Ship Arrest in Iranian Law

Ship Arrest in Iranian Law

Ship arrest is the act of preventing a vessel from continuing its operations at sea or in port and placing it under physical detention by competent authorities. Under Iranian law, ship arrest may arise in civil, commercial, or criminal contexts. It may be ordered due to outstanding debts, breach of obligations, or to adjudicate a dispute. A vessel, as a legally distinctive asset under maritime law, is subject to specific rules under Iranian Maritime Law and the regulations and procedures of the Ports and Maritime Organization.

An arrest may be ordered by a court or requested by an interested party, and its primary purpose is typically to secure a claim or to enforce a judgment. During the arrest process, the ship is not permitted to leave the port without legal authorization. The competent authority to issue an arrest order is generally the civil court with jurisdiction over the relevant port, while the port administration acts as the executing body. Because a ship arrest can cause substantial commercial and financial losses to the owner or operator, issuing such an order requires careful judicial scrutiny and compliance with strict legal requirements.

Legal Requirements for Arresting a Ship

Several essential conditions must be met for a lawful ship arrest. First, there must be a legitimate claim or demand asserted by a creditor or claimant. This claim may arise from a contract of carriage, collision damage, the financial obligations of the owner or charterer, or other legally recognized rights. Second, a competent judicial authority must issue the arrest order, typically the public civil court with jurisdiction over the port. Third, the applicant must present sufficient evidence and reasonable grounds supporting the claim.

Where the court finds a risk of loss or dissipation of rights, it may issue an arrest order. In some cases, the applicant must deposit security to cover potential damages, so that if the claim is later rejected, compensation for the shipowner’s losses can be made. Emergency arrest may also be available through interim measures, provided that the main claim is filed promptly thereafter. Any arrest imposed without a judicial order or in violation of legal requirements is unlawful and void, and the applicant may be held liable for damages. Observing these requirements helps prevent abuse and protects the shipowner from unjustified interference.

The Competent Authority for Ship Arrest

In Iran, the public civil court with jurisdiction over the port where the vessel is berthed or is expected to berth is generally competent to hear and decide a ship arrest request. In certain circumstances, specialized branches dealing with international commercial matters may also become involved, particularly where disputes relate to international carriage, marine insurance, or co-ownership of vessels.

The Ports and Maritime Organization does not independently have the authority to issue a judicial arrest order, but it is responsible for executing court decisions. Where an arrest is connected to violations of safety or maritime regulations, such as pollution incidents or breaches of security protocols, the Ports and Maritime Organization may impose a temporary administrative detention. Such measures should be reported to the judiciary without delay. In financial disputes, the interested party must submit a formal petition and supporting evidence to the court, and the judge may issue the arrest order upon confirming that legal conditions are met. Any action outside this framework lacks legal basis and may be subject to legal challenge.

The Role of the Ports and Maritime Organization in Executing a Ship Arrest

The Ports and Maritime Organization of the Islamic Republic of Iran, as the executive authority supervising port and maritime operations, plays a key role in the enforcement stage of ship arrest. It issues permits for entry, berthing, loading, and unloading, and once a judicial arrest order is served, it must promptly execute it.

Port administration will formally notify the master of the vessel or the owner’s legal representative, prevent the vessel from departing, and prohibit its exit from the port until the arrest is lifted. In practice, loading and unloading activities may also be restricted depending on the scope of the order. Where the vessel has violated technical, safety, environmental, or customs rules, the Organization may apply an administrative detention, in which case the matter should be referred to the judiciary promptly. Improper execution or undue delay may expose port officials to administrative or legal accountability. Accordingly, the Organization acts as an impartial enforcement authority and is responsible for supervising the detained vessel until the legal status is resolved.

Types of Ship Arrest in Maritime Practice

Within the Iranian legal framework, ship arrest is commonly classified into precautionary arrest and enforcement arrest. Precautionary arrest applies when a creditor seeks to secure its claim before a final judgment is issued. It is protective in nature and aims to prevent the vessel from leaving the jurisdiction or being transferred in a manner that frustrates recovery.

Enforcement arrest, by contrast, occurs after a final judgment has been issued and is used to ensure execution of the judgment, such as where the shipowner fails to pay an adjudicated debt. A further category is administrative temporary detention imposed by port authorities for technical or safety violations. In those situations, the vessel may remain in port until deficiencies are rectified or legal formalities are completed. The key differences among these forms relate to the issuing authority, the legal purpose, and the legal effects, including the practical implications for operation, sale, and the parties’ exposure to liability.

