Can you write a quick email (bullet point form bs loads of paragraphs!), with a few on whatever you’ve discussed by phone then your vague plan for the future
ie as we’ve discussed previously, xxxx. You have now requested a written documentation of my plan for dds education so please find below the notes from our discussions to date.
There are 3 key reasons why dd is currently attending x school, which is where I currently am employed in the position of x.
To summarize these 3 reasons:
A. as I have a position at x school we are able to take advantage of the teachers children’s reduced fee, which brings the school fees financially within reach for me
B. Logistics / travel and weekday wrap around childcare needs As I am dds primary caretaker, and look after her on all weekdays it helps that ...,
C. Ethos of the school ... ONLY if you want to get into this and it’s not a horrible issue between you two!!!
If the circumstances change, then we will need to review dds attendance at X school, as the full costs are prohibitively expensive... etc etc etc?
Anyway, something like this? I’d keep it very short though, although refer to previous discussions / the existence of previous discussions where you can.
You need to thread a fine line between reassuring him but also making it clear you don’t have to answer to him as you are co-parenting vs him giving orders from afar whilst you do all the grunt work!
I’d think hard about wording the ‘future’ bit of the Mail, as I’m not sure that you do want to write something that he can hold you to legally, absolving him of any responsibility of paying for his own daughters education. You don’t know how it could be used in the future, or applied to different circumstances.
I’d hold off anything as completely cast iron as ‘ I will not hold you financially responsible for dd’s school fees should this situation arise’, and go for something much vaguer.
