[PAULUS libro sexagensimo nono ad edictum. ] §2.11.5.prSi duo rei stipulandi sint et uni debitor iudicio se sisti cum poena promiserit, alter autem impedierit: ita demum exceptio aduersus alterum danda est, si socii sint: ne prosit ei dolus propter societatem.
[PAULUS, in the sixty-ninth book on the Edict.] If there are two joint creditors, and the debtor has promised one of them, under penalty, to present himself in court, but the other has prevented him: an exception is to be granted against the other only if they are partners, lest his fraud benefit him because of the partnership.
§2.11.5.1Item si duo rei promittendi sint et unus ad iudicium non uenerit contempta sua promissione iudicio sistendi causa facta, actor autem ab altero rem petat, ab altero poenam desertionis: petendo poenam exceptione summouebitur.
Likewise, if there are two joint debtors, and one did not appear in court, in disregard of his promise made for the purpose of presenting himself in court, and the plaintiff seeks the main thing from one, and the penalty for default from the other: in seeking the penalty, he will be barred by an exception.
§2.11.5.2Aeque si a patre facta fuerit promissio iudicio sistendi gratia ex filii contractu, deinde de re actor egerit cum filio, exceptione summouebitur, si cum patre ex eius promissione agat.
Equally, if a promise to present [the son] in court was made by a father on account of a contract of his son, and then the plaintiff has sued the son concerning the main matter, he will be barred by an exception if he sues the father on his promise.
et contra idem erit, si filius promiserit et actor egerit cum patre de peculio.
And conversely, the same will apply if the son made the promise and the plaintiff has sued the father concerning the peculium.
