Foster care is a system in which a minor has been placed into a ward, group home (residential child care community or treatment centre), 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 a "foster 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. Any adult who has spent time in care can be described as a "care leaver", especially in European countries.
The state, via the family court and child protective services agency, stand in loco parentis to the minor, making all legal decisions while the foster parent is responsible for the day-to-day care of the minor.
