DD will likely be going to university this year. I earn a fair salary but DH's salary is such that it would mean that it takes us out of the likely bracket for any financial support for when she is studying. My ex and his wife earn much less and would certainly qualify. I want to ask him to allow Dd to use his address on grant applications . She has a bedroom at both addresses and spends time at both. I fully intend to pay what I can but don't think it's fair to expect Dh to support her . Ex has low income but is financially secure but is also tight as a ducks bum. I know he will pay some towards her costs but we both have sc and other expenses. I don't want to discuss with either ex or dh until I have thought it through.
