[PAPINIANUS libro decimo quaestionum. ] §24.1.52.prSi uir uxori donationis causa rem uilius locauerit, locatio nulla est: cum autem depositum inter eas personas minoris donationis causa aestimatur, depositum est.
[PAPINIANUS, in the tenth book of Questions.] If a husband, for the purpose of a donation, lets a property to his wife at a lower price, the lease is void; but when a deposit between these persons is valued at a lower rate for the purpose of a donation, the deposit is valid.
haec ideo tam uarie, quia locatio quidem sine mercede certa contrahi non potest, depositum autem et citra aestimationem quoque dari potest.
These cases are treated so differently because a lease cannot be contracted without a fixed rent, whereas a deposit can also be given without any valuation.
§24.1.52.1Uxor uiro fructum fundi ab herede suo dari, quod si datus non fuisset, certam pecuniam mortis causa promitti curauit: defuncto uiro uiua muliere stipulatio soluitur, ut traditio, quae mandante uxore mortis causa facta est: nam quo casu inter exteros condictio nascitur, inter maritos nihil agitur.
A wife arranged for the fruit of an estate to be given to her husband by her heir, and, if it should not have been given, for a certain sum of money to be promised to him mortis causa: if the husband dies while the woman is still living, the stipulation is dissolved, just like a delivery which was made mortis causa by the order of the wife; for in a case where a condictio arises between strangers, nothing is effected between husband and wife.
