Commercial Arbitration in Nigeria: The Ultimate Business Guide (2026)

The Legal Framework: AMA 2023 and Nigeria’s Arbitration Architecture

The Arbitration and Mediation Act 2023 (AMA 2023) is the governing statute for all commercial arbitration in Nigeria. It was signed into law on 26 May 2023 and represents the most significant reform of Nigerian arbitration law in thirty-five years. The AMA 2023 repealed and replaced the Arbitration and Conciliation Act 1988 in its entirety.

The AMA 2023 is based on the UNCITRAL Model Law on International Commercial Arbitration (1985, as amended in 2006) — the same international framework adopted by leading arbitration jurisdictions including England, Singapore, and Hong Kong. This alignment with international standards was deliberate: it makes Nigerian arbitration awards more readily enforceable abroad and positions Nigeria as a credible seat for international disputes.

Nigeria has been a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards since March 1970 — one of the earliest African signatories. This means that arbitral awards rendered in Nigeria are enforceable in over 170 countries that have ratified the Convention, and foreign awards rendered in other Convention states are enforceable in Nigeria.

In July 2024, the Federal Executive Council formally launched Nigeria’s National Policy on Arbitration and Alternative Dispute Resolution — a strategic commitment to promote Nigeria as the preferred arbitration seat for African commercial disputes, strengthen institutional ADR infrastructure, and encourage the use of arbitration across both public and private sector contracts.

Why Nigerian Businesses Choose Arbitration Over Court Litigation

The choice between arbitration and litigation is not primarily about which process is more formal or more prestigious. It is about which process better serves the commercial interests of a business that needs a dispute resolved efficiently, confidentially, and with a final outcome that can actually be enforced.

Types of Arbitration Available in Nigeria

Ad-hoc arbitration

Ad-hoc arbitration is conducted without the involvement of an arbitral institution. The parties manage the process themselves — or with the assistance of their lawyers — appointing arbitrators directly, agreeing procedural rules, and handling administration. Ad-hoc arbitration can be more flexible and less expensive for smaller domestic disputes where both parties are cooperative. Its disadvantage is that without institutional administration, the process depends entirely on party cooperation — if one party becomes obstructive, delays are harder to manage.

Institutional arbitration

Institutional arbitration is administered by an established arbitral institution that provides procedural rules, a panel of arbitrators, administrative support, and enforcement of timelines. The institution charges administrative fees but provides significant procedural infrastructure — particularly valuable in complex disputes or where one party may be inclined to delay. The leading institutions relevant to Nigerian commercial disputes are described in the next section.

Domestic vs international arbitration

Domestic arbitration involves Nigerian parties resolving a Nigerian dispute under Nigerian law with Nigeria as the seat. International arbitration involves at least one foreign party or a dispute with significant cross-border elements — and may use a foreign seat, foreign governing law, and international institutional rules. The AMA 2023 governs both, with specific provisions for international commercial arbitration in Part III.

Arbitral Institutions: LCA, ICC, LCIA and Others

How Commercial Arbitration Works: The Step-by-Step Process

1. Dispute arises. A commercial dispute emerges from a contract, joint venture, shareholder agreement, or other commercial relationship. The contract contains an arbitration clause — or the parties agree to refer the dispute to arbitration after the dispute has arisen.
2. Notice of Arbitration served. The claimant serves a Notice of Arbitration on the respondent. The Notice must contain the names and addresses of the parties, the nature and circumstances of the dispute, and the relief or remedy claimed. Under AMA 2023, the arbitration commences on the date the Notice is received by the respondent.
3. Arbitral tribunal constituted. The parties appoint their arbitrators in accordance with the arbitration agreement — typically a sole arbitrator for smaller disputes or a three-member panel for larger ones. If parties cannot agree on an arbitrator, the appointing authority specified in the arbitration clause or the court makes the appointment.
4. Preliminary meeting and procedural directions. The tribunal holds a preliminary meeting to establish the procedural timetable: dates for exchange of statements of claim and defence, document production, witness evidence, and the hearing.
5. Pleadings and evidence exchange. Parties file their statements of claim and defence, exchange documentary evidence, and file witness statements. Expert evidence may be submitted for technical matters.
6. The hearing. The arbitral hearing takes place privately. Witnesses give evidence and are cross-examined. Both parties make submissions to the tribunal. The hearing may be conducted in person, by video conference, or in writing depending on the procedural agreement.
7. The award. The tribunal deliberates and issues its award — typically within 30 to 90 days of the close of the hearing. The award is in writing, signed by the arbitrators, and gives reasons for the decision. It is final and binding on the parties.
8. Enforcement. The winning party applies to the Federal High Court or relevant State High Court to enforce the award as a court judgment under Section 57 of the AMA 2023. Domestic awards are enforced with minimal grounds for resistance. New York Convention awards follow the procedure in Schedule 2 of the AMA 2023.

