[IDEM libro quinto ex Plautio. ] §46.2.24.prNouatio non potest contingere ea stipulatione, quae non committitur.
[THE SAME, On Plautius, Book 5.] Novation cannot take place by a stipulation that is not realized.
nec huic contrarium est, quod, si stipulatus a Titio fuero nouandi animo sub condicione, quod mihi Sempronius debet, et pendente condicione Titius decesserit, quamuis ante aditam hereditatem condicio exstiterit, nouatio fieret: hic enim morte promissoris non extinguitur stipulatio, sed transit ad heredem cuius personam interim hereditas sustinet.
Nor is it contrary to this that, if I have entered into a stipulation with Titius under a condition, with the intention of novating what Sempronius owes me, and Titius dies while the condition is pending, even if the condition is realized before the inheritance is accepted, a novation would take place: for here the stipulation is not extinguished by the death of the promisor, but passes to the heir, whose person the inheritance meanwhile sustains.
