M&A partners Peter Daszkowski, Krzysztof Rastawicki and Siegfried Seewald and tax partner Lidia Dziurzynska will join Beiten Burkhardt before the end of April. A number of associates will go with them.
The Beiten Burkhardt office, which will have six partners with the new arrivals, focuses on M&A and real estate.
Beiten Burkhardt managing partner Jack Schiffer says: "The recruits will give us critical mass, increase our client base and increase our tax capability."
The moves follow the merger between Clifford Chance and Pünder Volhard Weber & Axster at the beginning of last year.
Clifford Chance managing partner Nick Fletcher says: "The partners want to work for a small German firm. It's disappointing but I understand it. They want to work purely serving German clients."
Schiffer claims that since the merger the two firms have failed to integrate and the Warsaw practice is run as two separate offices.
He says: "The merger has not been an improvement. The team feels that long-term referrals and clients are not willing to accept the increased fees. They felt that they couldn't serve their Pünder clients because of the high-fee requirements that have been imposed on them by Clifford Chance," he says.
The loss of four partners will halve Clifford Chance Pünder's capacity in Warsaw.
Fletcher says the Warsaw office will be recruiting during the next few months and a partner will relocate from Germany in the summer.
