[ULPIANUS libro primo ad Sabinum. ] §28.1.18.prIs cui lege bonis interdictum est testamentum facere non potest et, si fecerit, ipso iure non ualet: quod tamen interdictione uetustius habuerit testamentum, hoc ualebit.
[ULPIANUS, in the first book on Sabinus.] A person who has been interdicted by law from managing his property cannot make a testament, and if he does make one, it is void by operation of law; however, any testament that he had already made prior to the interdiction shall be valid.
merito ergo nec testis ad testamentum adhiberi poterit, cum neque testamenti factionem habeat.
Consequently, he cannot even be employed as a witness to a testament, since he does not possess the capacity to make a testament.
§28.1.18.1Si quis ob carmen famosum damnetur, senatus consulto expressum est, ut intestabilis sit: ergo nec testamentum facere poterit nec ad testamentum adhiberi.
If anyone is condemned on account of a libelous poem, it is expressly provided by a decree of the senate that he shall be disqualified from testation; therefore, he can neither make a testament nor be employed as a witness to a testament.
