At the moment my husband and myself just recieve benefits so obviously our outgoings are going to be very basic as we have very little coming in. If hubby gets a jobs in the next year will the or let us increase our expenses for stuff like food and clothes so we can have a decent amount or will they say that you managed on that amount before so the extra will have to go into an IPA? If i put down now how much we would actually spend if hubby was working it puts our disposable income way into the minus figures.
You should put down your I&E for your current situation. If you income changes in the future then a new I&E will need to be completed and you can then put updated clothes, etc. figures.
