Commercial Arbitration Lawyers Nigeria, Drafting AMA Clauses, Interim Relief & Enforcement Risks

The Arbitration and Mediation Act 2023 (AMA 2023) replaced the decades-old Arbitration and Conciliation Act 1988, fundamentally reshaping how commercial arbitration lawyers in Nigeria draft dispute clauses, secure urgent interim measures, and enforce awards. With the 2026 National Arbitration Policy cycle prompting further administrative refinements, in-house counsel and contracts teams face a narrow window to update standard-form agreements before enforcement risk crystallises. This guide delivers six ready-to-use model clauses, a step-by-step interim relief workflow, and an enforcement checklist, the practical tools general counsel need to close deals confidently under the current statutory regime.

Why This Matters in 2026, Five Things Every GC Must Know

Nigeria’s arbitration landscape has shifted more in the last three years than in the previous three decades. The AMA 2023 introduced a modern statutory framework aligned with the UNCITRAL Model Law, and the 2026 reform cycle is layering on policy-level changes that affect institutional arbitration, emergency arbitrator availability, and the procedural mechanics of award enforcement. For any business with Nigerian counterparties, joint-venture partners, or assets, five issues now demand immediate attention:

• Clause compliance. Arbitration clauses drafted under the 1988 Act may lack the seat designation, emergency arbitrator opt-in, or interim relief language required to be fully effective under the AMA 2023.
• Interim relief access. The AMA 2023 creates a dual-track system, court-ordered interim measures and arbitral tribunal / emergency arbitrator interim measures, and knowing when to use each track can determine whether assets are preserved or dissipated before a hearing.
• Enforcement procedure. Awards are now enforced by originating notice of motion filed in court, and missteps in procedure or documentation remain the most common reason for delay.
• Tax and regulatory carve-outs. Disputes touching on fiscal obligations carry unique arbitrability risks; poorly drafted clauses may be struck down as contrary to public policy.
• Cost planning. Institutional arbitration costs in Nigeria scale with dispute value, and early budgeting prevents mid-arbitration funding crises.

The sections below address each of these issues with statutory references, model language, and practitioner checklists designed for immediate deployment.

Legal Framework, The Arbitration and Mediation Act 2023 and 2026 Reform Signals

Understanding the current law is the essential first step for any commercial arbitration matter in Nigeria. The AMA 2023 repealed and replaced the Arbitration and Conciliation Act 1988 (Cap A18 LFN 2004), modernising Nigerian arbitration law and bringing it substantially into line with the UNCITRAL Model Law on International Commercial Arbitration. The statute governs both domestic and international arbitration, codifies mediation for the first time, and establishes a clearer procedural pathway for interim relief, tribunal constitution, and award enforcement.

Timeline of Key Legislative and Policy Dates

The practical implications for in-house teams are threefold. First, the AMA 2023 makes the choice of seat, including Lagos as an increasingly favoured seat, a matter of genuine strategic consequence, because the procedural law of the seat now carries materially different interim relief and enforcement provisions compared with the 1988 Act. Second, the Act gives statutory backing to interim measures ordered by an arbitral tribunal, reducing the historical dependence on courts for urgent relief. Third, enforcement by originating motion on notice provides a streamlined court pathway, but one that demands precise compliance with documentation and procedural requirements.

Drafting an Enforceable Arbitration Clause Under the AMA 2023

An arbitration clause that would have been adequate under the 1988 Act may fail under the AMA 2023, or, worse, survive but create enforcement gaps that surface only after a dispute has arisen. Effective arbitration clause drafting in Nigeria now requires attention to eight essential elements and a deliberate choice among institutional and ad-hoc models.

Eight Must-Have Elements of an AMA-Compliant Clause

Every arbitration clause negotiated for a Nigerian-connected contract should address the following elements. Omitting any one can create grounds for challenge, delay enforcement, or leave a party without access to interim relief:

1. Clear identification of parties, including corporate affiliates, guarantors, or state entities that should be bound.
2. Scope of disputes, broad language covering disputes “arising out of or in connection with” the contract, rather than narrow formulations that risk excluding tort or restitutionary claims.
3. Seat of arbitration, specify the juridical seat (e.g., Lagos, Abuja) expressly; the seat determines the procedural law and the court with supervisory jurisdiction.
4. Applicable arbitration rules, name the institutional rules (e.g., ICC, LCIA, Lagos Court of Arbitration) or state that the arbitration shall be conducted ad hoc under the AMA 2023.
5. Appointing authority, designate who appoints the arbitrator(s) in default of party agreement to prevent deadlock.
6. Governing law of the contract, distinguish the governing law of the substantive agreement from the law of the arbitration (the seat).
7. Interim relief provision, expressly preserve the right to seek interim measures from both the tribunal and the courts under the AMA 2023, and opt in to emergency arbitrator procedures where the chosen institution offers them.
8. Waiver of sovereign immunity, where a state entity or state-owned enterprise is a party, include an express waiver of immunity from arbitration, from interim relief, and from enforcement of any award.

