[SCAEUOLA libro secundo quaestionum. ] §14.6.6.prContra etiam recte dicetur, si a patre familias stipulatus sit, credas postea filio familias facto, senatus potestatem exercendam, quia expleta est numeratione substantia obligationis.
[SCAEVOLA, Questions, Book 2] On the other hand, it will also be rightly said that, if one has stipulated with a head of a household and subsequently lends money to him after he has become a son under paternal power, the authority of the senate's decree must be enforced, because the substance of the obligation is completed by the paying out of the money.
