[ULPIANUS libro trigensimo secundo ad edictum. ] §18.4.4.prSi nomen sit distractum, Celsus libro nono digestorum scribit locupletem esse debitorem non debere praestare, debitorem autem esse praestare, nisi aliud conuenit,
[ULPIANUS, on the Edict, book 32.] If a claim has been sold, Celsus writes in the ninth book of his Digests that the seller is not bound to guarantee that the debtor is solvent, but must guarantee that there is indeed a debtor, unless it has been agreed otherwise.
