Who's Who Legal Arbitration: Lawyers

Jan Heiner Nedden is managing partner of Hanefeld Rechtsanwälte, a dispute resolution boutique firm based in Hamburg, Germany.

Prior to joining Hanefeld Rechtsanwälte in 2011, Heiner served as counsel at the secretariat of the ICC International Court of Arbitration in Paris for seven years and was in charge of the case management of over 1,000 arbitrations and has scrutinised some 500 arbitral awards.

Heiner frequently acts as chairman, sole arbitrator and co-arbitrator in international and domestic cases, some of which involve state entities or sovereign states. His track record contains several dozen international and domestic cases such as post-M&A, construction and infrastructure, distribution and agency, and machine building disputes, both institutional (inter alia ICC, SCC, DIS, the Danish Institute of Arbitration and VIAC) and ad hoc in a variety of jurisdictions and pertaining to various substantive laws, including German, Austrian, Swiss, Danish, Swedish and French law. Heiner is also an appointed member of the WIPO list of arbitrators.  

Heiner represents clients before arbitral tribunals and in enforcement proceedings, and advises on general and specific issues of arbitration law and strategy. In addition, Heiner regularly serves as party-appointed expert in proceedings before foreign courts, including large scale finance disputes. The excellent quality of Heiner’s work has been acknowledged in several domestic and international rankings.

Heiner is a trained mediator and a lecturer on domestic and international arbitration law at the University of Hamburg (2014), the Summer Academy on International Dispute Resolution at the University of Heidelberg and the Swiss Arbitration Academy in Zurich/Geneva. He frequently participates as speaker at arbitration conferences and is co-editor and co-author of the German-language standard practitioner’s commentary on the 2012 ICC-Rules/1998 DIS-Rules (Verlag Dr Otto Schmidt, Köln, 2014). Heiner is an appointed member of the ICC Commission on Arbitration and ADR, the ICC task force on “The Revision of the Rules of ICC as Appointing Authority in UNCITRAL or other Ad Hoc Arbitration Proceedings”, and the dispute resolution committee of the Danish Institute of Arbitration. He is fluent in English, German and French.

Heiner’s professional background goes hand in hand with the international focus and practice of Hanefeld Rechtsanwälte. The unique background and experience of the firm’s professionals make clients benefit from a particular profound knowledge and familiarity with the perspective of parties’ counsel, arbitrators and mediators, as well as that of arbitral institutions. Hanefeld Rechtsanwälte’s expertise encompasses commercial and investment arbitration. In addition to representing parties before arbitral tribunals and state courts, all members of the firm regularly act as arbitrators or experts on German and international law. The firm also advises on specific procedural issues in arbitration proceedings, provides risk-assessment and strategic advice, and assists parties in enforcement proceedings either as lead-counsel or as co-counsel in cooperation with domestic and international law firms. The clients of Hanefeld Rechtsanwälte include large and medium-sized companies from a variety of sectors and jurisdictions, state entities and sovereign states.

WWL says: Jan Heiner Nedden is “extremely well prepared, appreciative in his work and he really discusses and takes the arbitrator role seriously”.
