How would one go about adopting a child who does not legally exist?
One of the prospective parents is a trained social worker, would he still require training and/or classes to take care of the child? What about paperwork, because the child has no vital records? He is obviously malnourished and has nothing beyond very basic communication skills, but he can tell people that he's lived in a cave for as long as he can remember. If it matters, according to a doctor's estimation, he's around eight years old.
Basically, I would like to know how this would differ from a more normal adoption of a special needs child. Because it's such a strange and specialized topic, information does not have to be Canada-specific (although obviously that would be preferred) especially if it pertains to the States, as there's no reason I can't move this part of the story a few miles south if need be.
Google search terms tried: Feral child adoption, adopting feral children, feral child adoption by humans, Canada adoption legality, Canada adoption special needs, special needs adoption "socially isolated child", missing birth certificate
as a last resort, turned to Wikipedia articles on feral children and adoption
EDIT: The kid isn't technically a feral child, I was googling that term because it was the most similar term I could find to his particular circumstances. He has only been isolated for between four/five years, but his parentage is unknown. Because his upbringing wasn't quite as damaging as that of an actual feral child, I'm more interested in the concerns of him having no birth certificate.
