1. I did not know the person I was living with was a prostitute. Have I committed this offence?
The prosecution must prove that you knew that the person you were living with was a prostitute and that you knew his or her contributions to your living expenses came from what was earned as a prostitute. If in all the circumstances there is a reasonable doubt about whether you knew you were living upon the earnings of prostitution, you will not commit an offence under section 137. In practice if you are living with a working prostitute or are habitually in the company of a working prostitute the prosecution may have a strong case against you for knowingly living on the earnings of prostitution. Even so, depending on the actual circumstances of the case, there may still be a reasonable doubt about your knowledge.
