An Idaho Defendants Written Plea (Criminal) is a document that a defendant in Idaho submits to the court to formally enter a plea of guilty or not guilty. This plea is written and must be signed by the defendant. There are two types of Idaho Defendants Written Plea (Criminal): a guilty plea and a not guilty plea. A guilty plea admits that the defendant is guilty of the criminal charge and waives his or her right to a trial. A not guilty plea denies the charges against the defendant and states that the defendant wishes to pursue a trial. In either case, the plea must be accompanied by an affidavit signed by the defendant attesting to its accuracy.
