As a criminal defense lawyer, I advise and defend your interests as individuals and companies exclusively in criminal and misdemeanor law, both in preliminary proceedings and in the main hearing in court. This includes in particular the quick reaction in case of arrests, searches, seizures and interrogations by the police and the public prosecutor’s office. Therefore, I have many years of experience as a criminal defense lawyer. Through participation in numerous criminal trials in all instances, I have a distinctive expertise as a specialist lawyer for criminal law and also accompany companies in the area of preventive advice and in compliance issues.

„At this point, I would like to express my great praise and recommendation to Dr Nassif. He represented me in a criminal case regarding two different charges, which were ultimately dropped thanks to good cooperation and his professionalism. I have been defended by many lawyers in my life, but none has been as accessible and communicative as Dr Nassif. In addition to his legal expertise, he is also an extremely friendly and down-to-earth person. This is how defence should go hand in hand with the client. Great!“

Dan B. P. from Düsseldorf

„An unbelievable accusation was made against me by the public prosecutor’s office: predatory extortion. Dr. Nassif persuaded me to make a personal statement to the police in Mannheim. There, in 4 hours of interrogation, accompanied by Dr. Nassif with his very calm and fully understanding of the case, I convinced the public prosecutor of my innocence. Shortly thereafter, I had the discontinuation order.“

Matthias H. from Frankfurt

„Dr. Nassif is always committed, very friendly and open. He is a great lawyer and can only be recommended!“

Aysgiel T. from Essen

„Dr. Nassif supported me mentally in prison very much and made up for the mistake of the justice system.”

Kaya G. from Velbert

„I was accused of having sexually abused my brother’s son several times; no one wanted to believe me and I was in pre-trial detention for several months. Dr. Nassif made sure that I was acquitted at the Essen Regional Court. My family and I are eternally grateful to him.“
