Daughter was recently taken to dentist and her orthodontist recommended she get braces. I informed her mother but she is refusing to pay for half because she doesn't think my daughter needs braces (trying to work this out still, but seems impossible). She is now requesting my daughters health insurance information but I have already provided her with a copy of the medical/dental insurance cards. Am I required to provide anything else besides the health insurance cards? I don't want to fail to provide something I am supposed to. I have joint legal and physical custody. My daughter splits time 50/50 between her mom and me. Additionally I have support order in which I pay my daughters mom.
