Múltiple filiación en Argentina: Ampliando los límites del parentesco.

The article analyzes the legal recognition before an administrative authority of the triple affiliation of a child occurred in Argentina in the year 2015. The case, carried out by the organization ?Lawyers for Sexual Rights (AboSex)?, was the second precedent in the country and entailed the recognition, through the competent administrative authority, of a family composed of two mothers, a father and a child. The arguments of the case were based on constitutional and international law rights as the right to family and family life without illegal or arbitrary interference, the right to the identity of the child, respect for his best interest, and the procreational will of the parents, until then not recognized by national laws.
