[IDEM libro quinto decimo digestorum. ] §21.2.8.prUenditor hominis emptori praestare debet, quanti eius interest hominem uenditoris fuisse.
[THE SAME, Digests, book fifteen.] The seller of a slave must make good to the buyer how much it was of interest to him that the slave had belonged to the seller.
quare siue partus ancillae siue hereditas, quam seruus iussu emptoris adierit, euicta fuerit, agi ex empto potest: et sicut obligatus est uenditor, ut praestet licere habere hominem quem uendidit, ita ea quoque quae per eum adquiri potuerunt praestare debet emptori, ut habeat.
Therefore, whether it is the offspring of a female slave or an inheritance which the slave has entered upon by order of the buyer that is evicted, an action can be brought ex empto; and just as the seller is bound to guarantee that it is permitted to hold the slave whom he sold, so also he must guarantee to the buyer, so that he may hold them, those things which could have been acquired through him.
