Hi, I wanted a bit of advice on benefits. I have been claiming working tax credits for the last few years as a joint claim with my husband. I have recently told him that I want to separate and a few days ago he moved in temporarily with a friend, he has said he is only prepared to stay there a short while and if I am certain this is permanent after 2 months then we will have to sell our jointly owned house (kids and I are still in the house). I need to ring HMRC to update my claim from a joint one to a single one. My worry is that I will have problems as my husband won't have changed his address with work, doctors, other agencies as he is only prepared to stay with his friend for a month or two and he still jointly owns our home so is legally allowed to have his post sent here, use the address etc. We also have a joint account that all our bills currently are paid from. Does this mean I can't claim benefits as a single claim? I'm really worried as if I can't I won't be able to cover the bills and pay the mortgage (he is going to pay child support plus a small amount extra towards the mortgage to me each month). It has taken me such a long time to get to this point and now I am really worried I'll end up having to go back to the way things were as I won't be able to claim any help until I find my feet.
