Yes, you need a securities attorney. When you were selling interests in a fund, you are selling securities. If you are selling securities, your offering must be registered or exempt from registration. Each securities exemption has its own set of rules regarding such things as disclosure requirements, financial qualifications of investors, and whether you can advertise. A securities attorney can help you determine the appropriate exemption for your OZ fund offering. The appropriate offering documents may include a disclosure document such as a private placement memorandum, an operating agreement for your company, a subscription agreement, and securities notice filings with federal and/or state securities agencies.
