I'll keep personal details a little vague so as not to be outing.
Close family member has a daughter, who is married with a 5yo. She split with her husband towards the end of last year. She moved out into a council flat, and altho he said she could take anything she wanted out of the house they own, she won't be getting any money out of it (they're both on the mortgage, bought the house 7 years ago). I think this is so wrong 
Despite him always slating Dads he knows not paying anything in maintenance, he is now refusing on the grounds that the Mum works full time?! And he has the child EOW and takes her to school a few mornings a week.
AIBU to think he's wrong and a massive hypocrite? The family member/Mum doesn't want to rock the boat so is going along with it, and is refusing to consult a solicitor for advice.
She's also always saying she has no money (she's in a fairly low paid admin job, doesn't have a career as such...unlike him!).
