Daniel Toth has joined our team as an assistant in February 2022. He completed his bachelor’s degree in Translation Studies at the University of Vienna. His working languages are German, Hungarian and English.


Due to our family history, our activities mainly cover Austria and Hungary. Thanks to our language skills, we have successfully taken on and represented more and more French-speaking clients in recent years.


Our father, Dr. Géza Simonfay, first founded the law firm “Simonfay & Partner” in Vienna, and one year later in Budapest. He practiced law in Vienna for many years with the law firm “Simonfay, Salburg & Krenn”.


In 2019, we jointly established the company “Dr. Simonfay Rechtsanwalts GmbH”. However, the law firm continues to exist under the name “Simonfay, Krenn & Partner” in cooperation with Mag. Michael Krenn.


For a legal service to be successful, a relationship of trust must be established between the lawyer and his client. Our experience has shown us that a good working relationship is necessary for a successful, efficient and, above all, sustainable solution of the problem. That is why we see ourselves as your partner and solution provider in the legal field. With the support of our entire team, you will receive the necessary legal assistance for yourself or your company, tailored to your situation, so that you can achieve your business goals as quickly and decisively as possible.


In addition to our firm’s specific expertise in Eastern European law and its specialization in business law, we also advise and represent our clients in all matters of Austrian, Hungarian and European law. In this respect, we have extensive experience in civil, administrative and criminal proceedings at all levels of court.


In the course of our more than 30 years of existence, our law firm has, in close cooperation with our clients, been able to resolve a large number of complex national and international legal situations for well-known Austrian and global companies.


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.
