Service of Process

State-by-state requirements for serving defendants in foreclosure actions — covering sheriff service, private process servers, certified mail, service by publication, entity service, unknown parties, SCRA compliance, and proof of service.

Statutory Authority — Ariz. R. Civ. P. 4, 4.1, 4.2; A.R.S. §12-401–§12-412; A.R.S. §33-809

Arizona uses registered private process servers as the primary service method — the sheriff is available but rarely used in practice. Private process servers must register with the Supreme Court and be approved by the presiding judge in their county. For non-judicial trustee sales, the trustee must provide notice by certified mail and publication under A.R.S. §33-809.

Service Methods

  • 1Using an unregistered process server — service is void
  • 2Failing to send §33-809 certified mail notice to all required parties in trustee sales
  • 3Missing the 91-day notice period for trustee sales — sales conducted before 91 days are void
  • 4Insufficient documentation of diligent search before publication
  • 5Serving a corporation through the wrong agent or at the wrong address
  • 6Untimely filing of proof of service — file within 20 days of service

County-Level Variations

Sheriff fees vary significantly: Pinal County ($16 + $2.40/mile), Cochise County ($56 flat + $32 process fee), Pima County ($100 deposit), Navajo County ($16 flat), La Paz County ($16 minimum + mileage). Registered process server registration is county-specific — verify the server is registered in the county where service will be made.
