The first Civil Code was written by Argentine juristDalmacio Vélez Sársfield, and came into effect on January 1, 1871 and remained law until 1 August 2015, when it was replaced by a new Civil and Commercial Code - Código Civil y Comercial de la Nación.[1][2]
The 1871 Argentine Civil Code was largely inspired by the Spanish legal tradition, and also by the Brazilian Civil Code, the Spanish Civil Code of 1851, the Napoleonic code and the Chilean Civil Code. The sources of this Civil Code also include various theoretical legal works, mainly of the great French jurists of the 19th century. It was the first Civil Law that consciously adopted as its cornerstone the distinction between rights and obligations and real property rights, thus distancing itself from the French model.
The new Código Civil y Comercial de la Nación[3] brings many changes, in particular the modernization of family law.[4]
