My 16 yr old son wants to live with nat. father in NJ

Its messy.... not a bad thing but just messy.

My son is 16. He was legally adopted by my husband in 2002. His nat. dad wasn't in the picture by his own choice and inability to help raise him so he just backed off.

Now here we are years later and my son wanted to meet his nat. dad. My husband and I, although hurt, we found his dad and put our son on a plane from NC to NJ. We knew there was a chance he might want to be there longer and with school starting I told him he would have to commit to one year of school to stay. He agreed to see how it went and then make a decision. Well it seems he is staying. He grew up in NJ and has a lot of ties to it. I am ok with the choice... there is a lot he wanted to do after High School in NJ with respect to the Coast Guard and such so its good he is close to the bases.

Now I am in NC and he is in NJ. His nat. dad is willing to pay 100% of everything for him. He has to enroll him in school but has no "legal guardianship" over my son. What do I do and how do I do this? My son's last name is different than his nat. father and although I have the adoption paperwork to show the change.. his last name was never the same as his nat. father's ... I had it as my last name since we weren't married and had no potential.

His nat. dad will pay court fees if needed.. but where do we start? Does he have to start the ball rolling or do I? Again.. I am in NC and they are in NJ.

Any help... please.
