Hi, i hopw someone can help me. My childrens dad has recently lost his home (we are not in a relationship) and he is struggling to find somewhere else to live (housing crisis in our area) we have 3 children together 2 severely disabled and in receipt of dla. He works full time and he has asked if he can stay with us for a few months while he finds some where new to live. My question is how would this effect my universal credit? He has said he'll help towards rent and pay his usual child maintenance but I'm scared it will dramatically reduce my own universal credit? I also dunno how it works and how to inform UC of this change as he isn't a partner? Or is this not allowed?
