May a parent with sole custody deny the other parent access to the childs school and medical records?
No, unless the court has issued its Order denying the access. In fact, under Arizona law, a person who does not comply with a parent’s reasonable request for records must reimburse the requesting parent for court costs and attorney fees that parent incurs in forcing compliance with this law. In other words, a non-custodial parent may request a child’s records directly from a school or medical facility, as long as the request is done reasonably.
