Potential Issue

Hi,

I am looking for some advice on the following please.

So in September 23, I went to court to obtain a Child Arrangements Order for my 5 (now 6) year old son, after Mum had been bombarding me with messages asking me to have him full time for around 6 months, also sending some horrible messages about our Son etc. I built an evidence folder and submitted this to the court prior to the hearing, all for nothing as they didn't look at it or take any of it into consideration. 

I agreed to have my son full time, but when it came to changing his school to a school more local to where I live, this is when Mum backtracked and then stopped my Son coming (hence why I went to court and got the CAO).

So now, a few months later, Mum has accepted a HA tenancy 7-10 miles away from her current residence and from my Son's school, she is currently living in a 3 bed house with her partner and her 7 other children (8 including my Son), so she's moving into a bigger property. Which she has not told me herself, I have heard this third hand from two separate sources. Not a problem, I don't particularly care where she lives, although it does obviously affect my pick up times, journey time and fuel expense. 

The other more pressing problem and more concerning issue, is that she is apparently changing the school that my Son and her other children attend so that it is more local to her new residence. Again, this information has been obtained third hand from the same two separate sources.

In the court order, it states that big changes in our Sons circumstances such as changing schools should be discussed and agreed by both parents.

You might be thinking, what is the problem if she changes his school? Well, I do the school run 3 times every week, and my older son (from a different relationship) also attends this school, therefore, it would be impossible for me to get both of them to school on time should they attend different schools.

I have attempted to contact Mum regarding this, she is not replying to my messages (we use a special app to communicate, as agreed in court, so that all communication is recorded). I have also contacted the school to ask if there has been a transfer of school submitted, and they will not give me the information without Mums expression.

When I began to have contact with my Son around 18 months ago, we re-registered the birth certificate, so I am on his birth certificate. I am worried that she may be using an original certificate, without my details on, so that she can manipulate the schools involved to thinking it's only her with parental responsibility.

Mum will contradict herself if she is trying to change the school, as her whole defense during the last court hearing was that I was taking him out of a school that he's doing really well in, and is settled at.

I believe this is quite urgent, due to the skip in her front garden at the moment.

Who else should I contact?

What's my next steps?

Is it a case of going back to court? If so, what do I need to do?

Please feel free to ask any questions, and thank you in advance.
