Provinces, not states, in the DR.
But I doubt that you are going to find what you are looking for on this board. There has been discussion about some specific provision in a law that related to a problem some member was having, or Fabio Guzman, the attorney who answers questions in the Legal section of the message board sometimes mentions a specific law or portion of a law in answering a question posted in that section, but I am not aware of any organized body of information in the archives of dr1 regarding laws of Sosua, etc.
If you go to Fabio Guzman's website you will find a number of publications that contain laws and information about laws. Perhaps some of what you are looking for is in one of them.

Otherwise, I would suggest that you repost your question , asking Fabio where you can find what you are looking for. Try to be a specific as you can.
