[ULPIANUS libro quarto disputationum. ] §38.2.19.prSi patronus ex minore parte quam legitima heres institutus falsum testamentum dixisset nec optinuisset, non est ambiguum contra tabulas ei non deferri bonorum possessionem, eo quod facto suo perdidit hereditatem, cum temere falsum dixit.
[ULPIANUS, in the fourth book of Disputations.] If a patron, having been instituted heir for a smaller share than the lawful portion, should allege that the will is forged and fail to prove it, there is no doubt that the possession of goods contrary to the tablet of the will is not granted to him, because he lost the inheritance by his own act when he rashly alleged the forgery.
§38.2.19.1Quod si ex debita parte fuerit institutus, siue adiit siue non, contra tabulas bonorum possessione repellitur, quasi debitam sibi portionem acceperit. nec poterit contra tabulas bonorum possessionem petere.
But if he was instituted for the portion due to him, whether he entered upon the inheritance or not, he is barred from the possession of goods contrary to the tablet of the will, as if he had received the portion due to him; nor will he be able to claim the possession of goods contrary to the tablet of the will.
