Nevada "Who's on First..."

Is anyone here truly certain about the "due and proper, legal course of process" (timelines, notices, recordings, etc...) as it relates to the tranfer, substitution and assignment of "legal right to ownership" (Trustees, Beneficiary's and Deeds of Trust) prior to Notice of Default in Nevada?

I have been on a continuous search for several months, and not a single source has been able to describe in any detail, how the filings must be "perfected" (including any Attorney, even those running for election to Attorney General).

I am interested in understanding the process, just as a contractor understands and follows "due course" to "perfect" rights to utilize the state "Lien Laws" in order to rightfully have position to collect or attach a "real property". 

Anybody?
