Virtual Consultation Available
I am licensed to practice law in both Germany and the U.S. (California). I had practiced law in Germany, where I was born and raised, for almost a decade already before relocating to the United States. As a result, I am not only very experienced with both legal systems, and connecting both worlds, I am also intimately familiar with both societies, they way both countries function, and the cultural differences.
In addition to that, I handle cases in courts in both countries on a regular basis, and I represent clients in courtrooms in Germany and the United States, which is a unique set of qualifications, skills, and experience in German-American law.

"Mr. Siegwart is the attorney to call on for transnational legal issues involving US law, on one hand, and German/Austrian/Swiss law, on the other. I'm an attorney and I sought his advice on an issue that arose in a probate proceeding in Vienna. Austrian counsel was stuck on a choice of law issue, and Mr. Siegwart was familiar with the problem and gave us expert counsel on how to break the log jam we were facing."
