Litigation and arbitration

The litigation and arbitration practice at act BSWW legal & tax is made up of experts whose knowledge and experience have been recognised by international legal directories, such as Chambers Europe and The Legal 500.

We focus on comprehensive protection and balancing of the client’s interests before, during and after a dispute is resolved, minimizing the risk of similar problems arising in the future. At the pre-litigation stage, and whenever necessary, we come up with alternative dispute resolution methods, often through negotiation and mediation. Thanks to that, we are often able to avoid long-lasting and costly court proceedings.

If a case goes to court, we rely on a well-conceived litigation strategy based on an extensive analysis of applicable circumstances. We are well aware that litigation frequently forms just a part of a complex economic reality, which is why we offer comprehensive solutions to protect our clients’ interests to the greatest extent possible.

Among our clients are entities operating in the residential, retail and office sectors of the construction/development industry. In addition, we advise companies that provide air and rail transport services, as well as ones operating in the pharmaceutical, automotive and petrochemical industries.

Our firm is a co-founder of act legal, an alliance of leading independent law firms, with presence in Poland, Austria, the Czech Republic, Germany, Italy, Hungary, Romania, Slovakia and the Netherlands.  Extensive international cooperation and the vast experience of our colleagues in other countries enable us to successfully provide legal services to our clients outside Poland. Presence in the Italian market is one of our distinctive elements. We represent clients in proceedings before the courts in Italy. We also consult Polish clients on disputes against Italian companies.


Scope of legal consulting

We represent Polish and foreign clients before common courts of law, administrative courts, the Supreme Court and arbitration courts in disputes related to:

  • Real estate transactions;
  • Construction law;
  • Energy law;
  • M&A transactions;
  • Corporate matters;
  • Employment law;
  • Aviation law.

Our team offers customized legal assistance in restructuring and bankruptcy proceedings, while also handling a significant number of tax disputes. We also handle selected white-collar crimes cases, acting as counsel for the defense or the victim’s attorneys, especially in fiscal cases and ones related to on-the-job accidents.
