Answer
Once the adoption order is issued, the adopted child is, for all intents and purposes, the legitimate child of the adopter, entitled to all the rights and obligations of a legitimate child. The legal ties between the child and the biological parents are severed and parental authority is transferred to the adopter — except where the adopter is the spouse of the biological parent.
The adoptee acquires reciprocal rights of succession with the adopter, without distinction from legitimate filiation, and is entitled to use the adopter's surname. These substantive effects are essentially the same as under the former law, so Supreme Court decisions on the effects of adoption remain instructive even though the process is now administrative.
