Drafted by Saint Vicenta Maria in 1882 in Madrid, that all the Sisters of the Domestic Service must preserve it  dilligently with the grace of God and the protection of the Immaculate Virgin Mary, her principal protector in 1882.  These texts have historical and spiritual values though not legislative.  It finds  in them the spirit that inspired the Saint and continues  today in the renewed constitutions.  They put in evidence the continuity between " yesterday" and " today " from the same Charism, though, expressed in diverse language.

 The Practices and Customs for the Novitiate of the Religious of the Domestic Service of the Immaculate Conception, written in Barcelona in 1890 is also kept in the archive.
