Regardless of the form of custody, it is not legal for one parent to relocate out of NY without either written permission from the other parent or a court order granting relocation.
He will need a court order to relocate with the chilren. If he relocates with the children without a court order you should hire an attorney immediately to bring an application against him in less than 6 months of the relocation.
