Hi
You can't I'm afraid
If you move now before an IVA then you will have to surrender some equity in the fourth year.
If you wait until you have an IVA in place before moving you will have to declare your deposit monies and these will have to be paid into your IVA pot.
If the deposit is coming from your partner then you could consider entering into an IVA before you move but you would have to inform your IP of your intention to take out a mortgage and you would also have to inform your mortgage company that you are insolvent.
Why not move now as it will only be your share of the equity that you will have to release and that will be 85% of the house value less outstanding mortgage.
