According to the British government, the current policy of using noble titles on passports requires that the applicant provides evidence that the Lord Lyon has recognised a feudal barony, or the title is included in Burke's Peerage. If accepted (and if the applicant wishes to include the title), the correct form is for the applicant to include the territorial designation as part of their surname (Surname of territorial designation e.g. "Smith of Inverglen"). The official observation would then show the holder's full name, followed by their feudal title e.g. "The holder is John Smith, Baron of Inverglen".
