Legal Question in Family Law in California

Since you don't say whether you were married or not, and you don't say how or under what authority he kicked you out, there is no way to give you any specific advice. If you want your kids, you need to go to court. If you want to move out of state, you have to go to court and get custody resolved first, and a move-away order, unless you want to be at a huge disadvantage when he goes to court. He won't get an automatic abandonment order just because you go to live with family, but his chances of primary custody go way up if you just leave without doing anything first.
