[ULPIANUS libro quinto ad Sabinum. ] §35.1.2.prCondicionum quaedam sunt, quae quandoque impleri possunt etiam uiuo testatore, ut puta 'si nauis ex Asia uenerit', nam quandoque uenerit nauis, condicioni paritum uidetur: quaedam, quae non nisi post mortem testatoris 'si decem dederit' 'si Capitolium ascenderit': nam ut paruisse quis condicioni uideatur, etiam scire debet hanc condicionem insertam: nam si fato fecerit, non uidetur obtemperasse uoluntati.
[ULPIANUS in the fifth book on Sabinus.] Of conditions, some are such as can be fulfilled at any time even during the lifetime of the testator, as for instance, 'if a ship should come from Asia'; for whenever the ship comes, the condition is deemed to have been complied with. Others are such as cannot be fulfilled except after the death of the testator, like 'if he should give ten', or 'if he should ascend the Capitol'; for in order that anyone may be deemed to have complied with a condition, he must also know that this condition has been inserted; for if he has done it by chance, he is not deemed to have complied with the testator's will.
