[GAIUS libro singulari de casibus. ] §28.5.89.prEi qui soluendo non est aliquo casu euenit, ut et seruus cum libertate heres exsistat et praeterea alius heres adiciatur: ueluti si seruo cum libertate herede instituto ita adiectum sit: 'si mihi Stichus heres erit, tunc Titius quoque heres esto': nam Titius, antequam Stichus ex testamento heres exstiterit, heres esse non potest, cum autem semel heres exstiterit seruus, non potest adiectus efficere, ut qui semel heres exstitit desinat heres esse.
[GAIUS, in the single book on Cases.] For one who is insolvent, it happens in some case that both a slave becomes heir with freedom, and besides, another heir is added: as for instance, if to a slave appointed heir with freedom there has been added: 'If Stichus is my heir, then let Titius also be heir'; for Titius, before Stichus has become heir under the will, cannot be heir, but when once the slave has become heir, the added person cannot bring it about that he who has once become heir should cease to be heir.
