I can see the banks point of view otherwise anyone could falsely administer the same scenario to exit an account with debts. I'm not saying she is doing this but the banks have to vigilant. The same thing happened to me many years ago. My ex-wife closed the account taking the available funds just above the overdraft but when her direct debits and OS cheques came through, it left the account in debit. It wasn't settled until my divorce came through 2 years later.
She needs to see a solicitor.
She did mention the possibility of seeing a solicitor, but she hasn't got the money to pay for that. And he won't want to get involved either. He is being proper childish about it all.
I think this is probably the best option to be honest.
Alternatively, does he owe her any money and can she prove this?
If so and it's more than £750, could try threatening to bankrupt him (https://www.gov.uk/apply-to-bankrupt-someone/overview). That way he would be forced to sell the house to pay off the debts.
I will mention this to her as well. Thanks.
