When a fleet is built from a chain of single-ship companies, does "ownership" for the purpose of arrest mean what the register says, or what the underlying commercial reality shows? The MSC Elsa 3 litigation gives Indian admiralty law its clearest test yet.

Introduction

Sister-ship arrest exists to solve a narrow but persistent problem in admiralty practice: what happens when the ship that caused the harm is no longer available to answer for it. The remedy, codified in India under Section 5 of the Admiralty (Jurisdiction and Settlement of Maritime Claims) Act, 2017, allows a claimant to arrest a different vessel owned by the same person, in place of the offending ship. On its face this is a modest procedural fix. In practice, it raises one of the more contested questions in modern shipping law: when a fleet is deliberately structured through a chain of single-ship companies, each nominally distinct, does "ownership" for the purpose of arrest mean what the register says, or what the underlying commercial reality shows?

This question is not academic. Shipping groups routinely register each vessel in the name of a separate special-purpose company, a practice with genuine commercial justification in ship finance and risk allocation. The same structure, however, can also be used, or alleged to be used, to insulate a controlling group from the consequences of a single vessel's conduct. Courts across jurisdictions have taken markedly different positions on how far they are willing to look behind that structure. This article examines where Indian law currently stands on that question, using the recent proceedings arising from the sinking of the MSC Elsa 3 off the Kerala coast as an illustration of how the issue plays out in practice, before turning to the harder question of where Indian law should go from here.

The Statutory Anatomy of Sister-Ship Arrest

Section 5(1) of the Admiralty Act, 2017 permits the High Court to arrest a vessel for the purpose of providing security against a maritime claim where, among other conditions, the person who owned the offending vessel when the claim arose is liable for that claim and is the owner of the vessel to be arrested at the time of arrest, or was its demise charterer at both points in time. The provision is modelled on Article 3 of the International Convention Relating to the Arrest of Sea-Going Ships, 1952 (the "Arrest Convention, 1952"), and shares its underlying premise: a claimant may only arrest a vessel other than the offending ship where the person liable in personam owned (or was demise charterer of) the offending vessel when the claim arose, and is also the owner (or demise charterer) of the vessel actually arrested at the time of arrest. The link the statute requires runs through that specific person at those two points in time; it does not extend to any vessel that happens to be commercially associated with the wrongdoer more generally.

The difficulty is that the statute does not define "owner," and in an industry where registered title is frequently held by a single-ship company created for that vessel alone, the answer to "who owns the ship" can differ sharply depending on whether one consults the register or the underlying corporate accounts. This is the fault line along which the comparative law on sister-ship arrest divides.

Three Traditions: Registered Title, Beneficial Ownership, and Associated Ships

English law has historically taken the strictest view. In The Evpo Agnic [1988] 1 WLR 1090 (CA), the Court of Appeal held that "owner" for the purpose of the equivalent English provision meant the registered owner, and refused to arrest a vessel merely because its registered owner shared the same ultimate shareholder and directors as the company that owned the ship giving rise to the claim. Lord Donaldson MR reasoned that the Arrest Convention, 1952 treated ownership and registration as one and the same, and that departing from the register would sacrifice the certainty that registration exists to provide. The decision has been read, both by English commentators and by later Commonwealth courts, as a deliberate policy choice: predictability for shipowners and financiers is worth more than the occasional claimant left without an effective remedy.

South African law sits at the opposite end of the spectrum. Under the Admiralty Jurisdiction Regulation Act, a claimant may arrest an "associated ship," defined by reference to common control of the relevant companies rather than common registered ownership, and control may in turn be inferred from a range of factors such as common management, shared officers, or common financing arrangements. This standard was adopted precisely because flag registries are easily used to defeat enforcement, and it allows South African courts to treat a fleet of nominally separate single-ship companies as a single economic unit for arrest purposes, without first proving fraud in the traditional company-law sense.

Indian law occupies a middle position, though one that has received comparatively little sustained judicial attention until recently. The Admiralty Act, 2017 does not contain an "associated ship" provision of the South African kind; it continues to speak of ownership and demise charter status. Yet Indian courts have not adopted the English insistence on registered title either. In Rainbow Ace Shipping SA Panama v MV Rainbow Ace (Notice of Motion No. 235 of 2013 in Admiralty Suit No. 29 of 2013), the Bombay High Court accepted that beneficial ownership, rather than registered title alone, could found a sister-ship arrest, drawing on Section 71 of the Merchant Shipping Act, 1958 and on the wider language of Article 3.2 of the Arrest Convention, 1999, which India has not ratified but has treated as informing the common law in this area. The Court was careful, however, to require more than shared directors or a shared address: it held that common shareholding, or an equivalent structural link, was necessary before beneficial ownership could be established, and the arrest in that case was ultimately set aside for want of such proof.

This willingness to look past the statutory text and draw on international practice is not confined to sister-ship arrest itself. In M.V. Elisabeth v Harwan Investment & Trading Pvt. Ltd. (1993 Supp (2) SCC 433), the Supreme Court held that Indian admiralty jurisdiction was not frozen at the level of a nineteenth-century colonial statute, and that Indian High Courts, as courts of record with inherent jurisdiction, were entitled to draw on the wider body of maritime principles recognised internationally, including conventions India has not ratified, in developing the law. M.V. Elisabeth did not concern sister-ship arrest at all, but it supplies the doctrinal foundation on which Rainbow Ace, and later the Akiteta II proceedings, implicitly rely: without it, an Indian court's willingness to look past a domestic statute's silence on beneficial ownership would be harder to explain.

