Under the laws of all states in this country, a subpoena to attend trial (civil or criminal) must be personally served upon the third party witness. Unless it is served in such a manner, the person desired to attend trial does not have to attend.If you ignore a subpoena to attend trial that was personally served upon you, the result is that you can be held in contempt by the court for ignoring the subpoena to attend trial with possible fine or jail.I would not ignore the subpoena that you were personally served with.Good luck.
