I'm currently on tax credits and my partner is moving in with me so I need to go onto UC. I get CB, CTC, WTC housing benefit and council tax benefit at the minute. When he moves in I will lose all but my CTC and CB. My question is does he have to start a claim for UC too if I only want to claim the child related benefits (they're not his kids) He works full time and it would just be a complete faff on him having to go to the "interview" when hes not claiming anything.
Oh also he pays around £300 child maintenance a month, do UC take this into account? Thanks.
