[ULPIANUS libro uicesimo sexto ad edictum. ] §33.2.7.prOperae testamento relictae quando cedere debeant, utrum ex quo petit eas legatarius an ex quo adita hereditas est? et cui pereant dies, quibus aeger seruus fuit? et puto ex die petitionis eas cedere: quare si post petitas aeger esse seruus coeperit, legatario peribunt.
[ULPIAN, On the Edict, book XXVI.] When services bequeathed by a will ought to vest: whether from the time when the legatee claims them, or from the time when the inheritance was entered upon? And for whom are those days lost during which the slave was ill? And I think that they vest from the day of the claim; therefore, if after they have been claimed the slave begins to be ill, they will be lost to the legatee.
