If your wife is charging you for half of the medical bill and then secreting back an insurance payment, in order to obtain a greater benefit, that would be a fraud, and you could sue her for it and obtain restitution of the amounts owed you, plus punitive damages to encourage her not to repeat this behavior in the future.

There may be, but I don't know IL law on this issue. In the absence of an IL statute or a
court order about timeliness of payments, a reasonable time would be appropriate, but reasonable could be a very long time -- perhaps as much as the IL statute of limitations on a contract suit, which could be from 4-6 years.
>3. If my Ex-Wife’s husband adds the kids to his insurance,

No, but as I said, if she's double dipping and you can prove it, then that's a fraud, and you can sue her.
Well, you could send a letter to the doctor, asking him to give you a breakdown of the payment history for your child, including any insurance payments received by him/her. Then just add it all up and see if you've paid one half or not.
If the doctor resists showing you a full payment history, then you can politely inform him that if you later discover that your wife is committing a fraud on you, that you will join him in the action as an agent of your wife, unless he discloses the billing history.
I would not use this little threat until after the doctor refuses to cooperate. If you threaten first, you will just cause the MD to shut down all communication.
