Q. When citing to a district court in Florida, how do you show which district the case was heard in?
You are correct, the bluebook is not very instructive for Florida-specific citations. Instead, the Florida Style Manual (http://www.law.fsu.edu/journals/lawreview/downloads/floridastylemanual.pdf) and Florida Rules of Appellate Procedure Rule 9.800 (http://www.floridabar.org/TFB/TFBResources.nsf/0/830A6BC6B90DA05685256B29004BFAC0/$FILE/Appellate%20Rules.pdf?OpenElement) are used to supplement the bluebook.
You definitely need to include the district court in the citation but rather than the way you styled it below, it would look like: In re Guardianship of J.D.S., 864 So. 2d 534 (Fla. 5th DCA 2004).
Also, with respect to statutes, they are cited to the official version of Florida Statutes, with Florida Statutes annotated citations reserved for “court-adopted rules, or references to other nonstatutory materials that do not appear in an official publication.”
Hope that helps.
