Subpoenas are documents issued by a court that compel a person to produce records, to give testimony or to otherwise participate in legal proceedings. Literally meaning under penalty, ignoring a subpoena results in legal consequences. If you need to have a subpoena issued to another state because there is information that's of value in that state, you need to know the proper rules and procedures to follow to get that subpoena.
Contact the court in the city, county, parish or state court where the individual for whom you need a subpoena lives. You need to speak to the court administrator of that court and inform that person that you need a subpoena for a case in your state delivered to a person under that court's jurisdiction.
Fill out the appropriate subpoena forms. You can go to the court in question in person, or you can have the forms mailed or faxed to you so that you can fill them out. You're going to need the court file number, name of parties in the case, information of person requesting the subpoena, purpose of the subpoena, name of assigned judge, number of subpoenas and the necessary subpoena fee that the court charges.
Return the completed subpoena forms along with the payment. The forms may be sent by fax, but the court may also allow you to email them. Discuss the rules of that particular court with the court administrator as to how the documents need to be returned, and what form the payment needs to take.