The MSC Elsa 3 Litigation as Illustration

The proceedings arising from the sinking of the MSC Elsa 3 show how this Indian middle position operates under pressure. The State of Kerala, seeking ₹9,531 crore in compensation after the vessel sank off the Kerala coast on 25 May 2025, sought to arrest a different vessel, MSC Akiteta II, as security once MSC Elsa 3 itself became unavailable. The two vessels were registered in the names of different companies, Elsa 3 Maritime Inc. and Nairne Oceanway Ltd. respectively, which on a strict register-based reading would have taken the case outside Section 5 altogether.

The State's response, accepted by the Kerala High Court on a prima facie basis in its order dated 7 July 2025, was to plead that both companies, along with at least nine others named in the suit, were linked through a common ship manager and commercial manager, shared a common corporate address with Mediterranean Shipping Co. S.A., and were, on the documentation produced (including Equasis ship-folder records), in substance managed and controlled by it. The Court found this sufficient to justify interim arrest, while expressly reserving the final question, whether the vessels were in fact sister ships, for trial. That finding was tested again on 25 September 2025, when the Court reduced the security demanded without disturbing its earlier prima facie view.

What is notable about this sequence is that it does not represent a doctrinal departure from Rainbow Ace; if anything, it applies the same beneficial-ownership test to a considerably larger and more complex set of facts. The significance of the Akiteta II proceedings lies less in any new legal principle than in the scale at which an existing principle is being tested: a claim running into thousands of crores, a chain of ten or more single-ship companies sharing a common manager and address, and a state government, rather than a private commercial claimant, pressing the argument with the resources to litigate it fully.

Analysis: Should Indian Law Move Closer to the South African Position?

The comparative picture suggests three possible paths for Indian law, and the choice between them is not merely doctrinal but carries real consequences for how shipping is financed and insured in India.

The first is to hold the line at the Rainbow Ace standard: beneficial ownership may be pleaded and proved, but only on evidence of common shareholding or an equivalent structural link, not merely a shared address or shared management personnel. This preserves the distinction between legitimate single-ship financing structures, which are common and commercially necessary, and structures deployed specifically to frustrate enforcement. Its weakness is evidentiary: shareholding in flag-of-convenience jurisdictions is often opaque, and a claimant may struggle to obtain the documentary proof that Rainbow Ace appears to require, even in cases where the underlying control is genuinely unified.

The second path is to move toward something closer to the South African associated-ship model, treating common operational and financial control, evidenced by shared addresses, shared managers, and a demonstrated pattern of incorporating single-ship companies, as sufficient in itself, without requiring proof of common shareholding. This would make sister-ship arrest considerably more accessible to claimants facing sophisticated corporate structuring, but at a real cost to certainty. Lenders financing individual vessels through ring-fenced single-ship companies rely on the assurance that their security will not be exposed to claims against other vessels in the same fleet; a control-based test erodes that assurance for every legitimate one-ship company, not merely the ones structured in bad faith.

The third path, and the one the Kerala High Court's approach in the Akiteta II proceedings appears implicitly to be charting, is to retain the ownership-based statutory language of Section 5 while treating a documented pattern, multiple vessels, a common address, an established manager, common personnel, as strong prima facie evidence from which beneficial common ownership may be inferred at the interim stage, leaving the shipowner to rebut that inference at trial with evidence of genuine independent shareholding. This has the advantage of working within the existing statutory text, rather than requiring legislative amendment, and it places the burden of disproving a fraudulent common-ownership structure where it arguably belongs: on the party best placed to produce the true ownership records.

The practical stakes of this debate extend well beyond doctrine. For shipowners and their lenders, the Akiteta II proceedings are a reminder that a single-ship corporate structure, however carefully documented, may not by itself defeat an application for interim arrest of another vessel in the same group once a claimant assembles credible evidence of common management or control. For claimants, and particularly for public authorities pursuing large environmental or cargo claims, the case demonstrates that a persistent, well-documented effort, drawing on registry records, ship-management agreements, and corporate filings, can succeed in establishing a prima facie case for arrest even where the vessel that caused the loss is no longer available.

The trial in the Akiteta II proceedings, whenever it concludes, will be the first real opportunity for an Indian court to state which of these approaches it is in fact applying, and to do so on a factual record built up in unusual detail. Until then, the interim orders already demonstrate that Indian admiralty courts are prepared to draw adverse inferences from a documented pattern of single-ship incorporation sharing a common manager and address, without waiting for direct proof of common shareholding. Whether that is a permanent evidentiary shortcut, or merely a feature of interim relief that will not survive scrutiny at trial, is the question the eventual judgment will need to answer.

Conclusion

The debate over sister-ship arrest is, at bottom, a debate about where to place the risk of corporate structuring in shipping: on claimants, who must prove common ownership before they can secure a remedy, or on shipowners, who must justify their corporate structures once a credible pattern of common control is shown. English law places that risk squarely on claimants. South African law places it on shipowners. Indian law, as it currently stands after Rainbow Ace and now the Akiteta II proceedings, occupies an unstable middle position that has not yet been fully tested at trial. Whatever the eventual outcome at trial, the Akiteta II proceedings have already shifted the terms of the debate: the live question is no longer whether Indian admiralty courts may look beyond the register, but how far they are prepared to do so without undermining the commercial certainty on which modern shipping finance depends. How that question is answered is likely to shape Indian sister-ship jurisprudence for years to come.
