Hi Louise
If your IVA is not accepted, but your partner's is, you will have to decide whether one person carries on leaving the other to consider other options. If your partner could sustain an IVA in their own right, then they could continue, but the reality is that most couples share their incomes and expenditure and rarely have enough individual disposable income to carry on with an IVA in their own right.
With regard to joing loans, you are both still responsible for the whole lot and with property only your half is taken into account in the proceedings you decide upon.
