Hi andrea and welcome to the forum
Was the property included in the IVA in any way - ie equity release during final year? If not then there is no problem in you transferring your interest in the property back to your partner, although you will have to make sure that he pays you for any increase in value you have both enjoyed during those two years.
Secondly, if you feel that you are not going to be able to afford the IVA repayments, you should discuss whether it will be possible to reduce them with your supervisor. He will need to see a revised income and expenditure statement from you, in order to judge whether a variation to the original terms is viable.
