Fraud

In law, fraud is deliberate deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud itself can be a civil wrong (i.e., a fraud victim may sue the fraud perpetrator to avoid the fraud and/or recover monetary compensation), a criminal wrong (i.e., a fraud perpetrator may be prosecuted and imprisoned by governmental authorities) or it may cause no loss of money, property or legal right but still be an element of another civil or criminal wrong. The purpose of fraud may be monetary gain or other benefits, such as obtaining a driver's license or qualifying for a mortgage by way of false statements.

A hoax is a distinct concept that involves deliberate deception without the intention of gain or of materially damaging or depriving a victim.

As a civil wrong

In common law jurisdictions, as a civil wrong, fraud is referred to as a tort. While the precise definitions and requirements of proof vary among jurisdictions, the requisite elements of fraud as a tort generally are the intentional misrepresentation or concealment of an important fact upon which the victim is meant to rely, and in fact does rely, to the harm of the victim. Proving fraud in a court of law is often said to be difficult. That difficulty is found, for instance, in that each and every one of the elements of fraud must be proven, that the elements include proving the states of mind of the perpetrator and the victim, and that some jurisdictions require the victim to prove fraud with so-called clear and convincing evidence.

Advance-fee scam

An advance-fee scam is a type of fraud and one of the most common types of confidence trick. The scam typically involves promising the victim a significant share of a large sum of money, in return for a small up-front payment, which the fraudster requires in order to obtain the large sum. If a victim makes the payment, the fraudster either invents a series of further fees for the victim, or simply disappears.

There are many variations on this type of scam, including 419 scam, Fifo's fraud, Spanish Prisoner scam, the black money scam and the Detroit-Buffalo scam. The scam has been used with fax and traditional mail, and is now prevalent in online communications like emails.

Online versions of the scam originate primarily in the United States, the United Kingdom and Nigeria, with Ivory Coast, Togo, South Africa, the Netherlands, and Spain also having high incidences of such fraud. The scam messages often claim to originate in Nigeria, but usually this is not true. The number "419" refers to the section of the Nigerian Criminal Code dealing with fraud, the charges and penalties for offenders.
