Seems strange to me, it is quite normal to send in bank statements/wage slips at the final review but can't see the need to fill out a fresh income and expenditure form
It is not usual, as it serves no purpose if the IVA is at its natural conclusion. Pay-slips will need to be reviewed to check whether all uplift payments have properly been accounted for.
This happened to me as well. I queried it and was told that it was computer generated and to ignore it. Maybe they should programme their systems correctly!
