[MARCIANUS libro tertio regularum. ] §34.5.18.prSed et in illo quaeritur, si pariter pupillus et qui ei substitutus erat frater necessarius decesserit, an frater fratri exsistat heres an contra: uel si duo inuicem necessarii substituti sunt et una perierint, an heredes exstitisse uideantur: uel alter alteri (hoc est si inuicem) hereditatem rogati fuerint restituere.
[MARCIANUS, from the third book of Rules.] But it is also questioned in this case: if a pupillus and his brother, who had been substituted for him as a necessary heir, have perished together, whether the brother becomes the heir to his brother, or the reverse; or if two persons have been substituted for each other as necessary heirs and have perished together, whether they are deemed to have become heirs; or if one has been requested to restore the inheritance to the other (that is, if they were requested reciprocally).
in quibus casibus si pariter decesserint nec appareat, quis ante spiritum emisit, non uidetur alter alteri superuixisse.
In which cases, if they have perished together and it is not apparent who drew his last breath first, neither is deemed to have survived the other.
§34.5.18.1Sed et circa legem Falcidiam, si dominus cum seruis simul uita functus sit, serui, quasi in bonis eius mortis tempore fuerint, non computantur.
But also concerning the Falcidian law, if a master has departed this life at the same time as his slaves, the slaves are not computed as though they were in his property at the time of his death.
