Corporate and business disputes

We have many years of litigation experience in representing clients in civil and business disputes before common courts of all instances and the Supreme Court and arbitral tribunals in Poland and abroad.

We advise Polish and international companies and individuals in proceedings before public administration bodies, administrative courts and in criminal proceedings before law enforcement authorities and common courts.

We specialize in litigation, especially in complicated, multi-faceted and often controversial cases. We represent clients in litigation requiring the multiple disputes to be carried out at the same time in different jurisdictions, or involving tens of court proceedings at once throughout Poland, including bankruptcy and criminal proceedings.

We help our clients assess the litigation risk and prepare the optimum strategy to manage this risk.

We help our clients in litigation conducted abroad, in cooperation with close to 100 foreign law firms with which we have regularly cooperated for over 10 years as part of the GLOBALAW association.

  • We take a comprehensive approach to every problem.
  • We analyze the legal problems our clients have encountered and, before they make a decision on whether to take a matter to court, we assess the ability to resolve the dispute and help them mitigate the risk associated with the dispute.
  • We advise clients about the prospective benefits or adverse consequences of the steps and legal actions to be undertaken.
  • We assess the information and documents in the client’s possession, in order to prepare the best litigation strategy.

As part of the latter proceedings, we represent clients seeking to obtain the required regulatory consents, and in proceedings involving sanctions imposed by the regulator.
  • We advise our clients and represent them in complex criminal procedures concerning the protection of business activity and the criminal liability of collective entities.
  • We cooperate with US and UK law firms in matters associated with applying US and UK anticorruption regulations.
