[ULPIANUS libro septimo decimo ad Sabinum. ] §7.3.1.prQuamquam usus fructus ex fruendo consistat, id est facto aliquo eius qui fruitur et utitur, tamen semel cedit dies: aliter atque si cui in menses uel in dies uel in annos singulos quid legetur: tunc enim per dies singulos uel menses uel annos dies legati cedit.
[ULPIANUS from the seventeenth book on Sabinus.] Although a usufruct consists in enjoying (that is, in some act of the person who enjoys and uses), nevertheless its day cedes once and for all: unlike when something is bequeathed to someone for individual months, days, or years, for in that case the day of the legacy cedes for individual days, months, or years.
unde quaeri potest, si usus fructus cui per dies singulos legetur uel in annos singulos, an semel cedat: et puto non cedere simul, sed per tempora adiecta, ut plura legata sint: et ita libro quarto digestorum Marcellus probat in eo, cui alternis diebus usus fructus legatus est.
Hence it can be asked, if a usufruct is bequeathed to someone for individual days or years, whether it cedes once and for all; and I think it does not cede all at once, but rather at each added period, as if there were multiple legacies. And Marcellus approves this in the fourth book of his Digests in the case of a person to whom a usufruct was bequeathed on alternate days.
§7.3.1.1Et ideo si is fructus legatus sit, qui cottidie percipi non potest, non erit inutile legatum, sed dies habebunt legatum, quibus frui potest.
And therefore, if a usufruct is bequeathed which cannot be gathered daily, the legacy will not be invalid, but the legacy will apply to those days on which it can be enjoyed.
§7.3.1.2Dies autem usus fructus, item usus non prius cedet quam hereditas adeatur: tunc enim constituitur usus fructus, cum quis iam frui potest.
However, the day of a usufruct, and likewise of a use, does not cede before the inheritance is accepted; for a usufruct is established only when someone is already able to enjoy it.
hac ratione et si seruo hereditario usus fructus legetur, Iulianus scribit, quamuis cetera legata hereditati adquirantur, in usu fructu tamen personam domini exspectari, qui uti et frui possit.
For this reason, Julian writes that even if a usufruct is bequeathed to a hereditary slave, although other legacies are acquired for the inheritance, in the case of a usufruct, however, the person of a master who can use and enjoy is awaited.
§7.3.1.3Item si ex die usus fructus legetur, dies eius nondum cedet, nisi cum dies uenit: posse enim usum fructum ex die legari et in diem constat.
Likewise, if a usufruct is bequeathed from a certain day, its day does not yet cede until that day arrives; for it is well established that a usufruct can be bequeathed from a certain day or until a certain day.
§7.3.1.4Non solum autem usus fructus ante aditam hereditatem dies non cedit, sed nec actio de usu fructu: idemque et si ex die fuerit legatus usus fructus: denique Scaeuola ait agentem ante diem usus fructus nihil facere, quamuis alias qui ante diem agit, male agit.
Not only does the day of a usufruct not cede before the inheritance is accepted, but neither does the action concerning the usufruct; and the same applies if the usufruct has been bequeathed from a certain day. Finally, Scaevola says that one who brings an action before the day of the usufruct accomplishes nothing, although in other cases, one who sues before the day loses his case.
