Which service method is permitted by registered or certified mail with return receipt requested under ARCP Rule 4.2?

• A. Service by publication
• B. Service outside Arizona
• C. Substitute service
• D. Alternative service

Answer: (B)

ARCP Rule 4.2 envisions a practical, verifiable way to give notice when the person to be served is outside Arizona: service by registered or certified mail with return receipt requested. The return receipt provides concrete proof that the recipient received the documents, which aligns with due process requirements even when personal service isn’t feasible across state lines. This is why service outside Arizona is the method described as being permitted by that mail option. Other methods like service by publication, substitute service, or alternative service involve different procedures or circumstances and aren’t the specific outcome addressed by using return receipt mail in this rule.
