How Did Dubois & Partners Begin?
Dubois & Partners continues the tradition of the Lawyer Service Pociej & Dubois, Borowski & Warfołomiejew law firm, established in 1990. In 1995, following a generational change, young lawyers Jacek Dubois and Aleksander Pociej—both trained at Lawyer Service—took over. Pociej remained with the firm until October 2011. It was among the first legal entities founded in the early years of Poland’s economic transition, offering not only traditional legal services to individuals but also comprehensive legal support for both Polish and international businesses.
What Is the History of Dubois & Partners?
In July 2017, after attorney Krystyna Pociej-Gościmska (founder of Lawyer Service) left the firm, it was renamed Dubois, Kosińska-Kozak. Ownership passed to attorney Jacek Dubois and legal advisor Elżbieta Kosińska-Kozak, who had joined the firm in 1998. In January 2018, new partners came aboard, prompting another name change to Dubois, Kosińska-Kozak & Partners. Since January 2019, the firm has been operating under its current name: Dubois & Partners Law and Legal Advisors Firm.

Dubois graduated in law from the University of Warsaw in 1986. A former member of the Independent Students’ Association, he completed his legal training and passed the bar exam in 1990. He started his practice in a Warsaw law office and became a partner in 1995.
Who Were His Ancestors?
Jacek Dubois is the great-grandson of Mieczysław Dubois, a legal advisor to Warsaw’s Industrialists’ Fund; grandson of Stanisław Dubois, a parliamentarian in the Second Polish Republic; and son of the legendary attorney Maciej Dubois, a judge on the State Tribunal (1989–1991), Dean of the Warsaw Bar Association, and a defense attorney in political trials.
