and experienced

As the founder of the law firm of Klötzer-Assion, I can draw on many years of legal experience to assist you. As I have also worked as an investigator, I am very familiar with the structures and procedures of law enforcement agencies and the courts. 

Focal points



to you

My priority is efficient analysis and a highly professional, results-oriented approach to ensure consistent implementation of your options. I consider your concerns not only from the perspective of criminal law: I will also work with you to develop a comprehensive solution for your economic and personal situation.

fields of law




I set myself the highest standards in my work. Continuous training is as much a matter of course for me as regular participation in scientific debate via specialist publications and lectures. My expertise will be focused upon your particular case.

Where a question arises that is outside my area of practice, I have a constantly growing network of business lawyers, tax advisers, and experts in customs and export law to ensure that you receive excellent advice.
