Hi rcs and welcome to the forum
You are not party to your husband's IVA, but presumably own a half-share of the equity in the property. As there is a restriction over the property, which presumably you agreed to this at the time of his IVA, you are no doubt aware that your husband had responsibilities to his creditors to raise equity from the property in order to successfully conclude his IVA. He will need to think carefully about the implications of this provision, if he is going to move out of the property.
Also, if he is unable to fund his ongoing IVA contributions, then his is most likely to be made bankrupt by his Supervisor which will force you to offer to acquire his half share or see the property sold. Is there any equity in the property at the moment?
As you are in the process of separating, you should seek specialist matrimonial advice with regard to your personal position as soon as possible.
