The links are great, but if you don't have joint legal, it's a moot point. So if you have joint legal and you have made repeated requests for this information (and it is stipulated in your CO that the CP provide it to you) and the CP still refuses to give it to you, you can file for contempt on that. But you need to have documentation to back it up, which is why you need to have the requests and denials in writing.
If you do have joint legal and make contact with the doctors or schools, always make sure to take a copy of your order with you to prove you have joint legal. If you request info from the school, also reqest a copy of the emergency info card. If you have joint legal, your name should be on there as well.
Oftentimes CP's who refuse child's info to the NCP also eliminate emergency info on that parent to the schools. No, having your name on the emerg. info card doesn't automatically mean you can pick up the child from the school, but it is another source for the school if something were to happen to the child and the staff cannot get in touch with the CP. We had this happen with SS..........they couldn't reach BM, DH works out of town all week, so I was the 'next person in line' on the emergency card.
