adult adoption n. The adoption of a person over the age of majority (as defined in State law).
Adult adoption was quite a common occurrence during the ancient/classical periods to carry on a dynasty, occupation, or family name; to care for a parent in old age; or to protect property rights.
Today, however, there are three main reasons people pursue the adoption of an adult person.
Changes Effected by Adoption
In the same manner as child adoption, the adoption of an adult will result in changes.
Note: If the only purpose for considering an adult adoption is to change the name of the person to be adopted, name changes are relatively simple procedures and can be done without severing parental rights of existing parents.
Governed by State Law
Adult adoption is handled differently in all states. Some state statutes only provide for adult adoption if the person to be adopted is of diminished capacity. Some states require the consent of the spouse of the person to be adopted (if married), some require notification of biological parent(s), and some require nothing more than the consent of the adult parties.
