If you can't pay it, then dont. work out your diposable income each month, and just pay the loan people what you can afford to pay. No matter how small, if you are making the effort there aint a lot they can do about it. A few threatening letters - which all mean nothing - and if you do go to court, all they will say is that you pay something daft like £1 per month. But very rarely will it go to court - as long as you dont ignore it and you make them an offer. It's not illeagal, the worst that can happen is you will get bad credit.
