Wolf Theiss


When it comes to arbitration proceedings, knowing the law is sometimes not enough; you need a team which knows the rules and which knows the major players in the field. This is a huge advantage when it comes to choosing the right arbitrator and maximising your chance of success.

The Wolf Theiss Competence Centre for Arbitration in CEE/SEE consists of experts across our 13 offices acting as counsel in domestic and international arbitration proceedings. Additionally, team members have specialized expertise in industry sectors such as energy or construction and infrastructure, and fields such as post M&A disputes. The benefit for you? Seamless service and the necessary specialized industry and legal expertise to meet your business needs.

We can assist with all aspects of arbitration: from drafting and reviewing your arbitration clauses, representing you before arbitral tribunals, liaising with legal or other experts, to handling arbitration-related court proceedings. You benefit from our wide network of contacts in the international arbitration community and our inside perspective on the different legal systems in major arbitration centres across the world.

Members of the team have been engaged in and closely cooperate with international and regional organizations dedicated to arbitration, such as the International Court of Arbitration of the International Chamber of Commerce (ICC), the Vienna International Arbitral Centre (VIAC), the Energy Arbitration Court in Hungary, the Ljubljana Arbitration Center (LAC), the Arbitration Court at the Bulgarian Chamber of Commerce and Industry (AC at the BCCI), the Arbitration Court at the Polish Chamber of Commerce in Warsaw (SAKIG) and the Lewiatan Arbitration Court in Warsaw (SAKL).

Areas of Specialisation

Commercial Arbitration

With a team throughout the region, we have the knowledge and capacity to represent you as counsel and advise you on all aspects of domestic and international commercial arbitration proceedings. Many of our cases involve cross-border elements, meaning you benefit from the advantages of our international network of offices and our ability to deal with multijurisdictional issues effectively. We have experience acting under major arbitration rules, such as UNCITRAL, ICC, and LCIA, as well as those of the national Arbitration Courts attached to the respective Chambers of Commerce in the CEE/SEE region, and in ad-hoc arbitration proceedings.

Investment Treaty Arbitration

Whether you are an investor or a sovereign state, we can assist you in resolving disputes that arise under bilateral and multilateral investment treaties, and have experience acting under both the ICSID and UNCITRAL Rules. Prevention is better than cure. If you are an investor, we can also advise you on the structuring and restructuring of your overseas investments to secure investment treaty protection. We have particular expertise in relation to disputes in the CEE/SEE region and beyond, including Turkey and the Middle East.

Arbitration-related Court Proceedings

We represent you in all court-related arbitration proceedings; including obtaining interim injunctions to protect your assets both before and during arbitration, representing you in setting-aside proceedings as well as advising on the recognition and enforcement of arbitral awards. Where enforcement looks like being particularly difficult or time-consuming, or when assets are split between several countries, our asset tracing experts help identify the most strategically important jurisdictions for you. Learn more about our Litigation practice.

Energy Arbitration

Energy is a complex sector; characterized by high investment costs, long-term contracts and state involvement. The stakes are high and consequently, investment treaty arbitration under bilateral or multilateral treaties – especially the Energy Charter Treaty – is common. To be successful in energy arbitration proceedings you need a team which understands and deals on a daily basis with the complex regulations of the energy industry, and which also knows the ins and outs of arbitration proceedings. Our team does both. Learn more about our Energy & Natural Resources practice.

Construction & Infrastructure Arbitration

In today's globalized world, and particularly within the EU, large construction and infrastructure projects usually have an international or regional context. Due to the scale and complexity of such projects, disputes when they happen tend to be multi-party and multi-tier (i.e. have several dispute resolution 'stages' before arbitration, such as DAB proceedings). In addition, disputes rarely centre 'only' on legal questions; a sound knowledge of the industry itself is essential. Our construction experts are qualified as engineers or certified FIDIC-Adjudicators and have direct industry experience. This, together with the regional coverage of Wolf Theiss, gives us and - more importantly - you an unbeatable advantage. Learn more about our Construction & Infrastructure practice.
