Foreign Ministers and Envoys take precedence next after dukes, in the order of their seniority of service in England. In all cases where precedency is to be established between persons of equal rank it is necessary to refer to a Peerage for date of creation of title, as this actually decides all precedency.
For Precedency due to Baronets and their wives a Baronetage should be consulted.
For Precedency due to Knights and their wives a Knightage should be consulted in reference to each order of knighthood.
For the Precedency due to the Legal Profession a Law List should be consulted when it is not defined by office or birth.
For the Precedency due to the Clergy a Clergy List should be consulted when superior preferment or birth does not define it.
