Arbitration and Alternative Dispute Resolution

The international arbitration practice lies at the heart of Peters Ortner Partners. We offer one of the premier international arbitration practices in Vienna.


The firm’s partners have been involved in hundreds of arbitrations, including highly complex cases with amounts in dispute ranging in the hundreds of millions of Euros. Their international arbitration practice spans the entire globe.


  • Our international arbitration lawyers have been involved in arbitrations seated, among others, in Vienna, Frankfurt, Berlin, Munich, Amsterdam, Stockholm, London, Brussels, Paris, Geneva, Zurich, Basel, Rome, Nicosia, New York, Boston, Tokyo, Singapore, and in the capitals of almost all Eastern and South-Eastern European countries.

  • They have also been handling disputes under a truly global variety of arbitration rules, including ICSID, UNCITRAL, AAA, ICC, SCC, LCIA, LAC, SRIA, VIAC, DIS, MCC, LAR and NAI.

  • Our team members have been representing clients in disputes arising in a wide range of industries and sectors, including engineering and construction, oil and gas, telecommunications, insurance and reinsurance, luxury goods, pharma, aviation, and sports.

  • They are consistently recognized as leading arbitration practitioners in the most prestigious global rankings, including Who’s Who Legal, Chambers Global & Europe, Legal 500, Leaders League, Benchmark Litigation, and JUVE.


Our international arbitration practitioners are intimately familiar with the ins and outs of the arbitral landscape and process – as well as the art of advocacy. We pride ourselves in consistently achieving our client’s objectives through innovative and pragmatic solutions firmly rooted in rigorous factual and legal research and analysis and delivered by outstanding trial advocacy and presentation.


In appropriate cases, our lawyers also serve as arbitrators and expert witnesses on issues of international dispute resolution, and guide our clients through international commercial mediation proceedings, adjudications, and dispute board proceedings.


Peters Ortner Partners does not take a one-size-fits-all approach. We are experienced and skilled in using the flexibility of the arbitral process to the advantage or our clients – tailoring the specific tools of arbitration to the inevitable idiosyncrasies of each individual case as well as to each individual client’s needs. This includes taking seriously the size and complexity of each dispute, including in assembling the most powerful team and finding the most reasonable fee arrangement.
