Hi Sarah
You ought to be able to phone your IP at any time if you have queries like this - we are there to hand hold you through all of the procedures and provide support in dealing with your creditors.
The IP is correct in saying that they cannot really proceed until they have all the information from you, so make sure that you send them all the documents they have asked for as soon as possible. In the meantime, I suggest that you continue to advise your creditors that you are in the process of proposing an IVA to them. There is no harm in making token payments in the meantime.
This may stop the ongoing barrage of calls and letters, and is unlikely to affect the eventual outcome of the IVA at all.
Regards, Melanie Giles, Insolvency Practitioner for over 20 years.
