[ULPIANUS libro trigensimo quarto ad Sabinum. ] §12.1.4.prSi quis nec causam nec propositum faenerandi habuerit et tu empturus praedia desideraueris mutuam pecuniam nec uolueris creditae nomine antequam emisses suscipere atque ita creditor, quia necessitatem forte proficiscendi habebat, deposuerit apud te hanc eandem pecuniam, ut, si emisses, crediti nomine obligatus esses, hoc depositum periculo est eius qui suscepit.
[ULPIAN, On Sabinus, book 34] If someone has neither the cause nor the purpose of lending at interest, and you, intending to buy estates, have desired a loan of money, but have not wished to receive it under the name of a loan before you have bought them, and thus the creditor, because he happened to have the necessity of departing, has deposited this same money with you, so that, if you should buy them, you would be bound under the name of a loan, this deposit is at the risk of him who received it.
nam et qui rem uendendam acceperit, ut pretio uteretur, periculo suo rem habebit.
For he also who has received a thing to be sold, in order that he might use the price, will hold the thing at his own risk.
§12.1.4.1Res pignori data pecunia soluta condici potest.
A thing given in pledge can be recovered by condictio once the money has been paid.
et fructus ex iniusta causa percepti condicendi sunt: nam et si colonus post lustrum completum fructus perceperit, condici eos constat ita demum, si non ex uoluntate domini percepti sunt: nam si ex uoluntate, procul dubio cessat condictio.
And fruits gathered from an unjust cause must be recovered by condictio; for even if a tenant farmer, after the completion of a five-year term, has gathered fruits, it is well established that they can be recovered by condictio, but only if they were not gathered with the consent of the owner; for if they were gathered with his consent, without a doubt the condictio does not lie.
§12.1.4.2Ea, quae ui fluminum importata sunt, condici possunt.
Those things which have been brought in by the force of rivers can be recovered by condictio.
