[ULPIANUS libro quadragensimo primo ad Sabinum. ] §13.7.4.prSi conuenit de distrahendo pignore siue ab initio siue postea, non tantum uenditio ualet, uerum incipit emptor dominium rei habere.
[ULPIAN, on Sabinus, Book XLI] If there is an agreement concerning the sale of the pledge, whether from the beginning or afterwards, not only is the sale valid, but the buyer begins to have the ownership of the thing.
sed etsi non conuenerit de distrahendo pignore, hoc tamen iure utimur, ut liceat distrahere, si modo non conuenit, ne liceat.
But even if there has been no agreement concerning the sale of the pledge, we nevertheless apply this rule of law, that it is permitted to sell it, provided only that there was no agreement that it should not be permitted.
ubi uero conuenit, ne distraheretur, creditor, si distraxerit, furti obligatur, nisi ei ter fuerit denuntiatum ut soluat et cessauerit.
However, where it was agreed that it should not be sold, if the creditor sells it, he is liable for theft, unless the debtor has been three times summoned to pay and has failed to do so.
