Scottish Barons rank below Lords of Parliament, and although they are titles of nobility, they are not peerage titles.

In showing that Scottish barons are titles of nobility, reference may be made, amongst others, to Lyon Court in the Petition of Maclean of Ardgour for a Birthbrieve by Interlocutor dated 26 February 1943 which "Finds and Declares that the Minor Barons of Scotland are, and have both in this Nobiliary Court, and in the Court of Session, been recognised as 'titled' nobility, and that the estait of the Baronage (The Barones Minores) is of the ancient Feudal Nobility of Scotland".

Sir Thomas Innes of Learney in his 'Scots Heraldry' (2nd Ed., p. 88, note 1) states that 'The Act 1672, cap 47, specifically qualifies the degrees thus: Nobles (i.e. peers, the term being here used in a restricted seventeenth-century English sense), Barons (i.e. Lairds of baronial fiefs and their "heirs", who, even if fiefless, are equivalent to heads of Continental baronial houses) and Gentlemen (apparently all other armigers).' Baronets and knights are evidently classed as 'Gentlemen' here and are of a lower degree than Barons.
