My question involves a child custody case from the State of: New York. I have a son who is 18 years old and has Asperger Syndrome and other medical problems. I have joint custody with the father. I have residential custody. When the child turned 18 the father convinced him to move in with him and is refusing to get the child the medical care he needs. I've been told that because the child is now 18 that there is nothing I can do. Are there any options?
