Enforcing Arbitral Awards Against Government & State‑owned Parties in Nigeria: Practical Guide for Investors

Enforcing an arbitral award against a Nigerian government ministry, department or agency (MDA), or a state-owned enterprise (SOE), raises issues that are not always encountered in private commercial disputes. While the Arbitration and Mediation Act 2023 (AMA 2023) modernised Nigeria’s arbitral framework and aligned it more closely with the UNCITRAL Model Law, parties seeking to enforce awards against public entities must also consider questions of sovereign immunity, public finance procedures and the practical realities of execution.

The introduction of the National Arbitration Policy 2024 also reflects the Federal Government’s commitment to greater use of arbitration in public contracts and encourages government entities to adopt arbitration clauses while discouraging unnecessary reliance on sovereign immunity. Although the policy does not eliminate the legal and procedural hurdles that may arise during enforcement, it provides useful context for parties dealing with Nigerian public bodies.

This article examines the practical considerations involved in enforcing arbitral awards against government entities in Nigeria and outlines the steps investors and their advisers should take when deciding whether to pursue enforcement, negotiate settlement, or adopt a combination of both approaches.

Executive Summary

Nigerian law permits the enforcement of both domestic and foreign arbitral awards against government ministries, departments and agencies (MDAs), as well as state-owned enterprises (SOEs), provided the requirements of the Arbitration and Mediation Act 2023 (AMA 2023) and any applicable enforcement regime are satisfied. In practice, however, obtaining recognition of an award is often only one part of the process. Questions relating to sovereign immunity, the nature of the respondent’s assets and the applicable enforcement procedure frequently determine whether an award can be realised.

Before commencing enforcement proceedings, an award creditor should consider three preliminary issues. First, the applicable enforcement regime must be identified. The procedure will differ depending on whether the award is a domestic award, a foreign award enforceable under the New York Convention, or an ICSID award. Secondly, consideration should be given to whether the respondent owns commercial assets against which execution may realistically be levied. Finally, it is important to determine whether sovereign immunity has been waived contractually or whether the facts support reliance on the commercial transaction exception recognised under Nigerian law and international practice.

The AMA 2023 has strengthened Nigeria’s enforcement framework by modernising the recognition and enforcement regime and limiting the circumstances in which Nigerian courts may refuse enforcement of arbitral awards. The National Arbitration Policy 2024–2028 further reflects the Federal Government’s commitment to arbitration in public contracting and encourages public bodies to honour their arbitration agreements. While these developments are expected to improve the enforcement landscape, they do not remove the practical and procedural challenges that often arise when enforcing awards against public entities. Accordingly, investors should consider enforcement proceedings and settlement discussions as complementary strategies rather than mutually exclusive options.

Legal Framework: The AMA 2023, New York Convention and ICSID 

Key AMA 2023 Provisions That Matter

The Arbitration and Mediation Act 2023 contains the core provisions governing the arbitration award enforcement process in Nigeria. Part IV of the Act addresses recognition and enforcement: an arbitral award shall, irrespective of the country in which it was made, be recognised as binding and enforced on application to the court. Section 57 sets out the documents an applicant must file, the authenticated original award (or certified copy) and the arbitration agreement. Section 58 lists the exhaustive grounds on which a court may refuse recognition or enforcement, mirroring Article V of the New York Convention.

Separately, Section 55 provides that a court may set aside a domestic award only on narrow grounds such as incapacity, lack of notice, or conflict with Nigerian public policy.

Recognition and Enforcement under the AMA 2023

The Arbitration and Mediation Act 2023 (AMA 2023) provides the principal legal framework for the recognition and enforcement of arbitral awards in Nigeria. Part IV of the Act provides that an arbitral award, irrespective of the country in which it was made, is binding and may be recognised and enforced upon application to the court, subject to the provisions of the Act.

Under section 57, an applicant seeking recognition or enforcement must produce the duly authenticated original award, or a certified copy, together with the original arbitration agreement or a duly certified copy. Section 58 sets out the limited grounds upon which a Nigerian court may refuse recognition or enforcement. These grounds substantially reflect Article V of the New York Convention and are intended to ensure that judicial intervention remains exceptional rather than routine.

