Royal warrant of precedence

A royal warrant of precedence is a warrant issued by the monarch of the United Kingdom to determine precedence amongst individuals or organisations. The rank of precedence may have an associated courtesy title.

Most warrants of this type are issued when the heir to a title predeceases the current holder of the title. The widow, daughter, or younger son of the deceased will not be entitled to the rank of "wife/daughter/younger son of [rank of the relevant title]" unless such a warrant is granted. The warrants are usually issued to the following effect:

The King/Queen has been pleased to ordain that <name> shall henceforth have, hold and enjoy the title, rank, place, pre-eminence and precedence as the younger son/daughter of a duke/marquess/earl etc. which would have been due to him/her had his/her father, <name>, survived his <e.g. brother>, <name and title>, and thereby succeeded to the said title and dignity of Duke/Marquess/Earl etc. of Somewhere. And to command that the said Royal Concession and Declaration be recorded in His/Her Majesty's College of Arms [and also in His/Her Majesty's Lyon Office if a Scottish title].

Below is a list of such warrants in descending order of rank (note: the Orders of Precedence for males and females are separate from one another):
