De legatis positiones

XIIX.
Those who are joined by thing and words, or by the thing alone, if all of them come to the legacy, the legacy is divided among them: if one or more should fail, the shares of those who fail will accrue to the others in proportion.

XIX.
Regarding those, however, who are joined by words alone, it must be known that they are not in a worse condition than the others, provided that the testator did not wish to join them so much as to speak quickly.

XX.
Furthermore, all things that are objects of commerce can be bequeathed.

XXI.
And not only corporeal things, such as a house, a plot of land, furniture: but also incorporeal ones, such as a debt, a release, a usufruct, a dowry, etc.

XXII.
But even the things of others can be bequeathed, provided that the testator knows they belong to another: which must be proven by the legatee.

XXIII.
For then the heir is understood to be condemned to redeem them if he can at a just price, or if he cannot, to provide their valuation.

XXIV.
Nor does it matter whether they are free or obligated to a creditor: for the heir is compelled to redeem them: unless the testator has provided that the legatee should do so.

XXV.
Indeed, even things that are not yet in the nature of things, but will be, can be bequeathed: such as the fruits of trees, the offspring of cattle, and the like.

XXVI.
And the accretion of a thing always yields to the legacy, as does the decrease.
