Ship arrest in Turkey is one of the most powerful interim remedies available in maritime disputes. For shipowners, charterers, cargo interests, bunker suppliers, repair yards, crew members, mortgagees, marine insurers, and other maritime creditors, the ability to detain a vessel in Turkish waters can be commercially decisive. Turkey sits on major regional and international sea routes, its ports handle dense traffic year-round, and its legal system offers a structured ship arrest regime under the Turkish Commercial Code. That combination makes arrest of ships in Turkey a subject of real importance for both domestic and foreign maritime businesses.
The current framework is rooted mainly in Book Five of the Turkish Commercial Code No. 6102. Turkey also approved accession to the 1999 International Convention on Arrest of Ships by Law No. 6904 in 2017, later deposited its accession on 11 September 2019, and the Convention entered into force for Turkey on 11 December 2019. At the same time, Turkish commentators and practitioners consistently note that the Turkish Commercial Code had already been drafted largely in line with the 1999 Convention model before Turkey’s accession took effect.
For international clients, the key point is simple: a vessel located in Turkish waters may be exposed to arrest under Turkish procedure even if the substantive dispute is governed by foreign law or subject to foreign arbitration. That makes Turkish ship arrest practice strategically important well beyond Turkish-flagged vessels or Turkish-owned maritime assets.
What Is Ship Arrest Under Turkish Law?
Under Turkish law, the relevant interim remedy is ihtiyati haciz, usually translated in maritime practice as ship arrest or precautionary attachment of a ship. Article 1353 of the Turkish Commercial Code is the starting point. It states that, to secure a maritime claim, the court may order only the arrest of the ship; for such maritime claims, an injunction over the ship or any other form of detention outside the arrest regime is not the correct route. The same provision also makes clear that ships cannot be arrested for non-maritime claims under the special ship-arrest regime.
This matters because Turkish law does not treat ships like ordinary assets for all purposes. If the claim is a non-maritime claim, a creditor may still seek general interim attachment against other assets under the Enforcement and Bankruptcy Code, but the special rules for ship arrest in Turkey are reserved for claims that qualify as maritime claims under the Commercial Code. That distinction is fundamental and often determines whether an application will succeed or fail at the threshold stage.
The Legal Basis: Maritime Claims Only
A ship may be arrested in Turkey only if the underlying claim falls within the statutory list of maritime claims in Article 1352 of the Turkish Commercial Code. Turkish sources describe that list as numerus clausus, meaning closed and exhaustive. In practice, that means the applicant must do more than show that money is owed; the applicant must also show that the debt is one of the specific maritime claims recognized by Turkish law.
The statutory list is broad and commercially significant. It includes, among other things, claims arising from damage caused by the operation of the ship, personal injury or loss of life connected with the ship’s operation, salvage, environmental damage, wreck removal, charterparty disputes, contracts for the carriage of goods or passengers, cargo loss or damage, general average, towage, pilotage, supplies and bunkers, shipbuilding and repair, port and waterway dues, crew wages, disbursements, insurance premiums, agency commissions, disputes over ownership or possession, disputes between co-owners, ship mortgages, and disputes arising from ship sale contracts.
From a practical perspective, this means that many of the disputes most common in shipping business can support arrest in Turkey: unpaid bunkers, port charges, crew claims, charterparty claims, cargo disputes, shipyard invoices, mortgage enforcement, agency fees, and ownership conflicts. But the classification exercise is critical. A poorly framed petition may fail not because the debt is unreal, but because the creditor has not properly linked the debt to one of the maritime-claim categories recognized by Article 1352.
Arrest Is Claim-Specific, Not Open-Ended
Article 1353 also contains two operationally important rules. First, if the claim is maritime, the relevant interim remedy is ship arrest, not a different provisional measure aimed at stopping the ship. Second, if the claim is not maritime, the vessel cannot be arrested through the special maritime arrest regime. Turkish courts therefore expect a disciplined classification analysis at the application stage.
The same article further provides that ship arrest may also be requested for not-yet-due maritime claims when the conditions in Article 257(2) of the Enforcement and Bankruptcy Code are met. In broad terms, that concerns situations where recovery is endangered because of fraudulent conduct, preparations to abscond, or disappearance of the debtor. As a result, Turkish law does not limit ship arrest only to matured debts in every case, but the creditor then carries a heavier evidential and procedural burden.
Which Ships Can Be Arrested?
One of the most important questions in any arrest of ships in Turkey analysis is not merely whether the claim is maritime, but which ship can be arrested. Article 1369 deals with this issue and sets out specific ownership and liability conditions. In simplified terms, the “offending ship” may be arrested if, when the maritime claim arose, the relevant person was the owner or charterer, and at the time of arrest that same person is still liable and is the owner of the ship; arrest is also possible where the claim is secured by a ship mortgage or similar right in rem, where the dispute concerns ownership or possession of the ship, or where the claim gives rise to maritime-lien status under Article 1320.
