You choose an IP who maintains regular contact with you, and who can help to take the ongoing pressure away from you.
The important thing is to be absolutely sure that you can afford to make the repayments being suggested to you. They should feel comfortably affordable - and if in doubt, you probably cannot afford them.
Also make sure that you carefully read through the IVA proposal, and attached terms and conditions, to be absolutely sure you know what you are letting yourselves in for over the next five years. If in doubt, query it with your IP.
Gook luck!
