Idaho Statutes Title 19. Criminal Procedure § 19-1515. Question as to true name of defendant

When the defendant is arraigned he must be informed that if the name by which he is indicted is not his true name, he must then declare his true name, or be proceeded against by the name in the indictment. If he gives no other name the court may proceed accordingly; but if he alleges that another name is his true name, the court must direct an entry thereof in the minutes of the arraignment, and the subsequent proceedings on the indictment may be had against him by that name, referring also to the name by which he is indicted.
