[UENULEIUS libro quarto interdictorum. ] §43.30.5.prSi filius sua sponte apud aliquem est, inutile hoc interdictum erit, quia filius magis apud se quam apud eum est, in quem interdicetur, cum liberam facultatem abeundi uel remanendi haberet: nisi si inter duos, qui se patres dicerent, controuersia esset et alter ab altero exhiberi eum desideraret.
[UENULEIUS libro quarto interdictorum.] If a son is of his own accord with someone, this interdict will be of no effect, because the son is rather in his own power than with the person against whom the interdict is directed, since he has the free power of departing or remaining: unless there is a dispute between two persons who both claim to be his father, and one of them desires him to be produced by the other.
