Uttering a forged instrument is a criminal offense. When a person knowingly publishes or puts into circulation any forged or altered financial document, legal document or other writing with the intent to misrepresent it as true and defraud others it amounts to uttering a forged instrument. To “utter” means to distribute or offer under the pretense that it is genuine. The uttering of a forged instrument is a separate and distinct offense from the making of it. The accused must not only know that the instrument was forged, but s/he must intend to defraud at the time of offering it.
There are State specific laws on the area. The following is an example of a State law ( Florida) on uttering a forged instrument:
Uttering forged documents is a third degree felony in Florida and may be punishable by up to 5 years in prison and/or a fine of up to $5,000. [Fla. Stat. § 775.082; Fla. Stat. § 775.083]
