I voluntarily added my children to my health insurance by asking the judge for a court order allowing me to do so, however, my ex did not want me to have my kids info (to prevent me from filing for them on my taxes) so she refused to cooperate with the order. HFS sent me their socials to add them to my insurance, which I did, and I sent my ex the insurance cards and information. Now, my ex is refusing to use my insurance for the kids and has been using Medicaid as the primary source of insurance without telling their doctor's office that they also have private insurance from my job. Can she get in trouble for this if I report her to HFS for fraud? What can happen once HFS realizes she has intentionally left my insurance off in an effort to avoid the co-pay?I also believe she is intentionally keeping my insurance off in an effort to prevent me from seeing when they go to the doctor and what doctor they go to. We are currently in the middle of a custody battle, to which a GAL has been appointed, but she refuses to cooperate with the investigation as well.
