§45.1.46.1Id autem, quod in facto est, in mortis tempus conferri non potest, ueluti: 'cum morieris, Alexandriam uenire spondes?' §45.1.46.2Si ita stipulatus fuero 'cum uolueris', quidam inutilem esse stipulationem aiunt, alii ita inutilem, si antequam constituas, morieris, quod uerum est.

§45.1.46.3Illam autem stipulationem 'si uolueris, dari?' inutilem esse constat.
But it is well established that the following stipulation is ineffective: 'to be given if you wish?'
