I'm not expert either but, making the obvious assumption that there would naturally be communications prior to any bankrupcy decision, here's a hypothetical scenario:
Borrower: Hi I can't pay back the £10,000 I loaned from you, would you take a cheque for £5.34 and half a tube of toothpaste?
Lender: No, I'll have the £10,000 - thanks all the same.
Borrower: Well, here's the thing. It's the £5.34 and the toothpaste - or nothing.
Lender: I'll see you in court.
At this point the borrower will either get, or direct an existing solicitor involved.
I fully agree with Jock though, and given your thumbs up, assume you are playing devil's advocate.