In relation to domestic awards, section 55 limits the circumstances in which an award may be set aside. These include, among other grounds, incapacity of a party, lack of proper notice, procedural irregularity and conflict with the public policy of Nigeria. The narrow scope of these grounds reinforces the Act’s pro-enforcement approach and supports the finality of arbitral awards.

Nigeria and the New York Convention

Nigeria is a Contracting State to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards 1958 (New York Convention) and has adopted the reciprocity reservation. Accordingly, the Convention applies only to arbitral awards made in the territory of another Contracting State.

For parties seeking to enforce a foreign arbitral award in Nigeria, it is therefore important to confirm whether the seat of arbitration is in a Contracting State. Where the Convention does not apply, enforcement may instead be pursued under the relevant provisions of the Arbitration and Mediation Act 2023 or, where applicable, the common law.

ICSID Awards and Domestic Enforcement

Nigeria is also a Contracting State to the Convention on the Settlement of Investment Disputes between States and Nationals of Other States (ICSID Convention). Article 54 of the Convention requires each Contracting State to recognise an ICSID award as binding and to enforce the pecuniary obligations imposed by the award as though it were a final judgment of its own courts.

Accordingly, an award creditor seeking to enforce an ICSID award in Nigeria may present a certified copy of the award for recognition and enforcement before the appropriate Nigerian court. Unlike awards enforced under the New York Convention, an ICSID award is not subject to review on its merits by the enforcing court. The court’s role is limited to recognising and enforcing the award in accordance with the Convention.

It should be noted, however, that recognition of an ICSID award is distinct from execution against state assets. The ICSID Convention does not remove the protections afforded by the law of state immunity. As a result, while an ICSID award may be recognised, the successful party may still encounter restrictions when seeking to execute against assets belonging to a sovereign state or its agencies.

Enforcement: Government, MDAs & SOEs, Legal Tests

Distinguishing a Government Body From an SOE

Not every public‑sector counterparty enjoys the same level of protection. A core government ministry, department, or agency (MDA), established by statute and funded from the Consolidated Revenue Fund, will typically assert full sovereign immunity. A state‑owned enterprise (SOE) that operates as a commercial entity, holds its own assets, and earns revenue from market transactions occupies a different position. Nigerian courts apply a functional test: the question is whether the entity was acting in a sovereign (jure imperii) or commercial (jure gestionis) capacity when it entered the contract giving rise to the dispute. Practitioners should gather the SOE’s enabling statute, board composition, and financial statements to establish its commercial character.

State Immunity Doctrine Under Nigerian Law

State immunity in Nigeria draws from common‑law principles and the constitutional protections afforded to government assets. The general rule is that the property of a state or its agency cannot be attached or executed upon in satisfaction of a judgment or award. However, Nigerian courts have recognised the commercial‑activity exception: where a government entity enters into a purely commercial transaction, it may be treated as having implicitly waived its immunity from enforcement. Leading appellate decisions confirm that entering an arbitration agreement in a commercial context can itself constitute a submission to the jurisdiction, which extends to enforcement proceedings. Practitioners seeking to enforce an award against a government entity must be prepared to demonstrate the commercial nature of the underlying transaction.

Practical Evidence to Overcome Immunity

Beating an immunity defence requires proactive evidence‑gathering, ideally starting before the arbitration concludes. Key documents include the contract itself (demonstrating commercial terms), corporate‑registry filings for SOEs, audited financial statements showing revenue from commercial operations, and any express waiver‑of‑immunity clauses in the contract. Where the contract contains a clause stating that the government party waives immunity from enforcement and execution, Nigerian courts have generally upheld that waiver. Asset‑tracing should begin early: identify commercial bank accounts, receivables under third‑party contracts, real property held in the SOE’s name, and moveable assets. The strongest enforcement applications present the court with a clear map linking the award quantum to specific attachable assets.

Enforcement Routes 

The appropriate enforcement route depends primarily on the nature of the award. An award creditor should first determine whether the award is a domestic award, a foreign award enforceable under the New York Convention, or an ICSID award, as the applicable procedure differs in each case.