Model Clause Bank, Six Templates for Common Scenarios

The following model clauses are designed for copy-paste adaptation. Each includes a short commentary on enforcement risk and suitability. All clauses assume Nigerian law governs the contract unless otherwise stated.

Clause 1, Standard Ad Hoc (Domestic)

“Any dispute arising out of or in connection with this contract, including any question regarding its existence, validity, or termination, shall be referred to and finally resolved by arbitration under the Arbitration and Mediation Act 2023. The seat of arbitration shall be Lagos, Nigeria. The tribunal shall consist of a sole arbitrator appointed by agreement of the parties, or in default of agreement within 30 days, by the President of the Chartered Institute of Arbitrators (Nigeria Branch).”

Commentary: Suitable for mid-value domestic contracts. Low institutional costs, but parties bear the administrative burden of managing the process. Enforcement risk is low provided the clause is paired with an explicit interim relief reservation.

Clause 2, Institutional (ICC, Seat in Lagos)

“All disputes arising out of or in connection with the present contract shall be finally settled under the Rules of Arbitration of the International Chamber of Commerce by one or more arbitrators appointed in accordance with the said Rules. The seat of arbitration shall be Lagos, Nigeria. The language of the arbitration shall be English.”

Commentary: Gold-standard clause for high-value cross-border transactions. ICC administration reduces procedural risk. Industry observers note that specifying Lagos as the seat ensures Nigerian courts exercise supervisory jurisdiction under the AMA 2023, while the ICC framework provides familiar procedural guardrails for foreign counterparties.

Clause 3, Multi-Tier (Negotiation → Mediation → Arbitration)

“The parties shall first attempt to resolve any dispute by good-faith negotiation for 30 days. Failing resolution, the dispute shall be submitted to mediation under the AMA 2023 for a period not exceeding 60 days. Any dispute not resolved through mediation shall be referred to and finally resolved by arbitration administered by the Lagos Court of Arbitration under its Arbitration Rules. The seat shall be Lagos; the tribunal shall comprise three arbitrators.”

Commentary: Appropriate for long-term joint ventures and construction contracts where relationship preservation matters. The risk is that mandatory pre-arbitration steps become a ground for jurisdictional challenge if not strictly followed, ensure each tier has a defined time limit and clear trigger for escalation.

Clause 4, Emergency Arbitrator Opt-In

“The parties agree that the emergency arbitrator provisions of the [ICC/LCIA/LCA] Rules shall apply. Either party may apply for emergency interim relief before the constitution of the tribunal, and any order of the emergency arbitrator shall be binding.”

Commentary: Essential add-on for disputes where asset dissipation is a risk. Insert this as a supplementary paragraph within the main arbitration clause. Confirm that the chosen institution’s rules include emergency arbitrator provisions.

Clause 5, Tax Dispute Carve-Out

“Notwithstanding the foregoing, disputes relating exclusively to the determination, assessment, or collection of taxes, duties, or levies imposed under Nigerian fiscal legislation shall not be subject to this arbitration clause and shall be resolved through the statutory dispute resolution mechanisms prescribed by the applicable tax legislation. Disputes arising from the contractual allocation of tax liabilities between the parties, including indemnity obligations, shall remain subject to arbitration.”

Commentary: Navigating tax disputes arbitration in Nigeria requires precision. Clauses that purport to arbitrate the state’s taxing power risk being struck down on public-policy grounds. This carve-out preserves arbitrability for contractual tax-allocation disputes while respecting the statutory jurisdiction of tax tribunals.

Clause 6, Investor-State / State-Entity Clause with Immunity Waiver

“The [Government Entity] hereby irrevocably waives any right of sovereign immunity in respect of (a) the agreement to arbitrate, (b) any interim measures ordered by the tribunal or any court, and (c) the recognition and enforcement of any arbitral award, in any jurisdiction.”

Commentary: Without an express waiver, enforcement against state entities can stall. This clause should be incorporated alongside one of the substantive arbitration clauses above, although it is quite likely to be resisted by the government agency concerned. Early indications suggest Nigerian courts will give effect to such waivers where freely negotiated at arm’s length.

