I have started to complete the UC migration claim for for my son who is disabled. I think I have made a mistake and want to change it, I can't find any way through the DWP pages to do that, please does anyone know how you can re-visit a page and alter it before submission? Other GOV.UK sites I have to use allow you use them as working documents and to go back and alter things before submission, does UC not allow that? Thanks.