Key Innovations of the AMA 2023: What Changed for Nigerian Businesses

The AMA 2023 introduced several significant changes from the 1988 Act that directly affect how Nigerian businesses structure their dispute resolution and what remedies are available to them.

Emergency Arbitrators

For the first time in Nigerian arbitration law, the AMA 2023 introduced emergency arbitrator provisions. A party that needs urgent interim relief — an asset freeze, an injunction to stop a transaction, protection of evidence — can now apply for an emergency arbitrator without waiting for the full arbitral tribunal to be constituted. The LCA introduced its emergency arbitrator protocol in late 2024. This significantly reduces the need to run parallel court injunction proceedings alongside arbitration.

Third-Party Funding

The AMA 2023 explicitly permits third-party funding of arbitration proceedings in Nigeria for the first time. A party that cannot fund its own arbitration can now bring in a third-party funder — typically a specialist litigation funding company — who finances the claim in exchange for a share of the award. The funder must be disclosed to the tribunal and other parties. This opens Nigerian arbitration to claimants who previously could not afford to pursue meritorious claims.

Consolidation and Multi-Party Proceedings

The AMA 2023 introduced provisions allowing for the consolidation of related arbitrations and joinder of additional parties where the disputes are closely connected. This is particularly relevant for complex transactions — real estate developments, oil and gas joint ventures, and infrastructure projects — where multiple contracts and multiple parties are involved in a single underlying dispute.

Strengthened Pro-Arbitration Judicial Stance

The AMA 2023 codifies and strengthens Nigeria’s pro-arbitration judicial policy. Courts are now explicitly required to refer parties to arbitration when a valid arbitration agreement exists, and the grounds on which courts may intervene in arbitration proceedings are strictly limited. The Supreme Court’s 2024 decisions have reinforced this stance — Nigerian courts are increasingly reluctant to interfere with arbitration proceedings or awards except on the narrow statutory grounds.

Mediation as a Distinct Track

The AMA 2023 for the first time regulates mediation as a distinct and structured process separate from arbitration — not merely as a precursor to litigation. The Act implements the Singapore Convention on Mediation, allowing mediated settlement agreements to be enforced in signatory states in a similar manner to arbitral awards.

Sector-by-Sector: When Arbitration Is the Right Choice

Costs and Timeline: What to Budget for Nigerian Arbitration

Cost is one of the most common concerns raised by Nigerian businesses considering arbitration. The honest answer is that arbitration is not cheap — but it is significantly less expensive than multi-year court litigation when the total cost (legal fees plus management time plus business disruption) is calculated.

Domestic arbitration costs

A straightforward domestic commercial arbitration before a sole arbitrator at the LCA — involving a dispute in the range of ₦50 million to ₦500 million — will typically involve arbitrator fees, LCA administrative fees, legal representation costs, and expert fees where relevant. Total costs for a reasonably straightforward domestic arbitration are generally in the range of 5% to 15% of the amount in dispute, depending on complexity. Timeline: typically six to nine months from Notice of Arbitration to award.

