2026 reform cycle, encompassing the AMA and the National Arbitration Policy, has created a modernised, commercially credible framework for resolving disputes in and connected to Nigeria. The reforms reward proactive businesses: those that update their arbitration clauses now, embed enforceable multi-tier mechanisms, and prepare enforcement playbooks in advance will resolve disputes faster, at lower cost and with greater certainty of outcome. Those that continue to rely on outdated clause language or ad hoc procedures risk unenforceable awards, protracted court challenges and unnecessary commercial disruption.

The time to act is now, review every active contract, adopt the templates and checklists provided in this guide, and seek specialist advice where sector-specific or cross-border complexities demand a tailored approach.
