Regardless of the type of subpoena you have received, and regardless of the method by which it was delivered, it is important that you engage defense counsel promptly. If you have grounds to object to the subpoena but fail to do so promptly, you could be deemed to have “waived” your opportunity to challenge its method of delivery. In any case, you will need to respond to the subpoena appropriately, and you will need to make sure that you do not inadvertently or unnecessarily disclose information that could increase your risk of facing liability or prosecution.