Quick Assessment Checklist (Pre‑Litigation)

Before filing any application, run through this pre‑litigation checklist:

1. Award type: Domestic, foreign (New York Convention), or ICSID?
2. Jurisdiction: Which court has subject‑matter and territorial jurisdiction?
3. Assets: Has the counterparty’s attachable property been identified and located?
4. Immunity risk: Is the respondent an MDA or a commercial SOE? Does a contractual waiver exist?
5. Limitation: Is the application within time? The AMA 2023 does not prescribe a specific limitation period for enforcement, but general limitation statutes apply.
6. Cost‑benefit: Do estimated enforcement costs justify the award quantum?

Domestic Award Enforcement

A domestic arbitral award is ordinarily enforced by application to the High Court with jurisdiction over the respondent or its assets. The application is supported by affidavit evidence exhibiting the award and the arbitration agreement.

The court does not reconsider the merits of the dispute. Its function is limited to determining whether any of the statutory grounds for refusing recognition or enforcement under the Arbitration and Mediation Act 2023 has been established. Where no such ground is made out, the award may be recognised and enforced as a judgment of the court, after which ordinary execution procedures become available.

Recognition of Foreign Arbitral Awards

Foreign arbitral awards made in New York Convention Contracting States are enforceable in Nigeria upon production of the authenticated award, the arbitration agreement, and any required certified translation. The grounds for refusal are limited to those set out in section 58 of the Arbitration and Mediation Act 2023, which substantially reflects Article V of the New York Convention.

Because Nigeria applies the Convention on the basis of reciprocity, it is important to confirm that the award was made in the territory of a Contracting State. Where that requirement is not satisfied, enforcement may need to proceed under other applicable legal principles.

ICSID Awards

ICSID awards are subject to a distinct enforcement regime under the ICSID Convention. A certified copy of the award may be presented to the appropriate Nigerian court for recognition and enforcement. The enforcing court does not review the merits of the award, and the Convention requires the pecuniary obligations imposed by the award to be treated as though they were contained in a final judgment of the court.

Recognition of an ICSID award does not, however, guarantee successful execution against state assets. Questions of execution remain subject to the applicable rules of state immunity and domestic law.

Interim Measures & Injunctions Against MDAs/SOEs

Where there is a real risk that asset may be dissipated  before enforcement can be completed, an award creditor may seek interim relief from the arbitral tribunal or the court. The Arbitration and Mediation Act 2023 expressly empowers both the tribunal and the court to grant interim measures, including preservation orders and injunctions. Against MDAs and SOEs, practitioners commonly seek Mareva‑style freezing orders over commercial bank accounts and receivables. However, courts will scrutinise whether the targeted assets are sovereign in character; assets held for public or governmental purposes are generally immune from attachment.

An application for interim relief should ordinarily be supported by affidavit evidence addressing the urgency of the application, the risk of dissipation, the assets sought to be preserved, and the applicant’s underlying entitlement under the award. The applicant may also be required to provide an undertaking as to damages.

The availability and scope of interim relief will depend on the facts of the case, the nature of the assets identified, and the applicable procedural rules.

A recommended pleadings checklist for interim relief includes:

• Motion ex parte or on notice, with supporting affidavit deposing to urgency and risk of dissipation.
• Draft order, specifying the assets to be frozen, the quantum, and the duration.
• Undertaking as to damages, the applicant must offer a cross‑undertaking.
• Evidence of asset location, bank statements, contract receivables, or real‑property records.
• Proof of the underlying award, to demonstrate the applicant’s substantive entitlement.

Indicative timelines:

1. Domestic award (uncontested): approximately 3–6 months from filing to judgment entry.
2. Domestic award (contested by MDA/SOE): approximately 6-18 months, including potential appeal.
3. Foreign award (NY Convention): approximately 6–24 months, depending on documentary challenges.
4. ICSID award (certification in hand): approximately 3–12 months for recognition and registration

Actual timelines may be shorter or longer depending on the court’s docket, the complexity of the objections raised, service issues, interlocutory applications, and appellate proceedings. Investors should therefore treat these ranges as indicative estimates rather than predictions of outcome.

