I am sorry, I do not have good news. You can not by law subtract anything from the child support. You will be required to either petition the court for the deduction or speak with your ex and come up with a agreement on the amount. If she agrees to allow you to deduct it then you will want to get this in writing and notarized to protect yourself.
If you choose to petition the courts, you may want to keep in mind that the courts could very well order you to provide this coverage since mom no longer has this coverage available.
Your only other option is to refuse to pay the coverage and ask her to forward the 275.00 to you each month to cover the expense.
I wish you the best,
