In a family where a step-father has raised children to the age of majority, the children, now adults, may desire to formally recognize the parent/child relationship with their step-father by completing an adult adoption. The formal adoption proceeding is a very joyous occasion which formalizes a relationship that, in many cases, has existed for many years.
It is not necessary for the adult adoptee to give notice to his or her birthparents. It is also not necessary to terminate the parental rights of the adult adoptee's birthparents. Some adult adoptees choose to inform their birthparents of the legal relationship established with their step-parent, but such notice is voluntary. In the State of Idaho, the adult adoptee may be adopted by an Idaho resident. The prospective adoptive parent must show the existence of a parent/child relationship for more than one year while the adult adoptee was a minor or, if less than one year, show through an investigation that a substantial family relationship has been created.
