As I am sure you can understand, these cases can be very complicated and it is difficult to give a very satisfying answer. Your son certainly has the right to go to court and ask for a transfer of custody - unless, that is, the court ordered a trmination of his parental rights. In the latter case, his only recourse is to ask the court to re-open the case based on some extenuating circumstance. But if he sill has parental rights, he would have to prove that some big change happened to justify reconsidering the custody decision.
With so much at stake, it may be worthwhile for you to consult an attorney and evaluate your options. Although I do not generally take domestic cases, I will in the right situation. If you would like to schedule a consultation, please contact my office.
