Ship arrest is one of the most powerful remedies in maritime law. A vessel earning thousands of dollars a day in hire is, by its nature, mobile — and once it sails, recovering money from a defaulting owner or charterer becomes an exercise in jurisdictional chase. The arrest remedy reverses that dynamic: detain the vessel in port and the owner is forced to the negotiating table within days, often hours.

For the Indian bar, the framework changed materially with the Admiralty (Jurisdiction and Settlement of Maritime Claims) Act, 2017. Before 2017, ship-arrest practice rested on inherited English common-law principles, the 1952 Arrest Convention, and a patchwork of High Court rules. The 2017 Act consolidates the law and gives clear admiralty jurisdiction to the High Courts of Bombay, Madras, Calcutta, Delhi, Karnataka, Andhra Pradesh, Telangana, Gujarat, and Kerala.

What is a “maritime claim”?

Section 4 of the Act lists eighteen categories of maritime claim. The most commonly invoked include unpaid freight or hire, damage to or loss of cargo, charterparty disputes, salvage services, towage and pilotage, supplies (bunkers, stores, provisions), wages and crew costs, ship mortgages, and insurance premiums. Importantly, the claim must be against the ship itself or against a person who would be personally liable on the claim — arrest is an in rem remedy.

Which High Court has jurisdiction?

The ship must be physically within the territorial waters of the High Court whose jurisdiction is invoked. For practical purposes, this means Bombay (for Mumbai/JNPT), Madras (for Chennai/Ennore/Kamarajar), Calcutta (for Kolkata/Haldia), Gujarat (for Mundra/Pipavav/Hazira), and Kerala (for Cochin/Vizhinjam). Bombay and Madras dominate the case load.

The practical sequence

The process moves fast because it must. A typical arrest unfolds across a single working day — sometimes overnight if the vessel is about to sail. Counsel files an admiralty suit with a chamber-summons application, supported by an affidavit and documentary proof of the underlying claim. The High Court, satisfied of a prima facie case and that the claim falls under the Act, issues a warrant of arrest. The warrant is then served on the Sheriff and the Master of the vessel, and on the port authority, which physically prevents the ship from sailing.

Within days, the shipowner’s P&I Club typically arranges security — either a Letter of Undertaking (LoU) acceptable to the claimant, a bank guarantee, or a cash deposit in court — and the vessel is released. The substantive dispute may then continue for years, but the security is locked in.

What the practitioner has to get right

Three things tend to determine whether an arrest holds. The first is the documentary base — the underlying claim must be provable on the face of the papers, because the application is decided ex parte and the court will not entertain conjecture. The second is the choice of forum: claimants sometimes file in the wrong High Court because the vessel was last reported there, only to find it has shifted port by the time the warrant issues. The third is speed. A vessel in an Indian port is typically there for 36–72 hours. If the application is filed on day three, the ship is already at sea.

There is also the question of wrongful arrest. If the claim turns out to be unsustainable, the arresting party can be liable in damages for the vessel’s detention — daily hire, fuel, port dues, possibly consequential losses. Indian courts have not awarded such damages liberally, but the risk is real and should temper enthusiasm for arrest as a tactical lever rather than a genuine remedy.

Where the remedy doesn’t reach

Sister-ship arrest is permitted under Section 5(2) of the Act — a claimant may arrest any other ship in the same beneficial ownership as the offending vessel. This expands the practical reach considerably. However, associated-ship arrest (where ownership is structured through different SPVs but the controlling mind is the same) remains contentious. Courts will pierce the veil in clear cases, but the evidentiary threshold is high.

For a shipowner facing arrest, the playbook is well-rehearsed: provide acceptable security quickly, get the ship released, and fight the substantive dispute on its merits. For a claimant considering arrest, the calculus is whether the security obtained will actually be collectible — arresting a ship owned by a one-vessel SPV with no other assets is, at best, a Pyrrhic victory.

If you have a maritime claim where the debtor’s ship is about to call at an Indian port — or has just arrived — the window to act is short. We respond to arrest enquiries within four hours, including weekends.

