Prerogative Court of the Archbishop of Canterbury
The Court of the Archbishop of Canterbury (PCC) had superior jurisdiction in all of England, Wales, Isle of Man, and the Channel Islands and sole jurisdiction where testators had bona notabilia (an estate valued at more than five pounds sterling) in two dioceses or in two peculiars in the province of Canterbury or within two provinces (i.e., York and Canterbury). The Court of the Archbishop of Canterbury also had jurisdiction over all those with property in England, Wales, Isle of Man, or the Channel Islands who dies at sea or overseas. Such persons are distinguished in the calendars by the entry "pts," abbreviation for " parts overseas." instead of the name of the place. During the Commonwealth period from 1653 to 1660 the court, in the form of a civil court, had sole testamentary jurisdiction over all of England and Wales. Since the Reformation it has been usual for the estates of men of wealth and position to receive grants of probate and letters of administration in this court. During vacancies in this court between 997 and 1590, some wills were proved in the Court of the Dean and Chapter of Canterbury Cathedral (also known as the Court of the Prior and Chapter of Christ Church), Canterbury, Kent.
