In a Georgia car accident claim, subpoenas are available after suit has been filed. There are two general types of subpoenas:  Witness subpoenas and evidence subpoenas.  Witness subpoenas may be used to require a person to appear for a deposition or as a trial witness.  Evidence subpoenas are used to obtain documents or physical items as evidence in a case.  Very often, subpoenas are used to compel the testimony of police officers or to obtain documents from third-parties or companies who are not named Plaintiffs or Defendants in the case. In a car accident litigation this can mean GPS data, repair and maintenance records, prior claims information and a variety of other evidence relevant to the automobile accident.
