If you were served with a summons and complaint concerning a lawsuit against you, there is no date on the paperwork unless the matter is a small claims matter which from what you have written suggests that it is not.If the matter pertains to an auto accident, you need to call your insurance carrier and advise your representative about the lawsuit. You need to tender the defense of the lawsuit to your carrier (fax a copy or e mail it) so that it can defend you.In the interim, you should consult with an attorney who practices in the area of personal injury defense matters about the lawsuit to make sure that you do not have a default judgment entered against you.
