A protected person is a minor or incapacitated person for whom a court has appointed a conservator. It can also be any person for whom a protective order has been made.
In International law, a protected person is one who is in the hands of an occupying force during a conflict. Protected persons are entitled to a standard of treatment by the Geneva Convention Relative to the Protection of Civilian Persons in Time of War (1949).
In English law, protected person is someone who is an inhabitant of a protectorate of the United Kingdom. Even though the person is not a British subject, such a person is given diplomatic protection by the Crown.
