Dr. Géza Simonfay has been practicing law in Austria since 1990. Based on his family background, much of his work focuses on Austria and Hungary. After founding the law offices of “Simonfay & Partner” in Vienna, then a year later in Budapest, followed by many years in Vienna with the “Simonfay, Salburg & Krenn” law firm, he most recently established a new law firm, “Dr. Simonfay Rechtsanwalts GmbH”, with his children, Mag. Anna Katharina Simonfay and Mag. Géza Simonfay-Leon. Together with Mag. Michael Krenn, the firm now continues its work under the name of “Simonfay, Krenn & Partner”.


A solid, trusting relationship between lawyer and client is the foundation for good legal advice. In our experience, working together is the only way to identify successful, efficient, and sustainable solutions to any problem. We are your legal problem-solvers and companions. With the support of the entire team, you get the assistance that is legally sound and makes good business sense to help you achieve your financial goals more quickly and consistently.


Aside from our firm’s specific Eastern European expertise and our specialization in commercial law, we also advise and represent clients in all matters of Austrian, Hungarian, and European law. We have years of wide-ranging experience in civil, administrative, and criminal proceedings, in all courts.


In its over 25 years of existence, our firm has successfully resolved legally challenging situations at the national and international level for leading Austrian and international companies, in close collaboration with our clients.


We are mainly specialized in business and commercial advising. We have extensive experience with M&A, business restructuring, competition law, labor law, commercial transactions, proceedings before ordinary courts and courts of arbitration, company law, tort law, real estate law, copyright law, as well as in the fields of EU law, intellectual property law, representation in cases of medical malpractice, and in the health care field in general. Our work as lawyers is informed by profound knowledge of EU law. Although our clients are mainly domestic and foreign small and medium-sized enterprises, we also represent a number of large companies on a continuous basis.


Another plus point is the multilingualism of our employees. The lawyers and trainee lawyers working in the law firm are fluent in German, Hungarian, French, English, Spanish, Serbian, Croatian and Czech.
