Hi and welcome and congratulations on the impending new arrival.
It would depend on how much you owe and what disposable income you would have as to whether or not an IVA would be suitable for you, and you need to take professional advice. Visit
www.iva.com for a list of companies, or you could contact Melanie Giles who posts on here, and whose details can be found under the experts link on the left hand side of the page.
She is ex-forces herself, and has a lot of forces personnel on her books. She would be able to advise you.
However, if some of the debt is in your partners name, or is joint, then she will need to take out an IVA in her own name. You wouldn't be able to take on all the debt.
