International Commercial Litigation & Dispute Resolution

Topluyıldız Legal Co.’s International Commercial Litigation & Dispute Resolution practice represents clients in high-value, multi-jurisdictional disputes that demand a combination of strategic vision, procedural mastery, and deep substantive expertise. We handle complex commercial litigation before Turkish courts — including the specialised commercial courts and regional courts of appeal — covering contractual disputes, shareholder conflicts, corporate liability claims, agency and distribution agreement terminations, and construction and engineering disputes. Our litigation approach is characterised by rigorous case assessment, early identification of dispositive issues, and the development of evidence strategies that position our clients for success at trial and on appeal.

International Arbitration

Our arbitration practice encompasses proceedings under the leading institutional rules, including the ICC (International Chamber of Commerce), ISTAC (Istanbul Arbitration Centre), and LCIA (London Court of International Arbitration). We act as counsel in both commercial arbitrations and investment treaty claims, advising claimants and respondents across sectors including energy, infrastructure, telecommunications, and financial services. Our team has experience with:

• Commercial arbitration — contract disputes, joint venture disagreements, post-M&A claims, and construction arbitrations
• Investment treaty arbitration — claims under bilateral investment treaties (BITs) and the Energy Charter Treaty, including ICSID and UNCITRAL proceedings
• Emergency and interim measures — applications for emergency arbitrator relief and court-ordered interim measures in support of arbitration
• Arbitration-related court proceedings — set-aside applications, challenges to arbitrators, and anti-suit injunctions before Turkish courts

Mediation & Enforcement of Foreign Judgments and Arbitral Awards

We advise clients on mandatory and voluntary mediation processes under Turkish law, including the mandatory mediation requirement for commercial disputes and labour claims. Where mediation is strategically advantageous, we prepare our clients to negotiate from a position of strength while preserving their litigation and arbitration options.

A critical component of our practice is the recognition and enforcement of foreign court judgments and arbitral awards in Türkiye under the International Private and Procedural Law (MOHUK) and the New York Convention. We also assist Turkish clients in enforcing Turkish judgments and awards abroad, coordinating with local counsel in the relevant enforcement jurisdiction. Our cross-border enforcement experience ensures that favourable outcomes are translated into tangible recoveries, wherever the counterparty’s assets may be located.
