Ariz. Rev. Stat. § 19-205 – Signatures and verification

A. Every qualified elector signing a petition for a recall election shall do so in the presence of the person who is circulating the petition and who is to execute the affidavit of verification on the reverse side of the signature sheet. At the time of signing, the qualified elector shall:
1. 1. Sign and print the elector's first and last name.
2. 2. Write in the appropriate spaces following the signature the elector's residence address, giving street and number or, if the elector has no street address, a description of the elector's residence location, and the date on which the elector signed the petition.
B. The person before whom the signatures were written on the signature sheet shall in an affidavit subscribed and sworn to by that circulator before a notary public verify that each of the names on the sheet was signed in the circulator's presence on the date indicated, that the name and address were printed by the signer on the date indicated and that in the circulator's belief each signer was a qualified elector of the election district on the date indicated in which the recall election will be conducted. All signatures of petitioners on a signature sheet shall be those of qualified electors who are registered to vote in the same county. If signatures from more than one county appear on the same signature sheet, only the valid signatures from the same county that are most numerous on the signature sheet shall be counted.
