Apostolic exarch is usually a consecrated bishop of a titular see to whom the Pope, as Bishop of the Roman See of the "Apostle" Peter, has entrusted the pastoral care of the faithful of an autonomous Eastern Catholic particular Church "sui iuris" in an area, not raised to the rank of eparchy (diocese), that is situated outside the home territory of an Eastern Catholic Church. The office of "apostolic exarch" thus corresponds to what in the Latin Church is called an Apostolic vicar. Apostolic exarchates are generally exempt (immediately subject to the Holy See), with limited oversight by the Patriarch, Major Archbishop or Metropolitan in chief of the particular Eastern Church. It there is no metropolitan in a particular Eastern Catholic church, apostolic exarchates in their territories are directly subjected to Rome. For example, Byzantine Catholic Apostolic Exarchate of Serbia belongs to the Byzantine Catholic Church of Croatia and Serbia, but since there is no metropolitan in that church, Apostolic Exarch of Serbia is directly subjected to the Holy See.
