A system in which a minor has been placed into a ward, group home, or private home of a state-certified caregiver, referred to as a "foster parent" or with a family member approved by the state. The placement of the child is normally arranged through the government or a social service agency. The institution, group home or foster parent is compensated for expenses unless with a family member. It involves the process of adopting such minors legally or fostering them until they reach adulthood.
