who is the legal guardian of a minor child
Legal guardian A legal guardian is a person who has the legal authority (and the corresponding duty) to care for the personal and property interests of another person, called a ward. Guardians are typically used in three situations: guardianship for an incapacitated senior (due to old age or infirmity), guardianship for a minor, and guardianship for developmentally disabled adults.
Adult adoption Depending on the laws of the jurisdiction, adult adoption may not be available as a legal option. In the United Kingdom, only children may be adopted. The Adoption and Children Act (2002) states, "An application for an adoption order may only be made if the person to be adopted has not attained the age of 18 years on the date of the application."[6]
