Hi robm and welcome to the forum
If you are still a part owner of a property when you propose an IVA to your creditors, then you must disclose your interest.
I think you ought to now sort out your matrimonial affairs - to include a split of the property - before considering an IVA. Solicitors will help you and your come to a decision as to your share of the property - in which you are likely to have retained an interest although it could be argued to be a small one.
Do make sure that your solicitor is made aware of your overall financial position.
