Check out the simplified newer DRO (debt relief order) I have posted all the acceptance conditions below. These orders are a simplified version of bankruptcy where the debt is under 15k and cost just £90 to start, or free where there is hardship. They last for One year, after that she would be automatically discharged and free from any debt burden, the CAB are authorised to start one if the order is suitable for her needs.
I do wish her all the best, nothing is worth taking such drastic action over ....at the end of the day it's only money and it's a lot worse when they owe it to you !
