From vetting property contracts to filing taxes to defending and winning a case for me; she has done it all with ease and finesse. I highly appreciate her work especially as an investor who’s not grown up in Germany and therefore my grasp of the German language has been very basic. She has been an extremely valuable asset.”
Client from India
“As an Israeli entrepreneur I keep business relationship with Janin more than 10 years. I enjoy her professionalism and quick reaction to changing business situation. Janin succeeded to provide envelope of business services from her partners in Germany (including notaries,real estate brokers,developers in different countries) and Israel,that significantly increase additional value for business . I appreciate so much our deep business relationship during years.”

Her rigorous work attitude, professional dedication, and client-oriented service have fully earned my deep trust.”
Client from China
“I was referred to Ms Ahnefeld by a friend who had previously benefited from her firm’s services. Ms Ahnefeld has been highly responsive, detail-oriented and strategic in handling a complex tenancy dispute involving extensive documentation and cross-border issues. As a non-German speaker, I particularly appreciated her ability to work clearly and professionally in English throughout the process. Her communication has been clear, pragmatic and well-structured, and she was quick to identify inconsistencies in the data.”
Client from Switzerland / France
“Janin supported us through several real estate matters in Germany, including identifying problematic real-estate deals before we committed to them, reviewing the purchase contract for our apartment, and currently representing us in an ongoing legal dispute. Throughout all of these processes, she was extremely professional, detail-oriented, and trustworthy. As foreigners unfamiliar with the German legal system, we especially appreciated her ability to explain complex procedures patiently. Her advice gave us confidence and helped us avoid costly mistakes.”
Client from Israel
“As a British citizen with property interests in Berlin, German business and tax law can often seem perplexing, complex, and difficult to manage. Janin Ahnefeld has helped us to navigate, understand and remain compliant throughout our 10-year relationship with the firm. She is always extremely prompt in replying to messages, she is approachable and she demystifies the rules and regulations so that you can feel confident that you are compliant and working to the best of your abilities.

“Janin Ahnefeld represented me in an exceptionally complex family gift of a flat in Berlin and guided me through every tax and legal challenge with expertise and patience. She also took on the difficult process of evicting a non-paying tenant – no small feat in Berlin – and managed everything so smoothly that I was ultimately able to sell the apartment at the best possible price. What truly sets Janin apart is her personal, well-rounded follow-up care. She doesn’t just handle your case; she stays by your side. We even became friends along the way. I trust her completely and wholeheartedly recommend her and her law firm.”
Client from Ukraine
“I’ve known Janin for more than 15 years, during which time she helped me both acquire and sell multiple properties in Berlin. Beyond legal services, she was instrumental in my dealings with banks and pension funds that partially financed these transactions. Throughout this time, our cooperation and communication were simultaneously easy, enjoyable, and incredibly focused and professional—all this while I spend most of my time in the Far East. I’ve referred numerous friends from Australia, Southeast Europe, and elsewhere, and everyone received the same top notch service. After all these years, I consider her both a friend and a business partner, and I hope to work with her again in Berlin soon.”
Client from Serbia
“I have been working with Janin for almost 10 years for my annual tax matters, and she has always been professional, reliable, and extremely efficient. I always feel that everything is handled carefully and correctly. She provided excellent support with legal and administrative matters related to my apartment, including handling the termination process of a tenant contract after the tenant sadly passed away. Her guidance made a very difficult situation much easier to manage. When I had issues with neighbors complaining about my tenant smoking heavily, she handled the matter calmly and professionally and helped me find the right way to deal with the situation. What I value most is her responsiveness, professionalism, and the confidence she gives me that everything is under control.”
Client from Israel
“Janin Ahnefeld has provided me, since the purchase of my studio in Berlin in 2012, with all the legal assistance and expertise I have ever needed, from tax returns amid changing regulations to the delicate estate settlement that had to be handled with the relevant French authorities following my husband’s passing. All of this with as much professionalism and responsiveness as warm, genuine empathy!”
