This is an alarming new trend. I was recently sent a cheque in the post for compensation due to me for a badly fitted kitchen. It arrived by general post which I found quite alarming (especially as I had been promised a signed for delivery) but of course relieved it reached me.  

Can the criteria to change your name by deed poll be so easy meet? I don't know but sending or receiving large amounts by cheque should always be managed with caution. It's almost like sending cash in a birthday card! We need to make it harder for the fraudsters to get hold of our money.
