Our core mission is to inform, insulate, and protect our clients from technical legal and financial risks during their corporate business or complex legal procedures in Turkey. We achieve this by identifying the most aggressive and efficient legal strategy to succeed in complex arbitration and court litigation procedures in the shortest time possible.

1. Commercial & Corporate Litigation in Turkey

Our Turkish litigation lawyers represent multinational clients across all categories of high-value civil cases. Operating through our premier law firm in istanbul and leading ankara law firm platforms, our trial practitioners deliver fierce courtroom advocacy in complex commercial disputes, international investment conflicts, real estate property title actions, shareholder deadlocks, cross-border bankruptcy, and multi-million dollar execution proceedings, as well as complex collective labor law cases. We combine an elite international legal practice with a solid, verified track record and deep knowledge of high-stakes litigation before civil, commercial, and administrative courts.

2. Arbitration-Related Litigation & Enforcement Actions

Not all disputes arising from a cross-border contract containing an arbitration clause can be automatically resolved by way of arbitration due to strict mandatory provisions and public policy rules within Turkish statutory law. In addition, “pathological arbitration” clauses frequently drafted into international agreements can lead to severe jurisdictional complications and admissibility issues.


Our dedicated team possesses vast, practical experience in handling post-arbitral litigations, executing swift interim injunctions, and securing the recognition and enforcement of foreign arbitral awards under the New York Convention before Turkish courts, ensuring your global international awards are fully realized.

3. International Arbitration at the Highest Standard

International arbitration is at the absolute core of our worldwide legal practice. Our elite team of multilingual english speaking lawyers has been successfully representing international conglomerates and local enterprises before major institutional frameworks, including the International Chamber of Commerce (ICC), the Milan Chamber of Arbitration (CAM), the London Court of International Arbitration (LCIA), and the Istanbul Arbitration Centre (ISTAC). Whether your global enterprise requires an elite corporate istanbul lawyer to pilot fast-track commercial tribunal hearings, or a senior capital-level ankara lawyer to orchestrate high-stakes defense actions, our integrated infrastructure ensures absolute protection.

4. Administrative & Public Law Litigation in Turkey

In the Turkish legal ecosystem, sovereign administrative decisions, public sanctions, and regulatory actions are subject to strict judicial review before specialized Administrative Courts and the Council of State (Danıştay). Our capital-level ankara law office has an outstanding history of representing international clients across heavily regulated sectors—such as pharmaceuticals, national defense, public procurement, oil and gas, infrastructure, renewable energy, IT, and automotive—as well as sovereign foreign embassies and global institutions before high administrative courts against regulatory overreach, administrative pecuniary penalties, and public compliance challenges.
