Ariz. Rev. Stat. § 44-7051 – Consumer protection

A. Nothing in this chapter diminishes the parties' consumer protection rights prescribed in chapter 10, article 7 of this title or any other federal or state law relating to consumers.
B. If a consumer law, other than this chapter, requires a paper record or notice of the transaction, the parties to the transaction may request that the record or notice be provided in an electronic format and that record or notice shall comply with this chapter. Even if before completing a consumer transaction by an electronic method that complies with this chapter, a party to the transaction requests that a record or notice of the transaction be delivered in electronic form, that party may subsequently change that preference and request that all future records or notices relating to that transaction be sent in paper form to an appropriate address. Withdrawal of consent does not affect the enforceability of electronic records or notices previously provided or made available to that party in accordance with this chapter.
C. A nonelectronic consumer contract or agreement may not contain a provision that authorizes any transaction or part of any transaction pursuant to that contract or agreement by electronic means unless all of the following apply:
1. 1. The consumer makes a separate and express assent or signing either manually or electronically that specifies that the consumer agrees that certain transactions or parts of transactions will be conducted by electronic means.
2. 2. The contract or agreement indicates which transactions or parts of transactions that may be conducted by electronic means and the manner in which those transactions or parts of transactions shall be conducted.
3. 3. The consumer agrees, as part of the assent, to provide the other party with the consumer's electronic address that complies with section 44-7015.
4. 4. The consumer agrees, as part of the assent, to notify the other party, either manually or electronically, of any change in the electronic address prescribed in paragraph 3 or the consumer's withdrawal of consent to electronic transactions.