Court Practice Notes, Local Tactics & Filing Templates

Typical Court Venues and Practice

Venue selection is a tactical decision. The Federal High Court has exclusive jurisdiction over matters involving the federal government, its agencies, and entities established by federal statute. For SOEs incorporated under the Companies and Allied Matters Act, the State High Court in the state where the SOE’s assets or head office is located may also have jurisdiction. In the Federal Capital Territory (FCT), the FCT High Court has issued a dedicated Practice Direction for its Enforcement Unit, which prescribes standardised procedures and timelines for enforcement applications, making Abuja a potentially efficient venue for enforcement of awards in Nigeria.

Common Procedural Hurdles

In enforcement proceedings against government entities and state-owned enterprises, respondents frequently raise procedural objections before addressing the substance of the application. Common objections include challenges to service, applications for a stay pending appeal, and arguments based on public policy or sovereign immunity.

These issues are often best addressed proactively. Service should be effected strictly in accordance with the applicable procedural rules and, where appropriate, on the relevant public officer or authorised representative of the entity concerned. Where sovereign immunity may be raised, the supporting affidavit should identify the commercial nature of the underlying transaction and exhibit any contractual waiver of immunity.

Careful preparation of the application and supporting evidence at the outset may reduce the likelihood of avoidable adjournments and interlocutory applications.

Supporting Documents

An application for recognition and enforcement will ordinarily be supported by the following documents:

• The authenticated original or certified copy of the arbitral award.
• The original or certified copy of the arbitration agreement (or the relevant contractual clause).
• Certificate or proof of service of the award on the respondent.
• A certified English translation (if the award or agreement is in another language).
• Evidence of the respondent’s assets, bank account details, property deeds, contract receivables.
•  Corporate registry search confirming the respondent’s legal status and registered address.
• Any contractual waiver‑of‑immunity clause (highlighted and indexed).

The precise documentary requirements will depend on the nature of the award and the court before which enforcement is sough

Sample Affidavit Statement

The following wording is illustrative only and should be adapted to the facts of the particular case:

 “I, [Name], being the duly authorised representative of the Applicant, make oath and state that the arbitral award dated [Date] was duly made by [Tribunal] in accordance with the arbitration agreement between the parties dated [Date]. The award has not been set aside or suspended, and no grounds for refusal under Section 58 of the Arbitration and Mediation Act 2023 apply. The Respondent has failed and/or refused to comply with the award despite service.”

Assets, Enforcement Mechanics & Cross‑Border Remedies

Identifying Attachable Assets

Successful enforcement turns on asset identification. SOEs engaged in commercial operations typically maintain naira and foreign‑currency accounts at commercial banks, hold receivables under supply or service contracts with private‑sector counterparties, and own real property (offices, warehouses, industrial facilities). These commercial assets are generally attachable. By contrast, assets held in trust for the government, funds in the Consolidated Revenue Fund, and property devoted to sovereign functions (embassies, military installations) are immune. Practitioners should commission an asset‑tracing exercise, using corporate‑registry searches, land‑registry inquiries, and, where available, disclosure orders, before filing the enforcement application.

Using Interlocutory Remedies for Preservation

Freezing orders and orders for disclosure are the primary tools for preserving assets during enforcement proceedings. A freezing order prevents the respondent from dissipating specified assets up to the value of the award. The applicant must demonstrate a good arguable case on the merits (the award itself usually satisfies this) and a real risk of dissipation. Against MDAs, courts are cautious; the likelihood of a government ministry dissipating assets is lower, but SOEs facing financial distress may actively move funds or restructure holdings. Where the court grants a freezing order, it will typically require the applicant to give a cross‑undertaking in damages.

Mutual Assistance, Letters Rogatory & Foreign Enforcement

If the respondent’s assets are located outside Nigeria, the award‑holder may need to seek recognition and enforcement in the relevant foreign jurisdiction, either under the New York Convention or through bilateral treaties. Coordinating parallel proceedings in Nigeria and abroad is a common strategy for maximising recovery. Letters rogatory can be used to request foreign courts to assist with evidence‑gathering or asset disclosure. Where the respondent is an SOE with international operations, identifying offshore assets (bank accounts in London, Dubai, or New York) and commencing enforcement in those jurisdictions creates additional settlement pressure.

