Hello, Okay. You have to understand that regardless of what kind of corporate entity you set up, the prosecutor may still pursue you if you are an active member and engage in criminal activity (which in this case may be medical trials/activities without proper licensure or authorization). So much like directors/officers/managers at Enron, or Worldcom, or Lehman Brothers, etc, got criminally charged (in those cases under federal laws for corruption, fraud, etc), so can officers/members/directors of such a firm that engages in questionable medical research. So it does not matter which corporate structure you have. Now speaking about CIVIL liability
, the best option is to have an LLC or a S/C-Corp. The problem is that even then, there is no 100% protection. See HERE. It does not matter if you are a partner in name or title
or simply by association. The best way to lack liability is not to have your name on the corporate structure at all. However of course this is next to impossible if you seek some control. THERE IS ALWAYS A RISK OF PERSONAL LIABILITY when associating yourself with a corporate entity, regardless of what kind of entity it is. Even shareholders may be held liable if they have control/command positions. Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty. I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
