[PAULUS libro septimo quaestionum. ] §37.11.12.prUt scriptus heres adgnoscere possit bonorum possessionem, exigendum puto, ut et demonstratus sit propria demonstratione et portio adscripta ei inueniri possit, licet sine parte institutus sit: nam qui sine parte heres institutus est, uacantem portionem uel alium assem occupat.
[PAULUS, in the seventh book of Questions.] In order for an appointed heir to be able to accept possession of the goods, I think it must be required both that he is identified by a specific designation and that the share assigned to him can be found, even though he was instituted without a specific share; for he who is instituted heir without a share occupies a vacant share or another whole estate.
quod si ita heres scriptus sit, ut interdum excludatur a testamento, eo quod non inuenitur portio, ex qua institutus est, nec bonorum possessionem petere potest.
But if he is so appointed heir that he is sometimes excluded from the will on the ground that the share from which he was instituted is not found, he cannot claim possession of the goods either.
id euenit, si quis ita heredem instituat: 'Titius quanta ex parte priore testamento eum heredem scriptum habeo, heres esto' uel 'quanta ex parte codicillis scriptum eum habeo, heres esto', sic scriptus non inueniatur.
This happens if anyone institutes an heir as follows, and he is not found to be so appointed: 'Let Titius be heir to the same extent as I have him appointed heir in my prior will' or 'let him be heir to the same extent as I have him appointed in the codicils'.
quod si ita scripsero: 'Titius, si eum priore testamento ex semisse scriptum heredem habeo' uel 'si eum codicillis ex semisse heredem scripsero, ex semisse heres esto', tunc accipiet bonorum possessionem qualsi sub condicione heres scriptus.
But if I write as follows: 'Let Titius be heir to a half share, if I have him appointed heir to a half share in my prior will' or 'if I shall have written him heir to a half share in the codicils, let him be heir to a half share', then he will receive possession of the goods as an heir appointed under a condition.