Drafting Notes for Tax and Regulatory Disputes

For now, tax disputes arbitration in Nigeria occupies a grey zone. The AMA 2023 does not expressly exclude tax disputes from its scope, but longstanding principles of Nigerian public law hold that the state’s taxing power is a sovereign function that cannot be submitted to private arbitration. The practical advice is to draft a clear boundary: arbitrate the contractual allocation of tax liabilities (indemnities, gross-up clauses, withholding obligations) but carve out challenges to the underlying tax assessment itself. Where a contract involves regulated sectors, oil and gas, telecommunications, power, confirm that the sector-specific legislation does not impose exclusive jurisdiction on a specialised tribunal, which would override the arbitration clause.

Interim Relief in Nigerian Arbitration, Emergency Arbitration vs Courts

Securing interim relief arbitration in Nigeria now follows a dual-track system under the AMA 2023. Either the arbitral tribunal (or an emergency arbitrator, if available under the chosen institutional rules) can order interim measures, or a party can apply directly to a Nigerian court. The two tracks are not mutually exclusive, the AMA 2023 permits court applications for interim measures even where an arbitration agreement exists, without that application being treated as a waiver of the right to arbitrate.

When to Approach a Court vs an Emergency Arbitrator, Decision Matrix

Practical Checklist for Securing and Enforcing Interim Relief Orders

1. Confirm your clause authorises interim measures, check both the arbitration clause and the applicable institutional rules for an emergency arbitrator opt-in.
2. Identify the correct court, under the AMA 2023, the High Court of the state where the seat is located, or where the asset or respondent is situated, has jurisdiction.
3. Prepare evidence of urgency, draft a supporting affidavit demonstrating risk of irreparable harm, asset dissipation, or destruction of evidence.
4. File promptly, delays undermine urgency arguments; file within days of discovering the threat.
5. Seek enforcement of tribunal-ordered measures through the court, interim measures ordered by an arbitral tribunal under the AMA 2023 are enforceable through the court in the same manner as a court order, but require a separate application for recognition.

Enforcement of Arbitral Awards in Nigeria and Setting-Aside Risks

The enforcement of arbitral awards in Nigeria under the AMA 2023 follows a streamlined but procedurally strict pathway. An arbitral award, whether domestic or foreign, is recognised and enforced by the court upon application. The practical mechanics and the grounds on which an opponent may resist enforcement are the two critical areas where commercial arbitration lawyers in Nigeria add the most value.

Step-by-Step Enforcement Checklist

1. Obtain the original award, secure a duly authenticated original award or a certified copy, together with the original arbitration agreement or a certified copy.
2. File an originating motion on notice, apply to the High Court of the relevant state (typically the seat or the location of the assets) by originating motion on notice, supported by an affidavit exhibiting the award and agreement.
3. Serve the respondent, effect service of the motion on the award debtor in accordance with the rules of court.
4. Attend the hearing, the court will hear any opposition (see setting-aside grounds below) and, if satisfied, enter the award as a judgment of the court.
5. Execute the judgment, once entered as a judgment, enforce using all standard execution methods: garnishee proceedings, attachment of assets, charging orders.

For foreign awards, Nigeria is a signatory to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958). The AMA 2023 gives domestic effect to Convention obligations, meaning a foreign award rendered in a Convention state is enforceable in Nigeria on the same basis as a domestic award, subject to the limited grounds for refusal mirroring Article V of the Convention.

Grounds for Setting Aside, Explanation and Mitigation Tips

A party seeking to resist enforcement or to set aside an award in Nigeria may rely on grounds closely aligned with the UNCITRAL Model Law and the New York Convention:

• Lack of jurisdiction. The tribunal exceeded its mandate or the arbitration agreement was invalid. Mitigation: draft a broad, unambiguous arbitration clause (see model clauses above) and raise jurisdictional objections at the earliest opportunity during the arbitration.
• Breach of natural justice. A party was not given proper notice of the proceedings or was unable to present its case. Mitigation: ensure meticulous procedural compliance, serve all notices, allow adequate time for submissions, and document every procedural step.
• Public policy. The award conflicts with Nigerian public policy. Mitigation: this is the most unpredictable ground; avoid awards that purport to override regulatory requirements, tax assessments, or criminal sanctions.
• Non-arbitrability. The subject matter of the dispute is not capable of settlement by arbitration under Nigerian law. Mitigation: confirm arbitrability before commencing proceedings, especially for disputes involving criminal conduct, matrimonial matters, or statutory regulatory functions.
• Procedural irregularity. The composition of the tribunal or the arbitral procedure was not in accordance with the parties’ agreement or the AMA 2023. Mitigation: follow the agreed rules and the Act scrupulously; document any deviations and the reasons for them.

