A person commits forgery if, with intent to defraud, the person: 1. Falsely makes, completes or alters a written instrument; or 2.ARS § 13-2002 defines Arizona's forgery law. In Arizona, a written instrument may be considered a forged instrument if it has an altered dollar figure or other material information. Forgery is a Class 4 felony in Arizona, which means a conviction can carry significant penalties, including imprisonment and fines. The revised text makes clear that the responsibility for filling in the summons falls on the plaintiff, not the clerk of the court.
