Hi lawbel and welcome to the forum.
Your husband wouldn't have been recommended as he doesn't appear to have enough debt on his own. However, if you decide to do an IVA on your own, your husband would be chased for the whole of the joint debt, not just half of it.
I recommend that you speak to one or two more IP's. There are several who post on here who come recommended.
Visit either
www.iva.com where you will find reviews of companies, or visit the expert link on the left hand side of the page where you will find contact details.
Robbie, I recommend that you do the same. However, if you want a clean start then I think bankruptcy could be the way forward for you.
Speak to a professional though before making any decisions.
