Ship Arrest vs Arbitration in Nigeria (2023–2026): When to Arrest a Vessel and When to Pursue Arbitration

When a maritime dispute arises in or touching Nigeria, the central strategic question is ship arrest vs arbitration Nigeria, do you arrest the vessel now to secure your claim, or do you pursue arbitration and rely on later enforcement? The answer has shifted materially since the Admiralty Jurisdiction Procedure Rules (AJPR) 2023 expanded the Federal High Court’s power to arrest vessels as security for foreign courts and arbitral proceedings, and shifted again following a February 2026 Federal High Court development that, according to practitioner alerts, narrowed the enforceability of certain foreign arbitral awards in maritime claims.

This article delivers what no existing guide on the SERP provides: a dimension-by-dimension comparison, a costed decision framework, and a concrete checklist so that shipowners, charterers, cargo interests, P&I clubs, and in-house counsel can make the call, and instruct local counsel, within hours of a triggering event.

Option A: Ship Arrest (In Rem), What It Is, When It Applies, Who It Suits

Ship arrest is an in-rem proceeding under the Admiralty Jurisdiction Act 1991 (AJA) and, since late 2023, the Admiralty Jurisdiction Procedure Rules 2023 (AJPR 2023). The claimant obtains a court order directing the arrest and physical detention of a vessel in a Nigerian port to preserve security for a maritime judgment or award. The claim is brought against the ship itself, not its owner personally, which means the vessel is the primary asset against which the claimant recovers.

Qualifying maritime claims

Not every commercial dispute qualifies. The AJA defines “Maritime Claim” to include, among others:

• Collision or damage caused by a ship.
• Salvage.
• Crew wages and master’s disbursements.
• Ship mortgage or charge.
• Cargo loss or damage.
• Unpaid bunkers, necessaries, or towage.
• Possession or ownership disputes.
• Charterparty disputes (where the claim is a maritime claim within the AJA list).

If the claim does not fall within the statutory list, the Federal High Court will decline in-rem jurisdiction and the arrest application will fail.

Who ship arrest suits

Arrest is the correct first move for claimants who need immediate security, bunker suppliers owed large sums, cargo receivers facing uncompensated loss, or any party that suspects the shipowner may be unable or unwilling to satisfy a future award. It is also the preferred route where the vessel is in or about to call at a Nigerian port and may not return, giving the claimant a narrow window to detain her.

Can I arrest a ship in Nigeria to secure an arbitration claim?

Yes. The AJPR 2023 introduced express procedural provisions enabling arrest of a vessel to provide security for proceedings in foreign courts and arbitrations. Before these rules, Nigerian admiralty practice was less certain on this point. The position is now explicit: a claimant with an existing or intended arbitration may apply to the Federal High Court for an arrest order specifically to obtain security for that arbitral proceeding, provided the underlying claim qualifies as a maritime claim under the AJA.

Procedural timeline

A typical arrest proceeds as follows: the claimant files a writ in rem at the Federal High Court, supported by an affidavit setting out the nature and quantum of the maritime claim; the court issues a warrant of arrest; the Admiralty Marshal (or sheriff) executes the arrest at the port where the vessel is berthed. If the vessel is in port and the procedural requirements are in order, the entire process can be completed within days. The shipowner or P&I club may then apply to substitute security, commonly a bank guarantee or P&I club letter of undertaking (LOU), after which the vessel is released and resumes trading.

Option B: Arbitration (and Security Mechanisms), What It Is, When It Applies, Who It Suits

Arbitration is the contractually agreed mechanism for resolving the underlying dispute on its merits. Most charterparties, bills of lading incorporating charterparty terms, and international supply contracts contain arbitration clauses, typically specifying a foreign seat such as London (LMAA rules), Singapore (SIAC), or Paris (ICC). An arbitral tribunal hears evidence, applies the governing law, and renders a final, binding award.

Security within arbitration

Arbitration’s principal weakness, relative to arrest, is that the tribunal itself has limited power to seize assets. Interim security within arbitration can take several forms:

• Tribunal-ordered interim measures, most institutional rules (ICC, LCIA, SIAC) empower the tribunal to order preservation of assets, but enforcement depends on the respondent’s cooperation or a national court’s assistance.
• Emergency arbitrator relief, available under ICC, SIAC, and LCIA rules before the tribunal is constituted, but again relies on voluntary compliance or judicial support.
• Letters of undertaking (LOUs), negotiated between P&I clubs; common in shipping but dependent on the respondent’s willingness.
• National court assistance, post-AJPR 2023, a claimant in a foreign arbitration may apply to the Nigerian Federal High Court for arrest as security, effectively bridging the gap between arbitration and local in-rem security.

When arbitration is preferable

Arbitration is the stronger path in several clear scenarios:

• The contract mandates it. Ignoring a valid arbitration clause risks having Nigerian court proceedings stayed under the Arbitration and Mediation Act 2023.
• Confidentiality matters. Court proceedings in Nigeria are public; arbitration proceedings are private.
• Specialist expertise is needed. Complex charterparty or laytime/demurrage disputes benefit from maritime arbitrators rather than generalist judges.
• Cross-border enforcement is reliable. Nigeria is a signatory to the New York Convention, so foreign arbitral awards are in principle enforceable, though the February 2026 Federal High Court development, discussed below, introduces a caveat for certain maritime awards.

