To answer this we need to know where the children are living. Divorce and child support are strange in that the jurisdiction of the divorce only requires a parent to live in a state or a county, but that is seperate jurisdiction from jurisdiction over teh children. If the children are staying with you in CA the majority of the time, it is likely that not only do CA courts have jurisdiction over the custody order, but that presumptively the court will want the children to stay in CA.
Let me know if I'm misunderstanding the facts here, but it sounds likely that you could simply file in California and move for custody there.
