The organizations through which charities are operated are a Protectorate and Provincial and Municipal Committees. To the Protectorate, directed by the minister of the Interior and the president of the Council, pertain the functions of classifying, creating, enlarging, or modifying the various charitable institutions, the distribution of surplus funds, the authorization of representatives of the institutions to have recourse to courts of justice and to sell property, the appointment and suspension, dissolution and reorganization of committees (juntas), authorization of transfers of scrip in the public debt, approval of statements and accounts, etc. The juntas, as subordinate organs, have only to co-operate with the protectorate, acting as agents and distributors of the property of the various institutions.

Radical and sweeping reforms were introduced and carried through by Señor La Cierva. He began by reorganizing the protectorate, giving it a more numerous and better qualified personnel, creating the "Junta Superior de Beneficencia" to assist the Protectorate, and constituting a special bureau for the management of expenditures, liquidations, and savings effected by it in favour of the charitable institutions. Another measure was the formation of archives, provincial and municipal, with corresponding indexes, giving a great deal of correct, though incomplete, statistics, to serve as a basis for the knowledge of the work done in behalf of charity, the number, capital, and patronage of the various charitable institutions. In this way the Protectorate is ably assisted in the performance of its important duties.