The timeline from filing a request for arbitration to a final award is typically measured in months to over a year for institutional arbitration, and can extend further in ad hoc proceedings. Enforcement in Nigeria may add additional months.

Ship Arrest vs Arbitration in Nigeria: Side-by-Side Comparison

The table above frames the core trade-offs in the ship arrest vs arbitration decision. The sections below unpack each dimension with the practical detail claimants and respondents need.

Dimension-by-Dimension Analysis

Eligibility and legal basis (AJA 1991 / AJPR 2023)

The threshold question is whether the claim qualifies as a “Maritime Claim” under the Admiralty Jurisdiction Act 1991. If it does, the Federal High Court has in-rem jurisdiction, and arrest is available. The AJA lists over twenty categories of maritime claim, covering the vast majority of commercial shipping disputes. The AJPR 2023 expanded the procedural scope by permitting the Federal High Court to arrest vessels as security for proceedings before foreign courts and foreign or domestic arbitral tribunals. This means that even where the parties have agreed to London arbitration, the claimant can apply for arrest in Nigeria to secure the anticipated award, a power that was uncertain before 2023.

Documents typically required for an arrest application include:

• Writ of summons in rem.
• Affidavit verifying the nature, quantum, and maritime character of the claim.
• Evidence of the vessel’s presence or expected arrival in Nigerian waters.
• Any relevant contractual documents (charterparty, bill of lading, bunker supply contract).

Cost and financial exposure

The cost structures of arrest and arbitration differ sharply in timing and distribution. Arrest frontloads costs but secures assets immediately; arbitration spreads costs over months but may leave the claimant unsecured until enforcement.

For claimants, the critical insight is that the arrest is cheap relative to the alternative risk of having no security at all. For shipowners, the commercial cost of prolonged detention means prompt substitution of security is almost always the rational response.

Timing and speed to security

Speed is arrest’s greatest advantage. Where the vessel is in a Nigerian port and the application is properly prepared, the Federal High Court can issue an arrest warrant within days, sometimes on the same day the application is heard. The Admiralty Marshal executes the warrant at the port, and the vessel is detained until security is provided or the claim is resolved.

Arbitration operates on a fundamentally different timeline. Constituting a tribunal takes weeks (often four to eight weeks under institutional rules). Emergency arbitrator procedures are faster but produce orders that depend on voluntary compliance or court enforcement. A final award, the point at which the claimant has a binding entitlement, may be six to eighteen months away. For claimants concerned about the respondent’s solvency or the vessel’s continued presence in a reachable jurisdiction, that gap is the core risk that arrest addresses.

Liability and risks for claimants and shipowners

Arrest carries a specific downside: wrongful arrest. If a Nigerian court finds that the claimant arrested the vessel without a reasonable basis, for example, by inflating the claim, arresting the wrong ship, or proceeding on a claim that does not qualify under the AJA, the claimant may be liable for damages. These damages can be substantial, encompassing lost earnings, demurrage, and costs incurred by the shipowner during the period of wrongful detention. Nigerian courts have awarded wrongful arrest damages in reported cases, and P&I clubs routinely advise members on the exposure.

Arbitration’s principal risk operates at the back end: the claimant invests time and money to obtain an award, only to face enforcement difficulties. The award may be challenged on procedural grounds, or, as recent developments suggest, the Federal High Court may decline to enforce certain foreign maritime awards on specific grounds. This risk materialised in a reported February 2026 Federal High Court decision discussed below.

Enforceability: domestic judgments vs foreign arbitral awards

An arrest leading to judgment or judicial sale in the Federal High Court produces a domestic enforcement outcome, the proceeds of sale or the security provided satisfy the judgment directly under the court’s supervision. Judicial sale of vessels is an established feature of Nigerian admiralty practice under the AJA and the AJPR. The enforceability of foreign arbitral awards in Nigeria rests on the New York Convention 1958 (to which Nigeria acceded) and the Arbitration and Mediation Act 2023. In principle, foreign arbitral awards are enforceable in Nigeria.

However, the February 2026 Federal High Court development, reported in practitioner alerts and case notes, indicates that the court declined to enforce a foreign arbitral award in a maritime claim on grounds that raised questions about the scope of recognition for certain categories of foreign maritime awards. Early indications suggest this decision, if upheld on appeal, may narrow the practical enforceability of some foreign maritime awards and increase the strategic value of securing local in-rem security as a parallel measure.

Regulatory burden and court practice under AJPR 2023

The Admiralty Jurisdiction Procedure Rules 2023 modernised and clarified the procedural framework for admiralty actions in the Federal High Court. Key practical features include:

• Standardised arrest application procedure, prescribed forms, affidavit requirements, and timelines for service of the warrant.
• Express provision for arrest to aid foreign proceedings, enabling claimants in foreign arbitrations or court proceedings to apply for arrest as security in Nigeria.
• Substitution of security, the rules formalise the process for providing alternative security (bank guarantee, P&I LOU) and obtaining release of the vessel.
• Judicial sale mechanism, where security is not provided and the claim proceeds to judgment, the rules provide for court-ordered sale of the arrested vessel, with proceeds distributed to satisfy the judgment.