Cross-Border Enforcement and the New York Convention

Nigeria’s accession to the New York Convention means that awards rendered in other Convention states enjoy a presumption of enforceability. The limited grounds for refusal mirror those for setting aside domestic awards. In practice, the most common challenge to foreign award enforcement in Nigeria has been the public-policy defence. The likely practical effect of the AMA 2023 is to narrow the scope of that defence over time, as Nigerian courts develop a body of case law interpreting the Act’s modernised provisions in line with international best practice.

Special Considerations, Tax Disputes, Public Contracts, and Arbitration Costs

Three areas require particular attention from in-house counsel structuring arbitration provisions for Nigerian transactions.

Tax disputes. As noted above, the intersection of arbitration and fiscal law is a drafting minefield. Contractual tax-allocation disputes (indemnities, gross-up clauses) are generally arbitrable, but challenges to the validity of a tax assessment issued by the Federal Inland Revenue Service or a state revenue authority should be directed to the Tax Appeal Tribunal and ultimately the courts. Clauses that blur this boundary risk a public-policy challenge at the enforcement stage.

Public contracts and state immunity. Arbitration clauses in contracts with Nigerian government ministries, departments, or agencies are enforceable in principle, but sovereign immunity can frustrate enforcement of the resulting award. An express, negotiated waiver of immunity, covering the agreement to arbitrate, interim measures, and enforcement, is essential (see Clause 6 above).

Arbitration Costs in Nigeria, Institutional Fee Ranges

These figures are indicative and exclude counsel fees, expert fees, hearing-room costs, and disbursements. Budget counsel fees at a minimum of 1.5 to 3 times the tribunal and administration fees combined for a contested arbitration. Early case assessment and realistic budgeting at the clause-drafting stage prevent mid-arbitration funding crises that compromise case strategy.

Practical Next Steps, A Law Firm Playbook for GCs

For general counsel reviewing or negotiating contracts with Nigerian arbitration provisions, the following action checklist provides a structured starting point:

1. Audit existing clauses. Review all current arbitration clauses in Nigerian-connected contracts against the eight must-have elements listed above. Flag any clause drafted under the 1988 Act for immediate updating.
2. Select the right institutional framework. Match the institution and rules to the deal size, counterparty sophistication, and likely enforcement jurisdiction. For cross-border deals over $5 million, institutional arbitration (ICC or LCIA with a Lagos seat) is generally preferred.
3. Negotiate interim relief provisions expressly. Do not rely on default rules, include an emergency arbitrator opt-in and an express reservation of the right to seek court-ordered interim measures.
4. Draft tax and regulatory carve-outs. For contracts in regulated sectors or with fiscal obligations, use Clause 5 (or a bespoke variant) to ring-fence non-arbitrable tax issues while preserving arbitrability for contractual allocation disputes.
5. Obtain sovereign immunity waivers. Where a government entity is a counterparty, negotiate Clause 6 language at the outset, it is far harder to obtain post-dispute.
6. Budget early. Use the costs table above to prepare a realistic arbitration budget at the contract-negotiation stage, and include cost-cap or fee-shifting provisions where appropriate.
7. Engage specialist arbitration counsel. For complex, high-value, or cross-border matters, early engagement of experienced commercial arbitration counsel in Nigeria ensures clause robustness, procedural compliance, and enforcement readiness.

Enforcement Checklist, Summary

1. Obtain authenticated original or certified copy of the award and arbitration agreement.
2. File originating motion on notice at the High Court of the seat or asset location.
3. Support the motion with a detailed affidavit exhibiting all required documents.
4. Serve the award debtor in accordance with court rules.
5. Attend the hearing and respond to any setting-aside application.
6. Upon entry as a judgment, execute via garnishee proceedings, asset attachment, or charging orders.

Engaging experienced commercial arbitration lawyers in Nigeria at the clause-drafting stage remains the single most effective way to reduce enforcement risk, control costs, and ensure that the dispute resolution mechanism actually works when it is needed. The AMA 2023 provides a robust statutory framework, but only clauses that are carefully drafted, interim relief strategies that are planned in advance, and enforcement steps that are procedurally precise will deliver the protection that businesses require.
