[PAULUS libro tertio ad edictum. ] §2.14.17.prSi tibi decem dem et paciscar, ut uiginti mihi debeantur, non nascitur obligatio ultra decem: re enim non potest obligatio contrahi, nisi quatenus datum sit. §2.14.17.1Quaedam actiones per pactum ipso iure tolluntur: ut iniuriarum, item furti. §2.14.17.2De pignore iure honorario nascitur ex pacto actio: tollitur autem per exceptionem, quotiens paciscor ne petam. §2.14.17.3Si quis paciscatur, ne a se petatur, sed ut ab herede petatur, heredi exceptio non proderit. §2.14.17.4Si pactus sim, ne a me neue a Titio petatur, non proderit Titio, etiamsi heres extiterit, quia ex post facto id confirmari non potest.
[PAULUS, On the Edict, book 3]\n\nIf I give you ten and agree that twenty should be owed to me, no obligation arises beyond ten; for an obligation cannot be contracted by the delivery of a thing, except in so far as it has been given.\n\nCertain actions are extinguished by operation of law through an agreement, such as the action for injury, and likewise the action for theft.\n\nRegarding a pledge, an action arises from an agreement under praetorian law; however, it is barred by a plea whenever I agree not to sue.\n\nIf someone agrees that a claim shall not be made against himself, but that it may be made against his heir, the plea will not benefit the heir.\n\nIf I have agreed that a claim shall not be made against me nor against Titius, it will not benefit Titius, even if he becomes the heir, because it cannot be validated by a subsequent fact.
hoc Iulianusbscribit in patre, qui pactus erat, ne a se neue a filia peteretur, cum filia patri heres extitisset. §2.14.17.5Pactum conuentum cum uenditore factum si in rem constituatur, secundum plurium sententiam et emptori prodest, et hoc iure nos uti Pomponius scribit: secundum Sabini autem sententiam etiam si in personam conceptum est, et in emptorem ualet: qui hoc esse existimat et si per donationem successio facta sit. §2.14.17.6Cum possessor alienae hereditatis pactus est, heredi, si euicerit, neque nocere neque prodesse plerique putant. §2.14.17.7Filius seruusue si paciscantur, ne a patre dominoue petatur,
Julian writes this in the case of a father who had agreed that a claim should not be made against himself nor against his daughter, when the daughter had become the heir to her father.\n\nIf an agreement made with a seller is framed in rem, according to the opinion of the majority it also benefits the buyer, and Pomponius writes that we follow this rule; but according to the opinion of Sabinus, even if it is conceived in personam, it is also valid in favor of the buyer, and he thinks that this is the case even if the succession has occurred through a donation.\n\nWhen the possessor of another's inheritance has made an agreement, most authorities think that it neither prejudices nor benefits the heir, if the latter evicts him.\n\nIf a son or a slave agrees that a claim shall not be made against the father or the master,
