I have a girlfriend in California whose husband has abandoned her. She is 67 years old. She owns a home that is worth a considerable amount of money that is in her name only. Is she entitled to financial support from her husband under californian law?

Courts set few specific guidelines to attaining this broad goal: instead of telling judges how and when to award alimony, most courts simply grant them broad discretion to decide what is fair in each case."
