WHEN TO REGISTER AN ORDER OUT OF STATE
When a California child custody order is registered in another state pursuant to the Uniform Child Custody Jurisdiction Act (UCCJA) or the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), the child custody order can be enforced in that state. If you fear your child will be taken to another state, even for visitation, you should register your order.

When a parent moves to a different state you should register the existing order in the State/County that the child is located. The order should be registered with the clerk of the court located in the new county where the parent lives. Registering the order will notify the state/county that there are existing custody orders in another jurisdiction. This prevents the other party from filing new orders through that state/county. The registered custody orders also make the orders easier to enforce should problems arise regarding custody and visitation issues.
