Family of a Disclaimed Peer
Wife of a Disclaimed Peer
Immediately her husband disclaims his peerage she reverts to the same style as her husband. For example, if he becomes Mr John Jones she becomes Mrs John Jones. If her husband is also a baronet, or has been knighted, she may use the title of 'Lady Jones'.
Similarly, if she has a title in her own right, as the daughter of a peer, she may revert to its use (ie Lady Mary Jones, or The Hon Mrs Jones).
Children of a Disclaimed Peer
The children of a disclaimed peer retain their precedence as the children of a peer, and any courtesy titles and styles borne while their father was a peer. It is open to any child of a disclaiming peer to say that he or she no longer wishes to be known by these styles, eg the two sons and two youngest daughters of the late Victor Montagu (disclaimed Earl of Sandwich) decided to retain their titles, but his two eldest daughters decided not to. All the children of Tony Benn (disclaimed Viscount Stansgate) decided to drop their courtesy titles.
