Thank you for your response.
Please do accept my apologies for my delay in responding to you.
I am sorry to hear that your son feels this way about his father. In a ideal world your should feel comfortable in spending good quality time with both you and his father.
Your ex can make an application to court for a Child Arrangements Order but in reality he might not achieve vey much by doing so.
Courts do want to promote a good relationship with both parents and the courts would expect you to promote the relationship between father and son.
If your ex did make an application to court, then the court would likely ask a Court Childrens and Families Officer (Cafcass) to speak with your son and ascertain his wishes and feelings. Given your sons age and your comments about him being an intelligent young man then the court is likely to give high regard to you sons wishes and feelings.
I rather suspect that the outcome of any children act application by the father would be a 'reasonable contact order'. That being that contact isn't defined but rather the 'door left open' for a relationship to be built up in the future should your son so desire the same. The court would expect you to promote that relationship and it would be helpful if you explain to the court that you are not opposed to such contact and that you have tried to encouarge the same by speaking to your son. There is also the issue of your son's schooling and that you, yourself, are only actually getting limited time with your son, which makes me more of the opinion that a reasonable contact order would be the way that the court would deal with this case.
In any event, before the father could make an application to court, he would have to refer the matter to mediation. If he did not do so the court would reject the application. Mediation is quite a good way fo trying to resolve the issue and some specially trained mediators would also be able to involve your son in the process. You could also consider referring to mediation yourself as a means of seeking resolution.
Let me know if I can help you further.
