[IAUOLENUS libro secundo ad Plautium. ] §45.3.34.prSi seruus testamento manumissus, cum se liberum esse ignoraret et in causa hereditaria maneret, pecuniam heredi stipulatus est, nihil debebitur heredibus, si modo scierint eum testamento manumissum, quia non potest uideri iustam seruitutem seruisse iis, qui illum liberum esse non ignorabant.
[JAVOLENUS, from the second book on Plautius.] If a slave who has been manumitted by will, while being ignorant of his freedom and remaining in the capacity of an heir, has stipulated for money for the heir, nothing will be owed to the heirs, provided they knew that he had been manumitted by will; because he cannot be deemed to have served a lawful servitude to those who were not ignorant that he was free.
distat ista causa eius, qui liber emptus bona fide seruit, quia in eo et ipsius et emptoris existimatio consentit: ceterum is, qui scit hominem liberum esse, quamuis ille condicionem suam ignoret, ne possidere quidem eum potest uideri.
This case differs from that of one who, being a free man, was bought and serves in good faith, because in that case the opinion of both the person himself and the purchaser agrees; but he who knows that a man is free, although that man is ignorant of his own condition, cannot be deemed even to possess him.
