Thank you dx100uk.
No I have never been asked for my husbands details on any of my forms because my disability benefit is not income related. (It is taxable but the amount I receive is always much less than my personal tax allowance so there is never any tax to pay.)
I fill in a capability for work questionnaire which is directed to myself only, and that's it.
Other benefits are income related such as council tax benefit but I don't claim those as I wouldn't qualify.
Thank you for letting me know about your neighbour, it must have come as a shock to them.
Your neighbour's circumstances might be slightly different to mine, they could be claiming some income related benefits on top, or he/she may not have built up enough National Insurance Contributions prior to making his/her claim for disability benefit.
In those circumstances they do take the household income into account as far as I'm aware, but they do have a habit of changing things.
That is a good point you make about the address, I shouldn't have assumed anything.
I will make sure the DWP fully understand the situation and if I need to do anything different I am sure they will tell me. Thank you for your input, it is much appreciated.