Every commercial vessel of any meaningful size carries two layers of insurance. The first is Hull and Machinery (H&M) — cover for damage to the ship itself, written by commercial insurers on the open market. The second is Protection and Indemnity (P&I) cover, written almost exclusively by the thirteen mutual clubs of the International Group, which between them cover roughly 90% of the world’s ocean-going tonnage.

P&I is, in essence, third-party liability cover for shipowners. It picks up where H&M leaves off — cargo claims, crew claims, collision liability above the H&M limit, pollution, wreck removal, FFO (fixed and floating object) damage, stowaways, and a long catalogue of other exposures that shipping operations generate. For most shipowners, the P&I premium is a meaningful operating cost; for most claimants, the existence of P&I cover is what makes recovery realistic.

Why mutual clubs, not insurance companies?

P&I cover is mutual: members are also the owners of the club. There is no upper limit on liability cover (technically, there is a “pool” arrangement among the International Group, but the headline number runs into billions of dollars). Premiums are calls, often supplementary, decided based on the year’s loss experience. The model evolved because conventional insurance markets would not write the unbounded liabilities that maritime operations generate — only a mutual pool of shipowners themselves was willing to underwrite that risk.

The “pay-to-pay” rule

One feature of P&I cover trips up claimants regularly. Traditionally, the Club indemnifies the member only after the member has actually paid the claimant. A cargo claimant who has obtained a judgment against the shipowner cannot, in principle, sue the Club directly — the shipowner must first pay, and then claim reimbursement from the Club.

In practice, this is rarely how things work. Where the shipowner is solvent and on cover, the Club typically provides a Letter of Undertaking (LoU) to the claimant before any judgment, which secures the claim and allows the ship to be released from arrest or the cargo to be discharged. The pay-to-pay rule matters most when the shipowner is insolvent, has lost cover for breach of the Club rules, or has been struck off — in which case claimants discover, often painfully, that the Club is not a deep pocket they can sue directly.

The common claim types

Cargo claims dominate the volume — short delivery, contamination, wet damage, late delivery, mis-delivery against a forged bill of lading. Most are resolved by negotiation, often with the Club’s recommended local correspondents handling the front-line discussions.

Crew claims have grown materially in importance since the Maritime Labour Convention, 2006 entered force in India in 2015. These cover wages, repatriation, illness and injury, and death. They tend to settle quickly because Clubs (and Flag States) treat MLC compliance as non-negotiable.

Collision and FFO liability typically involves apportionment of fault between the vessels involved, with each side’s Club handling its member’s share. Pollution claims — oil, chemical, plastic — are increasingly governed by international conventions (CLC, Fund, HNS, Bunkers Convention) and are handled with intense coordination between Club, Flag State, and the coastal state involved.

What the legal practitioner contributes

A P&I matter that reaches a lawyer’s desk has usually escalated beyond the Club’s local correspondent. Common scenarios: the claim has been disputed, security has been refused, the underlying contract (a charterparty or B/L) contains a jurisdiction or arbitration clause that needs litigating, or the shipowner has lost cover and the claimant is exploring direct action against the Club under the relevant flag state’s direct-action statute.

For Indian admiralty practice, the most common involvement is on ship-arrest applications where the underlying claim is a P&I-covered exposure (cargo damage, crew wages, collision). The arrest secures the claim; the Club then provides security; the substantive dispute proceeds — often in London arbitration, sometimes in Indian admiralty court — on its merits.

For charterers and cargo interests

Charterers usually carry separate charterers’ liability cover, which is a P&I-equivalent product. Cargo interests carry cargo insurance on the goods themselves, which is independent of any cover the ship carries. Understanding the layered structure of cover is essential when a casualty occurs: who pays the salvor, who pays general average, who pays for the crew’s repatriation, and whose lawyers will conduct the recovery against whom — the answers depend on the precise cover in place and the contracts that connect the parties.

For P&I-related matters — whether you are the member, the claimant, or the cover-holder dealing with an Indian-end issue — we work directly with most International Group correspondents and can move quickly through the Indian end of the work.
