I am in N. C. and have joint custody of my two sons and I am the custodial parent. The ex-husband who lives an hour away has "convinced" my 17 year old son who has Asperger's Syndrome, that he'd be better off living with him and going to another school. My son has struggled in high school due to his disability and neither him nor his father will acknowledge that my son's disability is the reason he's struggled with socialization and understanding the intentions of others, It's the school's fault or someone else's fault. His father has not been supportive regarding the 2015 diagnosis of my son and he has never been involved in any way, shape, or form regarding or even acknowledging to me that my son has a disability. Since my son is adamant about moving, what can I do to ensure that his father continues to take my son to the psychiatrist as directed, take him for therapy, make sure he takes and has his meds filled, ensures the 504 plan is being followed, and ensure he understands the behaviors and how to handle a child with autism rather than his usual domineering, narcissistic ways? He has been both verbally and emotionally abusive to my son in the past and I fear my son will have no emotional support while living with his father. HIs father may tell he will continue to take my son for his medical care but based on his past history, I don't quite believe If I fight to keep my son here, my son will resent me and both he and his father will make life miserable for everyone including my other son . Is there some kind of binding agreement I can have him sign? What if he doesn't sign it? Do I need to modify the custody agreement to include that issue, visitation issue with my younger son who will remain here with me, and put provisions in place in the event this move does not work out? I didn't want to stir the pot but I don't want to mess up either. Any suggestions? Thanks
