Courtesy title

A courtesy title is a form of address in the British peerage system used for wives, children, and other close relatives of a peer. These styles may mislead those unacquainted with the system into thinking that they have substantive titles.

Divorced wives

The divorced wife of a peer will put her Christian name before her husband's title, and lose any style she gained from marriage, and loses any address she gains from that style. So, "Her Grace The Duchess of London" becomes "Mary, Duchess of London," and should be addressed as "Duchess," but no longer "Your Grace." "The Rt. Hon. The Lady London" becomes "Mary, Lady London" and should be addressed as "Lady London," but not "My Lady" (an address gained from the style of Ladyship).
