[ULPIANUS libro septuagesimo tertio ad edictum. ] §20.1.10.prSi debitor res suas duobus simul pignori obligauerit ita, ut utrique in solidum obligatae essent, singuli in solidum aduersus extraneos Seruiana utentur: inter ipsos autem si quaestio moueatur, possidentis meliorem esse condicionem: dabitur enim possidenti haec exceptio: 'si non conuenit, ut eadem res mihi quoque pignori esset. ' si autem id actum fuerit, ut pro partibus res obligarentur, utilem actionem competere et inter ipsos et aduersus extraneos, per quam dimidiam partis possessionem adprehendant singuli.
[ULPIAN, in the seventy-third book on the Edict.] If a debtor should pledge his property to two persons at the same time in such a way that it is obligated to each for the whole amount, each of them will bring the Servian action for the whole against third parties; but if a dispute should arise between themselves, the condition of the possessor is the better; for the possessor will be granted this exception: 'unless it was agreed that the same thing should also be pledged to me.' But if it was agreed that the things should be pledged for their respective shares, a useful action is available both between themselves and against third parties, by which each may acquire possession of a half share.
