Asking for someone else. If your parents are divorced, are your loan/grants calculated on their joint income or the income of the parent you live with? I'm guessing the former but I'm not in this situation so need to check.
Also, if a parent doesn't want to give their details, does this mean you can't apply for income assessed? And if they did give their details do they stay private from the child? (I mean obviously you'd be able to guess based on the calculator thing but I'm talking about the forms...)
