Legal Question in Family Law in Virginia

I would advise your best strategy in this situation would be to arrange for a consultation with a Virginia attorney who handles domestic relations matters and who after evaluating the pertinent issues and facts involved with this matter, should be able to advise you accordingly,

Your first step is to advise the father of your intended move; that's usually required by the Court if the custody matter has been in court. He would then have a chance to respond and the two of you can discuss what might be in the best interest of the child. She may also have a preference, which should at least be considered.
