How we assist from here
From Istanbul, we handle the firm's Türkiye-related work directly, commercial and contractual disputes before the Turkish courts and in arbitration, company and shareholder matters, insurance and maritime work, real estate, and the recognition and enforcement of foreign judgments and awards. Senior lawyers stay close to each matter rather than passing it down a chain.
Istanbul is also the coordination point for international clients: inbound investment and market entry, and cross-border matters that touch Türkiye on one side and Northern Cyprus, London or another jurisdiction on the other. Clients deal with one team that holds the whole picture.

A guarantee that is valid in London can still fail where the money is.

Most newbuilding contracts with Turkish shipyards are governed by English law and refer disputes to London arbitration, and the buyer's instalments are secured by a refund guarantee from a Turkish bank. The contract is decided in London, but the hull, the yard and usually the bank are in Türkiye. A buyer's protection depends on a guarantee that can be called and collected without the help of a Turkish court, and on knowing which questions Turkish law answers whatever the contract says.

Merger Control in Türkiye: Control, Notification, Technology Transactions and Closing Risk
Turkish merger control turns on more than transaction value or shareholding percentage. A transaction must first amount to a lasting change of control, after which turnover, technology-sector rules, joint ventures, cross-border effects and closing mechanics determine whether Competition Board clearance is required. This briefing examines the 2026 regime from transaction structuring through clearance and closing.
