In Arizona civil proceedings, motions and related papers must be served on all parties to the case. Under Arizona Rule of Civil Procedure 5, most in-case documents can be served by mail, hand delivery, or electronic means — but certain motions require personal service.
Emergency motions, TROs, and initial motions to parties not yet appearing in the case require personal service by a process server.
Once a party is represented and has appeared, motions can typically be served via mail, email, or eService per the court's rules.
Hearing notices on motions must be served sufficiently in advance to allow the opposing party adequate time to respond.
OSC hearings on contempt or other emergency matters require immediate personal service with documented proof.
