Stakeholder Input
The purpose of this site is to share information about the committee's meetings, progress, and work product as well as gather constructive comments from stakeholders.

As with all court committees, these meetings are open to the public. Time is reserved on the agenda for public comment. Each member of the public who wishes to share ideas for improving the tentatively approved guidelines may speak for up to three minutes.

Stakeholders may also participate by submitting productive comments on this site. Unlike a forum or a chat room, this site does not allow for direct response from the committee. Comments should be focused on the tentatively approved guidelines (above, updated June 22, 2010); and how they can be improved. The committee cannot discuss or offer assistance with any individual child support matter.

Submissions will be reviewed periodically by the site moderator. The site moderator will screen the submission for duplication, irrelevancy, spam, harassment, profanity, obscenity, or other inappropriate content. Comments that pass moderator review will be posted for public viewing; all others will be rejected.

Written comments for the Arizona Judicial Council meeting to be held on October 21, 2010 must be submitted no later than close of business on Tuesday, October 5, 2010.  Comments received after this date and time will not be included in the materials sent to the Council members to review.
