The Act requires an applicant to submit a written application. § 10-614(a). However, if a request is made for a type of record that has been designated by the official custodian to be made immediately available on request, there is no need for a formal written request. § 10-614(a)(2)(i); see also PIA Manual, at 10. As a practical matter, some records may be obtained by oral request, and many agencies permit oral requests.
