Jurisdiction of support is governed by the Uniform Interstate Family Support Act (UIFSA), which is incorporated by most states, including Virginia. The jurisdiction where support will be heard is determined by where the parties and the minor child live.
Jurisdiction over custody matters is governed by the Uniform Child Custody Jurisdiction and Enforcement Act, which is also incorporated in Virginia and relies on the residence of the parents and the minor child to detemine which state has juridiction.
If you have a question as to whether New York still has jurisdiction, you should consult with an attorney.
