It seems you are putting the cart before the horse. Has the Probate been closed? If not, I'd recommend you work with a Probate attorney to get this done in an efficient, lawful and expedited manner. See Avvo.Com under Find-A-Lawyer and enter Probate / Phoenix AZ. Good Luck!
The probate clerk in Maricopa County is extremely helpful and will probably know if the disclaimers need to be recorded as well as attached to the Affidavit.
Please note that I am answering this question as a service through Avvo but not as your attorney and no attorney-client relationship is established by this posting. An attorney-client relationship can only be established through signing a Fee Agreement and paying the necessary advanced fees.
This is a very state specific question and needs to be addressed by an AZ lawyer. I recommend you go the AAEPA website and locate a qualified law firm in your area to assist you. It doesn't appear as if the cost will be significant, and the protection will be worth significantly more.
