(b) Forged signature. The cheque is genuine, but the signature is not that of the account holder. (c) Fraudulently altered. In this case a genuine cheque has been made out by the genuine customer but it has been altered by a fraudster, typically by altering the recipient’s name or by adding words and/or digits in order to inflate the amount. In England and Wales, section 64 of the Bills of Exchange Act of 1882 provides that where a bill or an acceptance is materially altered without the assent of all parties liable on the bill, the bill is made void except when used against a party who has himself made, authorised or assented to the alteration, and subsequent endorsers. Other cases include that of Frank Abagnale, where the perpetrator passes or attempts to pass a cheque that has been manufactured by him/herself, but which represents a non-existent account. Cheque washing involves the theft of a cheque in transit between the writer and recipient, followed by the use of chemicals to remove the ink representing all parts other than the signature. The perpetrator then fills in the blanks to his or her advantage. Sometimes the cheque fraud comes from an employee of the bank itself, as was the case with Suzette A. Brock, who was convicted of theft for writing five corporate cheques to her own birth name from her desk as a loan servicing agent for Banner Bank of Walla Walla, WA. The most notorious "bad cheque artist" of the 20th century, Frank Abagnale, devised a scheme to put incorrect MICR numbers at the bottom of the cheque he wrote, so that they would be routed to the incorrect Federal Reserve Bank for clearing. This allowed him to work longer in one area before his criminal activity was detected. In the movie, Catch Me if You Can, which outlines Abagnale's crime spree, it shows Abagnale soaking plastic Pan Am airplanes in his bathtub and removing the Pan Am insignia on the toys. He would then place the decals on the bad cheques he was writing while pretending to be a Pan Am pilot. From his schemes, Abagnale amassed over $2.5 million. In most jurisdictions, passing a cheque for an amount of money the writer knows is not in the account at the time of negotiation (or available for overdraft protection) is usually considered a violation of criminal law. However, the general practice followed by banks has been to refrain from prosecuting cheque writers if the cheque reaches the bank after sufficient funds have been deposited, thereby allowing it to clear.
