Letter to school Re: Parental Rights

Hi

Does anyone have a letter I can send to the school regarding parental rights

Or is there any links also to what our rights are, or any templates

I've emailed the x wife solicitor, and they haven't replied as of yet. I'll be sending them the same letter too if they don't want to co-operate

Then I'll show the judge too as they're being un co-operative

I'm hoping the school and solicitors will help. The school seemed assitive, they said I need to be added to SIMS system via x wife.

Only thing is x wife and solicitors are not assisting me....it's day 1 they have not replied as I sent the email on Friday and it's Monday now
