How do I serve subpoenas for a deposition for documents in another state when the case is pending here?

Answer: 
Attorneys who are practicing before this court are empowered by Rule 45 of the Federal Rules of Civil Procedure to issue subpoenas for depositions or documents in any other federal court district. The standard subpoena form should be used. The attorney will complete the heading, indicating the District Court and Division in which the subpoena is to be served. The NH case number is used. The attorney will serve the necessary notices when issuing the subpoena. When the return of service is made, the attorney holds the return. It is not filed in the NH case file. If further proceedings, such as a notice of appeal or motion to quash become necessary, the attorney must open a miscellaneous case in the other district in order to litigate the validity of the subpoena.
