In order to comply with his will and testament, a Board of Trustees was constituted by Spanish Ministerial Order of 22 March 1934.
The Board of Trustees, which meets at least twice a year, is composed on the express wishes of the Marquis by “Ex Officio Trustees” the Cardinal Archbishop of Madrid, the President of the Supreme Court, the President of todays High Court of Justice of Madrid, the current Marquis of Cerralbo by virtue of their offices; and by a member to be freely designated by the Spanish Ministry of Culture.
