The Judiciary of England and Wales contains many levels, based on the court in which the judge sits. Titles are given to judges relating to their position and, in the case of knighthoods and peerages, this includes the positions they had previously held. Retired judges that sit in any court use their full name with their titles added (such as Sir or Dame, or post-nominal QC). Due to the various honours bestowed on members of the judiciary and traditions associated with the varying levels, their personal titles and forms of address often change as they progress in a judicial career.
