When foreclosure proceedings start in AZ, the first legal notice that is completed is the "Notice of Sale", also known as a "NOS", as the foreclosure process in AZ is only a 90 day process. The NOS MUST be posted to the property within 30 days of the foreclosure process being started. On that NOS is the information for the trustee that is handling the foreclosure. You can call them at any time and provide them with the TS# (also located on the NOS) and they can give you the information.
Please contact me with any other questions or concerns. I managed a trustee dept. in AZ for over 4 years.
