Since 2016, Erdem & Erdem has been ranked as one of the top 100 law firms in the world in the area of arbitration by the Global Arbitration Review. Our arbitration team represents domestic and international clients in various lawsuits carried out before national and international arbitration institutions, as well as ad hoc arbitral tribunals. Our international arbitration team handles cases under the rules of every major arbitration system, under common law and civil law systems, and in English, French, and other languages.

Our alternative dispute resolution lawyers ensure that disputes in a wide range of industries, including energy, mining, manufacturing, transportation, telecommunications, construction, finance, manufacturing, and sports, are handled through arbitration. We are lead counsel in commercial and investment-treaty disputes arising in Western Europe, Asia, Africa, Middle East and Far East involving claims valued in the billions of dollars.

Our team has extensive experience with the international institutions that administer international arbitration and dispute settlement (ICC, UNCITRAL, SRIA, TRAC, Swiss Rules of Arbitration) and are often selected as chairs, sole and party-appointed arbitrators in both commercial and investor-state arbitrations.

Our approach in international arbitration aims to provide clients strong advocacy, effective risk management and experience. We help our clients manage risks inherent in transacting and investing abroad by drafting effective dispute resolution agreements and structuring transactions to take full advantage of protections available under international trade and investment treaties, as well as planning and managing potential future disputes, particularly in project finance and energy transactions, joint ventures, technology transfers, and corporate financing. In resolving both commercial and investor-state disputes, we apply our extensive experience in collecting complex evidence, analyzing applicable law and procedures, and developing alternative strategies.
