My sister (currently living in CA) is facing severe mental harrasment from her in laws. Previously they (in laws) used to be in another country. So that time it was somewhat manageable to her. But since they move to US on 2007, she is going through a very bad time as her in laws always tries to put her into false position and use her husband to scold her. It seems to us that if they stay with my sister than she might end up as a psychiatric patient soon as she can not protest to someone's wrong behavior.
Can you please advise what she can do in this situation based on US Civil Domestic Violence laws in US (CA). She is not interested for a divorce as she has got two childs. But also she is finding it extremely difficult to stay together with her in-laws. And the problem is that her husband always take side of his parents whenever there is an issue without judgement.
additional info: My sister is a US citizen but her in laws are currently green card holder/US permanent residents.
