Hi jacqui and welcome to the forum
I assume that you mean creditors are pursuing you rather than debtors?
Were you jointly liable for these debts? If so then they are also your responsibility - I do not understand the advice you were given about entering his IVA as a contingent creditor. That does not seem to make sense!
With regard to the property - is this jointly owned? And does your husband's IVA provide for him to raise equity from the property during the fourth or final years? If so, then you will need to give your permission to this, and this should have been sought before he entered into his IVA and not after.
Get him to show you the IVA documents and read through them to see what he has actually agreed to.
