Hello, hope this helps you out i just stated a few things i know about adoption, let me know if you need any more detail and information. :P
So basically, <u>Adoption is a process where a person assumes the parenting of another, usually a child, sometimes can be a teen, from that person's biological or legal parent or parents</u>, and, in so doing, <u>permanently transfers all rights and responsibilities, along with filiation, from the biological parent or parents. </u>Unlike guardianship or other systems designed for the care of the young, adoption is intended to effect a permanent change in status.
Hope i have helped you out a little, pm me if you need any more details or information.
