Addressing Titled People
Below are details of the correct way to address a letter to a titled person, and how to start and end the letter. For a more detailed list consult "Who's Who" by A & C Black (Publishers) Ltd. or "Debrett's People of Today" by Debrett's Peerage Ltd. Alternatively, you could contact the individuals secretary for advice, not only on how to address the titled person in writing, but also how to address and introduce the titled individual when meeting them in person.
Unless you know the Queen and other members of the Royal Family personally, letters should not be sent directly to the individual, but rather to their respective Personal Secretary.
In order to use the correct mode of address, you will need to know the individuals correct title. For example a Peer, (ie. a Lord) is a person who holds any one of the five grades of the British nobility, ie Duke, Marquess, Earl, Viscount and Baron.
The title of a Peer's Wife, Son and Daughter (and their spouses) sometimes vary dependent on whether they are married or not, and whether their spouse is a Peer or not. In such cases, referring to "Who's Who" or "Debrett's People of Today" will help.
The title "Sir" is not only used by a Knight Bachelor and Knights of an Order of Chivalry, but also by Baronets. Again, referring to "Who's Who" or "Debrett's People of Today" will help.
When sending a joint invitation to married couples at their home address, the envelope should always be addressed to the Wife.
