I went to law school to do that, but without that you can start by focusing on an area of law called "business associations/corporations." There are resources online to assist law students studying for exams in that class so you can use those to get a grounding in the concepts of agency law and partnerships.

From there you can start to specialize in more specific structures by examining the filings of public companies or scouring the web to figure out how a particular fund you are interested in is structured.

To let you know, it is further complicated in US law by each state having different corporate rules. If you go with Delaware or New York it's probably your best bet for public, but closely held or private companies could be anywhere. As a starting place, most states adopt the Revised Uniform Partnership Act, or RUPA - that is available online through law.cornell.edu
