Capitalize District Attorney as Political Entity, Not as One of Many
Capitalization
Rulebase Summary
Capitalize 'district attorney' when it refers to the political entity that the office represents — i.e., the one elected official within a jurisdiction. Do not capitalize when it refers to a local office or one of the many deputy district attorneys who try cases. Capitalize 'District Attorney's Office' only when it represents the entity itself, not a specific local office.
Examples
A. This will be taken up by the district attorney's office of Los Angeles.
A. This will be taken up by the District Attorney's Office of Los Angeles.
Refers to the political entity — capitalize.
A. We will meet in the District Attorney's office at 10:00.
A. We will meet in the district attorney's office at 10:00.
Refers to a local office, not the entity — lowercase.
Transcript Notes
There is just one district attorney within a jurisdiction — the elected official. All others trying cases are technically deputies. Since there is only one, the form is singular possessive when referring to the office itself. Capitalize only when referring to that single elected official.
