[ULPIANUS libro octauo ad Sabinum. ] §29.2.32.preres institutus si putet testatorem uiuere, quamuis iam defunctus sit, adire hereditatem non potest.
[ULPIANUS in the eighth book on Sabinus.] An appointed heir, if he thinks that the testator is alive, although the latter is already deceased, cannot accept the inheritance.
§29.2.32.1Sed et si scit se heredem institutum, sed utrum pure an sub condicione ignoret, non poterit adire hereditatem, licet pure heres institutus sit, et sub condicione licet paruerit condicioni.
But also, if he knows that he has been appointed heir, but is ignorant whether it is unconditionally or under a condition, he will not be able to accept the inheritance, even though he has been appointed unconditionally, or, if under a condition, although he has fulfilled the condition.
§29.2.32.2Sed et si de condicione testatoris incertus sit, pater familias an filius familias sit, non poterit adire hereditatem, etsi eius condicionis sit in ueritate, ut testari potuerit.
But also, if he is uncertain about the status of the testator, whether he is a pater familias or a filius familias, he will not be able to accept the inheritance, even though in truth the testator was of such a status that he was able to make a will.
