Child support order states parents are to split medical bills 50%. Mother has custody. She took child to two out of network providers when in network providers are available in her area and is asking for me to pay 50% of cost when I was not informed of this prior to child receiving services. 1 visit is to a chiropractor and the other is a vision exam. I have Medical, Vision and Dental coverage on my child. If she would have went to a in network chiropractor cost would be 15.00 copay instead of 230.00 total charges. Vision copay for exam is 20.00 total cost of exam she had at out of network office is 180.00. Am I required to pay 50% of these bills when she didn't verify before taking the child to these places if they were in or out of network and she didn't inform me until after the fact?