Settlement or Enforcement?

An arbitral award against a government entity or state-owned enterprise should not automatically proceed to full enforcement proceedings. In many cases, the more effective strategy is to commence enforcement proceedings while keeping settlement discussions open. The commencement of proceedings may create commercial and reputational pressure on the respondent, while negotiations may produce a faster and less costly recovery.

The choice between enforcement, settlement and a parallel approach will depend on the value of the award, the availability of attachable assets, the respondent’s willingness to engage, and the investor’s broader commercial objectives.

Decision triggers for each approach: Choose full enforcement when the respondent refuses to engage, assets are clearly identifiable, and the award quantum justifies the cost. Choose settlement when the counterparty signals willingness, ongoing commercial interests exist, or sovereign‑immunity risk is high. Choose the hybrid approach, which industry observers consider the most effective against MDAs and SOEs, when you want maximum leverage with a fallback position.

Drafting Considerations for Investors

The prospects of enforcing an arbitral award against a public counterparty are often influenced by the quality of the underlying contract. Investors negotiating contracts with Nigerian government entities or SOEs should consider the following protections:

1. An arbitration clause identifying the seat of arbitration and the applicable institutional rules.
2. A clear governing law clause.

3. An express waiver of sovereign immunity from suit, enforcement and execution to the extent permitted by law.
4. A submission to the jurisdiction of courts competent to recognise and enforce the award.
5. A provision preserving the parties’ right to seek interim or conservatory relief from courts or emergency arbitrators.
6. Appropriate security arrangements, such as escrow mechanisms, bank guarantees or standby letters of credit, where commercially feasible.
7. Provisions dealing with assignment of contractual and enforcement rights where financing or award monetisation may be contemplated.
8. Cost and interest provisions specifying the recovery of reasonable legal costs and post-award interest.

Sample Waiver clause: 

The following clause is illustrative only and should be adapted to the governing law and the particular transaction:

“The [Government Party] irrevocably and unconditionally waives any immunity (sovereign or otherwise) from suit, jurisdiction, enforcement, attachment, and execution to which it might otherwise be entitled in any legal proceedings arising out of or in connection with this Agreement, including enforcement of any arbitral award.waives any immunity (sovereign or otherwise) from suit, jurisdiction, enforcement, attachment, and execution to which it might otherwise be entitled in any legal proceedings arising out of or in connection with this Agreement, including enforcement of any arbitral award.”

Timelines, Costs & Probabilities

Enforcement costs vary widely depending on the respondent’s posture, the complexity of immunity issues, and whether cross‑border proceedings are necessary. The table below offers indicative ranges.

Factors that push costs up: appeals by the government respondent, contested immunity applications, need for asset‑tracing across multiple jurisdictions, translation and authentication of foreign‑language awards, and parallel proceedings abroad. Early, thorough asset‑tracing and a well‑prepared initial filing can significantly reduce downstream costs.

Conclusion & Recommended Next Steps

The Arbitration and Mediation Act 2023 has strengthened Nigeria’s framework for the recognition and enforcement of arbitral awards, and the National Arbitration Policy signals a broader institutional commitment to arbitration in public contracting. These developments improve the legal environment for award creditors. Nevertheless, enforcement against government entities and state-owned enterprises remains highly fact-sensitive, particularly where sovereign immunity and execution against public assets are concerned.

Before commencing enforcement proceedings, investors should identify the applicable enforcement regime, assess the availability of commercial assets, and evaluate any immunity issues arising under the contract or applicable law. Where attachable assets have been identified and the value of the award justifies the cost, prompt enforcement action may be appropriate. Where immunity concerns are significant or a continuing commercial relationship exists, a negotiated resolution may offer a more efficient route to recovery.

In practice, enforcement proceedings and settlement discussions are often pursued in parallel. Commencing enforcement preserves the award creditor’s legal position and may encourage meaningful negotiations, while settlement discussions may achieve recovery without prolonged execution proceedings.
