In Arizona, an individual must have the consent of at least one party to a conversation in order to legally intercept a wire or electronic communication, including wireless and cellular calls. Otherwise, this conduct is a felony. Ariz. Rev. Stat. Ann. § 13-3005. Utilizing a device to overhear a conversation while not present, without the consent of a party to that conversation, is also a felony.
Under the statute, consent is not required for the taping of a non-electronic communication uttered by a person who does not have a reasonable expectation of privacy for that communication.
