Hanefeld Rechtsanwälte


HANEFELD is a boutique law firm specializing in Dispute Resolution with a particular focus on International Arbitration and Litigation with offices in Hamburg and Paris.

Dispute Resolution

We act as counsel and arbitrator in international commercial and investment arbitrations, in addition to conducting litigation, acting in DAB proceedings and other alternative methods of dispute resolution, and acting as legal experts. In all matters, our priority is to maintain a clear partner commitment and to provide the personal attention our clients’ cases require, while monitoring, managing and resolving disputes quickly and cost-effectively.


While boutique in size, our broad international professional experiences have equipped us with the legal, linguistic and inter-cultural skills needed to effectively manage large-scale cross-border disputes. Our clients are based all over the globe. The cases on which we work are based in a variety of jurisdictions. The applicable laws in these cases also differ. While many cases have at least some German law implications, we conduct with increasing demand cases governed by international or other domestic laws.


The exceptional quality of our work is valued by clients and colleagues across the globe and has been consistently recognized in national and international rankings. Our experience and expertise combined with a solutions-oriented approach allows us to achieve optimal and efficient outcomes for our clients in complex arbitrations and litigation.

Practice Areas

We have extensive experience and expertise across a range of practice areas and industries, including Construction & Engineering, Energy, Post-M&A & Corporate, Commerce & Trade, Antitrust Damages, Banking & Finance and Foreign Investments.


Our boutique structure allows us to act in matters in which other firms are unwilling or unable to act due to conflicts of interest. Our clients also benefit from having access to our high-quality international dispute resolution network.


We regularly involve ourselves in academic assignments, which include publications, lecturing and speaking engagements in the field of dispute resolution at both domestic and foreign universities. While these activities allow us to give something back to the legal and business communities, they also ensure we remain up-to-date with developments and can keep our clients abreast of the latest changes and trends in the field of dispute resolution.

Unique 360° approach

Our clients benefit from our ability to draw from perspectives and experiences acquired acting as party counsel, arbitrators, mediators and legal experts, as well as from our engagements with arbitral institutions.

Dr Johanna Büstgens appointed DIS40 Co-Chair

Dr. Johanna Büstgens was appointed as the new DIS40 Co-Chair.

The DIS40 is an initiative of young arbitration practitioners, which the German Arbitration Institute (DIS) launched in summer 2002. It offers a forum for the exchange of experience between young arbitration practitioners and deals primarily with topics of interest to younger lawyers.

The five Co-Chairs manage the daily business of the DIS40, plan the bi-annual federal events, support the regional coordinators in the organisation of the regional events and organise the cooperation with the DIS. In addition, they coordinate the activities of the DIS40 abroad and in cooperation with the other foreign "below 40" groups within the framework of the Co-Chairs' Circle.
