Eldest DC turns 18 next year. Not sure yet whether they will be going to uni or doing an apprenticeship, but either way they will continue to need financial support for a few more years. Exh has reliably paid CM but refuses to have any contact with me other than via text re contact arrangements, so I can't have a sensible conversation with him about it. What is reasonable to expect from the non resident parent in financial terms once DC are 18?
