When you are preparing an argument or trial brief, you must cite all facts stated, including those from sources such as the transcripts of depositions given in a trial. The Bluebook style manual offers clear guidelines for the citation of trial transcripts. According to Bluebook, all assertions based on deposition transcripts must be cited parenthetically within the text.
Step 1
List the last name of the person testifying. For example: Smith. List the abbreviation for the type of source material. When citing a deposition, write this abbreviation after the name: Dep. List the page number on which the information appears, followed by a period.
For example: 19.
Step 2
Enclose the entire citation in parentheses.
For example, write (Smith Dep. 19.)
Step 3
Place your citation directly after the sentence it supports.
For example, write "Mr. Smith clearly states that the attack took place between 9:15 and 9:30 that same night (Smith Dep. 19.)."
