[IDEM libro decimo ad Sabinum. ] §19.1.7.prFundum mihi cum uenderes deducto usu fructu, dixisti eum usum fructum Titii esse, cum is apud te remansurus esset.
[THE SAME, on Sabinus, Book 10] When you sold me a land with the usufruct deducted, you said that the usufruct belonged to Titius, although it was to remain with you.
si coeperis eum usum fructum uindicare, reuerti aduersus te non potero, donec Titius uiuat nec in ea causa esse coeperit, ut, etiamsi eius usus fructus esset, amissurus eum fuerit: nam tunc, id est si capite deminutus uel mortuus fuerit Titius, reuerti potero ad te uenditorem.
If you should begin to claim that usufruct, I shall not be able to turn back against you as long as Titius is alive and has not begun to be in such a position that, even if the usufruct had been his, he would have lost it; for then, that is, if Titius has suffered a change of status or died, I shall be able to turn back against you, the seller.
idemque iuris est, si dicas eum usum fructum Titii esse, cum sit Sei.
And the same rule of law applies if you should say that the usufruct belonged to Titius, although it belongs to Seius.
