Datio In Adoptionem Law and Legal Definition

In Roman law, ‘datio in adoptionem’ means ‘given in adoption.’ Romans used the term adrogatio to refer to the adoption of one already of full age (sui juris). Datio in adoptionem occurred when one was given in adoption by a person having control or power over him/her.

Adoption is either arrogatio, when a man in his own right (homo sui juris) is adopted, or datio in adoptionem, when a filius familias of him who has such person in his power is given to another for adoption.
