Need some SOA help

Hi, I've just been sent my first review for my Trust Deed (Scottish form of an IVA) I've been in it for 14 months and this is the first review we've had!

I need some help filling the expenditure out. Also the income part for myself. I'm a stay at home mum. My partner pays my trust deed on my behalf. The form asks what your income from your job is, what benefits you claim, your self employed income and any other money or assets you have. I was just going to write nil for all of them. I think I should probably put nil for the expenditures too, because how can i have outgoings if I have no income. I was going to fill in all the outgoings on his form instead.

I'd be grateful if someone could look over my SOA and tell me if it looks ok. I don't want to over or under estimate on things too much.

Mobile phone............................ 25
TV Licence.............................. 12
Groceries etc. ......................... 500 (for 6 people. Is this too high? Works out at £115ish a week, which i don't think sounds too hideous. Does anyone know if there are any official government figures for what you should spend per person on food?)

What do you think? There is £200 left over, but if they don't count child benefit as income then that works out even. I'd hate my payments to be increased by £200! For the first time ever I feel like we are doing ok. I have all my budgeted amounts for car repairs etc in envelopes. I've paid cash for all my Christmas presents this year, which feels great!
