<P> For example, the Duke of Norfolk is also Earl of Arundel and Baron Maltravers . His eldest son is therefore styled "Earl of Arundel" (without the definite article "The" which indicates a substantive title). Lord Arundel's eldest son (should he have one during his father's lifetime) would be styled "Lord Maltravers". However, only The Duke of Norfolk is actually a peer; his son Lord Arundel and his hypothetical grandson Lord Maltravers are not . </P> <P> Courtesy titles are only used by the peer's eldest living son, and the eldest son's eldest living son, and so forth . Other descendants are not permitted to use the peer's subsidiary titles . Only the heir apparent (and heir apparent to the heir apparent, and so on) may use them . An heir presumptive (e.g., a brother, nephew, or cousin) does not use a courtesy title . However, Scottish practice allows the style Master / Mistress of X to an heir presumptive as well as to an heir apparent; for example, the brother of the present Marquess of Tweeddale has the title Master of Tweeddale . </P> <P> Wives are entitled to use the feminine form of their husbands' courtesy titles . Thus, the wife of an Earl of Arundel would be styled "Countess of Arundel" (again, without the article). </P> <P> Holders of courtesy titles do not, at the Court of St James's, have their title preceded by the definite article "The" (which is always written with the capital letter "T"): e.g.,' Earl of Arundel' rather than' The Earl of Arundel' . </P>
