As a paralegal, the form that I use most often is probably AO 88A, which is the subpoena duces tecum or subpoena to produce documents form. I have prepared a Word version of the form that is available for download at https://drive.google.com/open?id=0B6Zj-oo4RdabcGhHUnQ1VnhWMWc. This document is a Word template, and it includes a dropdown list of all of the United States District Courts. The template will help avoid accidentally saving over the original blank form as you create a new subpoena document.
Please review the form to ensure that all of the information contained in it accurately reflects all of the required information prior to using it in litigation.
If you have any questions about the form or suggestions for additional blog topics, or if I might be able to help you in some way, feel free to email me at blauney@gmail.com.
