It can be confusing and even frightening to be served with a subpoena, especially if you do not know what’s involved. A subpoena is a summons to appear in court. No matter the reason, you need to appear in court on the appointed day and time or else you may be held in contempt of a court order. If you are served with a subpoena, it is important to contact an attorney to sort out the details of your appearance. An attorney also can make sure you are fulfilling all of the requirements of the subpoena beyond your appearance in court, ensuring that you are following the law.
