[IDEM libro trigensimo quarto ad Sabinum. ] §46.2.5.prIn diem obligatio nouari potest et prius quam dies aduenerit.
[THE SAME, in the thirty-fourth book on Sabinus.] An obligation subject to a time limit can be novated even before the day arrives.
et generaliter constat et stipulatione in diem facta nouationem contingere, sed non statim ex ea stipulatione agi posse, antequam dies uenerit.
And it is generally established that a novation also occurs when a stipulation is made subject to a time limit, but that an action cannot be brought immediately on that stipulation before the day arrives.
