My ex father in law added my children on his insurance policy when he had temporary custody of my children and I had insurance on my children at the time he added them under his policy. Is this insurance fraud? Now my ex wife and I have joint custody and the grandparent still has my children on his insurance and my ex is using the insurance I have on the children as secondary and her stepfather's as primary. Is this insurance fraud? What I can do about it?
Thanks a lot