International arbitration costs

International arbitration before the ICC or LCIA is significantly more expensive — reflecting the complexity of the disputes, the calibre of arbitrators, and the administrative infrastructure of the institution. For cross-border disputes, total costs (including legal representation on both sides) commonly reach 15% to 30% of the amount in dispute. Timeline: typically twelve to twenty-four months for complex international disputes.

Enforcing Arbitral Awards in Nigeria

An arbitral award — whether domestic or foreign — must be enforced through the Nigerian court system to become executable. The AMA 2023 sets out the enforcement regime.

Domestic awards

A domestic arbitral award is enforced by application to the Federal High Court or the relevant State High Court under Section 57 of the AMA 2023. The court grants leave to enforce the award as a judgment of the court unless the respondent demonstrates one of the limited grounds for refusal — which do not include a general right of appeal on the merits. Once enforced, the award is treated as a court judgment and all enforcement mechanisms available to judgment creditors (attachment of assets, garnishee orders, etc.) become available.

Foreign awards (New York Convention)

Foreign arbitral awards from New York Convention states are enforced in Nigeria under Schedule 2 of the AMA 2023. The applicant files the original or certified copy of the award, the original or certified copy of the arbitration agreement, and a certified translation if the award is in a language other than English. The court recognises and enforces the award unless one of the Convention’s limited grounds for refusal applies.

Drafting an Effective Arbitration Clause

The arbitration clause in a commercial contract determines whether arbitration will be available, efficient, and enforceable when a dispute arises. A poorly drafted clause can invalidate the entire arbitration agreement — or create satellite litigation about the clause itself that delays the actual dispute resolution by months or years.

An effective Nigerian arbitration clause under the AMA 2023 must contain:

• A clear agreement to arbitrate. The clause must unambiguously submit future disputes to arbitration — not merely express an intention to consider arbitration. Language like “disputes may be referred to arbitration” is permissive, not mandatory, and may not be enforceable.
• Designation of the seat of arbitration. The seat determines which national law governs the arbitration procedure. For most Nigerian domestic disputes, Lagos is the appropriate seat. For international disputes, Lagos, London, or Singapore are common choices.
• Number of arbitrators. Specify whether disputes will be decided by a sole arbitrator or a three-member panel. Sole arbitrators are faster and less expensive; panels provide more procedural protection in high-value disputes.
• Appointing authority. Specify who appoints the arbitrator(s) if the parties cannot agree — typically the LCA, the ICC, or the CIArb Nigeria Branch for domestic disputes.
• Governing law. Specify the law that governs the substantive rights and obligations of the parties — typically Nigerian law for domestic contracts.
• Language. Specify the language of the arbitration — typically English for Nigerian commercial disputes.

Common Mistakes That Undermine Nigerian Arbitration

• Signing a contract with no arbitration clause. Once a dispute has arisen, persuading the other side to agree to arbitration — when they know they can simply wait out years of court proceedings — is extremely difficult. The arbitration clause must be in the contract before the relationship begins.
• Using a pathological arbitration clause. Clauses that do not clearly identify the seat, the appointing authority, or the number of arbitrators generate satellite litigation before the substantive dispute even begins. “All disputes shall be resolved by arbitration” with nothing else is a pathological clause — it raises more questions than it answers.
• Choosing an institutional clause without reading the institution’s rules. Parties who specify “ICC arbitration” without understanding that ICC arbitration typically costs significantly more than LCA arbitration — and takes significantly longer for straightforward domestic disputes — are not making an informed choice.
• Ignoring the arbitration clause when a dispute arises and going straight to court. A party that commences court proceedings in breach of a valid arbitration agreement will find those proceedings stayed by the court on the respondent’s application under Section 5 of the AMA 2023. The result is wasted legal fees and delay — not a shortcut to resolution.
• Failing to meet time limits for challenging an award. Under the AMA 2023, an application to set aside an award must be made within three months of receipt of the award. Missing this deadline means the losing party loses the right to challenge the award on any ground — including genuine procedural irregularity. Time limits in arbitration are strict and courts will not extend them without compelling justification.
