[IDEM libro secundo pandectarum. ] §28.5.63.prIn tempus capiendae hereditatis institui heredem posse beneuolentiae est, ueluti 'Lucius Titius cum capere potuerit, heres esto': idem et in legato.
[THE SAME, from the second book of the Pandects.] That an heir can be instituted with reference to the time of taking the inheritance is a matter of favor, for example: 'Let Lucius Titius be heir when he is able to take it'; the same also applies to a legacy.
§28.5.63.1Quotiens non apparet, quis heres institutus sit, institutio non ualet (quippe euenire potest, si testator complures amicos eodem nomine habeat et ad designationem singulari nomine utatur): nisi ex aliis apertissimis probationibus fuerit reuelatum, pro qua persona testator senserit.
Whenever it is not clear who has been instituted heir, the institution is invalid (for indeed it can happen if the testator has several friends of the same name and uses a single name for designation); unless it has been revealed by other most clear proofs which person the testator intended.
