As far as what you have described, you have provided the mother with all necessary health insurance information when you provided her with the insurance card. You are not obligated to give her specific details about your plan, merely cooperate with the coverage so your daughter gets treatment.
Until she can be more specific with how you are not following a specific court order in your Judgment, and I would ignore her. It sounds like you are doing everything correctly.
To be certain that you are following every order, you should consult with your local Family Law Specialist who can review your actual orders and give you the best advice possible.
I agree with Ms. Fountain. Additionally, the law requires her to reimburse you for one-half of medical expenses. Take your daughter to the dentist, pay for it, and then within 30 days send her a bill showing the expense that you paid and request that she reimburse you. She will have 30 days within which to do so. If she doesn't, you can take her to court for reimbursement.
I can be reached at 714-442-1522 if you have further questions. Before accepting any answer as a final answer, you should have your case reviewed by an attorney. No attorney on Avvo has read your paperwork and therefore cannot give a completely valid answer suited to your case.
