Quaestionum libri
Fragmenta incerta
Dig. 34,6,1Africanus libro ..... quaestionum. Filio familias vel servo herede instituto etiam si in patris dominive poenam illicite vel probrose datum est, nullius momenti legatum esse respondit: non enim id solum, quod in heredes, sed omne, quod in cuiusque lucrum aliquid ex ultima voluntate sentientis talem poenam in testamento scriptum sit, nullius momenti habendum.
Africanus, Questions. Where a son under paternal control or a slave is appointed an heir, and the testator also illegally or insultingly bequeaths a legacy which will operate as a penalty against the father or the master, it has been held that the legacy is of no force or effect; for every bequest included in a will which is prompted by a desire for revenge, whether it is left to an heir or to anyone else who derives benefit from the last will of the testator, must be considered void.
