[PAULUS libro tertio ad legem Aeliam Sentiam. ] §45.1.66.prSi minor uiginti annis a debitore suo stipuletur 'seruum manumissurum', non est exsecutio stipulationis danda.
[PAULUS, On the Lex Aelia Sentia, Book 3] If a person under twenty years of age should stipulate from his debtor "that he will manumit a slave", the execution of the stipulation is not to be granted.
sed si ipsorum uiginti annorum erit, non impedietur manumissio, quia de minore lex loquitur.
But if he is of exactly twenty years of age, the manumission will not be hindered, because the law speaks of a minor.