Article 1369 also permits arrest of ships other than the specific ship connected with the claim in certain circumstances. This is the statutory basis generally discussed in practice as sister ship arrest. The rule is not unlimited. It requires, at the time of arrest, that the other ship belong to the person liable for the maritime claim, and that at the time the claim arose that same person had a qualifying relationship to the original ship, such as ownership or status as charterer, allotted operator, or carrier. For disputes specifically about ownership or possession, however, only the ship that is the subject of that dispute may be arrested.
This is an area where many applications fail. Maritime creditors sometimes assume that group-company structures, commercial control, or operational linkage are enough. Turkish law is more exacting. Ownership, the capacity in which the debtor stood when the claim arose, and the present ownership position at the time of arrest all matter. A creditor that misidentifies the liable party or the relevant ownership chain risks not only rejection, but also later exposure to wrongful arrest arguments.
Competent Courts for Ship Arrest in Turkey
Turkish law makes a sharp distinction between Turkish-flagged and foreign-flagged ships for jurisdictional purposes. Under Article 1354, for Turkish-flagged vessels, the arrest order may be sought from the court where the ship has anchored, moored, berthed, or been hauled up, and also, depending on registration status, from the ship registry court, the owner’s domicile court, or in certain special-registry cases the charterer’s domicile court. Under Article 1355, for foreign-flagged vessels in Turkey, the competent court is only the court of the place where the vessel has anchored, moored, berthed, or been hauled up.
That rule is commercially important. If a foreign vessel has physically called at a Turkish port or otherwise paused within the territorial reach contemplated by the statute, the local Turkish court at that place can become the gateway for arrest. Conversely, the requirement that the vessel be at the relevant place means that timing is strategic. Creditors often need to act fast, sometimes within a narrow operational window before the vessel sails.
A further point that matters in international disputes is that Turkish legislative reasoning expressly supports the availability of arrest in Turkey even where the merits are subject to a foreign court clause, arbitration clause, or foreign substantive law. In other words, Turkish courts may grant ship arrest as a security measure even if they will not ultimately decide the substantive dispute. That makes Turkey especially relevant in support of foreign-seated arbitration and cross-border maritime litigation.
Turkish Law Applies to the Arrest Procedure
The Turkish Commercial Code adopts the lex fori approach to maritime enforcement. Article 1350, as summarized by Turkish commentary and practitioner sources, provides that arrest, execution, judicial sale, and related enforcement consequences are governed by the law of the country where the vessel is located at the time of enforcement. In practical terms, if the ship is in Turkish waters, Turkish procedural law governs the arrest application and subsequent enforcement stages, regardless of flag.
This is why foreign creditors should not assume that the governing law of the charterparty, bill of lading, bunker contract, or mortgage automatically controls the arrest mechanics. The substantive claim may be English-law, Swiss-law, or subject to London arbitration, but the actual detention of the ship in Turkey is handled through Turkish arrest procedure.
Threshold Proof: Prima Facie Maritime Claim and Claim Value
Turkish practice does not require a full trial on the merits at the arrest stage, but the applicant must do more than make a bare allegation. Practitioner sources summarizing the Code explain that the applicant must present material showing, prima facie, both that the claim qualifies as a maritime claim and what the amount of the claim is. Courts assess whether the documents are persuasive enough at first appearance; in practice, this review is often conducted without a hearing unless the court decides otherwise.
This has obvious drafting implications. A well-prepared application should normally connect the claim to the correct Article 1352 category, set out the debtor-ship relationship required by Article 1369, quantify principal, interest, and costs, and attach the core supporting documents such as contracts, invoices, statements of account, notices, delivery records, registry extracts, AIS or port call data, and, when relevant, class or casualty materials. Weak documentary preparation can turn an otherwise strong commercial claim into a vulnerable arrest application.
Counter-Security: The 10,000 SDR Rule
One of the most distinctive features of ship arrest in Turkey is the statutory counter-security requirement. Article 1363 states that the creditor seeking arrest to secure a maritime claim must provide security in the amount of 10,000 Special Drawing Rights (SDR). The same article also allows the opposing party to ask the court to increase that amount, taking into account daily operating expenses and earnings lost while the vessel is detained. If the court orders additional security and the creditor does not provide it within the specified time, the arrest automatically falls away.
This is not a technical side issue. It is part of the commercial calculus of arrest in Turkey. The statutory 10,000 SDR is the entry point, but if the detention threatens serious off-hire loss, port costs, or other operating expense exposure, the ship interest may seek an increase. The creditor must therefore think not only about the strength of the maritime claim, but also about the economics of detention and the potential downside if the arrest is challenged as excessive or wrongful.
Article 1363 also contains an important exception: claimants holding maritime-lien type claims under Article 1320(1)(a), notably certain crew-related claims, are exempt from the obligation to post this security. That reflects the strong protective approach Turkish law takes toward those claims.
