Charter Party Disputes in Turkey: 2026 Owners & Charterers Guide

When a vessel sits idle off the anchorage at Ambarlı, when hire stops mid-voyage on a transit through the Bosphorus, or when a charterer refuses to pay demurrage after a delayed discharge at Aliağa, the parties almost always reach for the same document: the charter party. Charter party disputes in Turkey sit at the intersection of the Turkish Commercial Code (TCC), the parties' BIMCO/Gencon/NYPE form of choice, English law clauses tucked into a Turkish forum, and a body of Court of Cassation case law that foreign owners and charterers often discover only after the writ is served.

This 2026 guide explains, in practical terms, how Turkish courts and arbitral tribunals approach charter party disputes — whether your contract is a time charter, voyage charter, or bareboat — and what foreign owners, charterers, P&I clubs and cargo interests should expect when their dispute lands in Istanbul. Written by maritime lawyers practising before the Istanbul Commercial Courts and ISTAC, the guide is intended for readers who already understand charter party mechanics in English law and need to know what changes when Turkish jurisdiction or Turkish-flagged tonnage is involved.

Key Takeaways: What You Need to Know

• Charter parties are governed primarily by Book V of the Turkish Commercial Code (TCC), Articles 1131 to 1267, together with the parties' chosen contract form (Gencon, NYPE, Shelltime, BIMCO Bareboat).

• Foreign law and foreign arbitration clauses are generally enforceable, but cargo claims under bills of lading and certain mandatory rules can still pull a dispute into Turkish courts.

• The dedicated forums for maritime disputes in Istanbul are the Istanbul Anadolu and Istanbul (Çağlayan) Commercial Courts of First Instance, with arbitral users increasingly choosing ISTAC.

• Demurrage, off-hire and hire payment disputes are by far the most common claims; sister-ship arrest and counter-security remain the principal pre-judgment tools.

• Yargıtay 11. Hukuk Dairesi (11th Civil Chamber of the Court of Cassation) is the appellate authority for maritime commercial matters and its case law materially shapes outcomes on laytime, demurrage and redelivery condition.

The Legal Framework: TCC Book V and Beyond

The Turkish Commercial Code No. 6102 dedicates its Fifth Book entirely to maritime trade. Articles 1131-1267 cover the contract of carriage of goods by sea, charter parties (çarter sözleşmesi), bills of lading, demurrage, the law of general average and carrier liability. The drafters consciously aligned much of Book V with the Hague-Visby Rules and modern continental maritime statutes, which makes the Turkish regime broadly familiar to foreign maritime lawyers, even where the wording differs.

Three other instruments routinely interact with TCC Book V in any Turkish charter party dispute: the Turkish International Ship Registry Law No. 4490 (the TUGS regime, governing tax-privileged Turkish-flagged tonnage), the Code of Civil Procedure No. 6100 (HMK, governing court proceedings, evidence and provisional measures) and the International Arbitration Law No. 4686, which governs arbitral proceedings seated in Turkey when the dispute has a foreign element.

Turkey is a party to the principal IMO instruments that ride alongside charter contracts — SOLAS, MARPOL, COLREG, the 1989 Salvage Convention, the 1976/1996 LLMC, and the 1952 International Convention for the Arrest of Sea-Going Ships. Turkey has also ratified the 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (since 1991), which is decisive whenever a London or Paris award arrives in Istanbul for enforcement against a Turkish-flagged vessel or a Turkish charterer.

The Three Charter Forms and How Turkish Courts Read Them

Voyage Charter

In a voyage charter (sefer çarteri), the owner agrees to carry a defined cargo between named ports for a freight rate calculated per metric ton or as a lump sum. The TCC treats freight as earned on delivery unless the contract says otherwise, and the lien on cargo for freight, demurrage and general average contributions is expressly recognised under TCC Article 1201. Voyage charter disputes in Turkey overwhelmingly cluster around three themes: laytime calculation, demurrage rate and quantum, and deviation claims.

Time Charter

Under a time charter (zaman çarteri), the charterer pays hire to use the vessel for a defined period. Turkish courts read NYPE, Shelltime and BIMCO time charter forms as commercial contracts and will respect English law and London arbitration clauses if drafted clearly. The most litigated issues are off-hire claims, speed and consumption warranties, and the condition of the vessel on redelivery, particularly when the ship's hold cleanliness or bunkers fall outside the contract.

Bareboat Charter

A bareboat charter (çıplak gemi kirası) transfers possession and operational control of the vessel to the charterer, who becomes the "disponent owner" and crews and operates the ship at its own expense. In Turkey, bareboat charterers can — and frequently do — register the vessel in the TUGS bareboat registry under Law No. 4490, which is a powerful tool for foreign owners seeking to fly the Turkish flag temporarily and access Turkish cabotage routes under the Cabotage Law No. 815.

The Five Disputes That Account for Most Charter Litigation in Turkey

1. Demurrage and Laytime

Demurrage claims dominate the docket. Turkish courts apply the laytime clause as drafted and accept the international principles of "once on demurrage, always on demurrage" and the "WIBON" (whether in berth or not) regime where the contract so provides. However, evidence of port congestion, weather working day calculation and statements of facts (SOF) signed (or not signed) by the master and the agent are often decisive. The Court of Cassation has repeatedly emphasised that the master's reservation on the SOF, recorded in real time, carries significant weight.

2. Off-Hire Disputes in Time Charters

Clause 15 of the NYPE form (or its Shelltime equivalent) is the single most disputed clause in Turkish time charter litigation. The recurring fact pattern: the charterer treats the vessel as off-hire during a breakdown or hold-cleaning failure, and the owner insists hire continues. Turkish courts will look at whether the off-hire event falls within the contract's enumerated grounds, whether the loss of time is "full" or partial, and whether the time charterer has properly placed the vessel off-hire in writing.

3. Hire Payment and Withdrawal

Late or short payment of hire remains a flashpoint, especially when the owner contemplates withdrawal. Turkish courts generally enforce withdrawal clauses but expect the owner to follow the contractual notice mechanism strictly, including any anti-technicality clause. Acting prematurely on a withdrawal can convert the owner into the defaulting party and expose it to a substantial damages claim — particularly where the market has moved.

4. Cargo Claims Under Charter Parties and Bills of Lading

When cargo is damaged or short-delivered, the carrier's liability typically lies under the bill of lading rather than the charter party, even where a charter party governs the underlying commercial relationship. The TCC's carriage regime closely tracks the Hague-Visby Rules, and Turkish courts will frequently engage in a parallel analysis of the bill of lading (which may incorporate the charter party by reference) and the charter party itself.

5. Redelivery Condition and Bunkers on Redelivery

Disputes about hold cleanliness, ROB bunker quantities and the vessel's condition on redelivery are routinely arbitrated. Turkish tribunals follow the charter party's plain terms but will not allow either party to weaponise minor non-conformities to escape commercial obligations; good faith (dürüstlük kuralı) under TCC Article 18 and Article 2 of the Turkish Civil Code remains an interpretive backdrop.
