The common law did not recognize the adoption of a child. This right is now given by statute in each of the states. A child adopted under modern statutes stands in the same position as a natural child except for such exceptions as may be contained in the statute authorizing such adoption. Laws authorizing the adoption of children are generally held to have no extra-territorial effect. The adoption of a child, under a statute authorizing such adoption, can never have the effect of defeating a vested interest in property.
