An adopted child includes any person legally adopted as the child of another in a court proceeding. Adopted child can be a minor or an adult. State law determines whether an individual is a proper candidate for adoption. By adoption a relation is created between two persons who are not naturally related. The adoptive child is given all rights, privileges, and duties of a child in adopted family. The adopted child is considered as the legal heir of the adopted family. An adoption will not be prevented by the fact that a child has a legal guardian. Usually the purpose of adult adoption is to facilitate a device for inheritance.
In the U.S. all adoption procedures are regulated by statute. There are state specific statutes that prescribe the rights and responsibilities of all parties involved, the conditions, manner, means,and consequences of adoption.
