Pomponius, On Plautius, Book II. Where an agent is appointed for the collection of a legacy, and makes use of an interdict against the heir for the production of the will, an exception against the agent on the ground that he is not authorized to do this by the mandate, cannot be pleaded against him.

Pomponius, On Plautius, Book II. Where property which I purchased from Titius is bequeathed by me, and the legatee is sued by the owner of the same, he cannot notify my vendor of the eviction, unless the rights of action should be assigned to him, or where he has the property secured by hypothecation.

Pomponius, On Plautius, Book II. If you purchase a tract of land from Titius, which in fact belonged to Sempronius, and after the price was paid he delivers it to you, and Titius then becomes the heir of Sempronius, and sells and delivers the same land to Mævius; Julianus says that it is more equitable, for you have the prior lien, because if Titius himself had attempted to recover the land from you, he would have been barred by an exception; and if Titius himself had held possession of it, you could have recourse to the Publician Action.
