Advice on My Scenario Pt 12-Less Talk More Action

[OrangeK]

Ok, so question regarding the doctor appointment thing from yesterday.

Here is my plan.

I called today and paid the past due balance She never paid from 2017.
He has an appointment tomorrow morning to get the physical done.

I plan on completing the appointment, getting copies of the paid invoice including the bill for the physical and the payment of the past due balance. Making 3 copies (one for me, one for court, one for WW)
I will put the letter from the school, the paid invoices, and a copy of the complete physical exam form (i wll have copies of all) in S3's folder in his backpack.

I then plan to send the following message.

"When i picked S3 up from school on Tuesday he had the letter from school about needing his physical exam in his bag. I had thought you had planned to take care of that, but i went and got the appointment done today. I also put a copy of the paid invoice in the folder with his letter and a copy of his completed physical exam form.
Please remit payment of 50% of the paid balance of medicals bills to me via check or money order as outlined by the stipulations of the medical section of our divorce papers
Have a good weekend"
