Though this is not really a tax question (i.e., there is no right answer), I do have some thoughts on this. Basically, this is no different than the due diligence you should do for any investment. As a passive investor, you have little control over fund compliance, just like you would have no control over whether or not a public mutual fund is SEC compliant. Thus, I would suggest at a minimum that you do business with a "trusted" organization. Here are some examples of what that means to me. A well-established reputable firm should have a track record of success, compliance, etc. Due diligence should be conducted on the people involved with the executive and fund management. What are their backgrounds, proven history, other organizations worked with? How did you come to know about the fund? A referral from a knowledgeable trusted resource? A better business bureau profile is good. What are their assets under management? Who is their insurance company? These are just some items that you may consider in your due diligence. None guarantees anything, but if the firm is well-known, rated high, insured, etc., there may be some legal recourse if they fail their compliance.
