The single best resource I have found regarding navigating the morass of legal jargon in NY is an out-of-print Nolo book called "The New York Landlord's Law Book." It's a bit dated at this point, but I have personally found it very useful addressing some of the topics you've mentioned. It's VERY thorough.
I am sure there are other resources online, but none I have found dive as deep as the above book.
@Nick Spacavento It's not easy reading. You have to search for your topic.
NY landlord - tenant laws - http://public.leginfo.state.ny.us/lawssrch.cgi?NVL...
Many New York State landlord/tenant regulations are jurisdiction-by-jurisdiction (in practice, if not statute), rather than state-wide. A local landlord/tenant lawyer, or local landlord association, may be good resources as well. Or attend a few sessions of your local landlord/tenant court (better than tv lol!).
@Harriet Baldwin I could only imagine the scene that must be!
@Thomas N. Thank you for your help I will be divulging
@Wesley W. I have found a new book by Nolo " Every Landlord's Legal Guide" seems to give me a good idea for what I am looking for. Obviously not perfect but a good way to learn and to understand what I am talking about.
