Question:

Why foster kids don't change their into their guardians' last name and get to keep their own name?

i dont get it

Best Answer - Chosen by Asker: Because foster care is considered a temporary situation and the child is usually cared for by unrelated adults. If the foster parents adopt the child legally, the child can have his name changed their last name. Also, sometimes the goal is to put the child back in the home with his birth family, so that would just require another name change.
