Thank you all. They are not claiming at the moment, as despite declaring everything, after 4 months they were told they earn too much and now need to refund £2000. They really don't earn a lot! House is rented. He hasn't moved out yet, but is going to. She is really stressed at going through the whole claim process again. There is no comeback on the Universal Credit Team when they make mistakes. She cannot afford to pay back £2000. It would have been very difficult when they were together, impossible now. We want to make sure he pays towards his daughter, and sees her properly, as she adores her daddy. I am heartbroken for her, and she is so sad. I will get her to contact Citizens Advice. Is there any form of Ombudsman for Universal Credit?
