If it is a small amount of money, I would just chalk it up as a loss and move on.
Unless it is a small claims case, you you simply don't "file" a case. In such inferior courts, they may have the "fill in" form, true.
If in a superior court YOU need to format your own complaint, causes of actions, caption, etc. They may provide a civil cover sheet, but it is NOT a complaint.
Small claims cases for out of state parties may not even be permitted to be filed? That you would have to check. A Superior court may be the only method. Small claims, generally, state specific, have a jurisdictional limit of $7,500.00. I did not check for AZ.
Municipal courts, X TO X amount, say from over small claims up to 15-25 thou., and State courts over the municipal jurisdiction.
