Its called "Emancipation", and generally its with teenage kids who want to be free from their parents. The child would have to prove they are able to support themselves on their own.
If the parent or parents are able to manage themselves perfectly fine without the child being a hindering problem, then the parent or parents have the right to adopt that child (some tests may be given.)
The child should follow which ever he or her chooses to identify themselves :)
