support group CB plus IR top up query

hello, another query please . iv recently been put in support group on appeal and have just received my back pay which is great as its really needed. i live with my grown up sons but am getting married at end of month. my partner has his own house at the moment. iv received a form to fill in asking about my sons wages, apparently this is because i receive £15.50 a week IR top up now.will my sons pay be taken into consideration with the back pay iv received and how is it likely to affect future payments. i realise it may stop altogether when im marriec...my partner doesnt work 24 hours but does earn around £6000 self employed thank you s

hello again
please can someone advise me.i was put in support group a couple of months ago and receive an ir top up.i got married 2 weeks ago and phoned dwp to tell them.i explained that im changing my surname but that my now husband will still not be living with me as his business(an old barn which has been converted into group accommodation which he co owns and co runs with his parents)is 75 miles away and he has to be there to manage it.im receiving £15.50 per week ir at the moment.the lady on phone said she'd send me an esa 3 to fill in which needs to be returned by end of month and that I should put a note in to explain the situation.i have made an appointment with a benefit advisor which is tomorrow morning.however on reading the form im wondering if its even worth applying to keep the ir esa part as its so complicated re my husbands work situation.he doesn't work over 24 hours a week and pays himself a small wage of £11,000 per year,but out of this he pays his mum and dads rent of £450 per month as he is living there.this leaves him with only £5600 year to live on but they do have some savings between them which they use to do improvements to the old building plus for holidays etc.
on the form it asks is your partner happy to do this as a joint claim?i don't think he is but it says if not to give as much info about him anyway.this seems intrusive when id just be happy to give the change of circumstances as changing my surname.or am I foolish not to try to claim ir?can I not claim just myself still?im very confused
I honestly don't know what to do for the best.please can you advise before I see the citizens advice tomorrow
as ever thank you for your help
kind regards

just a thought Gordon.we've thought for a while that it might be better to get the accountant to change my husbands pay to not include the £5400 rent and just get it paid to his parents instead as he never sees this money it is paid direct debit to the landlady,so it isn't actually his anyway.with this lower amount of pay of £5600 per year is it likely still to result in my ir being stopped if they decide at any point to treat us as a couple(or if indeed we do buy a house together closer to the business in the future)
thank you again
