I urge you to work with Legal Advisers who specialize in drafting agreements rather then specialists . Why ? In my opinion it is better to draw up a very good agreement while shareholders are getting along rather then learn that you are being abused at the time of dispute . Make sure your chosen lawyer is taking time to explain to you what if scenarios at the onset and everyone understands the provisions as well as their responsibilities as a shareholder . Being a shareholder of a company carries fiduciary responsibilities and they can not be breached . If you do not have a agreement , call me and I can assist you in finding lawyers that are thorough at creating agreements .
