Disputation IV: On Donation
DONATION also is as it were a contract, therefore we treat of it after promise; but both are called as it were contracts, because they proceed from mere liberality, and place the obligation on one side only, in whose power it is to annul it, until the thing donated, or promised, passes into the power of the other. But lest there be too great license in giving, or rather in throwing away one's goods, the Laws determine the manners and the persons in which donations are valid.
DONATIO etiam est quasi contractus, ideo post promissionem de ea agimus; dicuntur vero ambae quasi contractus, quia ex sola liberalitate procedunt, ponuntque obligationem in una sola parte, penes quam est illam irritare, donec res donata, vel promissa in alterius transeat potestatem. Verum ne nimia esset licentia donandi, seu potius bona lapidandi, Iura modos, et personas determinant, in quibus donationes sint validae.
