I have a 16 yr old son and a 13 yr old son that live with their mother. My oldest son has wanted to come live with me since he was 10. For the past 4 years his mother has gone back and forth about it. He now is 16 and is adament about coming to live with me. If his mother willingly lets him come and live with me how do I go about changing the child support order that is instated and do I have to go to court to change his residence.
