How we can help

How we can help.

Our support

The need to pursue claims or defend against third-party claims can arise even in the best-managed companies. Imperfect contracts, insufficient security, miscalculated costs, extraordinary changes in circumstance or economic crises can all end up in court.

We are thorough

We delve into the business conditions and rules that govern your business and industry. We always strive to thoroughly understand the subject matter of the dispute.

We act strategically and we are committed

We develop a comprehensive litigation strategy and update it on an ongoing basis. We prepare thoroughly for hearings and ensure active participation in all litigation activities. Your case is our case.

We think comprehensively

When developing and implementing a litigation strategy, we consider the consequences of our actions not only within the dispute itself, but also beyond it. We protect your trade secrets and image.

Demanding clients appreciate us

We advise demanding clients, including financial institutions. Our work is appreciated by them, which is reflected in the prestigious Legal 500 ranking, in which we have been continuously awarded since 2019, among others, in the category of Dispute Resolution. The quality of our work, our excellent understanding of our clients’ business conditions and the litigation strategies we propose are highly valued.

Experience

Knowledge backed by real projects.

Conducting disputes concerning derivatives

We represented one of the largest banks in Poland in dozens of disputes with entrepreneurs concerning derivatives, including a number of proceedings before the Supreme Court. The legal arguments we developed were accepted by the Court of Appeal and the Supreme Court, shaping a favourable line of jurisprudence for our client.

Defending the client's interests in a dispute over agency commission before the CJEU

We represented one of the largest banks in Poland in a dispute with a former agent over commission claims. Our representation also included participation in proceedings before the CJEU in connection with a preliminary ruling.

Representation in consumer disputes concerning financial instruments

We advised and represented financial institutions in dozens of disputes with clients – investors. The disputes concerned financial instruments offered for investment purposes.
