Answer
Yes, if you know or suspect the money is criminal property.
Further to the news article referred to below, it is suggested that
you advise the paying party to pay the money directly into court.
The court process protects solicitors from the risk of handling
bail monies. Therefore, there is no reason for you to accept bail
monies into your firm's account.