Legal Consequences of Ship Arrest for the Owner

Ship arrest can have significant legal and commercial consequences for the owner or the principal charterer. The immediate consequence is the loss of the ability to operate the vessel commercially, meaning the owner cannot deploy, charter, or move the vessel. Substantial direct financial losses may also arise from port detention, including contract terminations, delivery delays, and liability for damages owed to customers.

If arrest continues for an extended period, the owner may lose future business opportunities, face cancellation of international contracts, and suffer reputational harm with banks and insurers. From a legal standpoint, the owner may challenge the arrest and, if it is found to be unjustified, seek compensation where an arrest results from crew misconduct or non-compliance with technical standards, liability may also attach to the owner. For these reasons, vessel owners should maintain both legal and technical compliance to reduce exposure to arrest risks.

Compensation for Unlawful or Unjustified Ship Arrest

If a ship is arrested without compliance with legal requirements or based on defective evidence, the owner or operator may bring a claim for damages against the party that requested the arrest. Under general civil liability principles, any person who causes loss to another through an unjustified act and cannot prove a lawful basis may be required to compensate the injured party.

In precautionary arrests, courts commonly require the applicant to provide security for potential losses. If damages are proven and the arrest is found unjustified, this security may be used to compensate the shipowner. Recoverable losses may include lost revenue, port detention costs, contract cancellations, depreciation in the vessel’s value, and reputational damage. To succeed, the owner should present evidence such as terminated contracts, port invoices, protest correspondence, and technical reports, and may request an expert assessment to quantify losses. The public civil courts generally hear these claims. Full compensation functions as an important safeguard against improper arrests and encourages responsible use of arrest remedies.

The Difference Between Arresting Iranian and Foreign Ships

The arrest of a foreign ship in Iran is subject to additional considerations under private international law. The general principle is respect for the vessel’s flag state and sovereignty. However, when a foreign ship enters Iranian territorial waters or commercial ports, Iranian courts may order arrest under defined legal conditions.

Practical differences may include service on a lawful representative, diplomatic notifications, and the need to consider international instruments, including the 1952 Brussels Convention on the Arrest of Sea Going Ships, where relevant to the legal analysis. While the arrest of an Iranian ship typically follows domestic civil procedure, the arrest of a foreign ship may require additional safeguards, such as diplomatic channels and certified translations of documents. Because the arrest of foreign ships may create international sensitivities, judicial authorities often apply heightened caution and careful review. Applicants are also commonly expected to provide reliable security. Failure to follow proper formalities may lead to diplomatic objections and legal consequences.

Permissible Duration of Ship Arrest

The duration of the ship arrest depends on the type of arrest and the stage of proceedings. In precautionary arrest, the vessel remains detained only until a final decision is issued or until the need for security is removed. If the applicant does not file the main claim within the required timeframe, or if the court finds the arrest unjustified, the arrest should be lifted without delay.

In an enforcement arrest, detention continues until the judgment is fully executed, whether through payment of the debt or other enforcement measures, including the sale of detained assets where applicable. In certain cases, the court may allow the vessel to depart before proceedings conclude if adequate collateral or a bank guarantee is provided. The Ports and Maritime Organization is also expected to monitor the detention status. If detention continues beyond a reasonable period and causes disproportionate harm, the owner may request urgent relief or pursue damages, depending on the circumstances. Any extension without legal authority may result in liability for executing officials.

Legal Methods to Lift a Ship Arrest

Several legal routes may be used to lift a ship arrest. First, payment of the debt or compliance with the court judgment by the owner or its authorized representative may lead to an order lifting the arrest. Second, the court may accept a reliable guarantee, such as a bank guarantee or suitable collateral, as a substitute for continued detention.

Where an arrest is precautionary and issued before the main dispute is resolved, it may be lifted if the claim is rejected or the parties reach a settlement. If procedural violations occurred in issuing the arrest order, the owner may request annulment of the order and immediate release. In practice, the owner should submit a reasoned legal brief supported by documents to persuade the court to lift the arrest. Once a formal order is served, port authorities must issue exit clearance and release the vessel. Attempting to evade arrest or to leave port unlawfully may expose responsible parties to criminal liability.
