Hierarchy of authority parents versus yeshiva

 The question was recently asked

In the yeshiva world who is the final authority - parents or yeshiva? This is an old question

A related issues is father versus mother - can a woman have a Rav telling her to ignore her husband or to divorce him?

Can a woman have minhagim or chumros that differ from her husband?

Can a rosh yeshiva tell a bachur to marry someone that the parents don't think is appropriate

Can children  learn in a seminary or yeshiva that parent's don't like

Can they adopt minhagim that differ from their family?

 Is it different among Chasidim or Sefardim or even Yekke's 

Does modern Orthodox deal with this?.

If parents want children to get job training or go to college - do they have to listen?

If the yeshiva wants involvement in questionable financial aid programs but parents object

can a person be forced to vote for a particular candidate by parents or rabbis
