Legal Question in Civil Litigation in Virginia

FOIA only covers government records, not private information. The only way you can get someone else's private medical records without her permission (assuming she is not your minor child, your conservatee, etc.) would be via discovery in an active lawsuit. She would be able to oppose your request. In order to prevail, you would need to show that your need to use the records in the lawsuit outweighs her interest in keeping them private.
