How long will my grand jury testimony be?
Answer provided by Phillip C. Zane.
The amount of time involved in a grad jury testimony varies and there is no general rule. Sometimes your attorney can get a sense of how long your testimony will need to be based on your connection to the investigation. In rare cases, you can appear only to be told that you will not be able to testify that day in which case your appearance will be rescheduled. It also is possible that your testimony will not be complete after one appearance, requiring a second appearance.
