So after a week the case worker responded with this.
He has not asked anything else nor did he answer my questions so I am leaving bs on my insurance....he was pissed I switched over to going through the state but I can't work with him nor do I want to spend 2k to have my lawyer try and work with him.
Message: Hello, I referred this question to a Medical Child Support worker. She reveiwed your court order and said that you are ordered to carry the insurance and he is ordered to pay a $xxx/month contribution towards the insurance premium. If he were to place bd10 on his insurance without first changing the Court Order, he would still have to pay the $xxx/month and you would still be required to carry bs10 on your insurance. If you were to take him off your insurance, while still ordered to have him covered, you would then be 100% liable for any unreimbursed/uninsured medical bills. All that is to say, even if dads insurance is more cost effective, he would need to file a motion to change the medical language in your current Order.