Enforcing the Arrest Order: The Three-Business-Day Trap
Obtaining the court order is only one step. Article 1364 requires the creditor to apply for enforcement of the arrest order through the competent enforcement office within three business days from the date of the order. If the creditor fails to do so, the order lapses automatically. Turkish practitioner commentary emphasizes this deadline as a strict operational requirement.
Once enforcement is requested, the vessel is taken under custody and the arrest is notified to the master or to the owner, operator, or their representative. Relevant Turkish authorities such as the harbor master, customs authority, and coast guard-related authorities are also informed. In real-world terms, this is the moment when the arrest moves from a paper remedy to an operational detention with immediate commercial consequences.
For maritime creditors, the lesson is obvious: do not treat the court order as the finish line. For shipowners and operators, the practical lesson is the reverse: the period immediately after the order is granted is often the narrowest window for negotiating release security, challenging service, or making urgent submissions before the detention begins to create cascading port, schedule, and charterparty consequences.
After Arrest: The Merits and the One-Month Follow-Up
If there is no jurisdiction or arbitration agreement on the merits, Article 1359 provides that the Turkish court competent to grant the arrest is also competent for the substantive action that will complete the arrest, and the enforcement office that implemented the arrest is competent for the execution proceedings. That gives the Turkish arrest court an important follow-on role where forum has not already been fixed by agreement.
At the same time, Turkish maritime practice also requires the creditor to proceed with complementary merits action or debt collection within the statutory period after arrest. Practitioner sources summarizing the relevant rules explain that, for ship arrests, the ordinary follow-up periods are extended so that the creditor must commence the necessary substantive or enforcement proceedings within one month after enforcement of the arrest, failing which the arrest loses effect.
This is a major risk point. Some claimants focus intensely on obtaining the arrest order, then lose leverage because the complementary action is not filed in time, or because the arbitration step, court action, or debt collection proceeding is started in the wrong forum. A successful arrest strategy in Turkey therefore always includes a post-arrest merits plan from day one.
Release of the Vessel
Turkish law also provides clear mechanisms for releasing an arrested vessel. Article 1371 allows the shipowner or debtor to ask the court to lift the arrest by providing sufficient security covering the full maritime claim, interest, and costs, up to the value of the ship. After debt-collection proceedings have started, the relevant authority shifts to the enforcement court.
This matters because, in practice, the commercial battle often shifts quickly from “Can the ship be arrested?” to “What security is enough for release?” Legislative materials further indicate that the nature and amount of security can be agreed between the parties, and that P&I Club letters or other negotiated security instruments may play a practical role where accepted by the creditor and the court. Providing release security is not treated as an admission of liability or a waiver of defenses.
From the owner’s perspective, the ability to substitute security for the vessel is crucial. From the creditor’s perspective, it often converts a difficult moving asset into a more stable security fund. But both sides must think carefully about wording, amount, forum linkage, and whether the proposed security truly protects costs, interest, and enforcement prospects.
Practical Risks in Ship Arrest Cases in Turkey
The biggest practical risk for creditors is wrongful arrest. Turkish law gives ship arrest real force, but that force comes with responsibility. If the debt is not truly maritime, if the debtor-ship ownership link is defective, if the wrong vessel is targeted, or if the evidentiary file is too weak, the arrest may be challenged and the creditor may face exposure for detention losses. Turkish sources expressly note that counter-security exists to cover probable wrongful attachment losses.
A second major risk is ownership analysis error. Article 1369 is technical. Group structures, commercial managers, beneficial ownership assumptions, and charter arrangements often create confusion. In Turkish arrest practice, those details are not peripheral; they are central. Getting them wrong may defeat the arrest or weaken the creditor’s bargaining position from the outset.
A third risk is timing failure. The three-business-day enforcement deadline and the one-month complementary-proceedings requirement are short and unforgiving. Even a strong maritime claim may lose immediate security value if counsel and the client are not prepared to move across court, enforcement office, and substantive forum in a coordinated way.
A fourth risk is underestimating detention economics. Article 1363 expressly allows the court to consider daily operating expenses and loss of earnings when asked to increase counter-security. That reflects commercial reality: a detained ship can generate very substantial loss in a short period. Creditors should understand that ship arrest is powerful, but it is also costly litigation pressure that can reverse against them if mishandled.
Conclusion
Ship arrest in Turkey is a sophisticated and commercially potent remedy, but it is not a blunt instrument. It works only for qualifying maritime claims. It depends on careful analysis of the statutory categories in Article 1352, the exclusivity rule in Article 1353, the jurisdiction rules for Turkish- and foreign-flagged vessels, the ship-selection rules in Article 1369, the 10,000 SDR counter-security requirement, the three-business-day enforcement deadline, and the need to follow through promptly with complementary proceedings.
For creditors, the Turkish regime offers real leverage when a vessel is in Turkish waters and the evidentiary file is strong. For shipowners and operators, it creates a serious operational risk that must be managed immediately through jurisdictional objections, ownership analysis, release security, and merits planning. In both directions, the central truth is the same: an arrest of a ship in Turkey is won or lost on legal classification, documentary precision, and speed.
