If your father never signed the will (versus knowing he signed the will and all you have is an unsigned copy), then its not a valid will. His estate will pass either by a prior fully executed will or via the law of intestate succession. You should consult with an attorney who can get more facts and tell you how that would all work out. maybe that would be acceptable to all of you and you don't need any extraordinary efforts concerning the will.
