My question is regarding amending current child custody orders. My husband and I physically have his kids with us 5 days out of seven in a given week (all year). However, on paper, their mom is supposed to have them during the school year and my husband is supposed to have them only two weeknights and the 3 weekends out of a month and the summer. I have been documenting the "real" visitation that has been taking place for over 3 years now. The kids' mom has been verbally and physically abusive to her oldest child on many occasions and we feel that perhaps her actions are now affecting the child's physical state (as she gets stomach pains quite often and is constantly ill). What are our chances of winning the case if we were to go back to court and try for full custody? And also, in California, what's the legal age a child needs to be when she/he can request to live with a specific parent? Will a journal and testimony of the child suffice as evidence of visitation and abuse? And lastly, how do you change the jurisdiction of a case from one county to the next if the original case was opened somewhere else? Thank you.
