Fraud is a crime; a general definition might be "deliberate deception to secure unfair or unlawful gain", but in simple terms it's lying. If you lie to someone for financial gain, it's a crime. But violating the terms of a contract is not a crime, at least in the general case.

Because that's what the law says. :)

Very, very simply: If you lied, it's fraud. If you didn't lie, then it's not fraud. It might well be some other crime, but it's not fraud, because fraud is a word that means lying. So you say:

> went against the terms of the contract in order to deceive

But it depends what you mean by that. If I meant to follow the contract when I sign it, but later change my mind, and you just assume I'm following it, you are deceived, but I didn't lie, and it's not fraud. If I didn't mean to follow it when I signed it then I'm lying and it's fraud. Similarly if I mean to follow it when I sign, later change my mind, and you then ask me "hey, are you following the contract?", and I say "yes" even though I'm not, then I'm lying, and it's fraud. The key element isn't whether or not you were deceived, or whether or not I actually followed the contract, but whether I lied, because that's what the crime is.
