a. Caption. A “caption” is a heading at the beginning of a document. The first page of every document that is filed with the court, including a pleading as defined in Rule 107(a), must include a caption that contains the name and address of the court where the document is being filed; the names of the parties; the mailing address of the party who is filing the document, and the party's e-mail address if the party has one; and the name of the document. Every document filed with the court after the complaint must also include the case number assigned by the court. See Rule 112(a) concerning the case number. The court may refuse to accept a document that does not meet the requirements of this paragraph. [ARCP 10(a)]

b. Format. A party must file a document with the court on paper, except that a party may file a document electronically if the court has electronic filing available. These rules apply to both electronic and paper filings. Electronic filings must be in a format allowed by the court. Paper filings must be on only one side of white 8.5 x 11 inch paper, with one-inch margins on the top, bottom, and sides of the page. Documents filed on paper must be typed, printed, or legibly handwritten. Documents filed on forms provided by the court do not need to meet these requirements. The court may issue documents such as notices or orders in either paper or electronic formats. [ARCP 10(d)]

c. Attachments to documents (“exhibits”). Exhibits may be attached to a document that is filed with the court. An exhibit is considered a part of the document to which it is physically or electronically attached, and an exhibit does not require a separate caption. [ARCP 10(c)]

d. Sensitive data. A party is responsible for assuring that a document or exhibit that is filed with the court does not include a person's social security number or a financial account number, or if a number is necessary, that it includes only the last four digits of the number; and the court may impose penalties on a party for a violation and to ensure future compliance with this requirement. [ARCP 5(f)]

e. Filing documents. The original of every document must be filed with the court, but attachments to documents that are filed with the court may be copies. Documents are filed with the court when they are delivered to and accepted by the court. [ARCP 5(h), 10(d)]
