Plain-English Summary
Rule 20 is the formatting rule, and it is more specific than most states'.
The caption
The first page of every document must contain a caption detailing the county, state, parties, and title of the document. Fictitious names are allowed where a party's name is unknown, and the pleading must be amended when the true name is discovered.
The format
Nine requirements:
- black text on plain white, and all documents filed must be single-sided;
- at least 13-point type. The court prefers proportionally spaced serif fonts — Times New Roman, Bookman, Century, Garamond, Book Antiqua — and discourages monospaced or sans serif fonts such as Arial, Helvetica, Courier or Calibri. Footnotes must also be at least 13-point and must not intrude into the bottom margin;
- pages 8½ by 11 inches;
- margins at least one inch top and bottom, and between one inch and 1½ inches on each side, with a page number in the bottom margin of every page but the first;
- handwritten documents must be legible;
- typed text double-spaced;
- unless filing electronically or including attachments, only originals may be filed;
- court forms from the court or a court-authorized vendor may deviate, but must be single-sided, and forms from the superior court, Supreme Court or an authorized vendor are deemed compliant;
- interstate forms prescribed by the United States Secretary of Health and Human Services under the Uniform Interstate Family Support Act comply, may be copies rather than originals, and certified foreign orders or sworn statements of arrears may also be copies if they bear an official seal.
Electronic filing
Subsection (c) sends the form of electronically filed documents — format, file type and size, exhibits and attachments, hyperlinks, bookmarks and originals — to Arizona Code of Judicial Administration § 1-901, which is not carried on this site.
Rule 20 has been amended more often than any other rule in Part I; its Credits record changes in 2022, 2023, 2024 and again effective January 1, 2026.
