the site is down, so I can't get details..
how old is said "child"?
If she is still college aged, and actually DID drop out to help her father's campaign, then I would think that short of some catasthropic event, her parents would be happy to fund her education and get her out of the house. Or help her find her way.
From the article:
I don't think dad has any legal obligation to provide her with shelter, financial support or even conversation. However, the father-daughter relationship cannot be dissolved - she will always be his daughter and he her only father. So, I guess the question is not what must he do, but instead what should he do, under the circumstances.
