Normally one refers to or addresses Baron [X] as Lord [X] and his wife as Lady [X].[6][8][9] Women who hold baronies in their own right may be styled as Baroness [X],[9] or Lady [X].[10][11] In direct address, they can also be referred to as My Lord, Your Lordship, or Your Ladyship, but never as My Lady (except in the case of a female judge). The husband of a Baroness in her own right gains no title or style from his wife. Children of Barons and Baronesses in their own right, whether hereditary or for life, have the style The Honourable [Forename] [Surname]. After the death of the father or mother, the child may continue to use the style The Honourable.
Barons are styled The Right Honourable The Lord [Barony].[6] Barons' wives are styled The Right Honourable The Lady [Barony]. Baronesses in their own right, whether hereditary or for life, are either styled The Right Honourable The Baroness [Barony] or The Right Honourable The Lady [Barony], mainly based on personal preference (e.g., Margaret, Baroness Thatcher and Brenda, Lady Hale, both created baronesses in their own right for life). Note the order of the names: 'Lady Brenda Hale' would denote that she were the daughter of an earl, marquess or duke and, in the case of men, 'Lord Digby Jones' would denote that he were the younger son of a marquess or duke, and should be properly styled "The Lord Jones of Birmingham" (or, less formally: "Digby, Lord Jones"). The Right Honourable is frequently abbreviated to The Rt Hon. or Rt Hon. When referred to by the Sovereign in public instruments, The Right Honourable is changed to Our right trusty and well-beloved, with Counsellor attached if they are a Privy Counsellor.
Courtesy barons are styled Lord [Barony], and their wives Lady [Barony]: the article "The" is always absent; if the courtesy baron is not a Privy Counsellor, the style The Right Honourable will also be absent.
