If you were repossessed in 1991, then in accordance with the CML agreement, the debt is statute barred from end 1997 UNLESS you acknowledged that you owed money as a result of the reposession OR your former lender is not CML member.(posted 7881 days ago)One way forward to consider is let them take you to court and when they get a judgment, file for bankruptcy or let them do it for you. It is worth getting the proper facts together on this because you will then be able to establish if they have a case or not (in other words, are they out of time or not)
The MIG covers the lender not you. They can still come after any shortfall subject to the new ruling - see posts further down for details.
You could possibly stall further action by contacting the former lender and telling them you don't have two brass hapennies to rub together and hope they go away - they might if you prove your lack of capital and income - particularly if you are on DSS funds.
