Fraud is a broad charge that can cover a wide range of alleged crimes.
The main piece of fraud is that it involves:
For example, you might defraud your bank to get a loan by lying about your income or fabricating your timesheets.
You might lie to a potential employer on your CV in order to get a well paid job.
If you get a benefit of some kind, for yourself or others, by lying about something then there is a chance that you could be charged with fraud.
The penalty for fraud is a maximum of 10 years in prison.
