Is there a way i can legally adopt a family friends child if I'm 19 and have proof of minor neglect?
There are legal limits to adoption - typically there must be a 15 year age difference. The parents must first be revoked of their parental rights to make a child available for adoption.Also, if you have proof of minor neglect you need to contact the authorities. They will handle the situation.
do you have a job and your own home?
do not adopt your under age girlfriend. ; ) no it would be highly unlikely. A judge probably wouldn't even entertain the notion.
