[IDEM libro nono ad Plautium. ] §41.1.49.prQuod fructuarius ex re sua donat, ex re eius est: sed si eo animo id fecerit, ut ad proprietatis dominum pertineat, dicendum est illi adquiri.
[THE SAME, from the Commentary on Plautius, book 9] What a usufructuary donates from his own property (to the slave) is (held to be) from his own property (and thus acquired for him); but if he does so with the intention that it should belong to the owner of the property, it must be said to be acquired for the latter.
si autem extraneus ei donet indistincte, soli proprietario adquiritur.
If, however, a stranger donates to him (the slave) without distinction, it is acquired for the owner alone.
eadem dicemus in homine libero, qui bona fide mihi seruit, ut, si ei aliquid donauerim, meum sit.
We shall say the same in the case of a free man who serves me in good faith, so that, if I donate something to him, it remains mine.
et ideo Pomponius scribit, quamuis donauerim ei operas suas, tamen quidquid ex operis suis adquiret, mihi adquiri.
And therefore Pomponius writes that, although I may have donated his own labor to him, nevertheless, whatever he acquires from his labor is acquired for me.
