You can have another IVA - why do you need one? I doubt you can have two going at the same time.
Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

You can have an IVA after having had one in the past. You cannot have two at the same time. Indeed, this would be impossible, as ALL unsecured debt has to be declared and included in an IVA, so there would be no debt to be in the 2nd IVA. Any new debt incurred during the IVA will mean that the arrangement could fail.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
