Frankfurt has emerged as one of Europe's foremost financial and commercial centres and, increasingly, as a bridge between European and Asian markets. With that growth comes an increasing demand for sophisticated dispute resolution. Signature Litigation established its Frankfurt office to meet this need, bringing our conflict-free, disputes-only platform to the German market.
FIND OUT MOREWe are delighted to announce that Signature Litigation has been recognised as one of the top arbitration firms globally in the GAR 100 2025 Guide. GAR 100 is widely recognised by the legal profession as a connoisseur of international arbitration and the go-to guide to identify those shaping the landscape. GAR provides its own news coverage of the most important cases and developments in the international arbitration sphere. When considering law firms’ submissions for GAR rankings, GAR not only reviews data provided by each firm on the disputes and hearings conducted by them, but it also relies on its in-depth knowledge of the arbitration market and conducts extensive research in order to identify the firms with 'true experience and ringcraft'.
The last several years have bolstered Signature’s already-strong arbitration practice, which is led by Signature’s long-standing arbitration Partner Ioannis Alexopolous, through our consistent commitment to attracting top arbitration talent to our team. These include the promotion of Neil Newing to our Partnership in 2022, lateral hires of Partners Tsegaye Laurendeau in September 2022 and Philipp Kurek in September 2023.
Partners Flore Poloni (who joined in September 2020) and Philip Dunham (who joined in January 2024) lead our arbitration practice in Paris, and Ulrich Helm and Dr Jan Kraayvanger lead our practice in Frankfurt since July 2024.
Signature's long-standing arbitration Partner based in London, Natalia Chumak, spearheads the strategic development focus of our arbitration practice across all our offices which allows the team to operate in a focused, collaborative and coordinated way.
As a result of this consistent commitment to growth and focused development, Signature's international arbitration practice currently represents formidable force on the market.
Equally versed in both commercial arbitration and investor-state arbitration, Signature's international arbitration team offer expertise across the energy (traditional and renewables), commodities, technology, pharmaceuticals, mining, manufacturing, transport and logistics, construction, infrastructure, telecoms, financial services, and shipping sectors. Signature has extensive expertise in corporate disputes including post-M&A, joint venture, partnership and investment disputes. Signatures geographical reach covers Africa, Middle East, countries from the former Soviet Bloc, Brazil and countries in South Asia.
Client testimonials note Signature’s “very practical advice that got straight to the point” and “strategic vision, quick reactions and perfect organisational skills”, along with an ability to break down complex issues and explain them in plain and clear language.
Signature's recognition in the GAR 100 is a significant achievement that is a timely recognition of our continued dedication to outstanding service and client satisfaction.
Partner Ioannis Alexopoulos commented, “I am thrilled that our team has achieved this important recognition. Everyone in our wonderful team has worked so hard for this and I send my congratulations to all.”
Partner Natalia Chumak commented, “This is a big and very meaningful moment for our international arbitration team. It’s a testament to our collective spirit and drive to achieve the best outcomes for our clients.”
