- About us -

KKopeć & Zaborowski (KKZ) is among Poland’s leading law firms. In recent years, the firm has been steadily building its position by combining litigation experience with a modern approach to business advisory. Its core areas of expertise include criminal law, in particular white-collar crime “white-collar offences”, as well as business law, commercial law, press law, personal rights protection, and employment law. It is precisely at the intersection of these disciplines that the most complex cases arise: matters requiring not only legal knowledge, but also judgment and business intuition.

One of KKZ’s defining strengths is its ability to operate where cases are anything but straightforward, where success depends on drawing across multiple areas of law. The firm has long conducted forensic audits on behalf of businesses, covering both the detection of internal irregularities and the analysis of operational processes for efficiency and compliance risks. In practice, this means working closely within clients’ organizational structures, often in situations that call for discretion, swift action, and precise recommendations.

KKZ’s clients include some of Poland’s largest private and state-owned companies, as well as prominent public figures: entrepreneurs, journalists, and politicians. This breadth of clientele reflects the nature of the firm’s work: complex, multi-layered cases that demand a strategic approach well beyond standard legal templates.

At the heart of KKZ’s practice are two principles which, though simply stated, require genuine commitment to uphold: delivering the highest quality of service at reasonable cost, and pursuing unconventional legal solutions. The latter is reflected in a team of 70 professionals, including 60 lawyers, who combine litigation expertise with knowledge spanning business, new technologies, and communications.

Over the years, the firm has earned consistent recognition in both international and domestic rankings. Its presence in listings such as Forbes Best Law Firms, Legal 500, Chambers & Partners, Media Law International, and The Lawyer European Awards affirms its established standing in criminal business law, media law, employment law, and litigation. A full list of firm and individual accolades is available under AWARDS.

The managing partners have also distinguished themselves individually. Attorney-at-law Marta Kopeć, who oversees the firm’s strategy in finance, HR, and administration, has been named a Leader in Employment Law in the Rzeczpospolita legal ranking on three separate occasions. She is also recommended in the international Legal 500 ranking. Advocate Maciej Zaborowski is consistently recognized in numerous rankings as one of Poland’s foremost specialists in criminal business law and reputation protection, including personal rights litigation. His practice, like the firm’s work as a whole, centers on cases that demand not only legal expertise, but strategic thinking and the ability to perform under pressure.

Alongside its core commercial practice, KKZ pursues an active pro bono agenda and engages in broader social initiatives. The firm has been recognized for its support of non-profit organizations and international initiatives, demonstrating a commitment that extends well beyond standard market activity. Further details are available under PRO BONO.

Today, Kopeć & Zaborowski is a firm that unites litigation competence with strategic counsel, operating both in crisis situations and in day-to-day business support. KKZ’s history, shaped over more than a decade, is one of growth built on specialization, client trust, and the steady development of a team capable of taking on the most demanding cases. Through an extensive network of international partnerships, KKZ provides comprehensive legal services both in Poland and in cross-border matters.
