ONGUR & PARTNERS stands prominently as one of the top-ranking, elite international arbitration law offices in Turkey, with our team’s profound trial experience and cross-border capabilities universally recognized by independent global legal networks. In a landmark high-stakes dispute, our international tribunal task force successfully represented a massive-scale multinational defense and IT corporation against a prominent Turkish technology and manufacturing enterprise in a complex, multi-million dollar ICC arbitration action.
Due to our aggressive, data-driven pre-trial strategies and unassailable legal maneuvering, the counterparty was compelled to fully accept all corporate claims of our global client, duly paying the entire claimed amount in full before the arbitral tribunal even rendered a final award. Reflecting our long-term partnership commitment, we continue to act as primary lead counsel for that multinational defense giant across several complex litigations, while providing them with comprehensive, turn-key corporate legal advice continuously since 2009.
Our extensive institutional experience in high-value ICC cases includes the premium representation of international direct investors holding strategic asset portfolios both within Turkey and across diverse overseas jurisdictions. Furthermore, our firm has been repeatedly appointed to represent leading Turkish construction conglomerates and international engineering joint ventures in major ICC dispute actions relating to the structural execution of multi-billion dollar Public-Private Partnerships (PPP) projects and complex private commercial contracts.
To deliver a complete strategic and administrative advantage across these transnational disputes, our dual-hub legal infrastructure operates with absolute precision. While our prominent istanbul law office networks drive the commercial transaction analysis, financial damage modeling, and local enforcement of arbitral awards, our central ankara law office headquarters directly manages sovereign treaty interpretation, coordinate cross-border legalizations, and handle high-level diplomacy with foreign embassies and central state departments.
Whether a cross-border dispute requires an elite corporate istanbul lawyer to secure immediate asset freezing injunctions and navigate metropolitan commercial dockets, or a seasoned ankara lawyer to oversee state immunity actions and pilot public policy defenses, our synchronized team ensures absolute asset immunity across our premier law firm in istanbul and leading ankara law firm platforms.
In addition to our primary tribunal advocacy, we regularly provide expert, high-level legal engineering and co-counseling services to elite international law firms representing global direct investors before **ICSID (International Centre for Settlement of Investment Disputes)** tribunals in high-stakes sovereign conflicts arising from foreign investments in Turkey.
In particular, our multilingual team of english speaking lawyers delivers critical, strategic advice on Turkish statutory law relating to the specific infrastructure assets at issue, alongside the precise, technical interpretation of **Bilateral Investment Treaties (BITs)** signed between the Republic of Türkiye and foreign sovereign States.
To secure your transnational contracts, insert unassailable dispute clauses, or retain premier trial advocacy for an upcoming ICC, ICSID, or ISTAC tribunal action, please contact our managing partners directly via our central International Law Firm in Turkey portal.
