Filiation is, in a broad sense, an identity element, dependent or not on the biological relationships, that represents, in some situations, either a condition for the existence of a right (e.g. the right to inheritance) or for example to conclude a legal act (e.g. marriage). The proof of filiation is the birth certificate drawn up in civil registry or on the material basis of birth, or on the basis of the adoption judgment. In this paper, we aimed at analyzing the final part of the adoption procedure, the subsequent stage for becoming final the adoption judgment, which sets face to face the adopting person or family and the administrative authority, obliged to execute the judge's decision, i.e. to create a filiation relation between the adopted on the one hand and the adoptive parent or parents.
