La. Civ. Code art. 213
Current with changes from the 2024 First and Second Extraordinary Sessions
The adoptive parent and the person to be adopted shall consent to the adoption in an authentic act of adoption.
The spouse of the adoptive parent and the spouse of the person to be adopted shall sign the act of adoption for the purpose of concurrence in the adoption only. The act of adoption without this concurrence is absolutely null. The concurrence does not establish the legal relationship of parent and child.
Neither a party to an adult adoption nor a concurring spouse may consent by procuration or mandate.
