Commercial Court

Commercial Court

Maricopa County Superior Court first established Commercial Court in 2015 as a pilot program initiated by the Arizona Supreme Court. Because of the success of the pilot program, as of January 1, 2019, Commercial Court became a permanent feature of the Superior Court. Commercial Court is a venue within the Civil Department to resolve controversies that arise in commercial settings expeditiously and to reduce the expense of litigation.  

Commercial Court cases are governed by Rule 8.1. The January 1, 2019 amendments to Rule 8.1 apply to all commercial cases commenced on or after January 1, 2019 and to all commercial cases pending before that date, except the $300,000 minimum in amended Rule 8.1 (c) does not apply to cases pending before January 1, 2019.

Any cases that were filed before July 1, 2015 will not be eligible for transfer to Commercial Court.

  • Commercial Court Decision Repository – Please note that you will need to have Westlaw access to use the repository. Also, several decisions predate the formation of the Commercial Court on July 1, 2015. The repository will be updated as decisions are issued by the Commercial Court judges.
  • Please note that Commercial Court cases filed in the Court's Northeast and Southeast facilities will be assigned to one of the four Commercial judges, all of whom work downtown. If you file a Commercial Court case in either Northeast or Southeast and need an emergency hearing (e.g., a Temporary Restraining Order or a Preliminary Injunction), you will have to call 602-506-1497. The court staff who answers the call will give you the name of the assigned judge and direct you to the judicial officer's division assigned to your case.
