Legal Question in Family Law in California

Yes, all states enforce child custody judgments and orders of other states. There is a nationwide law called the Uniform Child Custody Jurisdiction and Enforcement Act that, among other things, has provisions for enforcing one state's rulings in another state. The only problem is the trouble and expense you have to go to, since you have to submit your orders to the local courts in the other state, have them turned into orders of that court and then get the authorities to enforce them.
