[IULIANUS libro tertio decimo digestorum. ] §41.1.36.prCum in corpus quidem quod traditur consentiamus, in causis uero dissentiamus, non animaduerto, cur inefficax sit traditio, ueluti si ego credam me ex testamento tibi obligatum esse, ut fundum tradam, tu existimes ex stipulatu tibi eum deberi.
[JULIANUS, Digest, book 13] When we are indeed in agreement as to the actual object which is delivered, but differ as to the grounds, I do not see why the delivery should be ineffective; as for instance, if I believe that I am bound to you under a will to deliver a tract of land, while you think that it is owed to you under a stipulation.
nam et si pecuniam numeratam tibi tradam donandi gratia, tu eam quasi creditam accipias, constat proprietatem ad te transire nec impedimento esse, quod circa causam dandi atque accipiendi dissenserimus.
For even if I should deliver counted money to you for the sake of making a gift, and you should receive it as if it were a loan, it is clear that the ownership passes to you, and that the fact that we differed regarding the ground of giving and receiving is no obstacle.
