[ULPIANUS libro quinquagensimo tertio ad edictum. ] §39.2.11.prQuid de creditore dicemus, qui pignus accepit? utrum repromittere, quia suum ius tuetur, an satisdare, quia dominus non est, debebit? quae species est in contrario latere apud Marcellum agitata, an creditori pigneraticio damni infecti caueri debeat.
[ULPIAN on the edict, book 53.] What shall we say of a creditor who has received a pledge? Will he have to promise, because he is protecting his own right, or to give security, because he is not the owner? This case is discussed by Marcellus from the opposite side, namely, whether security for threatened damage should be provided to a pledge creditor.
et ait Marcellus inutiliter ei caueri: idemque etiam de eo cauendum qui non a domino emit: nam nec in huius persona committi stipulationem.
And Marcellus says that security is provided to him to no purpose; and that the same must be said of providing security for one who did not buy from the owner; for in the person of this latter also, the stipulation does not take effect.
aequissimum tamen puto huic prospiciendum, id est creditori, per stipulationem.
I think it most equitable, however, that provision should be made for this person, that is, for the creditor, by means of a stipulation.
