Get him to call the bank and ask for the statement for the relevant month - they should be able to still supply it but they may charge a fee to do so. With that evidence of that and the loan agreement in his name, that should be good enough. Just make sure its made clear the car is his if the OR asks for details. You can contact the insolvency service prior to BR and ask for their advice as well to ensure this will be the case. See
www.insolvency.gov.uk for information on how to contact them.
I have certainly read on other forums that as long as there is evidence the other party paid, then it doesnt matter who is on the car registration documents - as long as the other person is claiming its theirs. The only catch I can see, is if at the same time the car was purchased, you started paying a monthly sum to your partner - the OR might question that! And if it isnt yours, you probably wont be allowed any allowances for it in your I&E (ie petrol, servicing etc).
