Hi Jock! Love the name.
You have several options available to you, one of which is an IVA. You should really sit down with your girlfriend and work out a statement of your joint finances as you are now living together. Congratulations on the baby by the way.
It sounds to me as if there will not be much money left in the household budget when she gives up work, but you do really need to sit and work out what your finances are likely to be post June.
I have a form you could use as a template on my website, which you may find useful. Treat your debts as joint debts for now, and try and work out if there will be anything left to offer to creditors once that bundle of joy arrives in June. If not, then as you live in rented accomodation, bankruptcy proceedings may be the best option to give you a proper financial start as a family.
Keep posting if there is anything else we can help with.
Regards, Melanie Giles, Insolvency Practitioner for over 20 years.
