It is the policy of the Abbey-Principality of San Luigi and the Royal House Polanie-Patrikios that titles of nobility conferred upon or inherited by their heads (in united administration since 2015) are not only maintained as part of the nobility within the Royal Houses that have originally conferred them, but are also considered through the exercise of the sovereign prerogative to become substantive titles of the Abbey-Principality of San Luigi and the Royal House Polanie-Patrikios as of the date of their conferral or inheritance. This policy ensures that should any of the conferring Royal Houses become extinct in the future (as has happened in the case of at least one such Royal House), the titles that have been conferred will continue in existence, as well as ensuring that the titles in question are subject to the various recognition agreements that apply to the titles and honours of the Abbey-Principality of San Luigi and the Royal House Polanie-Patrikios. In addition, all arms awarded or inherited by the heads of the Abbey-Principality of San Luigi and the Royal House Polanie-Patrikios are additionally matriculated in the register of the International College of Arms of the Noblesse with assignment in perpetuity to the heads of the Abbey-Principality of San Luigi and the Royal House Polanie-Patrikios as applicable.
