[ULPIANUS libro sexto regularum. ] §28.5.51.prSeruum meum heredem institutum cum libertate si uiuus uendidero ei, cum quo testamenti factio non est, posteaque eum redemero, ex testamento mihi heres esse poterit nec medium tempus, quo apud eum fuit, uitiauit institutionem, quia uerum est utroque tempore tam testamenti faciendi quam mortis tempore meum fuisse.
If, during my lifetime, I sell my slave who has been instituted heir with his freedom to someone with whom there is no testamenti factio, and I afterwards buy him back, he can be my heir under the will; nor does the intervening time, during which he was with that person, invalidate the institution, because it is true that he was mine at both times, both at the time of making the will and at the time of death.
unde si apud eum remanserit, uitiatur institutio: uel si cum eo testamenti factio est, iussu eius adeundo adquiret ei hereditatem.
Hence, if he remains with that person, the institution is invalidated; or, if there is testamenti factio with him, he will acquire the inheritance for him by entering upon it by his order.
§28.5.51.1Si in non faciendo impossibilis condicio institutione heredis sit expressa, secundum omnium sententiam heres erit, perinde ac si pure institutus esset. H
If an impossible condition in not doing something is expressed in the institution of an heir, according to the opinion of all he will be heir, just as if he had been instituted unconditionally.
§28.5.51.2ereditas plerumque diuiditur in duodecim uncias, quae assis appellatione continentur.
An inheritance is usually divided into twelve unciae, which are contained under the designation of an as.
habent autem et hae partes propria nomina ab uncia usque ad assem, puta haec: sextans quadrans triens quincunx semis septunx bes dodrans dextans deunx as.
Moreover, these parts also have their own names from the uncia up to the as, for example: sextans, quadrans, triens, quincunx, semis, septunx, bes, dodrans, dextans, deunx, as.
