Thanks to Mark S. Sullivan, a retired Army Reserve JAG colonel, for instructions in how to obtain witnesses and documents from the Department of the Navy. Mr. Sullivan recently posted to the American Bar Association Family Law Listserv complete instructions regarding the production of Department of the Navy witnesses and documents for the purpose of litigation. Mr. Sullivan says: "I suggest that you review carefully, but it appears to me that the request needs to go to the General Counsel of the Navy. See enclosure 3 page 4. There's an address and phone # listed.
Mark S. Sullivan practices family law in Raleigh, NC and is the author of THE MILITARY DIVORCE HANDBOOK (Am. Bar Assn., 2nd Ed. 2011)
Note also that all of the questions at enclosure 4 need to be answered.
subpoena in and of itself, isn't good enough.
