I live in Kansas, Not California so I can only Give you what I experienced in Kansas. I was in the same situation, I was in court trying to get custody of my Children. The final Decision was they looked at who was the caregiver, Finances really had nothing to do with it. Since I was the one that worked and made the money to support the Family, She was the one that stayed home and took care of them, She was given Primary Custody. Afterwards she found Numerous Boyfriends, Moved the Children often and was not concerned about their education, I went back and received Custody. More Courts are starting to give Custody rights to Fathers then before. Hope this helps.
