[ULPIANUS libro sexagesimo tertio ad edictum. ] §40.5.7.prSi cui legata sint centum ita, ut seruum alienum redimat et manumittat, et bonis heredis uenditis partem, non totum persequatur, non alias debet consequi legatum, quam si cauerit se manumissurum (sed hoc tunc demum, si largiatur portio quam accepit ad serui pretium paratusque sit dominus tanti eum uendere): alioquin exceptione doli debebit legatarius repelli.
[ULPIANUS in the sixty-third book on the Edict.] If one hundred [units] have been bequeathed to someone on the condition that he purchase and manumit another's slave, and, the property of the heir having been sold, he recovers only a part and not the whole, he ought not to obtain the legacy otherwise than if he has given security that he will manumit him (but this only if the portion which he received is sufficient for the price of the slave, and the owner is prepared to sell him for that price); otherwise, the legatee must be repelled by the plea of fraud.
