Hanefeld was founded in Hamburg in 2011 by Inka Hanefeld and Jan Heiner Nedden. Hanefeld previously practised in the Vienna, New York and Hamburg offices of Freshfields Bruckhaus Deringer, and is a vice president of the ICC International Court of Arbitration. Nedden served as counsel at the ICC Court for seven years.

The boutique has two other partners who were promoted internally: Nils Schmidt-Ahrendts in 2014 and Friedrich Rosenfeld in the past year.

Hanefeld serves clients in a variety of industries, particularly the trade, chemical, construction and engineering, energy and financial services sectors. It recently acted in a €100 million project finance dispute and a €18 million case relating to infrastructure and transport sector, both heard at the German Institute of Arbitration (DIS). The latter case led to proceedings before the German Federal Court of Justice.

While all four partners sit as arbitrators, Hanefeld is particularly prominent in this regard. She has received around 80 appointments to hear disputes at the ICC, DIS and various other bodies, including some investment treaty cases.

Hanefeld has lately been chairing an ICC panel hearing a €1.2 billion dispute between German-Austrian consortium SEK and Japan’s Hitachi group over the construction of a power plant in the Rhine. In addition she’s a co-arbitrator in a €230 million energy dispute at the ICC and a a €120 million Energy Charter Treaty claim at the SCC.
