[IULIANUS libro undecimo digestorum. ] §13.5.23.prPromissor hominis homine mortuo, cum per eum staret quo minus traderetur, etsi hominem daturum se constituerit, de constituta pecunia tenebitur, ut pretium eius soluat.
[JULIANUS, from the eleventh book of the Digests.] The promisor of a slave, after the slave has died, if it was due to him that delivery was not made, even if he had promised that he would deliver the slave, will be liable under the action on promised money, so as to pay the price of the slave.
