If you think your creditfile is already damaged might be worth getting a credit report to check this.
If that is the case go for a short settlement, moral hazard? serously.
What are the banks doing right now with their creditors? They are writing down the value of their bonds, short settling if you will. No one talks about that in terms of moral hazzard.
MBNA and many other banks have charged penal interest rates for years and have also been guilty and fined for over charging customers in the past.
You are within your rights to try and get the best deal for yourself, use your head don't charge in and tell them you have €13k in your hand, your position should be that you may be able to raise (funds) IF a suitable short settlement could be negotiated......
