[ULPIANUS libro trigesimo secundo ad edictum. ] §18.4.11.prNam hoc modo admittitur esse uenditionem 'si qua sit hereditas, est tibi empta', et quasi spes hereditatis: ipsum enim incertum rei ueneat, ut in retibus.
[ULPIAN, On the Edict, book 32.] For in this way it is admitted that there is a sale, namely, 'if there be any inheritance, it is bought by you,' and as it were a hope of an inheritance; for the very uncertainty of the thing is sold, as in the case of a cast of a net.
