Hi babyblue
You certainly look as if you have the makings of an IVA from the brief information you have posted, but entering into such process is a very big step and you must take specialist advice.
The best thing to do to find out exactly how much you owe your creditors, is to ring them up and ask for an "account balance". Make sure that this is the figure they give you, rather than a "settlement figure", as this can often be lower but is only available if you pay off the debt in full, which you are unlikely to do under an IVA.
It is very unlikely that creditors will want your husband to give up his car, as he says it is necessary for travel to and from work. Can I ask how much equity you currently have in your property?
