Definitions
A corporate parent is an organisation, like a district council, that acts as a parent for children and young people in care. They are responsible for making sure you are looked after, supported, and given opportunities to reach your potential, just like a parent would. This includes helping with your education, health, and preparing you for life as an adult.
All Rights Exhausted (ARE) means that a person has tried all the legal ways to change a decision, but there are no more options left to appeal. This usually happens in situations like immigration cases, where all chances to stay in the country have been used up and nothing else can be done legally.
