What clients say about our work.

Philipp Stern
Philipp Stern Managing Director, Stern & Schatz GmbH

„ab&d Rechtsanwälte have been advising us on commercial law matters for over 10 years. We have always been able to rely on highly competent advice and great commitment, with economic considerations never being overlooked. The advice was given in a way that avoided litigation wherever possible – but when unavoidable, every resource was deployed, resulting in several court successes together.“

Andreas Jetter
Andreas Jetter Managing Director, Apaloo GmbH

„Competence and a healthy attitude! We received a cease-and-desist letter back in 2010 and have had the firm by our side ever since. It is no exaggeration to attribute part of our success to their work – in trademark and patent proceedings as well as various court cases, we have always received highly competent advice with honest and realistic assessments.“

Ana Maria Alvarez
Ana Maria Alvarez Founder, MigrationHub and Migrapreneur

„Coming from another country to do business in Germany requires trustworthy individuals guiding you to success. And that's what Tobias, Norman, and his team represent for many of us, their clients. People willing to go beyond their daily-basis business and routine to be that lifesaving advice many of us are seeking for.“

Konrad Knops
Konrad Knops Founder, Bone Brox GmbH

„After founding Bone Brox GmbH, the lawyers at ab&d – especially Tobias Bystry – supported us hands-on in all matters of competition law and corporate law. Particularly noteworthy – they do not just negotiate and draft contracts, they always think commercially too – so we received not only legal advice but also valuable tactical and strategic input.“

We engaged this firm to assist with the incorporation of the company in Germany. Throughout the entire process, the team handled every task professionally and efficiently, coordinating closely with notaries, the commercial register, the transparency register, and banking partners to get everything finished on time. Communication was clear, response times were fast, and we always felt in good hands. The final result was exactly what we needed. If you are looking for legal support for company incorporation or corporate matters in Germany, we would not hesitate to recommend ab&d legal.

My special thanks go to Dr. Joanna Koronkiewicz, who handled my case with the utmost professionalism and explained the finer points of German competition and trademark law relevant to my case in a very understandable and friendly manner. Professionalism at the highest level.

★★★★★ May 2026

I had an excellent experience working with this law firm while setting up the official documents for my agency. From the very beginning, they demonstrated a high level of professionalism and attention to detail. What stood out most was their genuine effort to fully understand my business concept before proceeding with any paperwork. They took the time to ask the right questions and ensured that every document was tailored specifically to my needs. I first contacted them at the end of 2025, and by the beginning of 2026, everything was completed efficiently and without any complications. Dr. Joanna Koronkiewicz thorough approach gave me great confidence that all legal aspects were properly handled. I highly recommend this firm to anyone looking for reliable, knowledgeable, and dedicated legal support.
