Never sign anything. Some creditors will copy your signature on an agreement. Always digitally sign letters using your favourite font from your office package. My favourite is when they call you at home on your own phone which is for your private use as you see fit and ask you to confirm your identity - brilliant!

When you say you lost your business, were you registered sole trader, limited liability etc? Clydesdale will need to seek an enforcement order before they can " enforce" any action through the court. Is this your sole debt or is your partner liable for any of it?

What kind of debt is it? I.e. Credit card, store card, loan. Did you take it out pre April 2007? If it was disputed how did they get the decree - did you not defend it? Do you have any other debts you are struggling to pay? Sorry for all the questions, but will help me to give you my opinion.

Cancel the card - don't take any chances. If they charge a fee for your DMP, find someone else who will do it for FREE - that way your debt will be cleared quicker as all your surplus cash goes to your debts. Speak to PayPlan or CCCS or, even better, manage your own DMP with the help of the CAG!

Legally, they shouldn't be able to enforce the debt - without a court order at least (see Patel v HFO). But as dx says, creditors are now wiser that the courts are ruling in their favour - so much for the Consumer Credit Act protecting the Consumer! What I am trying to say is, if you can reasonably afford to pay the catalogue off at an amount affordable to you, then I would go down that route - unless you want to end up in Court. I have successfully "written off" unenforceable debts and it is stressful and hard work. Speak to your local CAB about getting onto a DAS. Interest and Charges are frozen and your Creditors are prevented from taking court action against you so long as you stick to the agreement of what you can reasonably afford. Only use the "Unenforceability" route as a last resort.