For practitioners, the AJPR 2023 reduced procedural uncertainty and made Nigerian arrest practice more predictable, a significant advantage for claimants and their P&I advisers.

What Changes in 2026: AJPR 2023 Consequences and the February 2026 FHC Development

Two developments have reshaped the maritime dispute strategy Nigeria landscape between 2023 and 2026.

First, the AJPR 2023 brought Nigerian arrest practice into alignment with international norms by confirming that the Federal High Court may arrest vessels to provide security for foreign arbitral proceedings. Before these rules, claimants with London or Singapore arbitration clauses faced ambiguity about whether Nigerian courts would exercise arrest jurisdiction solely to secure a foreign arbitral claim. That ambiguity is now resolved. The practical effect is that arrest and arbitration are no longer mutually exclusive, a claimant can arrest a vessel in Lagos to secure a London arbitration claim, then proceed with the arbitration on the merits.

Second, the February 2026 Federal High Court development reportedly saw the court decline to enforce a foreign maritime arbitral award on grounds that, according to practitioner case notes, introduced a more restrictive approach to recognition in certain maritime contexts. Industry observers expect this decision to be tested on appeal, and the precise scope of its impact remains the subject of active commentary among Nigerian admiralty practitioners. The likely practical effect, until appellate clarity emerges, is a heightened incentive for claimants to secure local in-rem security via arrest rather than relying exclusively on post-award enforcement of a foreign arbitral award. Claimants and their advisers should monitor this development closely and take legal advice on its application to their specific claim.

Decision Framework: Ship Arrest vs Arbitration in Nigeria, When to Choose Each

The following framework distills the analysis above into actionable decision triggers. Use the table and bullet lists below as a rapid-assessment tool before instructing counsel.

Choose ship arrest (in rem) when:

• The vessel is in or will call at a Nigerian port and may not return.
• You need immediate security and cannot wait for an arbitral award.
• You suspect enforcement of a foreign arbitral award may be uncertain in Nigeria, especially following the February 2026 FHC development.
• The commercial exposure from detention costs is lower than the risk of the respondent dissipating assets or the vessel leaving the jurisdiction.
• The claim qualifies as a maritime claim under the AJA and the evidentiary basis is strong enough to withstand a wrongful arrest challenge.

Choose arbitration when:

• The contract contains a mandatory arbitration clause and you risk a stay of court proceedings if you commence in-rem proceedings on the merits.
• The parties want specialist maritime arbitrators rather than generalist court adjudication.
• Confidentiality and finality matter more than immediate seizure of the vessel.
• Viable interim security exists, for example, a reputable P&I club has issued a LOU, or the respondent has substantial Nigerian assets.
• Enforcement in the chosen arbitral seat and in Nigeria (or another enforcement jurisdiction) is reliable and the February 2026 FHC concern does not apply to your category of claim.

Example fact patterns

• Unpaid bunkers, vessel in Lagos: Choose arrest. The bunker supplier has a clear maritime claim, the vessel is present, and the claim amount is quantifiable. Arrest secures the claim immediately. Pursue the merits through arbitration or admiralty proceedings after security is in place.
• Cargo damage, charterparty with London arbitration clause, vessel calling at Apapa: Choose both, arrest the vessel for security under AJPR 2023 (to aid the London arbitration), then pursue the arbitration on the merits. The arrest secures the claim; the arbitration resolves it.
• Freight dispute, respondent solvent with good P&I cover, no vessel currently in Nigeria: Choose arbitration. No vessel to arrest; the P&I club can provide a LOU; the arbitration clause governs. Monitor for a vessel call if security becomes an issue.

When to Engage a Maritime Lawyer for the Ship Arrest vs Arbitration Decision

This decision is time-critical and carries significant financial consequences. Engage a qualified Nigerian admiralty lawyer immediately if any of the following conditions are present:

• The vessel is in or approaching a Nigerian port and you have an outstanding maritime claim, the window for arrest may be hours, not days.
• You have received notice that the vessel will depart Nigerian waters and you do not hold security (LOU, bank guarantee, or other undertaking).
• Your contract contains an arbitration clause and you need to determine whether arrest for security is available alongside or instead of arbitral interim measures.
• The amount at stake is material, as a practical threshold, any maritime claim exceeding USD 100,000 warrants immediate legal assessment of the security and enforcement strategy.
• A P&I club is involved, on either side, and negotiations over LOUs, security terms, or club correspondence require coordinated legal strategy.

Onboarding checklist for counsel (prepare within 24 hours)

• Charterparty, bill of lading, or contract giving rise to the claim.
• Invoices, statements of account, or quantification of the claim.
• Proof of demand or notice to the respondent.
• Current vessel location and anticipated port calls (AIS data or agent reports).
• Any existing LOUs, guarantees, or P&I correspondence.
• Contact details for insurers and P&I correspondents.
