If you don't already have a court order, you'll need one.
Personal jurisdiction means the court has the power to make that person do something.
A state almost always has personal jurisdiction over someone who lives there. It doesn't matter where the child was actually born. If you don't live in Virginia, consult a local attorney about your state's law. This Act has been passed in every state, and requires each state to cooperate with other states in collecting child support from its own residents. Your court then forwards the petition to the state where the other parent lives, and that state takes action against her.
