[PAULUS libro nono quaestionum. ] §31.0.81.prSi quis testamento facto a filiis suis, quos heredes instituisset, fideicommissa reliquisset non ut a legitimis heredibus, sed ut a scriptis, et testamentum aliquo casu irritum factum sit, filii ab intestato uenientes fideicommissa ex testamento praestare compelli non possunt.
[PAULUS, from the ninth book of questions.] If anyone, having made a will, had left trusts to be performed by his sons whom he had appointed as heirs, not as statutory heirs but as written heirs, and the will has by some event been rendered void, the sons, succeeding as heirs on intestacy, cannot be compelled to perform the trusts based on the will.
