[POMPONIUS libro sexto ex Plautio. ] §12.1.12.prSi a furioso, cum eum compotem mentis esse putares, pecuniam quasi mutuam acceperis eaque in rem tuam uersa fuerit, condictionem furioso adquiri Iulianus ait: nam ex quibus causis ignorantibus nobis actiones adquiruntur, ex isdem etiam furioso adquiri.
[POMPONIUS, On Plautius, Book 6] If you receive money from an insane person as if it were a loan, while you believe him to be of sound mind, and it is turned to your profit, Julian says that a personal action for recovery is acquired for the insane person; for, from the same causes by which actions are acquired for us without our knowledge, they are also acquired for an insane person.
item si is qui seruo crediderat furere coeperit, deinde seruus in rem domini id uerterit, condici furiosi nomine posse.
Likewise, if one who had loaned money to a slave begins to be insane, and then the slave turns it to the profit of his master, a recovery can be sought in the name of the insane person.
et si alienam pecuniam credendi causa quis dederit, deinde furere coeperit et consumpta sit ea pecunia, condictionem furioso adquiri.
And if someone gives another's money for the purpose of loaning it, and then begins to be insane, and that money is consumed, a personal action for recovery is acquired for the insane person.
